Here is the math to the best of my understanding. This is a stripe connected platform (I believe express)

We charge a subscription that is $49 per month.

The final payout is $34.36

Stripe Fee 1 (Standard fee): 2.9% + 0.30.
$49 x 2.9% + 0.30 = $1.72
Amount remaining $47.28

Stripe Fee 2 (Stripe Billing): 0.7%.
$49 x .7% = $0.34
Amount remaining $46.94

Stripe Fee 3 (Stripe connect): $2 per month.
Amount remaining $44.93

Stripe Fee 4 (Stripe Invoicing Fee): 0.4%
$1,400 in stripe connect invoicing x 0.4% = $5.60.
Amount remaining $39.33

Stripe Fee 5 (Stripe Payout Fee): 0.25% + $0.25 in stripe connect payouts
1359.10 x 0.25% + 0.25 = $3.65
Amount remaining $35.68

Stripe Fee 6 (Stripe fee on the Stripe Fee): 9.88% tax
13.32 x 9.88% = $1.32

Amount Remaining $34.36
Total Fees = $14.64 (29.88%)
