How to Calculate Default Rate

How to Calculate Default Rate
Default rates show the efficiency of loan collections.

Step 1

Determine the total number of defaults on loans a company has over the course of a year. For example, a small lender had three people default on personal loans this year. Alternatively, a small company defaulted on one loan during the year.

Step 2

Determine the number of loans outstanding during the year for the lender. In our example, the small lender had 100 loans outstanding during the year. In the alternate; the small company had 5 loans during the year.

Step 3

Divide the number of defaults by the number of loans outstanding during the year. In our example, 3 divided by 100 equals a 3 percent default rate. In the alternative, 1 divided by 5 equals a default rate of 20 percent for the year for the small company.
