The formula to calculate the Amounts Generally Billed (AGB) is:
\[ AGB = \left( \frac{SCA}{SGC} \right) \times 100 \]
Where:
Let's say the sum of claims allowed (SCA) is $500,000, and the sum of gross charges (SGC) is $1,000,000. Using the formula:
\[ AGB = \left( \frac{500,000}{1,000,000} \right) \times 100 = 50 \% \]
So, the amounts generally billed is 50%.
