Post Office RD Calculator and Interest Rate (2026): 6.7% Explained

Post Office RD Calculator and Interest Rate (2026): 6.7% Explained

October 28, 2026

The Post Office Recurring Deposit (RD) lets you put away a fixed amount every month for five years and earn a government-set rate on it. For October to December 2026 that rate is 6.7% a year, compounded quarterly. Use the calculator above to see what your own monthly amount grows to. This page explains the rate, the rules and the traps that catch people out.

Post Office RD Interest Rate (October to December 2026)

The 5-year Post Office RD pays 6.7% a year for the October to December 2026 quarter, as set in the Finance Ministry’s notification of 30 September 2026. The rate is reviewed every quarter, and the next announcement, for January to March 2027, would normally come in the last week of December. The rate you get is fixed when you open the account. See all schemes side by side in our post office interest rates guide.

What Your Monthly Deposit Grows To

These figures use 6.7% compounded quarterly and 60 on-time monthly deposits. The calculator above gives the same results.

Monthly depositTotal deposited (5 years)Interest earnedMaturity value

₹1,000₹60,000₹11,366₹71,366
₹2,000₹1,20,000₹22,732₹1,42,732
₹3,000₹1,80,000₹34,097₹2,14,097
₹5,000₹3,00,000₹56,829₹3,56,829
₹10,000₹6,00,000₹1,13,658₹7,13,658

Interest works out to about 19% of what you deposit over the five years. That is more than 6.7% a year would suggest at first glance, because each deposit only earns interest for the time it is in the account, so early deposits earn the most. A ₹5,000 monthly RD ends with roughly ₹3.57 lakh, of which ₹56,829 is interest.

How the Post Office RD Works

The rules below come from the National Savings Recurring Deposit Scheme, 2019, published in the Gazette of India (G.S.R. 918(E), 12 December 2019). Rules can be amended, so confirm anything important at your post office.

  • Minimum deposit: ₹100 a month, in multiples of ₹10.
  • Tenure: five years, or 60 monthly deposits.
  • Compounding: quarterly.
  • Who can open one: a single adult, up to three adults jointly, a guardian on behalf of a minor, or a minor who is 10 or older in their own name. You can hold more than one account.
  • Due date: if the account is opened before the 16th of a month, each deposit is due by the 15th of every month. If it is opened from the 16th onwards, each deposit is due by the last working day of the month.
  • Same amount every month: the first deposit sets the denomination, and later deposits must equal it.

Closing Early: What You Actually Get

The scheme rules let you close the account early only after three years from the date of opening, by applying in Form-2. On early closure you are paid interest at the Post Office Savings Account rate, not the RD rate you booked. That rate is 4% for October to December 2026, so you give up a large part of the interest. If you have paid deposits in advance, you cannot close early until the period covered by those advance deposits is over. If there is a real chance you will need the money before three years are up, a different product may suit you better.

Borrowing Against Your RD

Once the account has run for at least one year and 12 monthly deposits have been made, you can take a loan of up to 50% of the deposits made in the account (the rule says deposits, not the balance including interest). The loan carries simple interest at 2 percentage points above the RD rate, which would be 8.7% at the current rate. You can repay it in one lump sum or in equal monthly instalments, and any unpaid amount is recovered from what you receive when the account closes. That is not cheap, so treat it as a last resort. The loan is not available if the account has been discontinued.

Missing a Deposit

The scheme rules treat a missed monthly deposit as a default, and they work like this:

  • Four or fewer defaults: you can choose to extend the maturity period by as many months as you missed, and pay the missed instalments during the extended period.
  • Revival fee: ₹1 for every ₹100 of the missed instalment, for each month of default, paid together with the lump-sum deposit of the missed instalments.
  • More than four defaults: the account is treated as discontinued. It can be revived only within two months of the month of the fourth default.
  • Discontinued and not revived: at maturity you are paid the amount for the deposits made, in proportion to the maturity table, not the full maturity value.

The safest habit is a standing instruction so the deposit never goes late.

Paying in Advance and Extending After 5 Years

Advance deposits. Once your account is running and not discontinued, you can pay six or more monthly instalments in advance, in any month. For an account of ₹100 a month, paying 6 to 11 instalments in advance earns a rebate of ₹10. Paying 12 or more earns ₹40 for every twelve instalments, plus ₹10 for any balance of six or more. For other amounts the rebate is proportionate. No rebate is given for fewer than six advance deposits.

After maturity you have two options. You can continue the account for up to five more years by making the same monthly deposit (Form-4). Or you can leave the maturity amount in the account for up to five more years without fresh deposits (Form-3). Either way, check the interest rate that will apply to the extended period at your post office before you choose, as the rules tie some of it to the Post Office Savings Account rate.

Tax on Post Office RD Interest

The interest you earn is part of your income and is taxed at your slab rate. Under section 393 of the Income-tax Act, 2025, which has applied since 1 April 2026, a post office deducts TDS only on interest from deposits under schemes the Central Government has notified for this purpose, and only when the interest credited or paid in a year exceeds ₹50,000 (₹1,00,000 for a senior citizen). Interest on deposits under certain other notified schemes is exempt from TDS under section 393(4). Whether or not any TDS is deducted, the interest is taxable and you must declare it in your return. For a government scheme with a tax deduction on the principal, see our Post Office TD calculator, which covers the 5-year Time Deposit.

Is a Post Office RD the Right Choice?

  • It suits you if you want a fixed, government-backed return and can commit to a set amount every month for five years.
  • It suits you less if you might need the money in the first three years, or want a higher return and can accept market risk. In that case compare it with a small SIP.
  • Compare before you open: bank recurring deposits can differ from the post office. Our general RD calculator and FD rates guide help you check.
