A browser-based retirement planning calculator and interpretation guide.
The site helps people estimate retirement readiness using explicit assumptions and scenario comparisons.
What we do
- Estimate FIRE number, projected portfolio, and success probability.
- Model cash-flow and inflation interactions in one workflow.
- Store scenario comparisons for your own planning checks.
What we do not do
- Give personalized financial, legal, or tax advice.
- Guarantee any retirement date or account outcome.
- Replace professional review of taxes, benefits, or estate needs.
Assumptions drive every result. If one assumption changes, results can change materially.
How to interpret calculator outputs
- Use FIRE number, projected portfolio, and success rate together.
- Run conservative and stress scenarios before making financial commitments.
- Consult a qualified professional for final decisions.
