Loading PaisaToolsMaturity on the current notified rate, what a missed instalment costs, and what the advance rebate is really worth
Reviewed by the PaisaTools Editorial Team · Last reviewed September 2026
How to use: Set your monthly instalment; the rate is already filled in for the current quarter. Then open the two panels below the result to price a missed instalment and the advance rebate.
Example₹5,000 a month for five years — what it matures at, what two missed instalments cost, and whether paying a year ahead is worth the rebate.
Minimum ₹100 in multiples of ₹10. There is no upper limit.
Set by the Ministry of Finance and revised every quarter. Pre-filled with the rate notified for Oct–Dec 2026.
The scheme runs 60 months. It can be extended in five-year blocks, which is why longer terms are allowed here.
Premature closure is allowed only after 3 years. Before that the money cannot be taken out, which is the part people discover too late.
Every calculator ranking for this query does the same one thing: maturity on an instalment and a rate. That part is not hard, and it is not where people actually get caught out. A recurring deposit is a five-year commitment, and the scheme has rules about what happens when life interrupts it — rules with specific numbers attached that no other calculator puts a figure on.
So this one does three things. It computes maturity on the rate notified for the current quarter, kept current rather than left to go stale. It prices a missed instalment — the fee, the deposit that never went in, the interest it would have earned, and the point at which the account is discontinued rather than merely penalised. And it prices the advance rebate honestly: not as free money, but annualised against the cash you gave up early, so it can be compared with the deposit rate on the same footing.
One thing worth saying plainly, because it is where the rate comparison misleads: the compounding here is no different from a bank RD. Both compound quarterly on the same formula. Anyone claiming the Post Office figure differs meaningfully on the arithmetic is selling a distinction that is worth a fraction of a percent. The real differences are the quarterly government reset, the fixed term, the default fee, and the three-year bar on closing early.
For a bank RD on a term you choose, use the general RD calculator. If the money is meant to stay untouched for much longer and tax-free matters more than access, PPF is the comparison to run instead — and the where-to-invest tool puts them side by side after tax and after inflation.
The interest rate is the one notified for Oct–Dec 2026in the Ministry of Finance's quarterly small-savings review, benchmarked to the five-year government security and revised every quarter. The minimum instalment, the sixty-month term, the default fee of ₹1 per ₹100 per missed month, discontinuation after 4 consecutive defaults with a 2-month revival window, the advance-deposit rebate tiers, and the bar on premature closure before 3 years are all set by the National Savings (Recurring Deposit) rules. The maturity formula was checked against a month-by-month simulation compounding each deposit quarterly over its own remaining term; the two agree to the rupee. Every statutory figure used here lives once in tax-config.ts, with the quarter it belongs to, rather than being repeated per page.
