Enter the total number of defaults and the number of non-defaults into the Calculator. The calculator will evaluate the Default Rate. 

Default Rate Formula

DFR = DF / NDF * 100


  • DFR is the Default Rate (%)
  • DF is the total number of defaults
  • NDF is the number of non-defaults

To calculate the Default Rate, divide the number of defaults by the number of non-defaults, then multiply by 100.

How to Calculate Default Rate?

The following steps outline how to calculate the Default Rate.

  1. First, determine the total number of defaults. 
  2. Next, determine the number of non-defaults. 
  3. Next, gather the formula from above = DFR = DF / NDF * 100.
  4. Finally, calculate the Default Rate.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total number of defaults = 94

number of non-defaults = 500
