Mutual Fund Goal Calculator

You know what you need and when. This works backwards to the monthly SIP that gets you there — taking into account anything you have already saved.

How to use this calculator

  1. Enter goal amount — What you need, in future rupees.
  2. Enter years to the goal
  3. Enter expected annual return
  4. Enter already saved — Existing investments earmarked for this goal. (optional — leave it as it is if it does not apply)
  5. Read the result — it updates as you type.

The formula used

M = (Goal − Existing×(1+i)n) × i ÷ [ ((1 + i)n − 1) × (1 + i) ]

M
Monthly SIP required
i
Monthly return = annual ÷ 12 ÷ 100
n
Number of months until the goal

This is the standard SIP formula rearranged to solve for the instalment. Existing savings are first grown to the goal date and subtracted, so you only fund the gap.

Worked example

You need ₹20,00,000 in 8 years and expect 12%, with nothing saved yet.

  • Months (n)96
  • Monthly rate (i)0.01
  1. (1.01)96 = 2.59927
  2. (2.59927 − 1) ÷ 0.01 × 1.01 = 161.526
  3. ₹20,00,000 ÷ 161.526 = ₹12,382 a month

You would invest about ₹11.9 lakh of your own money; the remaining ₹8.1 lakh is expected growth.

Planning backwards from a goal

Most people start with "how much will my SIP grow to?" A goal calculator flips that: you state the target and the deadline, and it tells you what to invest.

Use future rupees, not today's

If your goal is a ₹20 lakh car in eight years, that car will not cost ₹20 lakh then. Put today's price through the Inflation Calculator first, and use the inflated figure as your goal here.

Match the return to the deadline

  • Under 3 years — assume 6–7% and use debt funds or deposits. Equity can fall right when you need the money.
  • 3 to 7 years — 8–10% with a balanced mix.
  • Over 7 years — 10–12% with an equity-heavy portfolio is a common assumption.

If the number looks impossible

Three levers: give the goal more time, reduce the target, or increase the SIP each year instead of keeping it flat — see the Step-Up SIP Calculator.

Tips and common mistakes

Getting more out of it

  • Inflate the goal first. A ₹20 lakh car today will not cost ₹20 lakh in eight years.
  • Match the assumed return to the deadline — a three-year goal should not be planned at equity rates.

Mistakes to avoid

  • Entering today's price as a future goal, which guarantees a shortfall.
  • Counting retirement savings towards a different goal, so the same money is spent twice on paper.
  • Setting the plan once and never revisiting it. Review the figure yearly and adjust the instalment.

Frequently asked questions

Should I enter today's cost or the future cost?

The future cost. Inflate today's price first — a goal that costs ₹10 lakh today will cost about ₹16 lakh in eight years at 6% inflation.

What if I cannot invest the amount shown?

Extend the deadline, lower the target, or start smaller and step the SIP up each year. Even a partially funded goal beats an unfunded one.

Is the return guaranteed?

No. If markets underperform your assumption, you will fall short. Review the goal once a year and adjust the instalment rather than assuming the original plan still holds.

Can I include my existing PPF or EPF?

Only if that money is genuinely earmarked for this goal and will be available on the date you need it. Retirement money usually should not be counted towards other goals.
