Divide spending by the rate to get a nest egg. Then argue with the rate.
Spending sets the target
A portfolio that supports $60,000 a year at 4% is $1.5 million. That is the whole trick. The research behind 4% looked at historical US portfolios over roughly 30-year retirements. A longer retirement, a lower stock share, or high fees can argue for a smaller rate.
The FIRE calculator turns spending and a rate into a target, then projects whether your current savings and monthly investing arrive. Include taxes in the spending number if the withdrawals will be taxed.
Run the same question with your figures

How to read this note
A 4 Percent Withdrawal Is a Starting Point, Not a Contract is one question, not a plan for every account you own. The opening claim is this: Divide spending by the rate to get a nest egg. Then argue with the rate. The sections above stay on that claim. They use a worked figure so the relationship is visible. A worked figure is not a prediction that your loan, your fund, or your tax year will match it.
Read the headings in order. Spending sets the target. If a sentence names a calculator, that link is the place to change the inputs. If a sentence names a limit, the limit is the one published for the year written on the page, which is 2026 where this desk cites a retirement or tax figure.
A senior reading of a finance page looks for three things. The formula should match the labels. The example should be reproducible on the calculator. The page should say what it leaves out. This note tries to do those three. It does not tell you to borrow, to sell, to contribute the maximum, or to file a return from the illustration.
What the note leaves out
A 4 Percent Withdrawal Is a Starting Point, Not a Contract ignores facts it does not mention. Fees, state tax, a credit score, an employer match you have not typed, and a market that refuses to pay a flat rate are all outside the paragraph. When one of those facts is the actual question, open the calculator that asks for it or read the disclaimer before you move money.
Published 25 Oct 2026. If a public figure in the note is later revised by the IRS, a lender, or a data source, the calculator page and the methodology are the places this desk updates. The note does not store what you type, and it is not a message from a broker or a tax preparer.
Before you treat the example as yours
A 4 Percent Withdrawal Is a Starting Point, Not a Contract uses a specific illustration so the relationship is easy to see. The category is Retirement. The tools sitting next to the note are FIRE Calculator, Retirement Calculator. Open one of them, replace the example, and press Calculate if the decision in front of you depends on your balance, your rate, or your income. The article does not update itself when those facts change.
A careful reading checks three matches. The heading should be the question you have. The worked number should use inputs you can point to. The omitted items, named above, should be irrelevant or added back in a field. If any of the three fails, do not stretch the conclusion. Divide spending by the rate to get a nest egg. Then argue with the rate.
Keep the note and the calculator apart in your notes. The note explains why the pieces move. The calculator shows how far they move once you type them. Publishing date 25 Oct 2026 is the version of the explanation you are reading. Public limits can change after that date, and the methodology is where this desk records the figures it is willing to stand behind.
