Frequently Asked Questions
How is FD compound interest calculated?
Compound FD maturity is calculated using A = P(1 + r/n)^(nt), where P is principal, r is interest rate, n is compounding frequency, and t is tenure in years.
Does quarterly compounding yield more interest than annual compounding?
Yes! The more frequently interest compounds (e.g. quarterly vs annually), the higher your effective yield and overall maturity return.
