Why is so little of my early payment going to principal?

Interest is charged on your outstanding balance, which is largest at the start. So early payments cover a lot of interest and little principal. As the balance falls, the principal share of each payment grows.

How does a prepayment change my amortization schedule?

A lump-sum prepayment goes straight to principal, lowering the balance. That reduces future interest and shortens the schedule, so you reach a zero balance sooner and pay less interest overall.

Where can I get my amortization schedule?

Your lender can provide one, and many online mortgage calculators generate a full schedule from your loan amount, rate, payment frequency, and amortization period.

What is Amortization Schedule?

An amortization schedule is a table that breaks down each mortgage payment into its principal and interest portions over the full life of the loan. It shows how the balance declines payment by payment until it reaches zero. The schedule reveals that early payments are mostly interest, while later payments are mostly principal.

Key points

An amortization schedule shows each payment's split between principal and interest.
It tracks the declining balance from the first payment to zero.
Early payments are mostly interest; later payments are mostly principal.
It is built from the loan amount, rate, payment frequency, and amortization period.
It helps you see total interest paid and the impact of prepayments.

Amortization Schedule explained

An amortization schedule lays out every scheduled payment of your mortgage and shows, for each one, how much goes toward interest, how much reduces the principal, and what balance remains afterward. Because interest is charged on the outstanding balance, early payments carry a large interest share, and as the balance shrinks, more of each payment attacks the principal.

The schedule is generated from your loan amount, interest rate, payment frequency, and amortization period. It is a useful planning tool: by reading it, you can see exactly how much equity you build over time, how much total interest you will pay, and how an extra prepayment would accelerate your progress toward a zero balance.

What a Amortization Schedule is for

An amortization schedule exists to make the long-term mechanics of a mortgage visible. Rather than seeing only a monthly payment figure, you can trace how each dollar is applied, understand the true cost of borrowing, and project your balance at any point in the future.

How it can help you

Reading an amortization schedule helps Canadian borrowers see how slowly principal falls in the early years and how prepayments can speed things up. It turns an abstract mortgage into clear numbers.

When it comes up

An amortization schedule is handy when deciding whether to make a lump-sum prepayment or choose a shorter amortization. By comparing schedules, you can see exactly how much interest each choice saves and how much faster you reach a zero balance.

Example: reading the first and later payments

On a $400,000 mortgage at 5% over 25 years, your first monthly payment of about $2,330 might apply roughly $1,665 to interest and only $665 to principal.

Fifteen years later, with the balance much lower, that same $2,330 payment could apply about $1,000 to interest and $1,330 to principal. The amortization schedule shows this gradual shift line by line, making it clear how equity builds slowly at first and faster as the loan matures.
