What is the FD Calculator?
A fixed deposit is a lump-sum bank deposit where interest is added over a fixed tenure. This calculator estimates maturity value, total interest and effective annual yield from the deposit amount, annual rate, tenure and compounding frequency.
Formula used
Formula: Maturity = Principal x (1 + annual rate / compounding frequency)^(compounding frequency x years). Interest = Maturity - Principal.
For FD estimates, keep the interest rate annual and choose the compounding option that matches the bank offer you are comparing.
Input guide
| Principal | The one-time amount placed in the fixed deposit. |
|---|---|
| Annual rate | The yearly interest rate offered by the bank or financial institution. |
| Compounding | How often interest is added to the deposit balance. |
| Tenure | The period for which the money remains deposited. |
Real-world examples and use cases
- Compare two bank FD offers with the same deposit amount and tenure.
- Check how a longer tenure changes interest earned.
- Estimate renewal value before reinvesting a matured deposit.
- Compare FD maturity with RD, SIP or compound interest alternatives.
Common mistakes
- Entering a monthly rate in the annual rate field.
- Ignoring TDS or tax on interest.
- Comparing quarterly and monthly compounding without changing the input.
- Assuming premature withdrawal will give the same maturity value.
Limitations of this calculator
The calculator does not include tax deduction, premature withdrawal penalty, senior-citizen rate changes, auto-renewal terms or bank-specific rounding.
Frequently Asked Questions
Does FD maturity include tax?
No. The result is a pre-tax estimate unless you manually adjust the rate or interest value.
Why does compounding frequency matter?
More frequent compounding credits interest more often, which can slightly increase maturity at the same annual rate.
Can I compare two banks with this page?
Yes. Enter the same principal and tenure, then change the rate or compounding option for each bank offer.
Helpful tips
