₹15 Lakh FD for 3 Years: Real Returns
A ₹15 Lakh fixed deposit at 6.5% compounds to ₹18.20 L in 3 years, and tax and inflation decide what you keep. FD interest is taxed at your income slab; within the new regime's ₹12 lakh rebate limit you pay nothing on it. The tables below show what you keep at the 0%, 5%, 20%, and 30% slabs, the monthly payout, and the real (inflation-adjusted) value.

Your FD matures to ₹17.53 L but is worth only ₹14.72 L in today's purchasing power. Your real return is -0.6% per year: you're losing money to inflation.
FD Growth Over Time
Chart from year 1 to year 3. Maturity Value changes from ₹15.8L to ₹17.5L. Principal changes from ₹15L to ₹15L. After Inflation changes from ₹14.9L to ₹14.7L.
| Metric | Amount |
|---|---|
| Principal | ₹15.00 L |
| Maturity (6.5%, pre-tax) | ₹18.20 L |
| Total Interest | ₹3.20 L |
| Monthly Interest Payout | ₹8,125/month |
| Your Tax Slab | Tax on Interest | Post-Tax Maturity | Real Value (6% inflation) |
|---|---|---|---|
| No tax (income ≤ ₹12L / Form 15G) | − | ₹18.20 L | ₹15.28 L |
| 5% (typical) | −₹16,006 | ₹18.04 L | ₹15.15 L |
| 20% | −₹64,022 | ₹17.56 L | ₹14.74 L |
| 30% | −₹96,033 | ₹17.24 L | ₹14.48 L |
At a 5% slab, tax of ₹16,006 leaves ₹18,04,105
The bank advertises ₹18.20 L at maturity. But FD interest is fully taxable at your slab. Many ₹15 Lakh depositors sit in the lower brackets: at a 5% slab, tax of ₹16,006 leaves you ₹18.04 L, and if your total income is within the ₹12 lakh rebate limit you keep the full amount. After 6% inflation over 3 years, the 5% figure is worth about ₹15.15 L in today's money. Use the slab table above to find the figure for your own bracket.
On a ₹15 Lakh FD at 6.5%, the monthly payout is ₹8,125 before tax
If you want regular income instead of compounding, a non-cumulative ₹15 Lakh FD at 6.5% pays roughly ₹8,125 per month (before tax). The principal stays locked until maturity. This suits retirees who need predictable cash flow more than capital growth.
₹18,04,105 in 3 years buys what ₹15,14,761 buys today
An FD guarantees your money in nominal terms but rarely in real terms. At a 6.5% rate, the post-tax return clears 6% inflation only at the 0% and 5% slabs: at 20% the 5.20% falls below inflation, and at 30% the 4.55% falls further behind. The deposit is "safe" from market swings, yet can quietly lose purchasing power. For goals 5+ years away, equity SIPs have historically preserved real value far better.
The right FD term ends close to the date you need the money
For a goal a few years away, the right term ends close to the spending date, and breaking the deposit early reduces the return. Check the premature-withdrawal penalty before committing to the term.
The ₹12 lakh rebate keeps the full ₹18,20,111
- Stay within the ₹12L rebate: under the new regime, if your total taxable income (including FD interest) is up to ₹12 lakh, the Section 87A rebate makes your tax zero: you keep the full maturity.
- Use a lower slab: at 5% or 20% you keep substantially more than the 30% figures shown here.
- Form 15G / 15H: if your total income is below the taxable limit, submit it to stop TDS.
- Senior citizens: get a higher rate (≈0.5% extra) and a larger ₹1,00,000 TDS threshold.
- Spread across financial years: splitting tenure or laddering can smooth annual interest.
