ReckonBoxHow the EPF calculator works
An EPF calculator projects the Employees Provident Fund corpus you will have at retirement, from your monthly basic salary, the 12% you and your employer each pay, an assumed salary growth, and the EPF interest rate. The Employees Provident Fund is a salary-linked, employer-matched retirement scheme, and it pays 8.25% for FY 2025-26, declared by the EPFO each year. Give the calculator your salary and it builds the balance year by year to age 58.
On the default numbers, the compounding does most of the work. A 30-year-old with a Rs 25,000 basic growing 5% a year reaches about Rs 1.06 crore in EPF by 58, of which roughly Rs 68 lakh is interest on Rs 37.85 lakh contributed. The tool splits the employer share correctly, keeps the pension part separate, and takes an existing balance so you can project the account you already have.
How the EPF contribution splits
You contribute 12% of your basic salary plus dearness allowance, and your employer contributes another 12%, but 8.33% of the employer share is diverted to the pension scheme (EPS) and capped at a Rs 15,000 wage. That cap is the detail most calculators miss. Because 8.33% applies only up to Rs 15,000, at most Rs 1,250 a month leaves for EPS, and everything above that stays in your EPF.
The effect grows with salary. At a Rs 25,000 basic, you put in Rs 3,000 and your employer adds Rs 1,750 to EPF (its 12%, which is Rs 3,000, minus the Rs 1,250 that goes to EPS), for Rs 4,750 a month into the fund. A calculator that uses the popular flat "15.67% of basic" shortcut would show only Rs 3,918, because it wrongly sends 8.33% of your whole salary to EPS. The gap widens higher up: at a Rs 50,000 basic, Rs 4,750 of the employer share stays in EPF while still only Rs 1,250 goes to EPS.
| Monthly basic | Your 12% | Employer to EPF | Employer to EPS |
|---|---|---|---|
| Rs 12,000 | Rs 1,440 | Rs 440 | Rs 1,000 |
| Rs 25,000 | Rs 3,000 | Rs 1,750 | Rs 1,250 (capped) |
| Rs 50,000 | Rs 6,000 | Rs 4,750 | Rs 1,250 (capped) |
How EPF interest is calculated
EPF interest is calculated on the monthly running balance, using the balance at the start of each month, and credited once a year on 31 March. The rate for FY 2025-26 is 8.25% a year, which the EPFO Central Board of Trustees set at its March 2026 meeting, the same rate as the previous two years.
Because interest runs on the running balance, a contribution starts earning only from the following month, so the money you add during a year earns less than a full year of interest. That is why the first year on a fresh account earns modestly: on the default salary, year one adds about Rs 57,000 of contributions but only about Rs 2,155 of interest. By the final working year the balance itself is throwing off far more interest than the fresh contributions, which is compounding taking over.
A year-by-year worked example
Follow the default Rs 25,000 basic from age 30 to 58 at 5% salary growth. Each year the salary rises, so the contributions rise with it, and the interest builds on a bigger base.
| Year | You | Employer to EPF | Balance |
|---|---|---|---|
| 1 | Rs 36,000 | Rs 21,000 | Rs 59,155 |
| 14 | Rs 67,884 | Rs 52,884 | Rs 20,39,349 |
| 28 | Rs 1,34,400 | Rs 1,19,400 | Rs 1,06,00,836 |
By the last year, the yearly interest alone is about Rs 8 lakh, more than three times the year's contributions. The full 28-row table in the tool shows every year, and it updates as you change the salary, the growth rate, or the interest rate.
The EPS pension part
The 8.33% diverted to the Employees Pension Scheme earns no interest and does not build a balance you withdraw; it funds a defined monthly pension after retirement. This is why the calculator keeps EPS out of the EPF corpus and reports it as a separate line. On any salary above Rs 15,000, exactly Rs 1,250 a month goes to EPS, which over a 28-year career is Rs 4.2 lakh of contributions that fund a pension you draw monthly.
The pension itself follows a separate formula based on your pensionable salary and years of service, so the EPS line here shows the contribution, while the monthly pension is a different figure. Sizing that pension is its own calculation, separate from the corpus this tool projects.
Is EPF taxed
Your EPF contribution qualifies for a Section 80C deduction of up to Rs 1.5 lakh a year, the same limit that covers PPF and ELSS together. The interest is tax-free, but only on an employee contribution up to Rs 2.5 lakh a year: interest on any contribution above that threshold, introduced in the 2021 Budget, is taxable in your hands. The maturity amount is tax-free once you have completed 5 years of continuous service, so a withdrawal before that can attract tax.
EPF or PPF
Both EPF and PPF are government-backed retirement funds with an 80C benefit, but they work differently, and most salaried people hold both.
| Feature | EPF | PPF |
|---|---|---|
| Who funds it | You and your employer | You alone |
| Rate | 8.25%, declared yearly by EPFO | 7.1%, set quarterly |
| Contribution | 12% of basic, employer matches | Rs 500 to Rs 1.5 lakh a year |
| Access | At retirement or on leaving a job | 15-year lock-in |
| Best for | Salaried employees automatically | Anyone, including the self-employed |
EPF is tied to your job and your employer's match, so it builds fastest while you are employed; the PPF calculator covers the self-funded route that anyone can open. To size the total lump sum your retirement needs across all sources, the retirement corpus calculator works backward from your expenses.
What this does not promise
The 8.25% rate is declared once a year and can change, so a projection to age 58 at today's rate is a planning estimate that shifts as the rate moves. The salary growth you enter is an assumption too, and real increments are uneven, so treat the corpus as an illustration that you refresh as your salary and the rate move. EPF rules and rates are set by the government and the EPFO, and this is not investment advice, so a SEBI-registered adviser can weigh EPF against your wider plan. The calculator projects the balance to retirement and does not model early or partial withdrawals.
Frequently asked questions
What is an EPF calculator? An EPF calculator estimates the Employees Provident Fund corpus you will have at retirement from your monthly basic salary, the contribution rate, an assumed salary growth, and the EPF interest rate. It splits the employer contribution correctly, keeps the pension (EPS) part separate, and shows the year-by-year build.
How is EPF contribution calculated? You contribute 12% of your basic salary plus dearness allowance, and your employer contributes another 12%. Of the employer 12%, 8.33% goes to the pension scheme (EPS) but is capped at a Rs 15,000 wage, so at most Rs 1,250 a month leaves for EPS and the rest stays in your EPF. On a Rs 25,000 basic, that is Rs 3,000 from you plus Rs 1,750 from your employer into EPF each month.
What is the current EPF interest rate? The EPF interest rate is 8.25% per annum for FY 2025-26, the same rate as the previous two years, declared by the EPFO Central Board of Trustees. Interest is calculated on the monthly running balance and credited once a year on 31 March.
Why is my EPF corpus higher than a flat 15.67% of salary suggests? Because the 8.33% pension diversion is capped at Rs 1,250 a month, not 8.33% of your whole salary. Above a Rs 15,000 basic, more of the employer 12% stays in EPF. At a Rs 25,000 basic, Rs 4,750 a month goes to EPF, not the Rs 3,918 that a flat 15.67% shortcut gives, so calculators using that shortcut understate your corpus.
Does the EPS pension part earn interest? No. The 8.33% diverted to the Employees Pension Scheme earns no interest and does not build a balance you withdraw. It funds a defined monthly pension after retirement instead, which is why this calculator keeps it out of the EPF corpus and shows it separately.
How is EPF interest calculated? EPF interest is calculated on the monthly running balance, using the balance at the start of each month, then credited once a year on 31 March. A contribution starts earning interest from the following month, so the money you add during a year earns less than a full year of interest.
Is EPF taxed? Your EPF contribution qualifies for a Section 80C deduction up to Rs 1.5 lakh. The interest is tax-free only on an employee contribution up to Rs 2.5 lakh a year, and interest on any excess is taxable. The maturity amount is tax-free if you have completed 5 years of continuous service.
Can I contribute more than 12% to EPF? Yes, through a voluntary provident fund (VPF) you can raise your own contribution above 12%, up to 100% of basic plus DA, and it earns the same EPF interest. Your employer's share stays at 12%. Increase the contribution percentage in this calculator to see the effect of a VPF top-up.
When can I withdraw my EPF? The full EPF balance is normally withdrawn at retirement, treated as age 58 here, or after two months of unemployment. Partial advances are allowed for specific needs like a house, medical treatment, or education, subject to EPFO conditions. This calculator projects the balance to retirement rather than modelling early withdrawals.
