The back-end ratio, also known as the debt-to-income ratio (DTI), calculates the percentage of your gross income required to cover your debts. Debts include your mortgage, credit card payments, child support and other loan payments. Most lenders recommend that your DTI does not exceed 36% of your gross income. To calculate your maximum monthly debt based on this ratio, multiply your gross income by 0.36 and divide by 12. For example, if you earn $100,000 per year, your maximum monthly debt expenses should not exceed $3,000.
