About the Post Office RD Calculator

The Post Office Recurring Deposit, officially called the National Savings Recurring Deposit, is a government backed 5 year scheme with a fixed rate decided by the Ministry of Finance each quarter. You deposit a fixed amount monthly, and the account can be extended with interest benefits after maturity. Use this Post Office RD calculator to estimate your 5 year maturity value.

What is an RD Calculator?

A recurring deposit calculator estimates the maturity value of fixed monthly deposits held for a chosen tenure. Since each monthly installment earns interest for a different duration, the calculation involves a series of compounding terms rather than a single formula step, which is exactly what the calculator handles for you.

How Does the Post Office RD Calculator Work?

Banks compound recurring deposit interest quarterly, and the standard maturity formula is:

M = R x [(1 + i)^n – 1] / (1 – (1 + i)^(-1/3))

M is the maturity value.
R is the monthly installment.
i is the quarterly interest rate, taken as the annual rate divided by 4.
n is the total number of quarters in the tenure.

Example

Saving Rs. 5,000 every month for 5 years at an assumed 6.7% per year compounded quarterly gives a maturity value of about Rs. 3,56,829, against total deposits of Rs. 3,00,000. The difference is your interest income.

Projected growth at Rs. 5,000 per month and 6.7% expected rate

Frequently Asked Questions

What is the current Post Office RD rate and tenure?

The National Savings RD runs for 5 years at a government notified rate, which recently stood at 6.7% per year, revised quarterly. Each deposit must be made by the same date monthly, and up to 4 defaults can be regularised.

What return rate should I enter in the Post Office RD Calculator?

Enter the RD rate the bank quotes for your tenure, which you can check on the official website. In this illustration 6.7% per year is assumed, and senior citizens usually get about 0.5% more.

Is RD interest taxable?

Yes. RD interest is taxed at your income slab rate, and TDS applies once annual interest crosses the prevailing threshold. Unlike a 5 year tax saver FD, RDs do not qualify for Section 80C.

Should I choose an RD or an SIP instead?

An RD gives fixed, predictable returns at deposit rates, while a market linked SIP can deliver higher long term growth with volatility. Conservative savers prefer RDs, and long term investors often hold both.
