Quick start

How to use the SIP calculator

Enter your monthly investment, expected annual return and tenure to see the maturity value, total invested and total returns from a Systematic Investment Plan.

  1. Step 1
    Pick SIP or lumpsum

    SIP for monthly recurring investments; Lumpsum for a one-time investment compounding over n years.

  2. Step 2
    Enter amount and rate

    Monthly investment (or principal), expected annual return %, and tenure. Indian Rupee is the default currency.

  3. Step 3
    Read the breakdown

    See maturity value, total invested, total returns, and a year-by-year growth table that shows the compounding curve.

In-depth guide

SIP calculator — what a monthly investment grows into

A Systematic Investment Plan (SIP) is the most common way Indian retail investors put money to work — a fixed monthly amount into a mutual fund, automated via mandate. This calculator shows what that monthly habit compounds into over time, plus a lumpsum alternative for comparison.

The SIP formula

The standard SIP future-value formula (annuity-due):

FV = M · [((1+i)^n − 1) / i] · (1+i)

  • M — monthly investment
  • i — monthly rate (annual ÷ 12 ÷ 100). A 12% annual return gives i = 0.01.
  • n — number of months. A 20-year SIP has n = 240.

The trailing (1+i) factor is the annuity-due adjustment — it assumes you invest at the start of each month (so the money earns one extra month of compounding). This matches AMFI's standard SIP calculator convention.

The compounding curve in numbers

A ₹10,000 monthly SIP at 12% annual return:

  • After 5 years: invested ₹6 lakh, maturity ~₹8.2 lakh (₹2.2L returns)
  • After 10 years: invested ₹12 lakh, maturity ~₹23.2 lakh (₹11.2L returns)
  • After 15 years: invested ₹18 lakh, maturity ~₹50.5 lakh (₹32.5L returns)
  • After 20 years: invested ₹24 lakh, maturity ~₹99.9 lakh (₹75.9L returns)
  • After 25 years: invested ₹30 lakh, maturity ~₹1.9 crore (₹1.6 crore returns)

The returns become dominant past year 10. This is why fund managers, AMFI ads and personal-finance writers all hammer the same message: start early, stay invested. A 25-year SIP at the same monthly amount delivers ~4× the maturity of a 15-year SIP — and ~12× the returns.

SIP vs lumpsum

Mathematically, if returns are positive and constant, a lumpsum invested at year 0 always beats spreading the same total across n years — the early money compounds longer.

In practice, SIP usually wins for retail investors because:

  • You rarely have a lumpsum equal to your total planned SIP — you earn it month by month.
  • SIP averages your purchase cost (rupee-cost averaging) — you buy more units when NAV is low, fewer when it's high.
  • SIP enforces discipline. Most people fail at lumpsum timing.

The lumpsum tab here uses standard compound interest (FV = P · (1+r)^t) and is useful for one-off investments — bonus money, inheritance, a windfall.

What this calculator doesn't capture

Real-world SIP returns deviate from the smooth curve shown here for several reasons:

  • Volatility — actual equity returns vary year-to-year (−30% in a crash year, +40% in a bull year). The constant-rate model averages this out, which understates downside but also understates compounding when the early years happen to be strong.
  • Inflation — figures here are nominal. To get real (inflation-adjusted) value, plug in a lower rate (e.g. 6% if you expect 12% nominal returns and 6% inflation).
  • Taxes — equity LTCG above ₹1 lakh/year is taxed at 10%. Debt-fund LTCG is taxed at slab. The figures here are pre-tax.
  • Expense ratio — direct plans charge 0.5–1%, regular plans 1.5–2.5%. This reduces effective returns by the same amount each year. Plug in the expense-ratio-adjusted rate for a realistic estimate.
  • Step-ups — most disciplined SIPs increase by 5–10% per year as income grows. This tool assumes a constant monthly amount.

Educational only — not financial advice. Past performance doesn't predict future returns. Talk to a SEBI-registered investment adviser for personal planning.

Common pitfalls

  • Confirm rates, compounding frequency, tax year, dates, and rounding before acting on the result.
  • Fees, penalties, inflation, and local rules can make real outcomes differ from simple formulas.
  • Treat results as guidance, not financial, tax, legal, or investment advice.

Frequently asked questions

Is my data uploaded anywhere?

No. The SIP and lumpsum math runs entirely in your browser. Nothing is sent to a server, logged, or stored.

What's the SIP formula?

FV = M · [((1+i)^n − 1) / i] · (1+i), where M is the monthly investment, i is the monthly rate (annual ÷ 12 ÷ 100), and n is the number of months. The trailing (1+i) is the annuity-due adjustment — it assumes you invest at the start of each month, the convention AMFI and most Indian mutual-fund houses use.

What rate should I assume?

Historical equity-mutual-fund returns in India have averaged 12–15% CAGR over 15+ year windows, with significant year-to-year variation. Debt funds historically deliver 6–8%. Hybrid funds sit in between. These are not guarantees — past performance doesn't predict future returns. Pick a conservative rate (10–12%) for planning.

Does this account for inflation?

No. The maturity value shown is in today's currency units at nominal returns. To estimate real (inflation-adjusted) value, use a lower rate — e.g. if you expect 12% nominal and 6% inflation, plug in 6% to see what the corpus would buy in today's terms.

Does this account for taxes?

No. Capital gains tax on equity mutual funds in India is 10% on long-term gains (held >1 year) above ₹1 lakh per year. Debt funds are taxed at slab rates as of April 2023. The figures here are pre-tax — actual take-home is lower. Talk to a CA for your specific tax situation.

SIP vs lumpsum — which is better?

Mathematically, if markets only go up at a steady rate, a lumpsum at year 0 always beats spreading the same money over n years (because the early money compounds longer). In practice, SIP wins for most retail investors because it sidesteps timing risk and enforces savings discipline. If you have a lumpsum and the market is at all-time highs, SIP into the same fund over 12 months is a defensible middle ground.

What is annuity-due vs annuity-ordinary?

Annuity-due assumes payments at the start of each period (what this tool uses, matching AMFI convention). Annuity-ordinary assumes payments at the end of each period. The difference is one extra month of compounding — for a 12% SIP over 20 years, annuity-due gives ~1% higher maturity. Both are common; this tool uses the SEBI/AMFI standard.

Can I model step-up SIPs?

Not yet — this tool assumes a constant monthly investment. A step-up SIP (where you increase the SIP amount by a fixed % every year) typically delivers 30–50% more at maturity for the same starting amount. We may add step-up modelling in a future version.
