$5 MORTGAGE

How much would you pay back over 30 years for every $5 borrowed?

The goal of this page is to show how even a small change in the mortgage rate can make a huge difference in the total cost of a loan over 30 years. $5 is used as a fixed reference to show how much you would pay back for every $5 taken out in a mortgage. Using historical US 30-year fixed mortgage rates, the chart shows how much that $5 loan would have cost over 30 years. 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.
