What is a Savings Goal?
A Savings Goal Calculator is a financial planning tool that tells you precisely how much to invest every month to reach a specific target amount within a defined time frame. Rather than telling you how much your investments will grow to (a forward calculation), it works in reverse ā given the destination and the timeline, it calculates the route.
The calculator handles the most common real-world scenario: you already have some savings, and you want to know how much more you need to contribute monthly. Your existing lump sum is compounded at the annual return over the full period, and only the remaining shortfall is allocated to monthly SIP contributions.
For Indian households, goal-based savings planning is essential because major financial milestones ā children's education, a home down payment, a car, or retirement ā require specific corpus sizes that are only reachable with disciplined monthly investment starting early. A ā¹50 lakh corpus needed in 10 years requires roughly ā¹22,000 per month at 12% returns. The same corpus needed in 15 years requires only ā¹11,000 per month ā every year of delay roughly doubles the required contribution.
The calculator also shows the total amount invested and the returns earned, giving a clear picture of how much of your goal will be funded by compounding versus your own contributions. For a long 15ā20 year goal at equity-like returns, the returns component typically exceeds the invested amount.

Worked example: Goal ā¹50 lakh in 10 years, existing savings ā¹2 lakh, 12% annual return. 1. FV of ā¹2 lakh in 10 years at 12%: ā¹2,00,000 Ć (1.12)Ā¹ā° = ā¹6,21,170 2. Remaining SIP target: ā¹50,00,000 ā ā¹6,21,170 = ā¹43,78,830 3. r_monthly = 12% Ć· 12 = 1%; n = 120 months 4. Monthly SIP = ā¹43,78,830 Ć 0.01 Ć· [(1.01)Ā¹Ā²ā° ā 1] Ć· 1.01 = ā¹19,273/month
