SIP Goal Calculator
The SIP Goal Calculator works backwards from a target — enter your target corpus, expected annual return, and investment period, and it solves for the required monthly SIP amount you need to hit that goal, along with the total amount to invest and estimated returns. Adjust the sliders to see how raising your expected return by 1% or extending your tenure by two years changes the monthly SIP your goal-based systematic investment plan demands.

What is a SIP Goal Calculator?
A SIP goal calculator — also called a goal-based SIP calculator or reverse SIP calculator — works in the opposite direction to a standard SIP calculator. Instead of asking "how much will my ₹5,000/month SIP grow to?", it asks "how much do I need to invest each month to reach ₹50 lakh in 10 years?" You enter your target corpus, expected annual return, and investment period, and the tool calculates the required monthly SIP, the total amount to invest, and the estimated returns that compounding will contribute.
This goal-based approach to a systematic investment plan aligns far better with real financial planning. Most investors have specific goals — a child's higher education in 15 years, a house down payment in 5 years, a retirement corpus of ₹5 crore in 25 years — and the SIP calculator for target corpus gives you the exact monthly commitment required for each goal, rather than a projection from an arbitrary monthly amount. Start with the sip calculator for target amount in this group.
How the SIP Goal Calculator Works — Reverse Formula
The reverse SIP calculator uses the inverse of the Future Value of Annuity Due formula. Starting from the target corpus M, it solves for P (the monthly SIP amount):
P = M × r / [(1 + r)ⁿ − 1] × 1 / (1 + r)
- M = Target corpus (₹)
- r = Monthly return rate = Annual return ÷ 12 ÷ 100
- n = Total months = Years × 12
Example: Target ₹50 lakh in 10 years at 12% annual return → r = 0.01, n = 120. Required monthly SIP = ₹21,562. Total invested = ₹25.87 lakh. Estimated returns = ₹24.13 lakh. Compounding contributes nearly as much as your own deposits to hitting the goal — which is why extending the investment period by even 2–3 years reduces the required SIP dramatically. Try the goal-based SIP calculator above with 12 years instead of 10 for the same target and see the difference.
Setting Realistic SIP Goals
When using the SIP goal calculator, the three inputs interact in ways that can significantly change the required monthly SIP. Here are the key relationships to keep in mind for your systematic investment plan:
| Target | Tenure | Return Rate | Required Monthly SIP |
|---|---|---|---|
| ₹50 lakh | 10 years | 12% | ₹21,562 |
| ₹50 lakh | 15 years | 12% | ₹9,997 |
| ₹50 lakh | 20 years | 12% | ₹5,003 |
| ₹1 crore | 20 years | 12% | ₹10,006 |
| ₹1 crore | 25 years | 12% | ₹5,326 |
Starting your goal-based systematic investment plan five years earlier more than halves the required monthly SIP for the same target. If the required SIP from the calculator seems too high for your current budget, try extending the investment period first before lowering the target — time is the most powerful lever in a goal-based SIP plan.

Frequently Asked Questions
What is a goal-based SIP and how is it different from a regular SIP?
A goal-based SIP is a systematic investment plan structured around a specific financial target — such as a child's education corpus, a home down payment, or a retirement fund — rather than a fixed monthly amount chosen arbitrarily. The SIP goal calculator reverses the standard SIP formula: instead of projecting forward from a monthly amount, it calculates the monthly amount needed to reach a defined target in a defined time at an assumed return rate. This makes it easier to align your SIP contributions directly with specific life goals rather than guessing at an arbitrary investment amount.
How accurate is the reverse SIP calculator?
The reverse SIP calculator is mathematically exact for the return rate you enter — it applies the inverse of the Future Value of Annuity Due formula. The required monthly SIP it shows will produce exactly the target corpus at exactly the assumed return rate. The uncertainty is in the return rate itself, since actual mutual fund returns vary year to year. Use conservative return assumptions (10–12% for equity, 6–8% for debt) and treat the required SIP as a minimum commitment rather than a precise number. Revisiting the goal-based SIP calculator annually to recalibrate against actual portfolio performance is good practice.
What return rate should I use in the SIP goal calculator?
For goal-based SIP planning in equity mutual funds, use 10–12% for conservative-to-base case projections over horizons of 10+ years. Use 12–15% only for aggressive scenarios and cross-check your goal feasibility at the lower rate. For goals within 3–5 years, use a debt or hybrid fund rate of 7–9% since short-horizon equity is too volatile. For retirement corpus goals 20–30 years away, 12% is a defensible base case for an equity-heavy systematic investment plan, as Indian equity markets have historically delivered this over long rolling periods.
Can I set multiple SIP goals for different financial targets?
Yes. Each financial goal — child's education, home purchase, retirement, emergency fund — should ideally have its own dedicated systematic investment plan in a fund suited to its time horizon and risk profile. Use the SIP goal calculator separately for each goal with the appropriate return rate and tenure, then sum up all the required monthly SIPs to arrive at your total monthly SIP budget. Goals within 5 years should use debt or hybrid funds; goals beyond 10 years can use equity funds. Keeping goals separate also makes it easier to track progress and adjust individual SIP amounts without disturbing others.
