SIP Calculator — Estimate Your Mutual Fund Growth
See what your monthly SIP can grow into — with optional annual step-ups and a reverse mode that tells you the SIP needed for any target. 100% private — everything is computed in your browser.
Invested vs gains
Where your corpus comes from
Year-wise growth
Watch compounding accelerate — the gold bars (gains) outgrow the navy (your money) over time.
Navy = what you put in · Gold = growth on top. Hover a bar for that year's numbers. Notice how the gold portion — compounding — does the heavy lifting in later years.
How a SIP builds wealth
A Systematic Investment Plan (SIP) invests a fixed amount in a mutual fund every month — automatically, like a recurring deposit, except your money buys fund units at that month's price. When markets fall you get more units; when they rise you get fewer. This rupee-cost averaging smooths out market timing, which is why SIPs suit salaried investors far better than trying to "buy the dip."
The real engine is compounding: your gains start earning their own gains. Early on, your contributions dominate the corpus. But look at the year-wise chart above — somewhere around year 6–7, the gold bars (gains) start outgrowing the navy bars (your money). From there, time does more work than you do. That's why starting early beats investing more later.
Then there's the step-up SIP, the highest-leverage move most investors ignore. Increase your SIP 10% every year — roughly matching a salary hike — and a ₹10,000 monthly SIP over 10 years at 12% grows from about ₹22.4 lakh to about ₹32.7 lakh. Same discipline, one extra habit, roughly 46% more wealth. If your income rises and your SIP doesn't, you're leaving compounding on the table.
How to use this page: in Grow my SIP mode, enter what you can invest today and see the projection. In I have a target mode, enter the corpus you want — say ₹1 crore — and it tells you the monthly SIP needed to get there. Treat every projection as an illustration, not a promise: markets fluctuate, and reviewing your plan once a year beats setting and forgetting it.
Absolute returns vs XIRR
Two numbers you'll see on SIP statements, and they mean different things. Absolute return is the simple one: (final value − invested) ÷ invested. For Example 1 above: (22,40,359 − 12,00,000) ÷ 12,00,000 ≈ 86.7% over 10 years. It tells you how much your money grew in total — but it ignores when each instalment went in.
XIRR (extended internal rate of return) is the annualised return that accounts for the timing of every instalment — money invested in year 9 had far less time to grow than money invested in year 1. XIRR is the fair way to compare a SIP against a fixed deposit or another fund, because it answers "what yearly rate would produce this result?" When someone quotes a SIP "return", XIRR is usually what they mean — and it's the number to compare when choosing between funds.
Worked examples
Example 1 — ₹10,000/month × 10 years @ 12%
Effective monthly rate i = (1.12)1/12 − 1 ≈ 0.009489 (so 12% compounds to exactly 12% a year — simply dividing by 12 would overstate it), n = 120 months.
Corpus = 10,000 × ((1.009489120 − 1) / 0.009489) × 1.009489 = ₹22,40,359.
You invested ₹12,00,000 — compounding added ₹10,40,359 in gains.
Example 2 — same plan with a 10% annual step-up
Year 1: ₹10,000/mo, year 2: ₹11,000/mo, … year 10: ₹23,579/mo.
Total invested rises to ₹19,12,491 — but the corpus jumps to ₹32,68,898, with ₹13,56,407 in gains. The step-up costs you ₹7.1 lakh more in contributions and returns ₹10.3 lakh extra corpus.
Example 3 — reverse: what SIP builds ₹1 crore in 10 years @ 12%?
With effective monthly rate i ≈ 0.009489: required monthly SIP = 1,00,00,000 × 0.009489 / ((1.009489120 − 1) × 1.009489) = ₹44,636/month.

Frequently asked questions
What is a SIP?
A Systematic Investment Plan invests a fixed amount in a mutual fund every month automatically. Your money buys fund units at that month's NAV — more units when markets are down, fewer when they're up. This rupee-cost averaging plus compounding over years is what builds wealth steadily without timing the market.
Is SIP safe? Can I lose money?
A SIP is not risk-free. It invests in market-linked mutual funds, so your corpus moves with the market and can fall — especially over short periods. What a SIP does is reduce timing risk through rupee-cost averaging; it does not eliminate market risk. Longer horizons (7+ years in equity funds) have historically smoothed out volatility, but no return is guaranteed.
What annual return should I assume?
It depends on the fund type and horizon. Long-term equity SIPs are commonly modelled at 10–12% in India, while debt or hybrid funds are modelled lower. These are planning assumptions, not promises — actual returns will differ. When in doubt, run the calculator at a conservative rate (e.g. 10%) so your plan survives a below-average decade.
Can I pause or skip my SIP?
Yes. Most fund houses let you pause a SIP for a few months, and a missed instalment simply means no units are bought that month — there is generally no penalty from the fund (your bank may charge for a failed auto-debit). Pausing doesn't sell your existing units; they stay invested. But frequent pauses break the compounding habit the SIP is built on.
Step-up SIP vs plain SIP — which is better?
Usually the step-up, if your income is growing. A step-up keeps your investments proportional to your earnings instead of letting inflation shrink them in real terms. In our worked example, a 10% annual step-up turned ₹22.4 lakh of maturity into ₹32.7 lakh over the same 10 years. The trade-off is purely budgetary: only step up what you can sustain.
SIP vs lump sum — which is better?
Neither wins always. A lump sum invested just before a long rally beats a SIP; a SIP beats a lump sum invested just before a crash, because it buys cheaper through the fall. Since nobody can reliably predict which comes next, SIPs are the practical default for salaried investors — they remove the timing decision entirely.
Are SIP returns taxed?
Yes. For equity mutual funds, long-term gains (held over 1 year) are taxed at 12.5% on gains above ₹1.25 lakh per financial year (rule effective July 2024). Short-term gains (under 1 year) are taxed at 20%. Debt fund gains are taxed at your income slab rate. Factor this into real-world planning — this calculator shows pre-tax projections.
Are these projections guaranteed?
No. Mutual-fund returns follow markets and fluctuate — a projection is an illustration at your assumed rate, not a promise. Review your SIP annually, rebalance as goals approach, and never invest emergency money in equity. This calculator's figures are estimates computed in your browser.
I saw a reel saying ₹2,000/month becomes ₹65 lakh. Is that real?
The maths is roughly right — but it hides two big assumptions. ₹2,000/month for 30 years at ~12% annual return grows to about ₹65–70 lakh, on ₹7.2 lakh invested. The catch: it needs three full decades of uninterrupted investing at a return no fund guarantees. At a more conservative 10%, the same SIP reaches only about ₹45.6 lakh — and inflation will have shrunk what ₹65 lakh buys by then. So the claim isn't fake, but it's a best-case illustration dressed up as a promise. Run it in the calculator above with your own numbers.
