How to get the percentage of the difference of 2 totals?

[anoble1]

I have a query that I am trying to get a field to calculate a percentage based off 2 totals.

Here is my current query field that I am editing.

BONUS: Sum(Nz([BD_PRC])-Nz([BD_NET]))

I wish I could take that what spits out and get 10% of that total. So, if I ran that query and that field gave 1527.2 I would like the formula to calculate 10% which would be 152.72 I have tried a few things, but didn't work. Ideas?

Divide it by 10

BONUS10Percent: Sum(Nz([BD_PRC])-Nz([BD_NET])) / 10
