Frequently Asked Questions
How is the max car payment calculated?
We use the 15% rule: your maximum car payment should not exceed 15% of your monthly income minus existing monthly debt payments. This helps keep your budget sustainable.
Does this include taxes and fees?
No, the max car price is an estimate based on the loan amount you can finance. Taxes, registration, and dealer fees are additional and vary by location.
What if my debt payments are very high?
If your existing debt is high, your affordable car payment may be reduced or zero. Consider paying down debt before taking on a new auto loan.
