• UR is the unit rate ($/mile) • W is the weight factor • D is the distance (miles) To calculate the overflight fee, multiply the unit rate, by the weight factor, and distance. ## How to Calculate Overflight Fee? The following steps outline how to calculate the Overflight Fee. 1. First, determine the unit rate ($/mile).
2. Next, determine the weight factor.
3. Next, determine the distance (miles).
4. Next, gather the formula from above = OF = UR * W * D.
5. Finally, calculate the Overflight Fee.
6. 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.

unit rate (\$/mile) = 1.25

weight factor = 3.75

distance (miles) = 2,000

OF = UR * W * D =  ?
