Most POMIS articles hand you a formula and call it analysis. Multiply your principal by 7.4%, divide by 12, done. What they skip is the part that actually matters: after income tax, after you compare it honestly to SCSS and FD, and after you factor in what RBI is doing with rates right now, is POMIS still the right call for you? That depends on two things about you specifically. Everything else is noise.
1. The One-Question Framework: Age and Tax Slab
Two facts about you settle this question before any calculation. Everything else, the rate history, the comparison tables, the strategy guides, all of that comes after these two.
Are you 60 or above? If yes, SCSS exists and you should be using it first. SCSS pays 8.2% on up to ₹30 lakh with the same sovereign backing. That is 80 basis points more than POMIS and three times the investment ceiling. If you are 60+ and sitting in POMIS while your SCSS limit has headroom, you are leaving money on the table. POMIS only enters the picture for the corpus that exceeds SCSS's ₹30L cap, or if you specifically need monthly payouts (SCSS pays quarterly).
What is your tax bracket? At 0%, POMIS hands you the full 7.4%. At 30%, you keep 5.09%. Same scheme, same government guarantee, same post office. A 231 basis point difference from income tax alone. This single variable changes whether POMIS is a great deal or a mediocre one. Section 3 has the full table.
2. What POMIS Actually Pays: The Plain Math
POMIS is a simple instrument. No compounding, no market linkage, no surprises. Principal × 7.4% ÷ 12. The same rupee amount lands in your post office savings account every single month for 60 months. At the end of 5 years, your full principal comes back. That is the entire deal.
| Investment Amount | Monthly Income (7.4%) | Annual Income | Total Interest (5 Yrs) | Maturity Value |
|---|---|---|---|---|
| ₹1,00,000 | ₹617 | ₹7,400 | ₹37,000 | ₹1,00,000 |
| ₹3,00,000 | ₹1,850 | ₹22,200 | ₹1,11,000 | ₹3,00,000 |
| ₹5,00,000 | ₹3,083 | ₹37,000 | ₹1,85,000 | ₹5,00,000 |
| ₹7,00,000 | ₹4,317 | ₹51,800 | ₹2,59,000 | ₹7,00,000 |
| ₹9,00,000 (max single) | ₹5,550 | ₹66,600 | ₹3,33,000 | ₹9,00,000 |
| ₹15,00,000 (max joint) | ₹9,250 | ₹1,11,000 | ₹5,55,000 | ₹15,00,000 |
The no-compounding part is important to understand. ₹9 lakh in POMIS earns exactly ₹3,33,000 over 5 years. Predictable to the rupee. But ₹9 lakh in a 7% FD compounding quarterly earns around ₹3,58,000 over the same period, more, despite the lower stated rate, because the interest compounds. POMIS is not trying to grow your money. It is trying to pay you a fixed income from your money. If you need that monthly cash flow, POMIS is the right tool. If you are trying to build a corpus, you need something else.
Enter your investment amount, account type, and see premature withdrawal penalties, post-tax yield by slab, and the POMIS + RD compound return all in one place.
Open POMIS Calculator3. The Tax Reality: What You Keep After Income Tax
Here is the part most POMIS articles gloss over. The post office does not deduct any TDS. Your full ₹5,550 arrives every month, untouched. It feels like tax-free income. It is not. POMIS interest is fully taxable under Income from Other Sources, same rules as FD interest. No TDS just means you handle the compliance yourself, declaring it in Schedule OS of your ITR and paying advance tax quarterly if your total liability crosses ₹10,000 a year.
No 80C benefit either. Unlike PPF deposits, your POMIS investment does not reduce your taxable income by a single rupee. You get the monthly payout, you pay tax on it, that is the deal. The table below shows what “7.4%” actually becomes at each bracket.
| Tax Slab (New Regime) | Effective Rate (incl. 4% cess) | Post-Tax POMIS Yield | Monthly Income ₹9L | Annual Income ₹9L | 5-Year Total |
|---|---|---|---|---|---|
| 0% (below ₹3L or 87A rebate) | 0% | 7.40% | ₹5,550 | ₹66,600 | ₹3,33,000 |
| 5% (₹3L to ₹7L) | 5.2% | 7.02% | ₹5,261 | ₹63,132 | ₹3,15,660 |
| 10% (₹7L to ₹10L) | 10.4% | 6.63% | ₹4,972 | ₹59,664 | ₹2,98,320 |
| 15% (₹10L to ₹12L) | 15.6% | 6.25% | ₹4,687 | ₹56,244 | ₹2,81,220 |
| 20% (₹12L to ₹15L) | 20.8% | 5.86% | ₹4,395 | ₹52,740 | ₹2,63,700 |
| 30% (above ₹15L) | 31.2% | 5.09% | ₹3,817 | ₹45,804 | ₹2,29,020 |
Cess at 4% included. New tax regime slabs used. Post-tax yield = pre-tax rate × (1 minus effective tax rate). ITR declaration is mandatory; no TDS does not mean tax-exempt.
Look at the 0% row. A retired individual on the new tax regime whose total income, including POMIS interest, stays below ₹7 lakh gets the 87A rebate and pays zero tax. On ₹9 lakh POMIS that is ₹66,600 a year at 7.4% effective yield. Zero tax, sovereign guarantee, monthly payout. For this investor specifically, POMIS is genuinely hard to beat anywhere in Indian fixed income. Use our Income Tax Calculator to verify exactly where your income lands before deciding on the full ₹9L.
4. POMIS vs SCSS: The 80 Basis Point Question
If you are 60 or above, stop reading everything else and focus here. The Senior Citizens Savings Scheme pays 8.2% versus POMIS's 7.4%. Both are sovereign-guaranteed, both are backed by the Ministry of Finance. The only difference is SCSS pays more, allows a larger investment, and is only available to you if you are 60+.
| Feature | POMIS | SCSS | Advantage |
|---|---|---|---|
| Interest Rate | 7.40% p.a. | 8.20% p.a. | SCSS +80bps |
| Max Investment | ₹9L (single) / ₹15L (joint) | ₹30L (joint + individual combined) | SCSS 2× ceiling |
| Monthly Income ₹9L | ₹5,550 | ₹6,150* | SCSS +₹600/month |
| Payout Frequency | Monthly | Quarterly | POMIS (if monthly needed) |
| TDS | No TDS | TDS above ₹50,000/yr | POMIS |
| Tenure | 5 years | 5 years (extendable 3 yrs) | SCSS (extension option) |
| Eligibility | All residents, any age | 60+ only | POMIS (wider access) |
| Risk | Nil (Sovereign) | Nil (Sovereign) | Equal |
*SCSS payout quarterly; monthly equivalent shown. SCSS TDS applies to interest above ₹50,000/year; submit Form 15H if total income is below taxable limit.
If you are 60+, fill SCSS first. That is not a preference, it is the only financially sensible order. On ₹9 lakh, SCSS pays ₹36,000 more over 5 years. On the full ₹30L SCSS ceiling, the gap is ₹1,20,000. There is no scenario where you should open POMIS while SCSS headroom remains unused.
The one real reason to run both: SCSS pays quarterly, POMIS pays monthly. If you genuinely need money hitting your account every single month, you might pair a maxed SCSS with a small POMIS timed for the months SCSS does not pay. But you get there only after filling SCSS to ₹30L. Not before.
5. POMIS vs Bank FD: Why POMIS Wins on Structure
Most people reading this already have money in a bank FD somewhere. So let's be direct about how POMIS compares. On rate alone: POMIS at 7.4% beats SBI's 5-year FD at 6.5%, HDFC at 7.0%, ICICI at 6.9%. That is 40 to 90 basis points in POMIS's favour. But the rate is actually the smaller argument.
The safety is different. Your bank FD has DICGC insurance up to ₹5 lakh per bank. If you have ₹9 lakh in a single FD and that bank goes under, ₹4 lakh is not covered. POMIS is a Government of India obligation. There is no upper limit on what is protected because the government is not going to default on its own small savings scheme. That is a meaningfully different level of safety for conservative investors.
No TDS is a bigger deal than it sounds. Your bank FD deducts 10% TDS the moment annual interest crosses ₹40,000. On ₹9 lakh at 6.5%, you cross that limit easily. The bank clips your interest before you even see it. POMIS pays you in full every month. You handle the tax in your ITR. If your total income is below the taxable threshold, this difference means you keep money you would otherwise have to claim back.
Rate lock matters a lot right now. Bank FDs typically run 1-3 years and roll over at whatever rate exists at renewal. RBI cut rates twice in 2025. The investor who opened a 1-year FD at 7.5% in 2023 is now renewing at 6.5-6.8%. POMIS opened today at 7.4% stays at 7.4% for the full 5 years. That rate lock is increasingly valuable as the easing cycle continues.
Use the Rate Lock Value tab in the POMIS calculator to calculate exactly how much extra you earn over 5 years by locking today versus waiting for a rate cut.
Open Rate Lock CalculatorWhere FD genuinely wins: flexibility. FDs come in tenures from 7 days to 10 years. POMIS is 5 years, fixed, no exceptions. If you are parking money for 18 months or need access before Year 5, POMIS is the wrong instrument. Use a short FD for that. POMIS is for money you genuinely do not need to touch for 5 years and want converted into a predictable monthly income stream.
6. POMIS vs PPF: Two Instruments, Two Jobs
Comparing POMIS and PPF is the wrong framing. They are not competing for the same job. POMIS pays you monthly from a lump sum you already have. PPF builds a lump sum from monthly contributions over 15 years. One is a payout machine, the other is an accumulation machine.
For a 30% bracket investor, PPF's EEE tax status makes the effective pre-tax equivalent yield around 10.14%. No FD, POMIS, or SCSS comes close on a post-tax basis. But there is no monthly income from PPF while it is growing. You lock money in for 15 years, partial withdrawals begin after 7, and the big payout comes at the end. If you need income today, PPF cannot help you.
The Specific Case Where PPF Wins Completely
If you are in the 30% tax bracket and have a horizon of 15+ years, PPF is not just better than POMIS, it is in a different category entirely. The EEE status means your contributions are deducted under 80C, your interest is not taxed annually, and the maturity amount is tax-free. For a 30% bracket investor putting ₹1.5L a year into PPF, the 80C saving alone is ₹46,800 annually. That is money you would have paid in tax, now compounding inside PPF at 7.1%. The effective return, accounting for the tax saving, is closer to 10%.
POMIS cannot match that. If you are under 50, still earning, in the 20%+ bracket, and have a 15-year window, PPF should take priority over POMIS for any rupee that can be locked up that long. POMIS comes into the picture when you need income now, not when you are still building the corpus.
The practical split most people end up with: max your ₹1.5L PPF contribution every April (take the 80C benefit and let it compound), and put any additional investable surplus into POMIS if you need monthly income, or into equity if you are still 10+ years from needing that income. PPF is the wealth builder. POMIS is the income generator. They are not rivals.
7. POMIS vs Mutual Fund SWP: The Tax Bracket Tipping Point
This is where the honest answer gets complicated. At 0-10% tax brackets, POMIS is genuinely excellent for monthly income. At 30% bracket with a 10+ year horizon, a well-run equity SWP starts looking dramatically better on paper.
An equity SWP at 10-12% historical returns, taxed at 12.5% LTCG after one year, gives you an effective post-tax yield of 8.7-10.4%. POMIS gives a 30% bracket investor 5.09% post-tax. Over 10 years, that gap compounds into a significant difference. But here is what the SWP comparison always downplays: equity markets can fall 40% in a bad year. If they do in Year 2 of your retirement, your monthly withdrawals are now eating into a much smaller corpus. POMIS never does this to you. The ₹5,550 shows up whether Sensex is at 40,000 or 90,000.
The approach that actually works in practice: cover fixed monthly expenses, rent, groceries, utilities, healthcare, from POMIS or SCSS. Never make these market-dependent. Keep any surplus in equity MF with a conservative 4-5% annual SWP. Your essential spending is protected regardless of what markets do. Your discretionary spending benefits from market growth. That is the sensible balance, not an either-or choice.
The Real Numbers: POMIS vs SWP at 30% Bracket Over 10 Years
Let us run the actual comparison rather than talking around it. ₹9 lakh invested. 10-year horizon. 30% tax bracket.
POMIS (two consecutive 5-year accounts): post-tax yield 5.09%. You receive approximately ₹3,817/month. Over 10 years, total post-tax income is approximately ₹4,58,040. Principal returned at each maturity. Net gain on ₹9L: ₹4,58,040 in income.
Equity SWP: ₹9L growing at 10% annually (conservative historical average). After 3 years, corpus is approximately ₹11.97L. SWP withdrawal at 5% annually: ₹49,900/year, or ₹4,158/month, post-LTCG tax at 12.5%. Over 10 years, total post-tax income is approximately ₹5,00,000+, and the remaining corpus is still larger than the original ₹9L in real terms, assuming markets continue performing.
The SWP wins on paper by a meaningful margin. But “assuming markets continue performing” is doing a lot of work in that sentence. 2008, 2020 and 2022 were years equity investors wished they had a guaranteed floor. If you have the temperament for market volatility and a genuine 10-year horizon, the SWP case is real. If market drawdowns in a bad year would cause you to stop the SWP and crystallise losses, POMIS is the better choice practically, not just theoretically.
8. The Rate Lock Advantage: Why 2026 Timing Matters
RBI cut the repo rate by 50 basis points in 2025. Small savings rates follow the repo direction with roughly a 1-2 quarter lag. The 7.4% POMIS rate you see right now may well be 6.9% or lower by the next revision. Nobody knows exactly when or by how much, but the direction is fairly clear.
Here is what makes this matter: whatever rate your account opens at is your rate for all 60 months. Full stop. If you open today at 7.4% and the government cuts POMIS to 6.9% in July, your account keeps earning 7.4% through to 2031. On ₹9 lakh, the difference between 7.4% and 6.9% is ₹2,250 per year, ₹11,250 over the full tenure.
This is not market timing. You are not predicting anything. The logic is simple: if rates might fall (and they might), opening now locks the better rate. If rates rise instead, you can open a second account at the higher rate when this one matures in 5 years. There is no meaningful downside to opening sooner rather than later.
POMIS Rate History: What Has Actually Happened to the Rate Over Time
The rate lock argument only matters if rates actually move. Here is what has happened to POMIS rates over the last several years: 6.60% from 2020 to mid-2022. 6.70% in October 2022. 7.10% in January 2023. 7.40% from April 2023 to present. The entire run from 6.6% to 7.4% happened in three quarters. Investors who locked in 6.6% in 2021 were stuck there until 2026 while new accounts opened at 7.4%.
The rate cycle is now in the other direction. Investors locking in today at 7.4% are in the same position those 2023 investors were, but on the way down instead of up. Nobody can guarantee the rate falls, but the RBI's own guidance and the 2025 rate cuts make it the higher-probability outcome over the next 12-18 months.
The practical takeaway: if you have been meaning to open a POMIS account and are waiting for a “better time,” there is no better time signal available to you than an RBI in easing mode. The best time to lock a fixed income rate is before the cuts arrive, not after. Use the Rate Lock tab in our POMIS calculator to see exactly how much the difference costs you in rupees.
9. The POMIS + RD Strategy: Making Your Interest Compound
POMIS interest does not compound inside the scheme. But you can make it compound outside it. The trick is simple: open a Post Office RD and set a standing instruction to transfer your POMIS payout into it every month. The ₹5,550 lands in your savings account, the standing instruction moves it to the RD. You never see it sitting idle.
Post Office RD currently pays 6.7% compounded quarterly. On ₹9L POMIS, redirecting ₹5,550 monthly into an RD for 60 months builds approximately ₹3,91,000 in RD corpus. Add your ₹9L POMIS principal back at maturity and you have ₹12,91,000 from an original ₹9L. Effective annual return: roughly 7.52%, not 7.4%. Small difference, but it adds up when you are talking about a ₹9L investment. Both accounts sit in the same post office ecosystem, so the standing instruction is straightforward to set up. The POMIS + RD tab in our calculator models this precisely.
10. Who Should Avoid POMIS
POMIS is excellent. It is not excellent for everyone. Three situations where something else serves you better:
- You are 60+ with SCSS space remaining. There is no argument for POMIS while your SCSS limit has room. Fill SCSS to ₹30L first. Every rupee. Then think about POMIS.
- You are in the 30% bracket and do not need the income urgently. At 5.09% post-tax, POMIS is doing less than half the work an equity SWP could do for a long-horizon investor comfortable with market cycles. If capital preservation is your top priority, ignore this. If wealth building is, POMIS alone is not enough for your high-bracket money.
- You might need this money in the first year. POMIS blocks every withdrawal for the first 12 months. No exceptions. If there is any possibility this corpus doubles as an emergency fund, put it somewhere liquid instead. Build your emergency fund separately before touching POMIS.
One more nuanced case worth checking: if your total income is close to ₹7 lakh under the new regime, adding ₹66,600 of POMIS interest annually might push you just over the 87A rebate limit. Suddenly the entire income becomes taxable, not just the excess. Run the numbers on our Income Tax Calculator before committing to the full ₹9L.
11. Household Maximisation: Getting More Than ₹9 Lakh into POMIS
The ₹9L limit is per individual, not per household. A couple where both spouses each open a single account gets ₹18L into POMIS, generating ₹11,100 per month combined. Add a joint account and the household total can reach ₹33L with roughly ₹20,350 per month.
Watch this closely: your share of any joint account counts against your personal ₹9L ceiling. Open a ₹10L joint account 50-50 with your spouse and each of you has used ₹5L of your individual limit, leaving only ₹4L each for separate accounts. Misplan the joint account and you shrink your household total unnecessarily.
The right order: max each person's individual ₹9L account first. Only then layer a joint account with whatever remains, sized so neither holder's proportionate share pushes them over their ₹9L ceiling. That gets you the maximum possible household allocation.
A Worked Example: Maximum Household POMIS Allocation
Arjun (58) and Priya (55) want to maximise their household POMIS before Arjun turns 60 and SCSS becomes available.
Step 1: Arjun opens an individual POMIS account at ₹9L. Monthly income: ₹5,550.
Step 2: Priya opens an individual POMIS account at ₹9L. Monthly income: ₹5,550.
Step 3: They open a joint account. Each has used their full ₹9L ceiling in Step 1-2. They cannot add a joint account without exceeding their individual limits.
Alternatively, if they had started with a ₹10L joint account (₹5L each), they would each have ₹4L remaining for individual accounts. Total household POMIS: ₹10L + ₹4L + ₹4L = ₹18L. Monthly income: ₹11,100. Same total as two individual accounts at ₹9L each, but with less flexibility since joint account closures require consent from all holders.
The lesson: for two adults both eligible for POMIS, two separate individual accounts at ₹9L each (₹18L total, ₹11,100/month) is almost always better than any joint account arrangement. Each person retains independent control, independent nomination, and independent maturity decisions. Joint accounts only add value when one person lacks the ₹9L individually and needs a partner's income to combine for a larger deposit.
12. Three Indian Investors: What POMIS Means for Each
Same scheme, same government guarantee, same post office. Three investors, three completely different answers to the question of whether POMIS is worth it.
What Each Investor Should Actually Do Next
Investor 1 (Retired, 63, 0% bracket): Open the maximum ₹9L individual POMIS account immediately and check SCSS eligibility. At 63, SCSS is available. If SCSS limit has headroom, fill SCSS first to ₹30L (₹20,500/month), then add POMIS for the monthly-vs-quarterly smoothing. Set up a standing instruction to direct POMIS interest into a Post Office RD for compounding. Total effort: one post office visit.
Investor 2 (Salaried, 48, 20% bracket): POMIS at ₹5L makes sense for the guaranteed income layer alongside SIPs. Make sure the ₹1.5L PPF annual contribution is already happening for 80C benefit and long-term compounding. Do not touch POMIS if the ₹5L is needed within 12 months for any purpose. Check total income including POMIS interest (₹37,000/year at ₹5L) against the current tax slab before investing the full amount.
Investor 3 (Business owner, 45, 30% bracket): Use POMIS only for the portion of corpus that genuinely cannot tolerate any market risk, perhaps 20-30% of investable surplus. The remaining 70-80% should be in equity mutual funds with a disciplined 5-year+ horizon. At 5.09% post-tax, POMIS in this bracket is a capital safety tool, not an income optimisation tool. Consider whether an arbitrage fund (taxed at 20% LTCG after one year) covers the “safe” allocation more efficiently.
13. The POMIS Decision Framework
You have read the comparisons. Here is what all of it collapses down to in practice.
| Your Situation | POMIS Verdict | Action |
|---|---|---|
| 60+ with SCSS limit not maxed | Avoid POMIS first | Max SCSS to ₹30L. Use POMIS only for additional surplus |
| Under 60, need guaranteed monthly income | Strong Yes | POMIS is your only sovereign monthly income option. Open immediately |
| 0-10% tax bracket, any age | Excellent | Full ₹9L. Effective yield 7.02-7.40% beats virtually everything at this risk level |
| 20% bracket, horizon 5-10 years | Good | POMIS for income floor. Supplement with equity SIP for long-term wealth |
| 30% bracket, horizon 10+ years | Selective | Use POMIS only for the portion you cannot afford to put at any market risk |
| Need liquidity within 1 year | No | POMIS blocks all withdrawal in Year 1. Use liquid FD or money market fund instead |
| RBI in rate-cutting cycle (current) | Open now | Lock 7.4% for 5 years before next quarterly revision reduces the rate |
The honest summary: POMIS does one thing exceptionally well. It turns a lump sum into guaranteed monthly income with zero risk and no market dependency. It is not meant to make you rich. For retirees, conservative investors, and anyone under 60 who needs predictable monthly cash flow, it is the best instrument available in its category. For high-bracket investors still in the accumulation phase, it belongs in the portfolio as the guaranteed income floor, not the whole portfolio. Use it for what it is, not for what you wish it were.
14. What to Do When Your POMIS Matures
Most POMIS guides stop at “open the account.” Nobody talks about what to do 5 years later when ₹9 lakh lands back in your post office savings account. That is actually a significant decision moment, and getting it wrong means losing months of interest unnecessarily.
Option 1: Reinvest in a New POMIS Account
The simplest choice. Walk into the post office, close the matured account, open a new one at the prevailing rate. If POMIS rates have fallen by then, this is the moment you lose the rate lock benefit of having opened early. If rates have risen, you benefit from the higher new rate. The key is not to leave the principal sitting in your savings account for weeks while you “think about it.” Most post office savings accounts pay 4% or less. Every month of delay costs you real interest.
Option 2: Shift to SCSS if You Are Now 60+
If you opened POMIS at 55 and your account matures at 60, you are now SCSS-eligible. Do not reinvest in POMIS. Shift the ₹9L into SCSS (8.2%), which now pays more. You have been waiting 5 years for this moment. Use it. If you opened POMIS at 58 with a spouse who is 56, the 5-year maturity brings your spouse to 61, also SCSS-eligible. Coordinate maturity timing with SCSS eligibility planning.
Option 3: Reconsider the Full Allocation
Maturity is a natural checkpoint to ask whether circumstances have changed. Your tax bracket may have shifted. Your income needs may have changed. The interest rate environment will be different. The ₹9L arriving at maturity is not automatically POMIS money again. Ask yourself: does my situation still fit the POMIS use case? If you are now in a higher bracket, maybe some of it belongs in a tax-efficient instrument. If you need more income and are 60+, maybe SCSS takes the full amount. Treat maturity as a financial review moment, not just a rollover event.
The Nomination and Succession Angle
One thing many POMIS investors do not think about until it is too late: what happens to the account if the holder passes away before maturity? The nominee can claim the principal plus any uncredited monthly interest. But they need to know the account exists, which post office branch holds it, and have the passbook and account number. If you are opening POMIS for a parent or spouse, make sure the account details are documented somewhere accessible. A surprising number of post office savings balances go unclaimed simply because families do not know about them.
