What Is Goal-Based SIP Planning?
A Goal SIP Calculator works in reverse compared to a regular SIP calculator. Instead of asking "how much will my monthly SIP grow to?", it answers: "how much do I need to invest monthly to reach my specific financial goal?"
Goal-based investing is the foundation of modern financial planning in India. Whether it's buying a house, funding a child's education, or building a retirement corpus, each goal has a specific target amount, time horizon, and inflation-adjusted cost that determines the required monthly SIP.
Goal SIP Formula — Reverse Calculation
Required Monthly SIP = FV × r / [(1 + r)^n − 1]
Where FV = future value / goal corpus, r = monthly expected return (annual rate / 12), n = months to goal.
Example: Goal = ₹1 crore in 15 years, expected return = 12% p.a.: r = 12/12/100 = 0.01; n = 180 Monthly SIP = 1,00,00,000 × 0.01 / [(1.01)^180 − 1] = ₹10,024/month
You need to invest just ₹10,024/month (total ₹18 lakh over 15 years) to accumulate ₹1 crore at 12% p.a. — the remaining ₹82 lakh is investment growth.
