📘 About the Post Office RD Calculator

A Post Office Recurring Deposit is a 5-year savings plan in which you deposit a fixed amount every month. Interest is compounded quarterly and the account matures after 60 monthly deposits.

Enter your monthly deposit and the current interest rate to see the maturity amount, your total deposits and the interest earned.

🧮 Formula

Where

  • P = monthly deposit
