Loan calculators

Instalment credit and revolving credit behave in ways that are not intuitive. These tools make both visible.

2 calculators

Auto Loan CalculatorCalculate the amount financed on a car including sales tax and trade-in credit, the monthly payment, total interest, and what stretching the term to 72 or 84 months really costs.Credit Card Payoff CalculatorSee how long a credit card balance takes to clear on minimum payments, what each extra dollar removes, and how paying a fixed 3% or 5% of the balance compares.

About this cluster

The benchmark rates in this cluster come from the Federal Reserve's G.19 Consumer Credit release, the monthly statistical release that reports commercial bank interest rates on new car loans and credit card plans. It excludes mortgage debt, which is why the mortgage cluster uses a different source.

How the figures are checked

Each calculator in this cluster states its formula, ships with worked examples that were checked against a known answer by an independent second implementation, and lists the primary source and retrieval date behind every external figure. The full method is described on the methodology page.
