About this Post Office calculator
Calculate the maturity of a Post Office 5-year recurring deposit: enter your monthly deposit and the current notified rate, and the calculator simulates the exact monthly-deposit, quarterly-compounding pattern India Post uses.
The Post Office RD rate is notified quarterly by the Ministry of Finance and locked for your account at opening — verify the current quarter on our small-savings rate table or indiapost.gov.in. This independent lemmatools calculator matches India Post’s published maturity figures for the same rate.
