Get transaction fee for charge result object (braintree credit card processing)

Question

I would like to get the fee amount for a credit card transaction for braintree. Is there a way to get this?

$fee = $charge->transaction->serviceFeeAmount;

I was looking at:

https://developers.braintreepayments.com/reference/response/transaction/php#service_fee_amount

But this doesn't appear to be the fee I am looking for.

I am looking for the 2.9% + .30 fee. I know I can calculate it based on amount; but my first 50k is free and I don't want to change code when this switch happens.

That fee is not part of the braintree api. The reports would have that kind of information and I would contact support with any report related questions.
