How It Works
This fed rate mortgage impact calculator uses established formulas to provide accurate results.
The basic rule:
- Mortgage Payment = Loan x (r(1+r)^n) / ((1+r)^n - 1)
- Fed-to-Mortgage passthrough rate: approximately 65%
- Buying Power = Loan amount at new rate that produces the same monthly payment
- Lifetime Impact = Monthly Difference x Total Payments

Frequently Asked Questions
How does the Fed rate affect mortgage rates?
The Fed funds rate does not directly set mortgage rates, but it strongly influences them. Mortgage rates typically move 50-75% of a Fed rate change, with a lag of days to weeks. A 0.25% Fed cut usually translates to a 0.15-0.20% mortgage rate decline.
Should I wait for a rate cut to buy a house?
Not necessarily. Rate cuts often increase buyer demand, driving up home prices. Buying at a higher rate and refinancing after a cut can be smarter than competing in a low-rate market. The saying goes: marry the house, date the rate.
How much does a 1% rate change affect my payment?
On a $320,000 loan, each 1% rate change moves the monthly payment by roughly $200-220. Over 30 years, that is $72,000-$80,000 in total interest. Even 0.25% matters — it is about $50/month or $18,000 over the life of a loan.
When will mortgage rates go down?
Mortgage rates depend on inflation, Fed policy, and bond markets. Rates tend to fall when inflation is controlled and the economy slows. Most forecasters expect gradual declines as inflation normalizes, but rates below 5% likely require a recession.
