How this is calculated

Find C such that Savings × (1 + r/12)^m + Σₖ C × (1 + s)^⌊k/12⌋ × (1 + r/12)^(m − k) = Target

C
Monthly saving in year 1
s
Yearly step-up
m
Months until retirement

The planner works backwards from your target: first it grows the savings you already have, then finds the monthly saving that makes up the rest by your retirement age. With a step-up, the first-year amount is smaller because later contributions are larger.

Assumptions & sources

  • Savings grow monthly at the pre-retirement return ÷ 12, with contributions at the start of each month; any step-up applies every 12 months.
  • Returns and inflation are constant averages — real markets vary year to year, and a bad sequence early in retirement matters most.
  • Taxes on withdrawals and investment gains are not deducted.
  • Solved numerically by bisection to within a rupee.

Common questions

Where does the target corpus come from?

From your expected retirement expenses, inflation and how long retirement lasts. The Retirement Corpus Planner calculates it.

Is a step-up realistic?

If your income rises over time, yes. Raising your saving by 5–10 % a year makes a big difference to the starting amount needed.
