Understanding Amortization Schedules
What Is an Amortization Schedule?
An amortization schedule is a complete table showing every mortgage payment over the life of your loan. Each row displays the payment number, opening balance, total payment amount, how much goes to principal, how much goes to interest, and the remaining balance. This helps you see exactly where your money goes each month.
Why Early Payments Are Mostly Interest
Mortgage interest is calculated on the remaining balance. At the start, you owe the full loan amount, so interest charges are highest. Your fixed monthly payment first covers interest, and whatever remains reduces principal. As principal decreases, so does interest, freeing up more of your payment to pay down the balance. This is why the shift happens gradually over decades.
How Extra Payments Affect Your Loan
Any payment above your required monthly amount goes directly to principal. This reduces future interest charges and shortens your loan term. Even an extra $100 per month on a 30-year mortgage can cut 7-9 years off the loan and save tens of thousands in interest. The earlier you make extra payments, the greater the impact.
Tips for Paying Off Your Mortgage Faster
Make biweekly payments
Pay half your monthly amount every two weeks. You will make 26 half-payments (13 full payments) per year instead of 12.
Round up your payment
Round $1,247 up to $1,300 or $1,500. The extra goes straight to principal and compounds over time.
Apply windfalls to principal
Use tax refunds, bonuses, or inheritance to make lump-sum principal payments. Even one extra payment per year helps.
Refinance to a shorter term
Switching from 30-year to 15-year mortgage increases monthly payment but dramatically reduces total interest paid.
