Compound Interest Calculator
See compounding at work — principal, rate, tenure and compounding frequency in, maturity value and total interest out, with year-wise growth.
Year-wise growth
| Year | Invested | Value at year end |
|---|---|---|
| 1 | ₹1,00,000 | ₹1,05,000 |
| 2 | ₹1,00,000 | ₹1,10,250 |
| 3 | ₹1,00,000 | ₹1,15,763 |
| 4 | ₹1,00,000 | ₹1,21,551 |
| 5 | ₹1,00,000 | ₹1,27,628 |
What is compound interest?
Compound interest is interest that earns interest. Each time interest is credited it is added to the principal, so the next credit is calculated on a larger base — and the interest starts earning interest of its own. Over short periods the difference from simple interest is small; over decades it is the difference between saving and building wealth.
This calculator works for any compounding product: enter the principal, the annual rate, the tenure and how often interest is credited — yearly, half-yearly, quarterly or monthly — and it returns the maturity value, total interest and a year-wise growth table.
The compound interest formula
A = P × (1 + r ÷ n)^(n × t)
- A — the maturity value
- P — the principal you invest
- r — the annual rate as a decimal (5% = 0.05)
- n — compounding periods per year: 1 yearly, 2 half-yearly, 4 quarterly, 12 monthly
- t — the tenure in years
Total interest is simply A − P. The more often interest is credited (higher n), the slightly higher the outcome for the same quoted rate.
How to use this calculator
- Enter the principal amount — ₹1,000 to ₹1 crore.
- Set the interest rate with the slider (1% to 30%; default 5%).
- Set the time period in years and months, up to 40 years.
- Pick the compounding frequency — yearly, half-yearly, quarterly or monthly. Match it to your product: Indian bank FDs compound quarterly, many bonds pay half-yearly, and most quoted CAGR figures assume yearly.
- Read the maturity value, total interest and the year-wise growth table.
A worked example
₹1,00,000 at 5% p.a. for 5 years, compounded yearly:
- Principal: ₹1,00,000
- Total interest: ₹27,628.16
- Maturity value: ₹1,27,628.16
Simple interest would have paid ₹25,000 — compounding adds ₹2,628 without any extra saving. Stretch the horizon and the effect dominates: ₹1,00,000 at 8% for 10 years grows to ₹2,15,892.50, more than doubling.
Does compounding frequency matter? ₹1,00,000 at 5% for 5 years
| Compounding | Maturity value | Total interest |
|---|---|---|
| Yearly | ₹1,27,628.16 | ₹27,628.16 |
| Half-yearly | ₹1,28,008.45 | ₹28,008.45 |
| Quarterly | ₹1,28,203.72 | ₹28,203.72 |
| Monthly | ₹1,28,335.87 | ₹28,335.87 |
Monthly compounding beats yearly by about ₹708 here — real, but modest. Frequency matters more at higher rates and longer tenures; the rate itself and the time you stay invested matter most.
Simple interest is always calculated on the original principal, so it grows in a straight line. Compound interest is calculated on principal plus accumulated interest, so it accelerates. At 5% for 5 years on ₹1,00,000: ₹25,000 simple versus ₹27,628 compounded yearly — and the gap widens every additional year.
Divide 72 by the annual rate to estimate the years needed to double your money. At 8%, 72 ÷ 8 = 9 years — and indeed ₹1,00,000 at 8% compounded yearly reaches ₹2,15,892.50 in 10 years. It is an approximation, but a useful sanity check on any projection.
Match the product, not the biggest number. Indian cumulative FDs compound quarterly; post office time deposits also compound quarterly; many bonds pay half-yearly; mutual-fund CAGR figures assume yearly. Using the wrong frequency typically shifts the result by well under 1%.
The calculator is product-agnostic, and tax follows the product. FD and RD interest is taxed at your slab rate every year. PPF interest is fully exempt. Equity mutual-fund growth is taxed only on sale — long-term gains above ₹1.25 lakh a year at 12.5% for FY 2025-26.
Yes — loans compound too. Credit-card balances at 36-42% annualised and unpaid interest on any loan grow by exactly the same math. The formula is neutral; which side of it you are on is not.
