My understanding of your request is to include a 2.5% extra bonus once the fifth deal is done, and apply it to all of the first five deals. If this is accurate, you can replace your fifth formula with the following:
You will need to change E21:E24 if the formulas are in a different place.
Then for your second request, my understanding is after the ninth deal, you want to add an additional 5% to each of deals 1-8, but not the ninth deal. If this is accurate, you can replace the ninth formula with the following:
Again, you will need to change the references to column E with the appropriate column if needed.
