FD calculator
Enter the amount, the rate your bank offers and the tenure in months. You get the maturity amount and the interest earned.
For a post office time deposit, use the post office FD calculator, which already has the government rates.
How it's calculated
- Interest is added to the deposit at set intervals and then earns interest itself. Your FD receipt says how often; quarterly is the default here.
- Maturity = P × (1 + r / k)^(k × t), where P is the deposit, r the yearly rate, k the times interest is added in a year and t the years.
- The effective yield is what the rate is worth over a full year once compounding is counted.
An example
₹1 lakh for one year at 7% compounded quarterly matures at ₹1,07,185.90, an effective yield of about 7.19%.
Frequently asked questions
Is FD interest taxed?
Yes. It is added to your income and taxed at your slab rate. The bank may also deduct TDS when the interest passes the threshold.
Why does my bank show a slightly different figure?
Banks count days exactly and may round each quarter. For tenures that are not whole quarters the result can differ by a few rupees.
What about senior citizens?
Enter the rate your bank quotes you. If it offers a separate senior citizen rate, use that one.
