ProjectedPath to FIRE
ChartFormula usedFIRE number plus reverse target-age savings solver
The path to FIRE is simulated year by year by compounding current savings, adding annual savings, and increasing contributions with the inflation-linked growth assumption. Goal mode keeps the same FIRE number and solves for the savings needed to reach it by a chosen age.
AssumptionsBase scenario
- Annual expenses are the main driver of the FIRE target and are assumed to be representative of long-term lifestyle costs.
- Savings contributions continue consistently each year and grow in line with the chosen inflation-linked assumption.
- Scenario bands change return, inflation, and withdrawal assumptions but do not alter the income or expense base directly.
- The withdrawal rule remains stable for the full retirement period.
- Uses the current savings, return, inflation, and withdrawal assumptions.
Limits and freshnessUpdated 2026-04-03
- The 4% rule and similar withdrawal heuristics are simplified rules of thumb, not guarantees.
- The model does not explicitly include taxes, healthcare shocks, or varying spending in early vs late retirement.
- Portfolio sequence risk is not modeled, so early retirement market crashes may be understated.
Check the result under a lower withdrawal rate or lower return assumption to see how much safety margin the current plan has.

About FIRE Calculator
Guide1What is FIRE (Financial Independence, Retire Early)?
FIRE stands for Financial Independence, Retire Early. It is a movement and financial strategy focused on aggressive saving and investing to accumulate enough wealth that the returns from your investments can cover your living expenses indefinitely, allowing you to retire much earlier than the traditional age of 60.
The core idea is to save 50-70% of your income, invest aggressively, and reach a corpus that sustains your lifestyle through passive income. In the Indian context, where the cost of living is relatively lower, FIRE can be achieved with a more moderate corpus than in Western countries.
2The FIRE Number and 25x Rule
Your FIRE number is the corpus you need to achieve financial independence. The most common method to calculate it is:
FIRE Number = Annual Expenses × 25
This is based on the 4% safe withdrawal rate — the idea that you can withdraw 4% of your corpus annually (adjusted for inflation) without running out of money over a 30-40 year retirement. In India, considering higher inflation, some experts recommend a 3-3.5% withdrawal rate, leading to a 28-33x multiplier.
3Types of FIRE
- Lean FIRE: Achieving financial independence with a minimalist lifestyle and lower expenses
- Fat FIRE: Accumulating a larger corpus to maintain a comfortable, higher-spending lifestyle
- Barista FIRE: Having enough investments to semi-retire and work part-time for supplementary income
- Coast FIRE: Having enough invested that compounding alone will grow it to a full FIRE number by traditional retirement age
