How it works

Total budget = 10 percent of income. Subtract insurance and fuel to get the loan payment, convert it to a loan amount at your rate and term, and divide by 0.8 to include the 20 percent down payment.

Worked example

On 6,000 a month, the budget is 600. After 350 for insurance and fuel, about 250 remains for the payment, which supports a car of roughly 13,000.
