The ratio defined as monthly housing expenses divided by monthly income is known as what?

• A. the housing expense ratio
• B. the front-end ratio
• C. the back-end ratio
• D. the debt-to-income ratio

Answer: (A)

The key idea is measuring affordability by looking at housing costs in relation to income. The ratio of monthly housing expenses to gross monthly income is called the housing expense ratio, also known as the front-end ratio. This focuses only on housing-related payments like principal, interest, taxes, and insurance (PITI), and shows what portion of income goes to housing.

In contrast, the back-end ratio uses all monthly debt payments—housing plus credit cards, car loans, student loans, etc.—divided by income. The debt-to-income ratio is a broader term that often refers to that overall debt load. So the described measure—housing costs divided by income—is the housing expense ratio, or front-end ratio. For example, if housing costs are $1,000 and gross monthly income is $4,000, the housing expense ratio is 25%.
