Getting a financial % off Revenue within selection

[Hope_AA]

I have a financial table with net total by Account Level and Year/Month. I want to be able to get the % of each Account Level from the 00_Revenue Level. so it would look like this : (i.e. for 2019-Jan, employee Costs would be -33,320,582/60,385,089 = -55.2%
