Why Mortgage Interest Rates Matter

Your mortgage interest rate determines how much you pay in interest over time. Even a 0.5% rate change can significantly impact monthly payments and total loan costs.

How Interest Rates Affect Monthly Payments

Let’s compare how different interest rates change a 30-year, $300,000 mortgage.

Interest RateMonthly PaymentTotal Interest Paid
5.0%$1,610$279,767
5.5%$1,703$313,119
6.0%$1,799$347,514
6.5%$1,898$382,934

A 1.5% increase from 5.0% to 6.5% raises monthly payments by $288 and adds $103,167 in total interest!

How Interest Rates Impact Loan Affordability

If rates rise, homebuyers may afford less house for the same monthly budget. Here’s an example of how much home a $2,000 mortgage payment can buy at different rates:

Interest RateMax Loan Amount
5.0%$375,000
5.5%$350,000
6.0%$325,000
6.5%$300,000

A 1.5% rate increase reduces home affordability by $75,000 while keeping the same $2,000 monthly budget.
