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.

FHFA, about its own House Price Calculator: Federal Housing Finance Agency, House Price Index Datasets, HPI Calculator, copied on . The calculator of FHFA uses quarterly figures. For the states and the 100 largest metro areas it uses the purchase-only index. Its figures can differ from the figures here.

Median home value of the area, ACS 2020-2024

The American Community Survey (ACS) asks owners what their home would sell for. The table gives the middle of these answers for each area, over the 5 years 2020-2024. It is an estimate for the area. It is not the value of one home and it is not an FHFA figure.

The Census Bureau defines the value: Value is the respondent's estimate of how much the property (house and lot, mobile home and lot (if lot owned), or condominium unit) would sell for if it were for sale.

It says about the margin of error: The MOEs for published ACS estimates are provided at a 90 percent confidence level. A value of "$2,000,000 or more" is the top group, with no margin. See the glossary. The site copied these texts on .
