How to use this FD and RD calculator
- Choose FD for a lump sum or RD for a monthly deposit.
- Enter the amount, the interest rate your bank offers and the tenure.
- For an FD, pick how often interest compounds, or switch to a payout FD to see the monthly or quarterly income instead.
- Add your tax slab to see how much of the interest you keep after tax.
- Check the chart and the year-by-year table for the growth path.
Worked examples
| Deposit | Rate and tenure | Interest paid | Maturity |
|---|---|---|---|
| FD of ₹1,00,000 | 7% for 5 years, quarterly | ₹41,478 | ₹1,41,478 |
| FD of ₹5,00,000 | 7% for 5 years, quarterly | ₹2,07,389 | ₹7,07,389 |
| RD of ₹5,000 a month | 7% for 5 years, quarterly | ₹59,664 on ₹3,00,000 deposited | ₹3,59,664 |
Interest rates differ by bank, tenure and depositor, so replace 7% with the rate on your deposit receipt or the bank's current rate card.
FD versus RD
An FD locks in a lump sum you already have, and every rupee earns interest for the full tenure. An RD builds a sum from monthly savings, so each deposit earns interest only from the month it is made, which is why the maturity is lower than an FD with the same total money. An RD suits a salary earner who wants a saving habit; an FD suits a windfall. For long-term growth beyond deposit rates, compare with the PPF calculator and the SIP calculator.
What the tax figure means
The post-tax figure assumes all of the interest is taxed at the slab you choose, plus 4% cess. In practice the interest is taxed year by year as it accrues, so the timing differs, and if your total income is low you may pay less or nothing. It is a quick guide to the real return after tax, which is often lower than the headline rate and can be close to inflation for people in the 30% slab.
Limits of this calculator
It assumes a fixed rate for the whole tenure, no premature withdrawal penalty, no senior citizen rate uplift unless you enter it in the rate, and standard compounding. Banks count days and quarters in slightly different ways, so the maturity value on your receipt may differ by a small amount.
