FD formula
A cumulative fixed deposit uses compound interest:
M = P × (1 + r/n)n×t
where P is the principal, r is the annual rate (as a decimal), n is the number of compounding periods per year, and t is the term in years.
Why compounding frequency matters
The more often interest is compounded, the sooner earned interest starts earning its own interest. For the same rate, quarterly compounding yields slightly more than annual compounding. Confirm the frequency your bank uses for your specific deposit.
