Calculate the maturity value of a fixed deposit by entering the principal, annual interest rate, tenure, and compounding frequency. See how much interest your FD will earn over the full term.
A fixed deposit locks your principal for a set tenure at a guaranteed interest rate. Interest compounds at the chosen frequency (quarterly is most common for bank FDs), and the full maturity amount is paid at the end of the term.
FDs are one of the safest investment options, backed by deposit insurance (up to applicable limits) in most jurisdictions.
Standard compound interest formula.
Maturity = P × (1 + r/n)^(n×t)
P = principal, r = annual rate, n = compounding frequency per year, t = tenure in years.
Assumes the rate is fixed for the entire tenure (variable-rate FDs exist but are uncommon). Does not account for TDS (tax deducted at source) on interest income. Premature withdrawal penalties are not modelled.
Frequently asked questions
Yes. More frequent compounding (monthly vs quarterly vs annual) produces a slightly higher maturity amount due to more frequent interest-on-interest. The difference is modest for typical FD rates but grows with longer tenures.
The effective rate accounts for compounding. A 7% nominal rate compounded quarterly has an effective rate of about 7.19%. The calculator shows this for easy comparison across products.
In most jurisdictions, yes. In India, TDS is deducted if annual interest exceeds a threshold. In the US and UK, interest income is taxed as ordinary income. This calculator shows pre-tax maturity.
Most banks charge a penalty (typically 0.5–1% reduction in rate) for premature withdrawal. Some FDs do not allow early withdrawal at all. Check your bank’s terms.
