Project the final corpus of a Systematic Investment Plan (SIP) — monthly mutual fund investment over years, with compound growth at your expected rate. Supports step-up SIP (where your monthly contribution rises annually to match salary growth). All math is client-side, no signup.
Increase your monthly SIP by this % each year (matches salary growth).

The SIP math
A standard SIP makes a fixed contribution at the end of each month, growing at the assumed monthly return (annual_rate / 12). Future value after N months:
FV = P × [((1+r)ᴺ − 1) / r]
where P is the monthly contribution and r is the monthly return rate. For step-up SIP, the contribution P grows each year by the step-up percentage. The calculator handles both cases.
Compounding is the magic
A ₹10,000 monthly SIP for 30 years at 12% annual return ends at ~₹3.5 crore. You invested ₹36 lakh — the other ₹3.1 crore is pure compound growth. Time in the market matters far more than picking the perfect fund. Starting 10 years earlier with the same SIP roughly doubles the final corpus.
Step-up SIP example
₹10,000/mo flat, 15 years, 12% return → ~₹50 lakh.
₹10,000/mo + 10% annual step-up, 15 years, 12% → ~₹85 lakh.
Because step-up matches typical salary growth, it's painless to commit to. Most fund houses (Zerodha Coin, Groww, MFU, AMC apps) support step-up SIP natively at signup.
A Systematic Investment Plan is a way to invest in mutual funds — you commit to a fixed monthly amount (e.g. ₹10,000), and the AMC buys units of the chosen fund every month on a chosen date. SIPs benefit from rupee-cost averaging (buying more units when prices are low, fewer when high) and the compounding of returns over time.
What return should I assume?
Nifty 50 / large-cap equity: historical long-run ~12% nominal CAGR. Balanced (hybrid) funds: ~10%. Debt funds: 6-8%. Small-cap equity: potentially 15%+ but with much higher volatility. The default 12% used here is realistic for a long-horizon equity SIP; reduce to 10% for conservative planning.
How does step-up SIP work?
A step-up SIP increases your monthly contribution every year by a fixed percentage (e.g. +10% each year). It matches the typical salary growth curve — you invest more as you earn more. Step-up dramatically increases the final corpus: a ₹10,000 SIP with 10% annual step-up over 20 years at 12% return builds nearly 2x the corpus of a flat ₹10,000 SIP.
Is SIP better than lumpsum?
Mathematically, lumpsum wins if the market only goes up — every additional month you delay means less compounding. But that's rarely how investing works in practice. SIPs win on three real-world fronts: (1) you don't need a big lumpsum to start, (2) you don't need to time the market, (3) rupee-cost averaging reduces the impact of buying at peaks. For most people, SIP is the better behavioural choice. Combining a starter lumpsum with ongoing SIP is also common.
Are SIP returns taxed?
Equity mutual funds (≥65% equity): gains held for >1 year are LTCG taxed at 12.5% above ₹1.25 lakh exemption per year (effective FY 2024-25). Held for <1 year: STCG at 20%. Debt mutual funds (purchased after April 2023): taxed as per your income slab regardless of holding period. The calculator shows gross returns; reduce by your effective tax rate to estimate net returns.
When should I stop or pause a SIP?
Generally don't — pausing SIPs in market downturns is the opposite of what disciplined investing requires. Pause only if (1) you genuinely need the cash for living expenses, (2) the fund itself has fundamentally changed (manager change, mandate change, persistent underperformance vs benchmark over 3+ years). Switching to a better fund is fine; stopping out of fear is usually not.
Is this calculator accurate?
Yes for the math — uses standard monthly-compounding FV formula and applies step-up annually. Limitations: it assumes a constant rate of return (real returns vary year to year), doesn't account for fund expense ratios (typically 0.5%-2% per year, deducted from NAV), exit loads, or taxes. For a more realistic projection: subtract 1-1.5% from your assumed return to account for expenses and taxes.
