# Qualification Ratio

## What it is:

A qualification ratio is actually two ratios that banks use to determine whether a borrower is eligible for a mortgage. The two ratios generally are:

Total Borrower Debt/Monthly Income

Borrower's Total Monthly Debt Payments/Monthly Income

## How it works (Example):

For example, let's assume that Borrower X has \$4,000 of monthly income and \$30,000 of student loans and credit card debt, on which he pays \$600. Borrower X wants an 8%, 30-year, \$250,000 mortgage. The monthly payment on that mortgage, including homeowners insurance and property taxes, works out to \$2,200.

Using this information and the formulas above, the bank can use qualification ratios as part of its determination of whether Borrower X is a good lending risk.

Total monthly borrower debt payments/monthly income = (\$600 + \$2,200)/\$4,000 = 0.70

Borrower's monthly housing expense/monthly income = \$2,200/\$4,000 = 0.55

## Why it Matters:

Qualification ratios are intended to reduce banks' risk of default. Each lender has its own standards, though a rule of thumb is that total debt payments to income should not exceed 0.36 and housing expenses to income should not exceed 0.28. (Borrower X in our example exceeds those thresholds and thus probably won't get the loan.) Borrowers that do not meet banks' minimum qualification-ratio thresholds usually either do not receive loans, must make larger down payments, or must pay higher interest rates.
