Is a fixed deposit's post-tax return positive after inflation in India?
A 7% FD sounds safe, but for a 30% bracket taxpayer, after tax (4.9%) and 5% inflation, the real return is about −0.1% — your purchasing power slightly shrinks despite the 'guaranteed' return. FDs preserve nominal capital but rarely build real wealth. Here's the full maths and when FDs still make sense.

Fixed deposits feel safe — the rate is guaranteed, the capital is protected, and the bank is reliable. But "safe" in nominal terms is not the same as "safe" in real terms. After accounting for tax and inflation, a fixed deposit's real return is often near zero or negative, which means your purchasing power barely grows or actually shrinks. This article shows the maths.
The three layers between the headline rate and your real return
When a bank advertises a 7% FD, that 7% is the nominal pre-tax return. Two things reduce it:
1. Tax. FD interest is taxable at your income slab rate.
2. Inflation. Rising prices reduce what your money can buy.
The number that actually matters is the real post-tax return — what is left after both.
The calculation, step by step
Starting point: FD at 7% per annum.
Step 1 — subtract tax (post-tax nominal return):
| Tax slab | Post-tax return on a 7% FD |
| 0% (income below taxable limit) | 7.00% |
| 5% | 6.65% |
| 20% | 5.60% |
| 30% | 4.90% |
Formula: post-tax return = nominal rate × (1 − tax rate)
Step 2 — subtract inflation (real post-tax return):
Assume inflation of 5% per annum (close to the RBI's medium-term target band).
| Tax slab | Post-tax nominal | Real return (post-tax − inflation) |
| 0% | 7.00% | +2.00% |
| 5% | 6.65% | +1.65% |
| 20% | 5.60% | +0.60% |
| 30% | 4.90% | −0.10% |
For a taxpayer in the 30% bracket, a 7% FD produces a real return of approximately −0.10% — meaning your purchasing power slightly decreases over time, despite the "guaranteed" 7% headline.
Why this matters: the erosion is silent
The FD balance always goes up in rupee terms — your ₹1 lakh becomes ₹1.07 lakh after a year. It looks like growth. But if prices rose 5% and you paid 30% tax on the interest, the ₹1.07 lakh buys slightly less than the ₹1 lakh did a year earlier.
Over long periods, this is significant. ₹10 lakh in an FD at a real return of −0.1% for 20 years has roughly the same (or slightly less) purchasing power at the end as at the start — despite the nominal balance more than doubling.
◇ Quick check: Take your FD rate. Multiply by (1 − your tax rate) to get post-tax return. Subtract current inflation (~5%). If the result is near zero or negative, your FD is preserving nominal capital but not growing real wealth.
When FDs still make sense
This analysis is not an argument against FDs entirely. FDs serve specific, valid purposes:
Emergency funds: The real return is secondary to safety and liquidity. An emergency fund's job is to be there when needed, not to grow — FDs (or liquid funds) are appropriate.
Short-term goals (1–3 years): Money you need soon should not be in volatile equity. An FD's capital protection matters more than its real return for near-term goals.
Capital preservation for retirees: Those who cannot tolerate volatility and need predictable income may accept a low real return for certainty.
Senior citizens: Often in lower tax brackets, with higher FD rates (senior citizen FDs) and a ₹50,000 interest exemption under Section 80TTB — improving the real return meaningfully.
The comparison: FD vs equity over the long term
For long-term goals (7+ years), the real return gap between FDs and equity is large.
| FD (30% bracket) | Equity (long-term, illustration) | |
| Nominal return | 7% | 11–12% |
| Post-tax | 4.9% | ~10–11% (LTCG at 12.5% above ₹1.25L) |
| Real (after 5% inflation) | ~−0.1% | ~5–6% |
Equity returns are market-linked, not guaranteed, and volatile. FD returns are guaranteed.
For long-horizon goals, parking everything in FDs means your money barely keeps pace with inflation, while equity (with volatility) has historically grown real wealth. The trade-off is certainty vs growth.
⚠ Common mistake: keeping long-term money in FDs for "safety"
Many salaried employees keep their entire savings in FDs because they feel safe. For an emergency fund or a near-term goal, this is correct. But for retirement savings 20–30 years away, FDs are arguably the riskier choice — they guarantee that your real wealth will barely grow, while inflation steadily erodes purchasing power. The "safety" of an FD protects nominal capital but not your future buying power.
Bottom line
- An FD's headline rate is nominal and pre-tax; the number that matters is real post-tax return
- At 7% FD, 30% tax, and 5% inflation, the real return is approximately −0.1% — purchasing power slightly shrinks
- FDs preserve nominal capital but generally do not build real wealth for higher-bracket taxpayers
- FDs are appropriate for emergency funds, short-term goals, and capital preservation — not for long-term wealth building
- For long-horizon goals, equity has historically delivered positive real returns; FDs have not, after tax and inflation, for high-bracket taxpayers
Frequently asked questions
Q: My FD gives 7.5%. Isn't that beating inflation?
A: In nominal terms, yes. But after tax (at 30%, 7.5% becomes 5.25%) and inflation (5%), the real return is approximately 0.25% — barely positive. In the 20% bracket, 7.5% becomes 6% post-tax, and approximately 1% real. The headline rate is misleading until you adjust for both tax and inflation.
Q: Are tax-saving FDs (5-year) any better?
A: The interest on tax-saving FDs is still fully taxable, so the real post-tax return is the same as a regular FD. The only benefit is the upfront 80C deduction (old regime). The 5-year lock-in does not improve the real return on the interest.
Q: What about senior citizens?
A: Senior citizens often get higher FD rates (0.25–0.5% more), are frequently in lower tax brackets, and have a ₹50,000 interest exemption under Section 80TTB. These factors meaningfully improve the real return for them, making FDs more reasonable for senior citizens than for high-earning younger taxpayers.
Q: Should I avoid FDs completely?
A: No. FDs are the right tool for emergency funds and short-term goals where capital safety matters more than growth. The point is to match the instrument to the goal: FDs for safety and liquidity; equity (with volatility) for long-term real growth.
