v1.15.0 — Site quality and transparency update
July 2026
Added
- New "How Our Calculators Work" methodology page documenting the assumptions, formulas, and limits behind every tool, with named sources including Bengen (1994) and the Trinity study.
- New guide: "FIRE Number Worked Example" that follows one household through the full arithmetic, a year-by-year projection, and a withdrawal-rate and return sensitivity table.
- New guide: "Choosing a Safe Withdrawal Rate" covering where the 4% rule came from, sequence-of-returns risk with a worked illustration, and why early retirees often use 3.25-3.75%.
- Expanded About page describing who builds Fire-Calc, how the calculators are tested, our editorial standards, and our advertising-only, no-affiliate independence.
Improved
- Debt payoff engine now rolls each freed-up minimum payment into the next target debt, so avalanche and snowball comparisons reflect how a focused strategy actually accelerates.
- Accessibility improvements across content and calculator pages.
Fixed
- Debt payoff calculator now warns when an entered payment is too small to outpace interest, meaning the balance would never be paid off.
