What is a SIP Calculator?
A Systematic Investment Plan (SIP) lets you invest a fixed amount in a mutual fund every month instead of putting in one lump sum. Each instalment buys units at that month's price, so over time your average purchase cost smooths out across market ups and downs — the effect most people mean when they say "rupee cost averaging."
This calculator projects the maturity value of a SIP given a monthly amount, an expected annual return, and how many years you plan to stay invested. It assumes each month's instalment is invested at the start of the month, which is how most fund houses and calculators treat SIP dates.
How the maturity value is calculated
P is your monthly investment, r is the monthly rate (annual return ÷ 12), and n is the total number of instalments. The extra (1+r) accounts for each instalment being invested at the start of the month rather than the end.
Move the sliders or type directly into the fields — the maturity value, total invested amount and estimated gains update instantly. The expected return is an assumption you control; equity mutual funds don’t guarantee any fixed rate, so it helps to test a couple of scenarios (say 10%, 12% and 14%) rather than anchoring on one number.
Frequently asked questions
Is the SIP return guaranteed?
No. Mutual fund returns are market-linked and not guaranteed. The rate you enter here is an assumption for planning purposes, based on whatever return expectation you consider reasonable for the fund category.
Does this account for expense ratio or exit load?
No — the return rate you enter should already be your post-expense-ratio expectation. Exit load only applies if you redeem early, which this maturity-value projection doesn’t model.
What’s the difference between this and the Lumpsum calculator?
This tool assumes equal monthly instalments. If you’re investing one amount today instead, use the Lumpsum Calculator, which compounds a single principal instead of a stream of instalments.
Why does the calculator assume investment at the start of the month?
It matches how most AMC and industry SIP calculators compute maturity value. If your SIP date is later in the month, actual returns will be marginally lower than shown here.
