Fixed Deposit & CD Calculator
Lock a deposit for a fixed term at a guaranteed rate and see exactly what it matures to. Known as a fixed deposit (FD) in South Asia, a Certificate of Deposit (CD) in the US, and a term deposit elsewhere — the safest, simplest way to grow cash.
Choose your country for local rates
Rates, currency and rules differ everywhere. Open the fixed deposit / CD calculator tuned to your country:
How maturity is calculated
Most fixed deposits compound quarterly: P × (1 + r/4)4n, where P is your deposit, r is the annual rate and n is the number of years. Monthly or annual compounding changes the result slightly. The calculator shows both your interest earned and the final maturity amount.
Safe — but watch inflation and tax
An FD/CD carries no market risk and is usually government-insured up to a limit. But two things quietly erode the return: inflation (if prices rise faster than your rate, your real gain is small) and tax (interest is normally taxed as income — a 30% bracket turns a 7% rate into roughly 4.9% after tax).
Best used for short-term certainty
Fixed deposits shine for money you will need in 1–5 years or for capital you cannot afford to lose. For long-term wealth, equities (see the SIP calculator) have historically outpaced FDs by a wide margin — at the cost of short-term volatility.
