When Can I Quit? Calculator
Explore the time to a savings target using an adjustable savings rate and return assumption. A planning scenario, not a safe-to-quit date.
Quick answer: A savings milestone is not permission to quit. Model an expense reserve, then test lower returns, higher expenses and delayed income. Use your own numbers below.
The six-month and 25× targets are illustrative. Constant returns omit volatility, fees, inflation and withdrawal risk; reaching 25× spending does not guarantee lifelong income.
When to use this tool:
- Career transition planning
- FIRE journey tracking
- Assessing monthly savings impact
How it's Calculated
- Monthly contribution = annual salary / 12 × (1 − effective deduction rate / 100) × savings rate / 100 + monthly side income saved.
- Targets = monthly expenses × 6 and monthly expenses × 12 × 25.
- Savings compound monthly at entered annual return / 12, with contributions at month end.
Key Assumptions
Defaults are example inputs. See methodology and corrections for how to check results, or report an issue.
- The deduction percentage is your estimate, not a tax calculation.
- All entered side income is saved after expenses and taxes.
- Return and spending stay constant. Use zero return to inspect a cash-only scenario.
Actionable Insights
- At zero return, $10,000 savings and $1,000 monthly contributions reach an $18,000 target in eight months.
- Lower spending reduces the target, but this calculator only changes contributions when you change the savings inputs.
Frequently Asked Questions
No. It projects an arithmetic milestone, not employment prospects or personal safety.
No. Use zero and alternative assumptions to see sensitivity.
It is an illustrative long-term target, not a promise of sustainable withdrawals.
Your entered deduction percentage reduces gross salary before applying the savings rate.
This model uses it while accumulating savings. Current runway assumes no ongoing income.
Use expected expenses and update contribution assumptions separately.
A cash-only example
With $10,000 already saved and monthly expenses of $3,000, the six-month reserve is $18,000. Saving $1,000 each month at zero return takes eight months to close the $8,000 gap. A $500 unexpected bill increases that gap; a delayed paycheck can change the timing.
Keep the two targets separate
A short career break and long-term retirement have different requirements. The 25× spending output is a scenario for accumulation, not a withdrawal simulation. It does not model investment losses, sequence of returns, future taxes or changing family costs.
Use the transition checklist to check insurance and one-time expenses. If a job loss has already happened, the layoff calculator separates benefit timing from available savings.
