Post Office Savings Calculator — Compare All Government Schemes — India 2026

Fixed Deposit Calculator

Understanding Your Investment Returns

This calculator projects your returns using compound interest, where your earnings generate their own earnings over time. The power of compounding means that even small regular investments can grow into substantial wealth over long periods. For example, investing just Rs 5,000 per month at 12% expected returns for 25 years can grow to over Rs 1 crore — of which only Rs 15 lakh is your own money and Rs 85 lakh is compounding returns. The key factors that determine your final corpus are: the amount invested, the rate of return, the duration of investment, and the frequency of compounding.

Important Considerations

Past returns do not guarantee future performance, especially for market-linked instruments like mutual funds and equities. The returns shown are estimates based on the rate you enter. Equity investments carry market risk but have historically delivered 12-15% CAGR over 15+ year periods in India. Fixed income options like PPF (7.1%) and FD (6-7.5%) offer lower but more predictable returns. Diversifying across asset classes — equity, debt, gold, and real estate — reduces overall portfolio risk while optimizing returns for your risk tolerance.

India Post Small Savings Rates — July–September 2026 Quarter

Small savings interest rates are notified quarterly by the Ministry of Finance (Department of Economic Affairs), which pegs each scheme to government-security yields under the Shyamala Gopinath committee formula. The figures below apply to the July–September 2026 quarter — rates were held unchanged in the 30 June 2026 notification for Q2 FY 2026-27. The next reset lands on 1 October, so verify the current notification on the National Savings Institute or India Post website before locking money in. Post Office Savings Account (SB): 4.0% per year. Time Deposits: roughly 6.9% for 1 year, 7.0% for 2 years, 7.1% for 3 years and 7.5% for 5 years, compounded quarterly and paid annually. 5-Year Recurring Deposit (RD): 6.7%. Monthly Income Scheme (MIS): 7.4%, paid monthly. Senior Citizens Savings Scheme (SCSS): 8.2%, paid quarterly. National Savings Certificate (NSC): 7.7%, compounded annually for 5 years. Public Provident Fund (PPF): 7.1%, compounded annually. Kisan Vikas Patra (KVP): 7.5%, doubling your money in 115 months (9 years 7 months). Sukanya Samriddhi Yojana (SSY): 8.2%. A useful anchor: Rs 1,00,000 in a 5-year Time Deposit at 7.5% grows to about Rs 1,44,995, while the same amount in NSC at 7.7% matures at about Rs 1,44,903 — nearly identical outcomes, but their tax treatment differs sharply, which is where scheme choice really matters.

Which Post Office Scheme Fits Which Goal

Regular income for seniors: SCSS is the flagship — 8.2% with quarterly payouts, a Rs 30 lakh ceiling per individual, entry at age 60 (55 for VRS retirees, 50 for retired defence personnel). A maxed-out Rs 30 lakh earns Rs 61,500 every quarter. Pair it with MIS, which pays monthly: the Rs 9 lakh single-account cap yields Rs 5,550 a month, and a Rs 15 lakh joint account Rs 9,250. Girl child's education and marriage: SSY at 8.2% is the highest small-savings rate on offer — deposits of Rs 250 to Rs 1.5 lakh a year for a daughter under 10; the account matures 21 years after opening (deposits are required only for the first 15 years), with partial withdrawal for education allowed once she turns 18. Tax saving under Section 80C: PPF (7.1%, fully tax-free), NSC (7.7%) and the 5-year Time Deposit (7.5%) all qualify, up to Rs 1.5 lakh a year. Disciplined monthly saving: the 5-year RD at 6.7% — Rs 5,000 a month builds roughly Rs 3.56 lakh at maturity. Guaranteed doubling with no ceiling: KVP doubles money in 115 months at 7.5%, with no upper investment limit. Liquidity: the savings account (4.0%) and 1-year TD (about 6.9%) keep funds accessible. Every rupee is sovereign-backed — there is no DICGC-style Rs 5 lakh cap, because the guarantee is the Government of India itself, across all 1.55 lakh post office branches.

Tax and TDS Treatment, Scheme by Scheme

Tax treatment separates otherwise similar rates. PPF and SSY are the only fully EEE schemes: the deposit qualifies for Section 80C (old regime), and both interest and maturity are entirely tax-free — Rs 1.5 lakh a year in PPF for 15 years at 7.1% builds roughly Rs 40.7 lakh with zero tax. NSC interest is taxable at slab, but interest accrued in years 1–4 is deemed reinvested and can itself be claimed under 80C; there is no TDS on NSC. SCSS interest is fully taxable, and TDS applies once interest crosses the senior-citizen threshold — raised to Rs 1 lakh per financial year from April 2025 (Budget 2025); a maxed-out Rs 30 lakh SCSS earning Rs 2,46,000 a year will see TDS unless Form 15H is filed. MIS, KVP, RD and Time Deposit interest is taxable at your slab rate; the post office generally does not deduct TDS on these, but the income must still be declared in your ITR. The 5-year TD is the only deposit variant with an 80C benefit. Savings-account interest gets a special Section 10(15)(i) exemption of Rs 3,500 (Rs 7,000 for joint accounts), on top of the Rs 10,000 deduction under 80TTA — Rs 50,000 under 80TTB for seniors — in the old regime. Under the new regime none of these deductions apply, though PPF and SSY maturities stay tax-free.

Dedicated Calculators for Each Scheme

This page is the hub — each scheme has its own calculator with year-by-year tables. For 5-year certificates, the [NSC calculator](/nsc-calculator) compounds at 7.7% annually and shows the 80C-eligible accrued interest for each year. The [KVP calculator](/kvp-calculator) works out the 115-month doubling and intermediate encashment values. The [PPF calculator](/ppf-calculator) projects the 15-year, 7.1% ladder (see also the [PPF interest rate history](/ppf-interest-rate-history) for how the floating rate has moved). Monthly savers can model the 6.7% RD on the [RD calculator](/rd-calculator), and parents can project SSY maturity at 8.2% on the [Sukanya Samriddhi calculator](/sukanya-samriddhi-calculator). To weigh post office Time Deposits against bank FDs, use the [FD calculator](/fd-calculator); retirees comparing SCSS with bank rates should check the [senior citizen FD calculator](/senior-citizen-fd-calculator) and the [FD monthly interest calculator](/fd-interest-calculator-monthly) for income planning. A practical workflow: shortlist two or three schemes from the rate table above, run each through its dedicated calculator with the same amount and horizon, then apply the tax rules from the previous section to compare post-tax maturity values — at the 30% slab a taxable 7.5% becomes roughly 5.25%, which is why tax-free PPF at 7.1% often wins over long horizons.
