Freedom Calcs
Free Coast FIRE calculator for retirement savings milestones
About Freedom Calcs
Freedom Calcs is a free set of retirement calculators built for people pursuing financial independence. Its flagship Coast FIRE calculator estimates how much you need invested today to grow toward a later retirement target without further contributions, and it shows the age at which that milestone is reached under your chosen assumptions.
Users enter their current age, retirement age, invested assets, annual retirement spending and optional monthly contributions. Results are shown in today's dollars, with a projection chart and a comparison of contribution plans such as continuing, halving or stopping contributions. The site also explains the underlying formulas and lets readers adjust return, inflation and withdrawal assumptions.
The tool runs in the browser and says it does not require an account or upload financial data. The site positions its results as educational estimates rather than personalized financial advice, and it includes companion calculators for other FIRE variants.
