How Loan Amortization Works
Loan amortization is the process of paying off a debt through regularly scheduled payments. Each payment is divided into two parts: interest (calculated on the current balance) and principal (which reduces your balance). The total payment amount stays constant throughout the loan term, but the split between interest and principal shifts every month.
The formula that determines your monthly payment — P × [r(1+r)^n] / [(1+r)^n − 1] — is designed so that your balance reaches exactly zero after the final payment. Your lender calculates this once at origination, and that amount becomes your fixed monthly obligation.
The line chart above shows how your remaining balance decreases over the loan term. Notice the curve is not linear — the balance drops slowly at first and then accelerates toward zero. This is because early payments are mostly interest, while later payments are mostly principal. For a 30-year mortgage, your balance is still about 85% of the original amount after 5 years of payments.
One powerful use of the amortization schedule is identifying the break-even point for refinancing. If you're considering a refinance, subtract your current balance (visible in the schedule for your current payment number) from your new loan amount to understand the true cost of refinancing.
