How do I calculate the maturity value of a monthly SIP?

Enter your monthly investment amount, the expected annual return and the number of years into AnyTool SIP Calculator, and it instantly shows the maturity value, the total you invested and the estimated gains. A SIP is a monthly mutual-fund annuity, so it uses maturity = P × [((1 + i)ⁿ − 1) ÷ i] × (1 + i), where P is the monthly amount, i is the monthly return (annual % ÷ 12 ÷ 100) and n is the number of months, with each instalment invested at the start of the month. You can switch to a step-up SIP that raises the instalment a fixed percent each year, or to target mode, which solves the monthly SIP needed to reach a goal corpus. A pure-SVG growth chart and a year-by-year table show invested versus gains, you can display in ₹, $, € or £, and everything is calculated in your browser, so nothing is uploaded.

  • Maturity = P × [((1 + i)ⁿ − 1) ÷ i] × (1 + i), instalments at the start of each month
  • Regular, step-up (annual % increase) and target-amount (solve the SIP) modes
  • Maturity value, total invested and estimated gains, with a growth chart
  • Full year-by-year table of monthly amount, invested, gains and corpus

What is

SIP (Systematic Investment Plan)

A Systematic Investment Plan (SIP) is a way of investing a fixed amount in a mutual fund at regular intervals, usually monthly, so that units are bought across market ups and downs (rupee-cost averaging) rather than in one lump sum. The maturity value is the future value of that monthly annuity, maturity = P × [((1 + i)ⁿ − 1) ÷ i] × (1 + i), where P is the instalment, i is the periodic return and n the number of instalments. A step-up SIP increases the instalment by a fixed percentage each year. Because returns are market-linked, the projected value assumes a constant expected return and is an illustration, not a guarantee.

Frequently Asked Questions

Maturity equals P times ((1 + i) to the power n, minus 1) divided by i, times (1 + i), where P is the monthly amount, i the monthly return and n the months.

A SIP maturity is the future value of a monthly annuity: maturity = P × [((1 + i)ⁿ − 1) ÷ i] × (1 + i). P is the monthly investment, i is the monthly return — the annual return divided by 12 and by 100 — and n is the total number of monthly instalments, with each instalment invested at the start of the month. For example, ₹5,000 a month for 10 years at 12% a year grows to about ₹11.6 lakh, of which ₹6 lakh is invested and the rest is gains. AnyTool computes this live and also handles step-up SIPs and a target-amount mode.

A step-up SIP raises your monthly amount by a fixed percent each year, so you invest more as your income grows and the corpus ends up much larger.

In a step-up (or top-up) SIP you increase the monthly instalment by a set percentage at the start of every year — for example ₹5,000 in year one, 10% more in year two, and so on. Because you invest progressively more and each higher instalment still compounds for the remaining years, the maturity value is substantially larger than a flat SIP of the same starting amount. AnyTool lets you enter the step-up percentage and shows the rising instalment, the extra amount invested and the larger corpus in the year-by-year table.

Switch to target mode, enter your goal, expected return and years, and the calculator solves the monthly SIP you need — with or without an annual step-up.

Target mode answers the reverse question: given a goal corpus, an expected annual return and a horizon, what monthly SIP gets you there? AnyTool solves it by searching for the starting monthly amount whose maturity equals your goal, and it works with an optional annual step-up too, so you can plan a rising instalment instead of a flat one. The required SIP, the total you would invest and the estimated gains all update live as you change the goal or assumptions.

No — SIP returns are market-linked and can be negative, so the figure is a projection at an assumed rate; and nothing is uploaded, every calculation runs in your browser.

SIP returns are not guaranteed: they depend on the market, vary year to year and can be negative, and past performance does not predict future results. A SIP averages your purchase price across ups and downs but does not remove the risk of loss, and the projection assumes a single constant return. The figures are nominal and exclude expense ratios, exit loads, capital-gains tax and inflation, so treat them as a planning illustration. AnyTool SIP Calculator runs entirely in your browser, so your amounts are never sent to a server and the page works offline.

Detailed Explanation

Methodology

How the SIP Calculator Works

AnyTool SIP Calculator projects a monthly mutual-fund investment in the browser. A regular SIP is the future value of a monthly annuity, maturity = P × [((1 + i)ⁿ − 1) ÷ i] × (1 + i), where P is the monthly amount, i is the monthly return (annual % ÷ 12 ÷ 100) and n is the number of months, with each instalment invested at the start of the month. For a step-up SIP the calculator runs the projection one year at a time, raising the monthly instalment by the step-up percentage at the start of each year and carrying the accumulated corpus forward, so every higher instalment still compounds for the remaining years. A target-amount mode solves the starting monthly SIP whose maturity equals a goal corpus by a monotonic search. The 0% case degrades cleanly to simply the money invested. All arithmetic is pure client-side JavaScript shared through a reusable, unit-tested investment engine.

  • Maturity = P × [((1 + i)ⁿ − 1) ÷ i] × (1 + i); instalments at the start of each month
  • Step-up SIP raises the monthly amount a fixed percent each year, compounded year by year
  • Target mode solves the monthly SIP needed for a goal by a monotonic search
  • Estimated gains = maturity − total invested; 0% return returns just what was invested
  • All math is client-side JavaScript in a reusable investment engine — no server round-trip
Use Cases

Modes, Growth Chart and Year-by-Year Schedule

The calculator offers three modes — regular SIP, step-up SIP and target amount — alongside a pure-SVG growth chart and a full year-by-year table. The chart stacks each year into two bands, cumulative invested and cumulative gains, so the widening gains band makes compounding visible without any chart library. The table lists every year’s monthly instalment (which rises in step-up mode), the amount invested that year, the gains credited and the closing corpus, and is scrollable for long horizons. A summary shows the maturity value, the split between invested and gains, and in target mode the required starting monthly SIP. A currency selector (₹ default, then $, € and £) controls display only.

  • Three modes: regular SIP, step-up SIP and target-amount (solve the SIP)
  • Pure-SVG stacked growth chart: cumulative invested and gains by year
  • Year-by-year table of monthly amount, invested, gains and closing corpus
  • Maturity split shown as invested vs gains percentages
  • Currency display in ₹ / $ / € / £ — display only, engine is currency-agnostic
Limitations

Market-Linked Returns, Not a Guarantee

The calculator assumes a single constant expected return every year, so it is an illustration of how a SIP could grow rather than a forecast of any real fund. SIP returns are market-linked: they vary year to year, can be negative, and past performance does not predict future results. A SIP averages your purchase price across market ups and downs through rupee-cost averaging but does not eliminate the risk of loss. The figures are nominal and exclude expense ratios, exit loads, capital-gains tax and the erosion of purchasing power from inflation. The page states these limits plainly and recommends a conservative return assumption for planning.

  • Assumes one constant expected return every year — an illustration, not a forecast
  • SIP returns are market-linked, vary year to year and can be negative
  • Rupee-cost averaging reduces timing risk but does not remove the risk of loss
  • Excludes expense ratios, exit loads and capital-gains tax
  • Nominal figures — does not adjust for inflation or purchasing power
Privacy & Security

Privacy and Offline Use

Because all computation runs in the browser, your monthly amount, expected return, horizon, step-up and goal are never sent to a server, there is no account or tracking, and the page works offline after first load. The currency selector only changes how numbers are displayed; the engine itself is currency-agnostic and works in plain numbers. The SIP Calculator is built on the same shared, unit-tested investment engine as the compound-interest and other savings tools, so its behaviour is consistent across the calculator category.
