Frequently Asked Questions
How is the affordable price worked out?
It reverses the loan formula: from your monthly payment, rate and term it finds the largest loan you can carry, adds your down payment, then removes sales tax to get the sticker price.
Should sales tax be included?
Yes. Tax is usually financed into the loan, so the tool separates the sticker price from the tax to keep the numbers realistic.
What monthly payment is sensible?
A common guideline is to keep your total car costs under about 15% to 20% of take-home pay, including insurance and fuel.
Does a longer term help?
A longer term lowers the monthly payment and lets you afford more, but you pay more interest overall and risk owing more than the car is worth.
What is not included?
Insurance, fuel, maintenance, registration and repairs. Budget for these on top of the loan payment.
Is my data private?
