Goal Planning Calculator (SIP) - Monthly SIP Needed: Complete Guide
A Goal SIP Calculator (Reverse SIP Calculator) helps you determine how much monthly SIP you need to start today to achieve a specific financial target by a future date. Instead of calculating "how much will my SIP grow to?", this calculator works backwards from your goal — telling you exactly what monthly investment is required. This reverse approach makes goal planning concrete and actionable.
How Reverse SIP Calculation Works
The goal SIP calculator uses the reverse annuity formula:
Required SIP = FV × r / [(1 + r)ⁿ – 1] / (1 + r)
Where FV = Goal amount, r = monthly return rate, n = months
This tells you exactly how much to invest monthly to reach your goal. For example, to accumulate ₹1 crore in 15 years at 12% expected returns, you need a monthly SIP of approximately ₹20,018 — a surprisingly achievable number for most middle-class families.

These numbers show that even modest monthly SIPs, started early, can build substantial wealth.
