Retirement
FIRE Calculator
Estimate when work may become optional based on savings, returns, and desired annual spending.
Your portfolio crosses the FIRE line in 2044 if these assumptions hold.
How it works
The calculation, without the clutter
WealthyNest uses reusable finance formulas for compounding, withdrawal targets, and cash-flow projections.
Each tool pairs those formulas with calculator-specific assumptions and a concise summary.
Where this tool is most useful
FIRE Calculator is most useful when you have a clear target lifestyle and want to see whether your current savings plan supports it.
Key assumptions
What to sanity-check
- Returns are smoothed estimates and do not reflect real-world market volatility.
- All figures are in today's dollars unless the calculator is explicitly modeling inflation adjustments.
- This tool is intended for planning, education, and comparison rather than certainty.

Common questions
Are these outputs guarantees?
No. They are planning estimates based on your assumptions and should be updated as markets, taxes, and spending change.
Do these calculators replace professional advice?
No. They are a strong planning starting point, but tax, legal, and investment decisions should be reviewed with a qualified professional when appropriate.
How often should I revisit my inputs?
A good rule is to revisit assumptions after major income, spending, family, tax, or market changes and at least a few times per year.
Why do the optimistic and conservative scenarios matter?
They help you see how sensitive the result is to assumptions instead of anchoring on one exact output.
