How to use this calculator

  1. Enter the amount you will deposit each month.
  2. Enter the annual interest rate.
  3. Enter the tenure in years.
  4. Read the maturity amount, total deposits and interest.

The formula

Each monthly deposit earns interest from the month it is made until maturity at a quarterly compounded rate. Maturity = Σ P × (1 + r ÷ 4)^((months remaining) ÷ 3), summed over every deposit. P is the monthly deposit and r is the annual rate as a decimal.

Worked example

Depositing ₹5,000 a month for 3 years (36 deposits) at 7% gives a maturity value of about ₹2,00,686. You deposit ₹1,80,000, so interest is about ₹20,686.

Understanding your result

Early deposits earn interest for longer than later ones, so the interest is not simply the rate times the total deposited. Missing a monthly instalment can lead to a penalty at most banks, which this tool does not model.

When to use it

  • Plan a fixed monthly saving for a goal with a known date.
  • Compare RD rates between banks and post offices.
  • Check what a small monthly habit becomes over a few years.

Assumptions and limits

Assumes deposits at the start of each month, a fixed rate and quarterly compounding. Banks may differ in compounding, day counts and rounding. Tax on interest is not included.

Frequently asked questions

How is an RD different from an FD?

An FD is one lump sum. An RD is a fixed amount deposited every month.

Is RD interest compounded quarterly?

For most Indian banks, yes. Check your bank's terms.

What if I miss a deposit?

Most banks charge a small penalty and some close the account after several misses.

Is the maturity amount guaranteed?

The rate is fixed at opening for the full tenure, subject to your bank's terms.

How is it different from a SIP?

An RD earns a fixed rate. A SIP in mutual funds has market-linked returns that are not guaranteed.
