Accuracy matters more than looking infallible. When we find — or you report — a material error in a calculation, formula, or article, we fix it promptly and record it here so the change is transparent.
To report an error, email info@coastfirecalc.net with the page, the figure or statement in question, and what you believe is correct. Corrections to the calculator's math are prioritized.
Minor copy edits, typos, and formatting changes are not logged.
Our earlier Barista FIRE tool reduced the retirement target by permanently subtracting part-time income (target = (spending − income) × 25). That is only valid when the income lasts through retirement. For a temporary barista job, the portfolio must still reach the full retirement target. We replaced the model with two clearly separated cases — permanent income and temporary bridge — so temporary earnings are never over-counted. See the Methodology page.
We standardized the worked examples in several articles so the headline Coast FIRE figure (age 30, $40,000/yr spending, 7% nominal, 3% inflation, 4% withdrawal) consistently reads $263,555, matching the live calculator's non-rounded computation.
