How to read this note
Real Return Is Not Quite Nominal Minus Inflation is one question, not a plan for every account you own. The opening claim is this: The Fisher equation divides. Subtracting is close and slightly generous. The sections above stay on that claim. They use a worked figure so the relationship is visible.

Read the headings in order. Divide, then subtract one. 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

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.
