How to use the SIP Calculator
- Enter the monthly SIP amount.
- Enter a realistic expected annual return.
- Enter the number of years and an optional yearly step-up.
- Press Calculate.
Formula
FV = P × [((1 + i)ⁿ − 1) ÷ i] × (1 + i)
P = monthly instalment, i = annual return ÷ 12 ÷ 100, n = number of months. The extra (1 + i) is because each SIP is invested at the start of the month.
Examples
- ₹10,000 a month at 12% for 15 years: invested ₹18 lakh, estimated value ≈ ₹50.45 lakh.
- With a 10% yearly step-up the same plan grows to about ₹86.8 lakh, from ₹38.1 lakh invested.
Frequently asked questions
What return should I assume?
Use a conservative figure. Long-run equity returns have varied widely; many planners test several rates such as 8%, 10% and 12%.
Is SIP better than a lump sum?
A SIP spreads purchases over time and suits regular income. A lump sum invested early can grow more if markets rise, but carries more timing risk.
