Goal-Based Investment Planner
Plan how much to invest monthly or yearlyto reach a target corpus. Enter your goal (with optional inflation for today's cost), money you already have, expected return, and years to the goal—see the shortfall and the systematic investment amount that closes the gap.
Enter what the goal costs today; we inflate it to the goal date using your inflation rate.
Future goal value ≈ today's cost × (1 + inflation)years. Many planners use roughly 5–7% for broad long-run estimates.
Grows at your expected return until the goal date (annual compounding).
We use the same beginning-of-period convention as our SIP calculator for monthly mode.

Why goal-based investment planning matters
Most people save “what is left” after expenses. Goal-based planning flips that: you fix the future need—education, home, wedding, retirement—estimate when you need the money, and then solve for how much to invest regularly at an assumed return. That turns a vague wish into a number you can track in your budget, similar in spirit to classic SIP goal planning and target corpus workflows used by financial planners.
Inflation and today's cost of the goal
Long-term goals rarely stay at today's price. Education, healthcare, and many services rise faster than general inflation. When you choose “today's cost + inflation,” this planner compounds your goal amount at your stated annual inflation to get a future value of the goal. If you already know the rupee amount you want on the goal date, switch to “target at goal date” and skip that step.
Existing corpus and the shortfall
Money already invested for the goal is projected to the goal date using the same expected annual return. The shortfall is what is left to build with new monthly or yearly contributions. If the projected corpus meets or exceeds the goal, the planner shows no further instalment—your assumptions say you are on track.
How this relates to SIP and step-up plans
The periodic amount here is a planning anchor. In real life you might use mutual fund SIPs, EPF, NPS, or a mix. If your income rises over time, a step-up SIP can reduce the starting instalment versus a flat SIP. For pure wealth projection from a fixed payment, see the SIP calculator. For inflation on costs alone, use the inflation calculator.
Formulas used (summary)
- Future goal from today's cost: Future goal ≈ Today's cost × (1 + inflation)n (annual inflation, n years).
- Future value of existing lump sum: FV = Present × (1 + return)n.
- Shortfall: max(0, Future goal − FV of existing).
- Periodic investment (annuity due): Payment = Shortfall ÷ [((1 + r)t − 1) / r × (1 + r)] with r and t matching monthly or yearly periods and your expected return.
Returns are not guaranteed; taxes and charges are not modeled. Use conservative assumptions and review your plan at least yearly.
Benefits of using this planner
- One number to aim for: A clear monthly or yearly contribution toward a defined corpus.
- Inflation-aware goals: Optional inflation on today's cost for long horizons.
- Credit for savings already done: Existing investments reduce the required instalment.
- Frequency choice: Compare monthly versus yearly contribution styles.
Frequently asked questions
What is a goal-based investment plan?
A goal-based investment plan means deciding how much money you need by a future date—such as education, home purchase, or retirement—and working backwards to set monthly or yearly contributions and choose investments aligned with that timeline and risk.
How does this calculator find the monthly investment needed?
It first finds the corpus you need at the goal date—either the amount you enter for that date, or today's cost inflated to the goal date. It subtracts the future value of any lump sum you already have invested at your expected return. The remainder is filled using an annuity formula consistent with beginning-of-period monthly or yearly investments at the same expected return.
What is the difference between goal in today's rupees and target at goal date?
Today's rupees means the cost of the goal if you had to pay today; the calculator inflates that amount by your assumed annual inflation over the years until the goal. Target at goal date means you already know the rupee amount you want on the goal date, so no inflation step is applied to the goal itself.
Why include existing investments?
Money you have already set aside for the goal compounds until the goal date. The calculator estimates its future value at your expected return and only asks for new contributions to cover any shortfall.
What expected return should I use?
Use a rate that matches your planned asset mix and time horizon, not past performance of a single fund. Equity-heavy long-term plans often use higher assumed returns than short-term debt-heavy plans. Treat the result as an estimate and review regularly.
Is the monthly amount the same as a mutual fund SIP?
The math is the same family as a systematic investment plan: regular contributions invested for growth. Actual mutual fund SIPs have fees, market volatility, and tax effects; this tool uses fixed return assumptions for planning.
Can I use this for retirement planning?
Yes. Enter your target retirement corpus or inflate today's annual expense into a future corpus need, add existing retirement savings, and see how much more to invest each month or year at your assumed return.
Is the ZeroKhata goal-based investment planner free?
Yes. It is free to use with no sign-up or payment. You can change inputs as many times as you like.
