How Interest Rates Affect Your Money
When the Federal Reserve raises or lowers its target rate, the effects ripple through the entire economy. Mortgage rates, auto loan rates, credit card APRs, and savings account yields all respond, though not always at the same pace or magnitude.
For borrowers, even a small rate change can significantly affect total cost over the life of a loan. On a $350,000 mortgage, a 1 percentage point increase typically adds $200+ to monthly payments and tens of thousands in total interest. For savers, higher rates mean better returns on deposits.
The current 30-year fixed mortgage rate is 6.46%, sourced from FRED. Rates change frequently based on Federal Reserve policy, inflation expectations, and bond market conditions.
