About the publisher
Coast FIRE Calculator publishes free calculators and educational guides that show their assumptions, formulas and limits. The site is built around one practical question: how much would need to be invested today for compound growth to support a future retirement target?
Our mission
The main calculator estimates a FIRE target, present-day Coast FIRE number, funding gap or surplus and projected Coast date. Related tools explore contributions, career changes, couples, taxes, benefits, healthcare and account access.
Explore all tools →Core formulas are documented publicly. Examples should come from the same calculation engine used on the site. Research pages identify sources and explain whether a source informs a range, a rule or only historical context.
Read the methodology →Coast FIRE Calculator is the organizational publisher and editorial team. We do not claim a certified financial-planner review or attach a fictional expert identity. Review dates describe an internal content and implementation check.
Meet the editorial team →A deterministic projection cannot predict returns, inflation, tax law, healthcare costs or personal behavior. It also cannot choose an asset allocation or retirement date for you. Use scenarios to ask better questions, then verify decisions with qualified professionals.
