RD Calculator
See how much your monthly deposits grow over time, and how much of the final amount is interest.
How an RD grows
An RD lets you put the same amount in every month for a fixed time. Each deposit earns interest from the day it goes in. Earlier deposits earn interest for longer, so the final amount is more than just all your deposits added together.
Banks usually add interest every three months, but this calculator assumes monthly for simplicity—treat the result as a close estimate. If you have a lump sum instead of monthly deposits, check our FD calculator.
Common questions
What's the difference between an RD and an FD?
An FD is a one-time deposit that you lock in. An RD lets you add the same amount every month. RDs are good for regular savers; FDs work if you already have a lump sum.
Do I pay tax on RD interest?
Yes. RD interest is added to your income and taxed at your tax rate. If the interest crosses a certain amount, the bank deducts tax automatically. This calculator shows the amount before tax.
What happens if I skip a deposit?
Missing a deposit usually means a small penalty and a lower final amount, since that month's deposit won't earn interest. This calculator assumes you deposit every month on time.
