FD & RD Calculator
Calculate the maturity value and interest earned on a fixed deposit (FD) or recurring deposit (RD), with selectable compounding frequency.
About the FD & RD Calculator
A fixed deposit invests a lump sum that compounds at a chosen frequency: maturity = P × (1 + r/n)^(n·t). A recurring deposit invests a fixed amount every month; its maturity is the future value of those monthly installments. Use the toggle to switch between the two and compare how compounding frequency and tenure affect the final amount.
Frequently asked questions
- How is FD maturity calculated?
- Fixed-deposit maturity uses compound interest: M = P × (1 + r/n)^(n·t), where P is the deposit, r the annual rate, n the number of compounding periods per year, and t the tenure in years. More frequent compounding yields slightly higher returns.
- How does an RD differ from an FD?
- A fixed deposit is a single lump sum locked for the tenure, while a recurring deposit adds a fixed amount every month. RD maturity is the accumulated future value of all monthly installments plus interest.
