What is Post Office RD Calculator India?
▾
The Post Office Recurring Deposit (PORD) is a government-backed monthly savings scheme available at all post offices in India. It allows individuals to deposit a fixed amount every month for 5 years and earn interest compounded quarterly. The current interest rate for FY 2024-25 is 6.7% per annum, compounded quarterly. The minimum deposit is ₹100 per month (in multiples of ₹10), and there is no upper limit on the monthly deposit. Unlike bank RDs which offer competitive rates that may change more frequently, Post Office RD rates are set quarterly by the government alongside other small savings scheme rates. Interest is compounded quarterly and accumulated; the maturity amount includes all monthly contributions plus compounded interest. An important distinction: Section 80C deduction is NOT available for Post Office RD contributions (unlike PPF, NSC, SCSS, 5-year Post Office Time Deposit, and Sukanya Samriddhi). The interest earned is taxable as 'Income from Other Sources' at the applicable slab rate. TDS is deducted if interest exceeds ₹40,000 per year (₹50,000 for senior citizens). The RD can be premature closed after 3 years (penalty: interest reduced to Post Office savings account rate for the premature period). A loan of up to 50% of the deposited amount can be taken after 12 instalments. Post Office RD is ideal for disciplined monthly savers who prefer government-guaranteed returns and want to build a corpus over 5 years without the complexity of market-linked products.

Worked Examples
▾
Interest is taxable at slab rate; no Section 80C deduction on RD contributions
Total deposited = 5,000 × 60 = ₹3,00,000. At 6.7% quarterly compounding, the maturity value is approximately ₹3,55,800. Interest earned ≈ ₹55,800, taxable as income from other sources.
Ideal for children's savings accounts and low-income households
Even at ₹100/month, the disciplined saving builds ₹7,116 over 5 years — a 18.6% absolute return. Good for teaching children the habit of saving through their first post office RD account.
Bank RD at higher rate outperforms PORD; but bank rates vary and PORD has sovereign guarantee
At 0.3% higher rate, bank RD generates approximately ₹12,000 more over 5 years. However, Post Office RD benefits from sovereign guarantee (government-backed) and is not subject to DICGC insurance limits unlike bank deposits.
Premature closure allowed after 3 years; interest recalculated at savings account rate
On premature closure after completing 3 years, the Post Office recomputes interest at the savings account rate (4%) instead of the contracted 6.7% RD rate. The difference of ₹3,900 is the effective penalty on premature closure.

NRI and Post Office RD
{'title': 'NRI and Post Office RD', 'body': 'Non-Resident Indians (NRIs) cannot open new Post Office small savings accounts including RDs. However, if an account was opened before becoming an NRI, it can be continued until maturity at the contracted rate. On maturity, the proceeds can be repatriated subject to FEMA regulations.'}
Post Office RD for Children — Education Saving
{'title': 'Post Office RD for Children — Education Saving', 'body': 'Opening a Post Office RD for a child can serve as a simple, safe education savings tool. ₹5,000/month for 5 years yields approximately ₹3.55 lakh — useful as a contribution toward school fees, coaching costs, or early college expenses. For longer-term goals (graduation in 15 years), Sukanya Samriddhi (for girl children) or mutual fund SIPs offer better returns.'}
Multiple RD Accounts
{'title': 'Multiple RD Accounts', 'body': 'An individual can open multiple Post Office RD accounts across different post offices. Each account has its own monthly deposit and tenure. There is no aggregate limit. This allows systematic savings towards different goals simultaneously. However, all RD interest from all accounts is aggregated for TDS threshold calculation.'}
Extension After Maturity
At maturity, you must either withdraw the amount or open a fresh RD. If no instructions are given on maturity, the balance earns interest at the Post Office savings account rate. For continuous monthly saving, open a fresh RD immediately on or before maturity.'}

Frequently Asked Questions
▾
What is a Post Office Recurring Deposit and how does it work?
A Post Office Recurring Deposit (RD) is a government-backed savings scheme in India where you deposit a fixed amount monthly for a chosen tenure (1-5 years). Interest rate: set quarterly by the Government of India (currently around 6.7% per annum, compounded quarterly). Maturity value formula: M = R × [(1+i)ⁿ - 1] / [1-(1+i)^(-1/3)], where R = monthly deposit, i = quarterly interest rate, n = number of quarters. Example: ₹5,000/month for 5 years at 6.7%: total deposits = ₹3,00,000, interest earned ≈ ₹55,000, maturity value ≈ ₹3,55,000. Minimum deposit: ₹100/month with no maximum limit. Available at any India Post office. One of the safest investment options as it's backed by the Government of India with sovereign guarantee.
How does Post Office RD compare to bank recurring deposits?
Interest rate: Post Office RD rates are generally competitive with or slightly higher than bank RD rates for similar tenures, as they follow government-set rates revised quarterly. Safety: Post Office RD has sovereign guarantee (government-backed), while bank RDs are insured only up to ₹5 lakh by DICGC. Tax treatment: interest is fully taxable as 'Income from Other Sources' for both; however, Post Office doesn't deduct TDS (tax deducted at source) on interest, while banks deduct TDS if annual interest exceeds ₹40,000 (₹50,000 for seniors). Flexibility: banks often offer more tenure options and easier online management. Post Office allows one missed payment (with penalty) before default, and premature withdrawal after 3 years with penalty. Loan facility: you can borrow up to 50% of the balance after 12 monthly deposits. For most conservative investors prioritizing safety over returns, the Post Office RD is an excellent choice, especially for amounts exceeding the ₹5 lakh bank deposit insurance limit.
How is the interest on a Post Office RD calculated, and what is the maturity amount?
Interest on a Post Office RD is compounded quarterly based on the current annual rate of 6.7% for FY 2024-25. This means the interest earned in each quarter is added to the principal for subsequent interest calculations. For instance, a monthly deposit of ₹1,000 over 5 years (60 months) at this rate would accumulate a total of ₹60,000 in deposits, yielding a maturity value of approximately ₹67,900, including the compounded interest.
What are the consequences of missing an installment or making a premature withdrawal from a Post Office RD?
Missing a monthly installment incurs a penalty of ₹1 for every ₹100 of the installment amount; for example, a ₹500 missed payment results in a ₹5 penalty. If four consecutive installments are missed, the account becomes discontinued but can be revived within two months by clearing all arrears and penalties. Premature withdrawal is allowed after one year, but the interest rate for the period held will be reduced to that of a Post Office Savings Account (currently 4% per annum).
Can a Post Office RD account be extended beyond its initial 5-year term?
Yes, a Post Office RD account can be extended for an additional 5 years after its initial 5-year maturity. To extend, the account holder must submit a request at their respective Post Office. The interest rate applied during the extended period will be the prevailing rate at the time of extension, and interest continues to be compounded quarterly.
Common Mistakes to Avoid
▾
- !Confusing Post Office RD with Post Office 5-Year Time Deposit — only the Time Deposit (FD) qualifies for Section 80C; the RD does not.
- !Not reporting RD interest in ITR — interest accrued each year on Post Office RD is taxable even before maturity; failure to report constitutes a tax compliance error.
- !Missing instalments without paying penalties — missing 4 consecutive instalments discontinues the account; the penalties and revival process are cumbersome.
- !Expecting Post Office RD interest rates to remain fixed for 5 years — rates are reviewed quarterly and can change during the RD tenure; only the rate at opening is locked for that quarter, and subsequent quarters get the prevailing rate.
- !Not considering inflation-adjusted returns — at 6.7% gross return, post-tax return for a 30% bracket investor is only 4.7%; this barely keeps pace with India's average inflation.
- !Choosing RD over PPF for medium-to-long term goals — PPF at 7.1% (EEE tax status) vastly outperforms RD at 6.7% on a post-tax basis for any investor with taxable income.
Pro Tip
Use Post Office RD for short-term (5-year), goal-specific savings where you want government-guaranteed returns and disciplined monthly deposit habits. For tax efficiency and better returns, combine with PPF (for long-term) and equity mutual fund SIPs (for growth). Never use RD as your primary retirement savings vehicle.
