Quit My Job & FIRE Calculator
Estimate how long your savings could last after quitting. Enter your monthly budget, adjust assumptions and explore your balance and FIRE benchmark.
Your savings and monthly budget
Start with three numbers. Results update as you type.
Money available for living costs. Exclude property and other assets you cannot readily spend.
Include rent, food, insurance and other monthly living costs.
Fixed income you expect after quitting, excluding returns on the savings above. Enter 0 if none.
Adjust simulation assumptionsAnnual return 4% · Annual inflation 3%
Both assumptions are included in the current result. Set return to 0 to explore a scenario without investment earnings.

How long could your money last?
4 Years 2 Months
Complete months funded under your current budget, return and inflation assumptions.
Current monthly shortfall
$2,000/month
Current spending minus side income, before investment returns and inflation
A scenario estimate: income stays fixed, return and inflation follow your assumptions, and unexpected costs are excluded.
How this estimate works
Each month, savings earn the return you entered, fixed side income is added, and expenses are deducted. Annual return and inflation use compound monthly rates. Expenses rise with inflation; side income stays fixed. Returns are constant assumptions, not market forecasts. Taxes, fees, market volatility and unexpected costs are not modeled. Currency changes the symbol only; presets are examples, not local cost estimates.
Runway counts complete months that can be funded without borrowing. The chart ends at the first unfunded month. A 40+ year result means no shortfall during this simulation, not permanent financial independence.
Equivalent Expenses in 10 Years: $3,360/month · Monthly cost required to maintain today's lifestyle in 10 years
Long-term financial independence (FIRE)
View your target capital, gap and progress against the 4% benchmark.
A rough benchmark: 25 × annual expenses after fixed side income. This is separate from the monthly simulation. It is not a guaranteed withdrawal rate; future income, taxes and market conditions can change the result.
