Separate default likelihood from loss size
A simple expected credit loss calculation combines the probability of default, the share lost if default occurs, and the exposure at default. Keep the probability and loss percentage in decimal form.
Expected loss = PD × LGD × EAD
For example, a 2% probability of default, 40% loss given default, and $100,000 exposure produce an expected loss of $800 over the period.
