Calculation: Base Fee + (Base Fee x Increase By Percentage)= Fee
Example 1
Increase the Base Fee by a Percentage: Increase the Base Fee of $200 by 150% with the end result being $500. In effect, you are adding to the Base Fee the Percentage of the Base Fee.
If you want the end result to be a percentage of the Base Fee (not increased by)
Example 2:
Increase the Base Fee of $228 by 20%
$228 + ($228 x .20)
$228 + 45.60
$273.60
Decrease the Base Fee to equal 20% of $228 for your self-pay fee schedule with the end result being $45.60.
$228 + ($228 x (0.20 - 1.00))
$228 + ($228 x (-.80)
$228 - $182.40
$45.60
