What’s driving this

Extra payments go straight to principal, reducing the amount you owe. That lowers the interest charged on future payments—interest compounds monthly on your remaining balance. Early extra payments matter more because they cut the balance before decades of compounding. With your current extra payments, you'll save $108,097 in interest and pay off 6 years early.
