FIRE Calculator Guide: Estimate a Retirement Target
Financial independence planning begins with future spending, not a fashionable corpus number.
From spending to corpus
QuickCalcy inflates current monthly expenses until the planned retirement year, converts them to annual spending and divides by an assumed withdrawal rate. Lower withdrawal rates produce larger targets.
Build several scenarios
Separate essential and flexible expenses, add future health or housing obligations, and test multiple inflation and withdrawal rates. Costs that end before retirement should not remain in the input.
Use the target responsibly
Compare the corpus with existing assets and projected contributions, then review it periodically. A retirement plan may also require insurance, near-term cash reserves and an asset-allocation strategy.
Mistakes and limitations
- No withdrawal rate guarantees sustainability.
- The simple target does not model longevity or return sequence.
- Taxes and pension income need separate treatment.
The result is a starting point for deeper retirement planning.
