Savings Calculators

Project maturity values for PPF, EPF, NPS, fixed and recurring deposits, and Sukanya Samriddhi, down to the exact month interest is credited.

6 calculators

Government-backed savings schemes look simple on the surface (a fixed rate, a lock-in period), but the details of how and when interest actually compounds can change your maturity value more than most people expect. These calculators model the real mechanics: monthly-computed but annually-credited interest, contribution ceilings, and lock-in rules specific to each scheme.

How to think about savings calculators

A few principles worth knowing before you run the numbers.

1Lock-in periods vary enormously

PPF locks in for 15 years, EPF until retirement, Sukanya Samriddhi for 21 years from account opening, while a Fixed Deposit can run as short as 7 days. Match the scheme to how soon you might actually need the money, not just its interest rate.

2Interest crediting timing matters more than people think

Several of these schemes compute interest every month but credit it to your balance only once a year, so a lump sum deposited early in the financial year earns noticeably more than the same amount spread across monthly instalments.

3Government-backed doesn't mean identical

PPF, EPF and NPS all carry a sovereign guarantee, but with very different contribution rules, withdrawal flexibility and tax treatment on exit. The right mix depends on your employment status and how soon you need the money, not just the headline rate.

4A recurring deposit isn't the same math as a fixed deposit

An RD's maturity value uses a quarterly-compounding formula built around monthly instalments, not a single lump sum growing at a fixed rate. The RD Calculator uses the actual bank formula, not an approximation.

Frequently asked questions

Straight answers to the questions we hear most about Savings calculators.

Which is better, PPF or EPF?
EPF is built around salaried employment: both you and your employer contribute automatically every month. PPF is open to anyone and offers more contribution flexibility, but with no employer match. Many salaried savers use both.
Are these schemes' interest rates fixed for the full tenure?
No, PPF, EPF, NPS, and Sukanya Samriddhi rates are reviewed and can change quarterly (or annually for EPF) by the government. Bank Fixed and Recurring Deposit rates are locked in at the time you open the account, for that account's tenure.
Can I withdraw before the lock-in ends?
Most of these schemes allow partial withdrawals after a minimum number of years (PPF from year 7, Sukanya Samriddhi once the girl turns 18), but the full balance typically stays locked until maturity. Check each calculator's assumptions for the specific rule.
Is the interest from these schemes taxable?
PPF and Sukanya Samriddhi are fully tax-exempt (EEE status) on contribution, interest, and maturity. EPF and NPS have their own partial exemptions on withdrawal. Fixed and Recurring Deposit interest is fully taxable at your slab rate, with TDS withheld above a threshold.
What's the difference between a Fixed Deposit and a Recurring Deposit?
A Fixed Deposit is a single lump sum invested at once; a Recurring Deposit builds up through fixed monthly instalments. Both earn compound interest, but the underlying maturity formula is different. See the FD and RD calculators for each.
Why does Sukanya Samriddhi have two different time periods?
Deposits are only accepted for 15 years from account opening, but the account itself matures 21 years after opening. The balance keeps earning interest for the years in between with no further contributions required.
