Car Affordability Calculator — How Much Car Can You Afford?

Find out how much car you can truly afford based on your income, existing debts, and the full cost of ownership — payment, insurance, gas, and maintenance.

Quick answer: Car affordability should include loan payment, insurance, fuel, maintenance, registration, and depreciation. A lender approval can be higher than what fits safely in your monthly budget.

Frequently Asked Questions

Everything you need to know.

What percentage of income should go to a car payment?
Financial advisors recommend keeping all transportation costs — payment, insurance, fuel, maintenance — under 15–20% of take-home pay. On $5,000/month take-home, that's $750–$1,000/month total transportation. A payment alone should be no more than 10–15%.
Should I buy or lease a car?
Buy if: you drive over 15,000 miles/year, want to own long-term, or want to modify the vehicle. Lease if: you want a new car every 3 years, drive under 12,000 miles/year, and qualify for low money factor (equivalent of APR). Most financial experts prefer buying — leasing optimizes for low payment, not low total cost.

Yes. SwitchWize calculators are free, and you do not need an account to run scenarios or view the result.
