What is a Fixed Deposit?
A Fixed Deposit (FD) is a savings product where a lump sum is deposited for a fixed term at a fixed interest rate, with interest typically compounding at a set frequency until maturity.
The formula
Maturity Value = P × (1 + r/n)n×t, where P is the principal, r is the annual rate, n is the compounding frequency per year, and t is the term in years.
This calculator is for general savings-planning education; actual FD terms, penalties for early withdrawal, and tax treatment vary by institution and country.
