How much interest does a Washington homeowner pay over 30 years?
On a $417,000 loan at 6.8% for 30 years, a Washington borrower pays $561,670 in total interest — on top of the $417,000 principal. Total amount repaid: $978,670. Choosing a 15-year term instead saves $312,374 in interest (total interest: $249,296) but raises the monthly payment to $3,702.
How does paying extra principal reduce a Washington mortgage?
On a $417,000 mortgage at 6.8% for 30 years ($2,719/month), adding $200/month extra reduces the loan term by approximately 6 years and saves roughly $75,000–$80,000 in interest depending on when you start. The earlier you make extra payments, the more you save — because each extra dollar eliminates interest compounding over the remaining term.
What is an amortization schedule and how do I read it?
An amortization schedule lists every payment over a loan's life, showing how much goes to interest vs. principal each month. Early in a Washington mortgage, most of your payment covers interest. On $417,000 at 6.8% (30 yr), month 1: ~$2,363 interest / ~$356 principal. By month 300 (year 25), the split flips — most goes to principal. Use the "Monthly" tab in the calculator to see every row.
Is a 15-year or 30-year mortgage better in Washington?
On $417,000 at current rates (6.8% / 30yr, 6.1% / 15yr): 30-year pays $2,719/month, total interest $561,670. 15-year pays $3,702/month, total interest $249,296. The 15-year saves $312,374 but costs $983 more per month. Washington homeowners with strong cash flow often prefer the 15-year; those who want flexibility (or expect to invest the difference) choose the 30-year.
