Mortgage Rate Data: 30-Year and 15-Year Fixed
Weekly national average mortgage rates from the Freddie Mac Primary Mortgage Market Survey, charted over the trailing 24 months with the full weekly table. Rates shape affordability and therefore demand in every housing market. Every figure is drawn from a public source and stamped with its reporting period. No estimates appear on this page.
Key figures
Plate 1 30-year and 15-year fixed, trailing 24 months
Weekly averages from thousands of loan applications submitted to Freddie Mac by lenders nationwide. The 15-year rate typically runs below the 30-year rate because the shorter term carries less duration risk.
Plate 2 Latest readings
The most recent weekly readings, the same week one year earlier, and the current spread between the two terms. The spread figure is computed on this page from the two source values and is labeled as computed.
Plate 3 Weekly readings, full table
Every weekly observation in the charted window, newest first. Values are exactly as published by the source.
Methodology and sources
Every figure on this page is taken directly from a public source and is stamped with its reporting period. Rate values are reproduced exactly as published. The only computed value on this page is the spread between the 30-year and 15-year readings, which is labeled as computed wherever it appears. Nothing on this page is estimated, interpolated, or modeled by the publisher of this page.
Freddie Mac publishes the Primary Mortgage Market Survey weekly. Survey methodology changed in November 2022 to a loan-application basis. Rates move constantly between weekly readings. Confirm current values against the linked sources before relying on any figure for a transaction decision.
