Understanding FIRE Calculations

Our calculator uses industry-standard financial formulas to provide accurate estimates. Results are based on the inputs you provide and standard financial assumptions. While our calculations are precise, real-world results may vary based on fees, taxes, and other factors.

Use these results as a starting point for your financial planning. For major financial decisions, consult with a qualified financial advisor who can account for your complete financial picture.

Tips for Better Financial Planning

  • Run multiple scenarios — try different values to understand the range of outcomes.
  • Be conservative with projections — use lower return rates and higher expense estimates.
  • Review annually — your financial situation changes; recalculate regularly.
  • Account for inflation — a dollar today will be worth less in 20 years.
  • Use this as a starting point — then work with a financial advisor for personalized advice.
