Enter your monthly investment, expected annual return, and duration. Ledger works out your estimated maturity value and a year-by-year growth breakdown.
Got a bonus, maturity payout, or any one-time amount you added along the way? Add each one below with the date you invested it — we'll grow it alongside your SIP from that point on.

A SIP grows through two things working together: a fresh contribution every month, and compounding on everything you've invested so far.
Assuming your investment happens at the start of each month and compounds monthly at your expected rate:
Maturity Value = P × [((1+r)n − 1) / r] × (1+r)
Where P is your monthly investment, r is your expected monthly return (annual rate ÷ 12 ÷ 100), and n is your total number of monthly installments. This is the same formula used by most SIP calculators - each month's contribution compounds for however long it's been invested, and all of it adds up at maturity.
Unlike your EMI or FD calculators, a SIP's actual growth depends entirely on real market performance - the rate you enter here is just an assumption for planning purposes. Real mutual fund returns fluctuate year to year, and can be negative in some years even if the long-term average is positive. Use this to get a feel for how contribution amount, rate, and time interact, not as a guaranteed outcome.
No. Unlike a Fixed Deposit, a SIP invests in mutual funds, which are market-linked. The "expected return" you enter is just an assumption for illustration - actual returns depend on market performance and can be higher or lower, including negative in some periods.
Since you invest a fixed amount every month regardless of the market price, you automatically buy more units when prices are low and fewer when prices are high. Over time this averages out your purchase cost - one of the reasons SIPs are often recommended over trying to time a lump sum investment.
SIPs suit people investing out of regular income who want to reduce timing risk through rupee cost averaging. A lump sum can outperform a SIP if invested right before a sustained market rise, but carries more timing risk. Many investors use both approaches for different money.
A step-up (or top-up) SIP increases your monthly investment periodically, often annually in line with salary increments, instead of staying fixed. This calculator assumes a fixed monthly amount throughout; a step-up SIP would reach a higher value for the same starting amount.
