What Each Value Means

Monthly Gross Income ($/month): Your total earnings before taxes, health insurance, 401(k), or any other deductions are subtracted. GM Financial uses gross income — not net (take-home) pay — in all calculations.
PTI — Payment to Income Ratio (%): Your monthly car payment divided by your monthly gross income, expressed as a percentage. GM Financial uses PTI to assess whether the car payment is affordable relative to your income.
DTI — Debt to Income Ratio (%): All monthly debt payments (car, rent/mortgage, credit cards, student loans) divided by monthly gross income. GM Financial uses DTI to evaluate total financial burden. A DTI under 40–45% is generally preferred.
YTD — Year-to-Date ($): The cumulative gross income earned from January 1st through the date shown on your most recent pay stub. GM Financial uses YTD figures to calculate an annualized monthly income when year-round pay history is unavailable.

Frequently Asked Questions

What does the GM income calculator calculate?

It converts your pay — whether hourly, bi-weekly, salary, or YTD — into monthly gross income. GM Financial uses your monthly gross income (before taxes) to evaluate auto loan applications and calculate your payment-to-income (PTI) ratio.

How does GM Financial calculate income from a bi-weekly paycheck?

GM Financial multiplies your bi-weekly gross paycheck by 26 (the number of bi-weekly pay periods in a year), then divides by 12. For example, a $2,400 bi-weekly paycheck = ($2,400 × 26) ÷ 12 = $5,200/month. A common mistake is multiplying by 2 instead, which underestimates income by about 8.7%.

How do I calculate monthly income from YTD pay on my stub?

Divide your YTD gross income by the number of pay periods you've received, then multiply by your pay periods per year and divide by 12. Example: $14,500 YTD after 13 bi-weekly periods = ($14,500 ÷ 13) × (26 ÷ 12) = $2,500/month.

What is the minimum monthly income for GM Financial auto financing?

GM Financial typically requires a minimum monthly gross income of $1,500–$2,000. The exact minimum can vary by dealership, vehicle price, credit profile, and down payment amount.

What is the difference between GM Financial and AmeriCredit?

They are the same company. General Motors acquired AmeriCredit in October 2010 and renamed it GM Financial. There is no separate product — AmeriCredit simply became GM Financial's consumer auto finance division.

What payment-to-income ratio does GM Financial prefer?

GM Financial generally prefers a payment-to-income (PTI) ratio under 15–20%. This means your monthly car payment should be no more than 15–20% of your gross monthly income. A PTI under 10% is considered excellent.

Does GM Financial count overtime pay or bonus income?

GM Financial may count overtime and bonus income if it can be documented and demonstrated to be consistent. Usually this requires 2 years of W-2s or tax returns showing the additional income. Variable income is typically averaged over 24 months.
