Why Your Early Payments Are Mostly Interest
A mortgage amortization schedule shows exactly how each monthly payment is split between principal and interest over the life of the loan. In the early years, a much larger portion of your payment goes toward interest, since interest is calculated on your full remaining balance. As you pay down the balance over time, more of each payment shifts toward principal, which is why your equity builds slowly at first and then accelerates in later years.
This structure explains a few things that surprise a lot of new homeowners:
- Selling or refinancing in the first few years often means you’ve built less equity than expected
- Extra principal payments made early in the loan save far more interest than the same payment made later
- A 15-year loan builds equity much faster than a 30-year loan at the same rate
You can see your own full schedule using our home amortization calculator, and if you’re weighing whether extra payments make sense for your situation, our mortgage calculator lets you compare different payment scenarios side by side.
