SIP calculator

How this is calculated

i = R ÷ 12 ÷ 100, n = years × 12.
FV = P × [((1 + i)^n − 1) ÷ i] × (1 + i)  (each instalment invested at the start of the month). If i = 0, FV = P × n.
Optional: effective monthly rate i = (1 + R/100)^(1/12) − 1, which gives a slightly lower value.

Worked example

₹10,000 a month at 12% for 10 years: invested ₹12,00,000, estimated value ≈ ₹23,23,391.

Assumptions

• A constant return every month; real returns vary and can be negative.
• No exit loads, taxes or missed instalments.

Frequently asked questions

Why does this differ from my fund statement?

Statements use actual NAVs on each date. The calculator assumes one steady rate; use XIRR to measure your real return.

What return should I assume?

There is no right number. Try a range, for example 8%, 10% and 12%, to see how sensitive the result is.
