Fixed Deposit / Compound Interest Calculator
Work out how a lump sum grows in a bank fixed deposit (or any compounding investment) over time -- enter the principal, annual rate, tenure, and compounding frequency (yearly, half-yearly, quarterly, or monthly), and see the maturity amount plus a full year-by-year balance breakdown.
This estimates gross interest only -- it doesn't account for TDS/withholding tax on the interest, or any premature-withdrawal penalty your bank may apply.

Frequently Asked Questions
How is compound interest calculated on a fixed deposit?
Maturity amount = Principal × (1 + rate/frequency)^(frequency × years). The calculator above applies this automatically for whichever compounding frequency you select.
Does this account for tax on FD interest?
No -- this shows gross interest only. Banks in Nepal typically deduct TDS (withholding tax) on interest income separately, which isn't reflected in this estimate.
What if I withdraw before maturity?
This calculator doesn't model premature-withdrawal penalties -- banks usually reduce the effective interest rate for an early withdrawal, so check your specific bank's terms.
Which compounding frequency should I choose?
Match whatever your bank's FD terms actually use -- quarterly compounding is common for fixed deposits in Nepal, but check your specific FD's terms.
Can I use this for a regular savings account instead of an FD?
Yes -- the compound-interest math is identical; just enter your savings account's own interest rate and compounding frequency.
