What is a goal planning calculator?
A goal planning calculator, also called a goal-based SIP calculator or financial goal planner, works backward from a target amount to find the monthly SIP or lumpsum needed today to reach it.
Most SIP calculators start from a monthly amount and project what it grows to. Goal planning reverses the question. You already know the number you need, whether it is a child's college fee, a home down payment, or a retirement corpus.
The calculator finds the monthly SIP, or a one-time lumpsum, that reaches that number given an expected rate of return and a time horizon.
The goal planning formula
This calculator solves the SIP annuity formula and the present value formula for the amount unknown, after netting off any existing savings.
Monthly SIP = Remaining Target / [((1 + i)^n minus 1) / i × (1 + i)]Lumpsum = Remaining Target / (1 + r)^years| Variable | Meaning |
|---|---|
| Remaining Target | The goal amount minus the future value of any existing savings |
| i | Monthly return rate: (1 + annual rate)^(1/12) minus 1 |
| n | Number of months in the time horizon |
| r | Annual return rate as a decimal |
A Rs 1 crore goal in 10 years at 12 percent needs a monthly SIP of roughly Rs 44,600. At 8 percent, the same goal needs about Rs 55,200 a month. The return rate is the single most consequential input in any goal plan.
How existing savings reduce your required SIP
Most goal calculators assume you start from zero, which overstates the SIP anyone with existing savings actually needs. This calculator projects your existing savings forward at the same assumed return and subtracts that future value from the goal first.
Take a Rs 50 lakh goal in 10 years at 10 percent, with Rs 5 lakh already saved. That Rs 5 lakh grows to roughly Rs 12.97 lakh on its own over 10 years, leaving a remaining target of about Rs 37 lakh.
The monthly SIP for that remaining Rs 37 lakh works out to roughly Rs 18,400, compared with about Rs 24,800 a month if the existing savings were ignored entirely.
Monthly SIP needed for common goal amounts
These figures assume no existing savings and a 12 percent annual return, a standard equity mutual fund assumption used across Indian financial planning.
| Goal Amount | 5 Years | 10 Years | 15 Years | 20 Years |
|---|---|---|---|---|
| Rs 10 lakh | Rs 12,330 | Rs 4,460 | Rs 2,100 | Rs 1,090 |
| Rs 25 lakh | Rs 30,800 | Rs 11,150 | Rs 5,250 | Rs 2,720 |
| Rs 50 lakh | Rs 61,650 | Rs 22,300 | Rs 10,500 | Rs 5,440 |
| Rs 1 crore | Rs 1,23,300 | Rs 44,600 | Rs 21,000 | Rs 10,900 |
Use the calculator above for your own target, return assumption, and time horizon. These figures are rounded and meant only to show how the required SIP shrinks as the time horizon extends.
Choosing the right return rate for your goal
The return assumption should match the asset class you actually plan to invest in, not the highest number you have seen quoted.
| Asset Class | Typical Long-Term Return | Suited For |
|---|---|---|
| Fixed deposit / PPF | 6 to 7.1% | Goals under 3 years, capital protection |
| Debt mutual funds | 6 to 8% | Goals 3 to 5 years away |
| Balanced / hybrid funds | 8 to 10% | Goals 5 to 8 years away |
| Large-cap equity funds | 10 to 12% | Goals 8 years or more away |
| Diversified / flexicap equity | 12 to 15% | Long-term goals 10 years or more away |
A goal less than three years away should not assume equity returns, since a market downturn right before you need the money can permanently impair the plan. Shorten the assumed return as the goal date approaches.

Goal planning for common life goals in India
Every goal needs its own target, since inflation affects each cost differently and the time horizon changes how much risk you can afford to take.
| Goal | Typical Horizon | Suggested Return Assumption |
|---|---|---|
| Emergency fund | 0 to 1 year | 4 to 6% (liquid fund / savings account) |
| Wedding | 2 to 5 years | 6 to 9% (debt-to-hybrid mix) |
| Home down payment | 3 to 7 years | 8 to 10% (hybrid to equity mix) |
| Child's education | 10 to 18 years | 10 to 12% (equity, de-risked near the goal) |
| Retirement corpus | 15 to 30 years | 10 to 12% (equity, de-risked near retirement) |
For more than one goal, run this calculator once per goal with its own target, horizon, and return assumption, then add the resulting monthly SIP figures for your combined monthly commitment.

How to use this goal planning calculator
Choose the Monthly SIP tab or the Lumpsum tab depending on how you plan to invest.
- Target Amount: the corpus you need at the end of the horizon, in today's rupees or already inflation-adjusted.
- Expected Return: the annual return you expect from the asset class you plan to invest in.
- Time Horizon: the number of years until you need the money. Use the preset pills to jump to common durations.
- Existing Savings: money already set aside for this goal. Leave at zero if starting fresh.
The result, donut chart, and progress bar update instantly as any input changes. Expand the Year-by-Year Goal Progress table under the Monthly SIP tab to see how the corpus builds each year, and switch currency using the selector in the input panel if planning from outside India.
