SIP calculator

Estimate the maturity value of a monthly SIP from the amount, expected annual return, and duration.

Monthly investment Expected annual return (%) Duration (months)

Formula and algorithm

Future value = P × [((1 + i)^n − 1) ÷ i] × (1 + i)
P = monthly investment, i = monthly return = annual ÷ 12 ÷ 100, n = number of months.
Contributions are assumed at the start of each month (annuity-due); returns are an assumption, not a guarantee.

Input: ₹5,000/mo at 12% for 120 months

Output: ≈ ₹11,61,695

Invested ₹6,00,000; estimated gain ₹5,61,695.

Input: ₹5,000/mo for 10 years

Output: ₹6,00,000 invested

You put in ₹6 lakh; compounding does the rest.

Input: ₹5,000/mo at 0% for 120 months

Output: ₹6,00,000

With no return, the value equals the amount invested.

Is the SIP return guaranteed?

No. The rate is an assumption; actual mutual-fund returns vary and can be negative.

Start or end of month?

This uses start-of-month contributions (annuity-due), the common convention for SIP calculators.

Does it account for taxes or fees?

No. Expense ratios, exit loads, and capital-gains tax are not included.
