What is Payment-to-Income (PTI) Ratio?

Payment-to-Income (PTI) ratio is an important indicator used by lenders to assess the financial health of a consumer before granting them a loan. It is calculated by dividing your monthly car loan payment by your monthly income.

A higher PTI ratio indicates that the consumer has less money left over after making payments, while a lower PTI ratio indicates that the consumer has some reserves in their budget and denotes responsible borrowing behavior, which can help increase the chances of getting approved for loans in the future.

Payment-to-Income (PTI) Ratio Formula

PTI is calculated by dividing an individual's total recurring payments, such as car loan payments, by their total monthly income.

Monthly Auto Loan Payment ÷ Gross Monthly Income = PTI

What is a Good Payment-to-Income Ratio for a Car Loan?

Although lenders typically set their own thresholds regarding acceptable levels of payment-to-income ratios, it is generally advisable from a financial standpoint to shoot for no more than 10-15% of your income to go towards a car loan.

Making sure that you spend within your budget is the best way to maintain a good PTI ratio. Even if you can't get your dream car now, you may be able to finance something more affordable while you build up your income and credit to better position you for that dream car purchase down the road.

Lenders may also choose to look more broadly at your overall debt-to-income (DTI) ratio, to consider more debts than simply the car loan.
