This is arithmetic on the numbers you enter. It does not say what percentage or flat fee is normal, and it assumes the hours stay the same as spend changes, which they may not. Ad platforms and clients have their own rules on how fees and spend are handled: check your agreement.

Percentage or flat fee

A percentage of spend rises when the client spends more, whether or not your work rises with it. A flat fee stays the same when spend changes, so your hourly rate falls if the work grows. Comparing the two at the client's real spend, and at higher and lower spends, shows where each one stops paying you fairly.
