About the SCSS Calculator
The SCSS Calculator computes the maturity value of your Public Provident Fund, Fixed Deposit, RD, NSC, SCSS or KVP — all of which use government-fixed or bank-set interest rates with deterministic compounding. These are the workhorses of the Indian risk-averse investor: backed by sovereign guarantee (in the case of small savings) or DICGC insurance up to ₹5L (for bank deposits), they're where the bulk of household savings sits.
How the SCSS Calculator works
- Enter your principal (lumpsum or annual contribution), the prevailing interest rate and the lock-in period.
- The calculator compounds at the frequency specified by the scheme (annual for PPF/NSC, quarterly for FD/SCSS, monthly for MIS).
- It shows year-by-year interest accrual so you can visualise the late-stage compounding bump.
- For PPF, it also models the partial withdrawal rules from year 7 and the 5-year extensions post maturity.
Inputs explained
Formula
A = P × (1 + r/m)^(mt) where P = principal, r = annual rate, m = compounding periods/year, t = years. For recurring contributions: sum each year's contribution × (1 + r)^(remaining years).
Worked example
A ₹1.5L annual PPF contribution at 7.1% for 15 years matures at roughly ₹40.7L — of which ₹22.5L is your contribution and ₹18.2L is tax-free interest under EEE (Exempt-Exempt-Exempt) status.
India-specific notes
- •PPF, EPF, SSY and SCSS interest is fully tax-free at maturity (EEE category).
- •FD interest is fully taxable at your slab rate; banks deduct 10% TDS if interest exceeds ₹40k/year (₹50k for seniors).
- •Small-savings rates are revised every quarter by the Ministry of Finance — your accrued balance keeps the rate of the period it was earned in.
- •PPF allows partial withdrawals from year 7 onward — useful as a tax-free emergency reserve.
Tips to maximise this calculator
- →Contribute to PPF before the 5th of every month — interest is calculated on the minimum balance between 5th and end-of-month.
- →Ladder your FDs across 1, 2, 3 and 5 year buckets to balance liquidity and rate risk.
- →Use SCSS for parents — guaranteed 8.2% with quarterly payout, ideal for retirement income.
Common mistakes to avoid
- ✕Putting emergency money in PPF (locked for 7 years before first withdrawal).
- ✕Forgetting to declare FD interest in ITR — banks report it via AIS regardless of TDS.
- ✕Locking long-tenure FDs when rates are about to rise — ladder instead.
