A loan amortization schedule shows every payment on your loan, how much goes to principal versus interest, and when the balance reaches zero. It is essential for understanding mortgages, auto loans, personal loans, and business financing.
By entering your loan amount, interest rate, term, and payment frequency, you get a full payoff plan with totals for interest and overall cost. Use it to budget, compare offers, and spot savings from refinancing or extra payments.
This calculator gives you a ready-to-export schedule so you can track payments, plan prepayments, and stay on top of your payoff timeline.
The calculator uses the standard amortization formula: Payment = P × r × (1 + r)^n / ((1 + r)^n - 1), where P is principal, r is periodic interest (annual rate ÷ payments per year), and n is total payments.
Each payment is split into interest (on the remaining balance) and principal (reducing the balance). As the balance declines, interest shrinks and the principal portion grows. The schedule runs until the balance reaches zero on the payoff date.
See monthly (or weekly) payments, total interest, and total amount paid across the loan.
Predictable payments make it easier to align debt payoff with cash flow.
Compare scenarios to see how lower rates or shorter terms change total interest.
Understand how extra principal payments can shorten the loan and cut interest.
Forecast monthly payments and equity build for home loans.
See payment breakdowns for cars, personal credit, or consolidation loans.
Model new rates or terms to understand savings before refinancing.
Track amortization for rentals and evaluate long-term cash flow
Assess how additional principal payments reduce total interest.
It is a table showing each payment's split between principal and interest, along with remaining balance until payoff.
We use the standard amortization formula: Payment = P × r × (1 + r)^n / ((1 + r)^n - 1), where P is principal, r is periodic rate (annual rate ÷ payments per year), and n is total payments.
Yes, you can switch between monthly, bi-weekly, and weekly frequencies to see how payments change.

Yes. If the rate is 0%, payments are simply principal divided by the number of periods.
