To pass the ticket fees on to the ticket buyer we first increase the final payment amount you charge the customer to account for the fees you’re paying Accelevents and Stripe. However, as you increase the total amount you ask Stripe to charge, you’re also increasing the Stripe fee, because Stripe’s pricing is a flat fee plus a percentage of the total charge amount. You’ll need to figure out what gross amount you need to charge such that, after Stripe deducts its fee, you receive some predictable net amount.
To save you some time, the calculation to determine that amount looks like this:
Total charge is how much you will have to charge in total
In the US (assuming standard US pricing of 2.9% + 30¢ per successful charge):
AE Fixed = $1
AE % = 1%
Stripe Fixed = 30c = 0.30
Stripe % = 2.9% = 0.029
