How Mortgage Payments Work

Most home loans use fixed monthly payments.

Each payment consists of:

• Principal (reduces your loan balance)
• Interest (paid to the lender)

During the early years of the loan, a larger portion of each payment goes toward interest.

As the balance decreases, more of each payment is applied to the principal.

Mortgage Formula

The calculator uses the standard mortgage payment formula:

M = P × r × (1+r)^n
    -----------------
    (1+r)^n − 1

Where:

• M = Monthly payment
• P = Loan amount
• r = Monthly interest rate
• n = Total number of monthly payments

This formula is used by banks and mortgage lenders around the world.

What Is an Amortization Schedule?

An amortization schedule shows how every payment affects your mortgage.

For each payment it displays:

• Payment number
• Monthly payment
• Principal paid
• Interest paid
• Remaining balance

This helps borrowers understand how their loan is repaid over time.

Tips for Reducing Mortgage Costs

• Make a larger down payment.
• Choose a shorter loan term if affordable.
• Compare interest rates from different lenders.
• Make extra principal payments whenever possible.

Even small additional payments can significantly reduce total interest over the life of the loan.
