Why Release Transparency Matters

Version notes make it easier to understand output differences and keep collaborative planning conversations aligned.

When to Revisit Saved Scenarios

If assumptions, formulas, or calculator UX changed, rerun important scenarios before relying on older exports.

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.
  • Removed unused placeholder ad slots from page templates.

v1.14.0 — New Equity Calculator

June 1, 2026

Added

  • New Equity Calculator for modeling your whole equity stack in one place — RSUs, stock options (ISO/NSO), ESPP, restricted stock (RSAs), and SAR/phantom/performance (PSU) grants.
  • Plots vested value, unvested value, and after-tax-if-liquidated value year by year, with a per-grant breakdown plus CSV, PDF, and shareable-link export.

v1.13.0 — First-time homebuyer guide refinements

May 3, 2026

Improved

  • Expanded the affordability table up to $250,000 of gross annual income for at-a-glance reference.
  • Added a "reality check" callout distinguishing the 28% lender ceiling from a more conservative ~20%-of-gross personal-finance target.
  • Clarified that income figures in the affordability table are gross (pre-tax).

Fixed

  • Corrected approximate home price ranges to reflect actual PITI math at 7% / 30-year fixed / 20% down with realistic property tax and insurance assumptions.
  • Footnote inside the affordability table now has proper padding instead of butting up against the container edge.

v1.12.0 — Job Offer Comparison calculator

April 27, 2026

Added

  • New Job Offer Comparison calculator with tax-aware equity modeling, RSU appreciation, and a labeled breakeven chart.

Improved

  • Wide layout for the Job Offer calculator with a "pool-held" column for clearer equity comparison.
  • Clarified gross vs. net labels in the Advanced FIRE drawdown flow.

Fixed

  • Advanced drawdown cascade ordering for capped 401(k) and overflow handling.
  • RSU appreciation calculation in the Job Offer engine, with regression tests added and the offer count capped at 2.

v1.10.0 — Drawdown calculation correctness fix

March 28, 2026

Fixed

  • Top-level resources and guides are available as first-class in-app content routes.

Fixed

  • Advanced withdrawal cascade now preserves withdrawal targets when 401(k) assets remain.
