Finance calculator
Editor
Set the loan details, optional extra payments, and timeline in one place. The payment estimate, payoff timing, chart, and amortization schedule all update instantly.
Start with the core loan details, then add extra payment assumptions if you want to compare a faster payoff path.
Loan details
These are the core assumptions that determine the base payment and repayment schedule.
Extra payments
Optional extra payments help you compare the standard loan path with a faster payoff strategy.
Timeline
Add a start date if you want the schedule and payoff card to show calendar dates.
The calculator assumes a fixed rate and evenly scheduled payments. Extra recurring payments are added to each payment, yearly extras land once each year, and a one-time extra payment is applied on the payment number you choose.

How it works
A loan payment calculator estimates the payment required to repay a fixed-rate loan over a set term. It combines the loan amount, interest rate, term length, and payment frequency to show the expected payment and full repayment cost.
Larger loan amounts usually increase the payment. Higher interest rates raise the borrowing cost and push more of each early payment toward interest. Longer terms can reduce the required payment amount, but they often increase total interest paid.
Extra payments reduce principal faster, which means less interest accrues on future payments. Even modest recurring or yearly extras can shorten the payoff timeline and lower the total interest cost by a meaningful amount.
The amortization schedule breaks the loan into individual payments, showing the payment date, total payment, principal, interest, any extra payment, and the remaining balance after each step. That makes it easier to see how the debt changes over time.
