SIP, lumpsum & retirement calculator
See what a monthly SIP or a one-time investment grows to, in rupees and in today’s money, and how much you need to invest every month to retire comfortably.
Equity funds have averaged 10–12% over long periods; nothing is guaranteed.
Raise the SIP every year, e.g. with your increment.

Life expectancy, with a margin.
What you’d spend in retirement, at today’s prices (excluding EMIs that will be over).
Usually lower: mostly debt, FDs, SCSS.
EPF, PPF, NPS, mutual funds earmarked for retirement.
Growth
Year by year
Returns are assumptions, not promises: market-linked investments go up and down, and the order of returns matters. SIPs are invested at the start of each month with the yearly return divided by 12, as most Indian mutual-fund calculators do. Values are before tax: equity mutual-fund gains held over a year are taxed at 12.5% above ₹1.25 lakh a year, and FD interest at your slab rate. The retirement plan withdraws a year’s expenses at the start of each year, rising with inflation, while the rest earns the post-retirement return.

About this calculator
Three calculators in one. The SIP calculator shows what a monthly investment grows to, with an optional yearly step-up and a starting lumpsum, both in rupees and in today’s money after inflation. The lumpsum calculator works out compound interest on a one-time investment or fixed deposit, compounded yearly, half-yearly, quarterly or monthly. The retirement planner grows your current expenses to your retirement age, works out the corpus needed to last until your chosen age, and the monthly SIP that builds it.
Frequently asked questions
- How is SIP maturity value calculated?
- Each instalment is invested at the start of the month and grows at the yearly return divided by 12. For a flat SIP, maturity = SIP × [((1 + i)n − 1) ÷ i] × (1 + i). ₹10,000 a month at 12% for 10 years grows to about ₹23.2 lakh.
- What is a step-up SIP?
- A SIP that rises by a fixed percentage every year, usually with your increment. A 10% yearly step-up on ₹10,000 at 12% for 10 years grows to about ₹33.7 lakh instead of ₹23.2 lakh.
- How much corpus do I need to retire?
- Enough to pay your expenses, rising with inflation, from retirement until your life expectancy, while the remaining money keeps earning a lower post-retirement return. The retirement tab works out that corpus and the monthly SIP needed to build it.
- How is FD interest compounded in India?
- Most bank FDs compound quarterly. ₹1 lakh at 7% for 5 years compounded quarterly grows to about ₹1,41,478.
