Each figure is the change of the FHFA annual all-transactions index, from the year that you pick to 2025. It is a change for the area. It is not the change in the value of your home, and it does not use the price that you paid.

The average for each year is a compounded annual change. The guide to values explains more.

When using the FHFA House Price Calculator, please note that it does not project the actual value of any particular house.

For the states and the 100 largest metro areas it uses the purchase-only index. Its figures can differ from the figures here.
