Writing a complex formula in excel to calculate overtime hours

Question

I want to write a formula in excel to obtain a certain output, but I couldn't.

The situation is that:

We have workers working in a site, performing 2 operations= A and B.

We want to pay the workers for overtime hours resulting for operation B only.

So, this overtime exists when one of two situations happen:

• Time for operation B exceeds 8 hours. or
• Total time for operation A and b exceeds 8 hours.

So, to check if there is an overtime, we should sum hours of operation A and B, (so they are linked).

But after that, we want to exclude the operation A hours, and pay for the amount for B only.

So, they are linked necessary, but we want to un-link them at second step.

How can we do this?

Answer 1

Assuming A1 is the value of operation A hours, A2 is the value of operation B hours, and B1 is the result (overtime hours). In B1 put :

 =if(OR(A2>8,(A1+A2)>8)),A2,"No overtime")

Hope that helps.
