How it’s calculated
FV = P × (1 + r/m)m×n, interest = FV − P, EAR = (1 + r/m)m − 1.
How to use this FD calculator effectively
Use this page to estimate fixed deposit maturity value, interest earned, and effective annual rate from principal, annual rate, term, and compounding frequency.
How it works
The calculator compounds a one-time principal at the selected frequency and reports the maturity value, gross interest, and EAR. EAR helps compare deposits that quote the same nominal annual rate but compound monthly, quarterly, or yearly.
When to use
Use it before comparing FD offers, checking a renewal quote, or explaining how compounding frequency changes the final payout. It is a gross calculation helper, not a bank statement.
Common mistakes to avoid
- Entering an after-tax or monthly rate in the annual-rate field without labeling it.
- Comparing deposits with different compounding frequencies without checking EAR.
- Assuming TDS, income tax, premature withdrawal penalties, or payout timing are included.
- Using rounded display values as exact downstream inputs for a contract or tax filing.
Interpretation and worked example
Run the bank's quoted principal, rate, term, and compounding frequency first. Then compare only one change, such as monthly versus quarterly compounding, to see whether the maturity difference is material.

FAQ
Which compounding frequency should I choose?
Use the frequency stated by the bank or product sheet. If the quote says quarterly compounding, choose quarterly; changing it to monthly will change both maturity value and EAR.
What is EAR and why show it?
Effective annual rate converts the nominal annual rate and compounding frequency into one yearly growth rate. It helps compare deposits with different compounding schedules.
Does this include tax or premature withdrawal rules?
No. The calculator reports gross maturity and interest before TDS, income tax, penalty interest, account fees, or product-specific payout rules.
Why can a bank quote differ from this result?
Differences usually come from compounding dates, day-count rules, rounding, payout timing, tax treatment, or whether the bank credits interest before maturity.
