Does this include tax and fees?

No — enter the drive-away price you want to finance. If you're rolling tax or fees into the loan, add them to the vehicle price.

What about a balloon payment?

This calculator uses a fully amortising loan. For PCP-style deals with a balloon, subtract the balloon from the loan amount, treat the balloon as a lump sum owed at term end, and use the mortgage calculator's interest-only mode for a closer estimate.

Should I put more down?

A bigger down payment reduces both monthly cost and total interest. As a rule of thumb, put down enough to avoid negative equity in the first year.

How this is calculated

The loan amount is the vehicle price minus your down payment and any trade-in value. The monthly payment is calculated using the standard amortising loan formula.

Longer terms lower the monthly hit but sharply increase total interest — and can leave you owing more than the car is worth for the first few years.
