Front-end and back-end ratios are planning limits, not a loan approval.
Two ratios, one payment
The front-end ratio caps housing as a share of gross income. The back-end ratio caps housing plus the debts you already pay. The tighter one wins. Tax and insurance have to come out of that payment before a loan amount is solved.
Twenty-eight and thirty-six are the familiar defaults. A lender, or your own comfort, may use different numbers. The house affordability calculator leaves both ratios editable so the price is yours, not a slogan.

How to read this note
The 28/36 Housing Rule Is a Ceiling You Can Edit is one question, not a plan for every account you own. The opening claim is this: Front-end and back-end ratios are planning limits, not a loan approval. 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. Two ratios, one payment. 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
The 28/36 Housing Rule Is a Ceiling You Can Edit 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
The 28/36 Housing Rule Is a Ceiling You Can Edit uses a specific illustration so the relationship is easy to see. The category is Home & Mortgage. The tools sitting next to the note are House Affordability Calculator, Debt-to-Income 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. Front-end and back-end ratios are planning limits, not a loan approval.
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.
