$5 MORTGAGE
How much would you pay back over 30 years for every $5 borrowed?
$5 is used as a fixed reference to isolate the impact of mortgage rates on borrowing costs. Using historical US 30-year fixed mortgage rates, this page shows how much you would have paid back over 30 years on a constant $5 loan. The amount borrowed never changes. Only the rate does.

Source: Freddie Mac Primary Mortgage Market Survey — 30-year fixed-rate mortgage average, weekly, via FRED (series MORTGAGE30US). Annual figures are the arithmetic mean of all weekly observations within each calendar year; 2026 reflects partial-year data and is revised as new readings arrive.
Each point shows the total amount repaid on a $5, 30-year fixed mortgage using that year's historical US mortgage rate. The $5 principal stays constant, so changes in the result come entirely from changes in mortgage rates.
Monthly payments are calculated using the standard fixed-rate mortgage formula and multiplied by 360 payments to determine the total amount paid over the full 30-year term.
