How we work it out

Targets equal yearly spending divided by your withdrawal rate; Barista FIRE subtracts part-time income first. Real annual return is (1 + expected return) ÷ (1 + inflation) − 1, converted to a monthly rate. Contributions are added at month-end and the actual rupee amount increases by 0% after each completed year. Each contribution is adjusted for inflation to show its value in today’s money. A 0% step-up keeps the actual monthly payment fixed. Coast FIRE finds when growth alone can meet your regular target by retirement. Projections stop at age 89; taxes and fees are excluded. Returns are assumptions, not guarantees.

What’s the difference?

FIRE means Financial Independence, Retire Early: having enough invested that withdrawals cover your spending. The flavours differ in how much you plan to spend and whether you keep earning.

How to use the FIRE calculator

FIRE means Financial Independence, Retire Early. This planner estimates the investment pot needed to cover your spending, and when you could reach it under your own saving, return and inflation assumptions. Amounts are shown in rupees using Indian numbering.

  1. Enter your age, retirement age, current retirement investments, monthly contribution and annual contribution step-up.
  2. Add your annual spending and adjust the Lean, Fat and part-time income assumptions.
  3. Choose expected return, inflation and withdrawal rate, then compare all five FIRE paths.

The calculation

FIRE number=annual spendingwithdrawal rate rreal=1+expected return1+inflation−1 rmonth=1+rreal112−1
For example, ₹6,00,000 per year ÷ 0.04 = ₹1,50,00,000. Growth is compounded monthly after adjusting for inflation; contributions are added at each month’s end.

Common questions

What is the difference between Lean, Fat, Coast and Barista FIRE?

Lean FIRE uses a smaller spending budget; Fat FIRE uses a larger one. Coast FIRE finds when your current pot can grow to your retirement target without further contributions. Barista FIRE reduces the spending your investments must cover by your expected part-time income.

Does this FIRE calculator account for inflation?

Yes. The real annual return is (1 + expected return) divided by (1 + inflation), minus 1. The actual rupee contribution increases by the chosen step-up after each completed year, then each payment is adjusted for inflation to express results in today’s money. A 0% step-up keeps the actual monthly payment fixed.

Is the calculated retirement age guaranteed?

No. It is a projection using constant assumptions. Actual returns, spending, inflation, taxes and fees can change the outcome. A target outside the model’s horizon is shown as not reached.
