How to read the schedule
Each row is one monthly payment. Early in your loan, most of your payment goes to interest. Over time the split shifts — more goes to principal and less to interest. This is why making extra early payments saves so much money.
Why does so much go to interest at the start?
Your interest is calculated as a percentage of your remaining balance. At the start, the balance is highest, so interest is highest too. As you pay down principal, interest charges shrink — but the fixed payment stays the same, meaning more of it goes to principal each month.
What is the amortization crossover point?
The crossover point is the month when your principal payment finally exceeds your interest payment. On a 30-year loan at 7%, this typically happens around month 217 (year 18). Before that, interest dominates each payment.
How does refinancing affect my amortization?
Refinancing resets the clock. If you're 10 years into a 30-year loan and refinance to a new 30-year loan, you start over with a mostly-interest payment schedule. That's why it's worth using our Refinance Break-Even Calculator before refinancing.
Can I use this for a 15-year mortgage?
Yes — just enter 15 in the loan term field. A 15-year mortgage has a higher payment but dramatically less total interest. The schedule shows exactly how quickly you build equity compared to a 30-year loan.
