The formula to calculate the cost of recruitment (COR) is:
\[ COR = \left( \frac{RR}{100} \right) \times S \]
Where:
Let's say the recruitment rate is 5% and the total salary is $100,000. Using the formula:
\[ COR = \left( \frac{5}{100} \right) \times 100000 \]
We get:
\[ COR = 5000 \]
So, the cost of recruitment (\( COR \)) is $5,000.
