How it works

Questions and answers
Should I enter the sticker price?
Use the amount you actually plan to borrow. A sticker price can exclude sales tax, title fees and add-ons, while a down payment or trade-in can lower the principal.
Why are some results rounded?
Results display up to 8 decimal places. Calculations use the unrounded values; very small values use scientific notation. JavaScript floating-point arithmetic can introduce tiny rounding differences.
Are my inputs sent to a server?
The calculator processes inputs in your browser. Its code does not send your values to a server.
