A savings goal plan answers one question: how much do you need to set aside, and for how long, to reach a target amount. The calculator starts with your goal, any money you already have, the time available, and an assumed annual return. It then solves for the regular contribution that fills the remaining gap.
How much should I save each month?
First the current savings are grown to the target date. Any scheduled lump sums are grown as well. The leftover amount is the future value that recurring contributions must produce. That leftover is converted into a regular saving using the selected frequency and contribution timing.
How current savings affect your goal
Money already saved reduces the amount you still need to add. If current savings already cover the goal, required recurring saving is shown as ₹0 — never as a negative number — and any surplus is listed separately.
How expected returns affect savings goals
A higher assumed return lowers the required contribution because growth covers more of the gap. A 0% return reduces the plan to dividing the remaining amount across the contribution periods. The rate you enter is an assumption, not a forecast.
Inflation and future goals
If inflation is switched on, the target is increased first: future goal = current goal × (1 + inflation)^years. The same nominal return is then used. Inflation is not subtracted from return in the same run, which would double-count it. Real return is shown separately as (1 + nominal) / (1 + inflation) − 1.
Step-up savings and lump sums
An optional annual increase raises the contribution after each full year. Optional lump sums are added at the start of the year you choose. Both are included in the projection table rather than approximated as a flat average.
Contribution timing
End of period means the deposit is added after that period’s growth. Beginning of period means it is added first and then earns return for that period. The default is end of period.
Savings goal formula
Periodic rate i = (1 + r)^(1/m) − 1, where r is the effective annual return and m is contributions per year. Required contribution = (target − future value of current savings and lump sums) / future value of a unit contribution schedule. With 0% return this becomes (target − current savings) / number of periods.
How to use the calculator
Use Save for a Goal when you know the target and date. Use When Will I Reach My Goal? when you know how much you can save. Use How Much Will I Have? to project a contribution plan without a fixed target.
