RD Calculator – Recurring Deposit Maturity & Interest

RD Calculator – How Much Will Your Recurring Deposit Earn?

A recurring deposit (RD) lets you save a fixed amount every month and earn a guaranteed interest rate, just like a fixed deposit. It is one of the simplest ways to build a habit of saving – for a holiday, a gadget, school fees or an emergency fund. This free RD calculator works for Post Office RD and bank RDs such as SBI, HDFC Bank, ICICI Bank and others, and shows your maturity value, total interest and a year-wise statement.

RD interest rates in October 2026

The government kept the Post Office RD interest rate at 6.7% for the October–December 2026 quarter, announced on 30 September 2026. The rate is locked for the full five years when you open the account. Bank rates change more often, so always check your bank's latest rate card and use the preset buttons or type your own rate.

RD maturity formula

Banks and India Post compound RD interest quarterly. Each monthly instalment earns interest for the number of months it stays in the account, so the calculator adds up every instalment separately:

Maturity = Σ P × (1 + r/400)^{(months left ÷ 3)}

Here P is the monthly deposit and r the annual rate in percent. The first instalment earns interest for the full tenure, the last one for only one month. This is the same method used in the RD tables published by banks, so the result should match your passbook to within a few rupees.

RD maturity table: how much will you get?

So a ₹5,000 RD for 5 years in the Post Office gives about ₹3,56,829 – ₹56,829 more than you put in. A ₹100-a-month Post Office RD matures at about ₹7,137, which is how India Post quotes its rate tables.

Post Office RD Rules

• Minimum deposit ₹100 a month, in multiples of ₹10; no maximum.
• Tenure: 5 years (60 instalments), extendable once for another 5 years.
• Default fee: ₹1 for every ₹100 for each missed month; after four missed instalments the account is discontinued but can be revived within two months.
• Loan: after 12 instalments you can borrow up to 50% of the balance.
• Premature closure is allowed after 3 years, but you get only the Post Office savings account rate (4%).
• Advance deposit of 6 months or more earns a small rebate.

How Is RD Interest Taxed?

RD interest is fully taxable. It is added to your income and taxed at your slab rate, in the year it is earned, even though you receive it only at maturity. Banks deduct TDS at 10% when your total interest from that bank (FDs and RDs together) is more than ₹50,000 in a year, or ₹1 lakh for senior citizens. If your total income is below the taxable limit, submit Form 15G (or 15H if you are 60 or older) at the start of the year to avoid TDS. Post Office RD interest is not eligible for the 80C deduction.

RD vs FD vs SIP

An RD suits you when you have a monthly income and want guaranteed growth. If you already have a lump sum, an FD earns more because all the money is invested from day one – ₹3 lakh in a 5-year FD at 6.5% grows to about ₹4,14,126, while ₹5,000 a month for 5 years in an RD at the same rate gives ₹3,54,954. If your goal is more than 7 years away and you can handle ups and downs, an equity SIP has historically beaten both. Read our detailed RD vs FD comparison.
