Auto Affordability Calculator
Updated
We estimate conservative, moderate, and stretch vehicle prices based on a percentage of your gross monthly income.
A common rule is to keep your auto payment at or below 10–15% of your gross monthly income; 20% is a stretch. The right number for you also depends on other debts, savings goals, insurance, fuel, and maintenance costs.

What another $50/month buys
$2,411
more vehicle for every extra $50 of monthly budget, at your rate and term.
That is $2,555 of extra financing; the gap is the sales tax the pricier car adds, which gets financed too.

How this is calculated
We compute your maximum monthly payment as a percent of gross monthly income (10% conservative, 15% moderate, 20% stretched). We then binary-search the highest vehicle price that fits your budget given APR, term, taxes, and fees.
“What another $50/month buys” inverts the payment formula: it solves for the principal a $50 payment supports at your rate and term, then removes the sales tax that rides on the higher price, since that tax is financed too. It is the same math the tiers use, expressed per slice of budget rather than per tier.
