Goal SIP Calculator
Find the monthly SIP needed to reach a target amount by a chosen year.
About the Goal SIP Calculator
Enter your target amount, how many years you have, the expected return and anything already invested towards it. The calculator works backwards to the monthly SIP you need, the total you'll put in and a chart of the path to the goal.
The SIP is the instalment whose future value, invested at the start of each month, equals the target minus what your existing investments will grow to.
The formula
SIP = Goal ÷ ( ((1 + i)ⁿ − 1) ÷ i × (1 + i) )
- i
- monthly return = yearly ÷ 12
- n
- months
Worked example
₹25 lakh in 10 years at 12% a year, starting from nothing
- i = 1% a month, n = 120
- SIP needed: ₹10,760 a month
- You put in ₹12.9 lakh; growth supplies the rest
Things to keep in mind
- Assumes a steady return; build in a margin or review the plan every year.
Questions people ask
Should I adjust for inflation?
Yes: inflate today's cost of the goal first (for example with the inflation calculator).
Why start of the month?
Most SIPs debit early in the month, so each instalment earns that month's return.
