How to use FD calculator
1. Enter principal and rate
Use the annual interest rate from the bank, not the monthly equivalent.
2. Choose compounding
Quarterly matches a typical bank FD. Switch to monthly, half-yearly, or yearly if the deposit receipt says so.
3. Read maturity and interest
Maturity is principal plus interest. The interest line is the gain before tax deducted at source.
Compound interest, not simple interest
Maturity = P × (1 + r ÷ n)^(n × t). P is principal, r is the annual rate as a decimal, n is the number of compounds in a year, and t is the time in years. Quarterly means n is 4. A longer deposit at the same rate finishes higher because interest starts earning interest.
TDS is separate
Banks may deduct tax at source when interest crosses the threshold for the year, and the threshold depends on age and whether a PAN is on file. This page shows the contractual maturity. It does not subtract TDS.
Senior citizen rates
There is no separate button. Type the rate the bank offered. If that rate is half a percent higher, the maturity updates with it.
Questions
Why is quarterly compounding the default?
Most Indian bank fixed deposits compound interest every quarter. Change it if your receipt says monthly or half-yearly.
Does this deduct TDS?
No. The maturity shown is before tax deducted at source.
Can I calculate a short deposit?
Enter years as a decimal if you need part of a year, such as 1.5 for eighteen months. The formula compounds across that fraction.
Is the principal uploaded?
No. The maturity is calculated in your browser.
