CalculatorsWhat a monthly SIP could grow into — including step-up, lumpsum and goal-solving modes.

Projections only. Market returns are not fixed and not guaranteed — a 12% average does not mean 12% every year. This is not investment advice.
How this is calculated
SIP (contributions at the start of each month) FV = P x [((1 + i)^n - 1) / i] x (1 + i) P = monthly instalment i = monthly rate = annual rate / 12 / 100 n = number of months Lumpsum FV = P x (1 + r/100)^years
Read this before you rely on the number
This is a projection, not financial advice.
This is a projection from a return rate you chose, not a forecast. Markets do not deliver a steady annual percentage — the same average return arriving in a different order produces a different corpus, and the difference is largest near the end of a long SIP. Mutual fund investments are subject to market risk, and past performance is not indicative of future results.

How it works
A SIP invests a fixed amount every month, and each instalment grows for however long it stays invested. The first instalment compounds for the full period; the last one for barely a month. The formula adds up all of those different growth periods in one step.
Note the trailing (1 + i) on the SIP formula. Indian SIPs debit at the start of the month, so every instalment earns one extra month of growth compared with an end-of-month assumption. Calculators that drop that factor under-report the corpus by roughly one month's return — on a ten-year SIP at 12%, that is about ₹23,000 on a ₹10,000 monthly investment.
A step-up SIP raises the instalment once a year, usually in line with a salary increase. Because the extra money goes in early enough to compound, a modest 10% annual step-up makes a large difference over long periods — often more than chasing a higher return would.
Worked example
₹10,000 a month for 10 years at an assumed 12% a year
- i = 12 / 12 / 100 = 0.01
- n = 10 x 12 = 120 months
- (1 + i)^n = 1.01^120 = 3.300387
- FV = 10000 x [(3.300387 - 1) / 0.01] x 1.01
- FV = 10000 x 230.0387 x 1.01
Corpus ≈ ₹23,23,391 · invested ₹12,00,000 · returns ₹11,23,391
How to use it
- Pick a mode: a regular SIP, a step-up SIP that rises each year, a one-time lumpsum, or work backwards from a target corpus.
- Set the monthly amount, the return you want to assume, and the period.
- For a step-up SIP, set how much you will raise the instalment each year.
- In goal mode, enter the corpus you are aiming for and the calculator solves for the monthly SIP needed.
What this tool does not do
- Returns are projections from an assumed rate, not guarantees. Markets are volatile and can fall.
- It shows gross returns. It does not deduct expense ratio, exit load, or capital gains tax.
- It assumes a constant rate of return. Real returns vary year to year, sometimes dramatically.
- This is not investment advice. Speak to a registered adviser about your own situation.
Frequently asked questions
How is SIP return calculated?
FV = P x [((1+i)^n - 1) / i] x (1+i), where P is the monthly instalment, i is the monthly rate (annual rate divided by 12 and by 100), and n is the number of months. The final (1+i) accounts for instalments being invested at the start of each month.
What return should I assume?
Use something you can defend rather than something flattering. Indian equity funds have historically averaged roughly 10-14% over long periods, debt funds considerably less. Whatever you pick is an assumption — actual returns vary year to year and can be negative.
Is a step-up SIP really worth it?
Usually yes, and by more than people expect. Raising a ₹10,000 SIP by 10% a year over ten years invests far more money and gives the early increases time to compound. Try it against a flat SIP of the same starting amount in the calculator.
SIP or lumpsum — which is better?
A lumpsum invested at the start compounds for longer, so on paper it wins if markets rise steadily. A SIP spreads the entry price across many months, which reduces the risk of investing everything just before a fall. Most people also simply do not have a lumpsum available, which settles it.
Are the returns shown guaranteed?
No. Every figure here is a projection from the rate you entered. Mutual fund returns are not fixed, are not guaranteed, and a 12% average does not mean 12% in any particular year.
Does this account for tax or expense ratio?
No. It calculates gross returns at the rate you enter. Capital gains tax and the fund's expense ratio will both reduce what you actually receive. To approximate the effect of expenses, reduce your assumed return by the expense ratio.
What if I miss a SIP instalment?
The calculator assumes every instalment is paid. Missing one reduces both the invested amount and its compounding, though a single missed month over a long period has a small effect.
