How Does an FD Interest Calculator Work?
The calculator uses the compound interest formula to estimate your maturity value based on the details you provide.
Compound Interest Formula
A = P(1 + r/n)^(nt)
Formula Explanation

P = Principal Investment Amount
r = Annual Interest Rate
n = Number of Compounding Periods Per Year
t = Investment Tenure in Years
The formula calculates how your money grows over time when interest is added periodically.
