SIP & Lumpsum Calculator

Estimate what your mutual-fund investments could grow to — a monthly SIP or a one-time lumpsum.

SIP vs lumpsum

A SIP (Systematic Investment Plan) invests a fixed amount every month, which averages out your purchase price across market ups and downs — useful when you have a steady income rather than a big sum upfront. A lumpsum invests everything at once and benefits most when markets rise steadily afterwards.

The maths

For a SIP, each monthly instalment compounds for the months remaining, giving FV = P × (((1+i)^n − 1) ÷ i) × (1+i). A lumpsum simply grows as FV = P × (1+rate)^years. Here i is the monthly return and n the number of months.

Note: returns are assumed and constant. Real mutual-fund returns vary year to year and aren't guaranteed; this is a planning estimate, not advice.
