Inputs

Input mode

Formula transparency

Source: default
Loan = Price − Down · PMT = P · r · (1+r)^n / ((1+r)^n − 1)

How to use it

  1. Enter the car price and your down payment.
  2. Add the rate and term.
  3. Add fees, insurance, and registration in advanced mode for the upfront cash.

Example

  • 18,000 car, 3,000 down, 6% over 5 years ≈ a ~290/month installment on a 15,000 loan.

What the result means

The financed amount is the price minus your down payment; upfront cash is everything you pay on day one.

Common mistakes

  • Ignoring fuel, maintenance, and insurance.
  • Choosing a long term just to lower the payment.
  • Forgetting registration and one-time costs.

Limitations

  • Doesn't include running costs — use the car ownership calculator for those.
  • Estimate only.

Frequently asked

How is the financed amount derived?
Financed amount = car price − down payment.
What is the upfront cash?
Down payment + fees + registration + one-time insurance.
How big should the down payment be?
Bigger lowers interest; 20%+ is a common rule of thumb.
Does it include running costs?
No — use the car ownership cost calculator for fuel and maintenance.
Is the result official?
No — it's an estimate. Rely on the financier's official offer.
