The mathematical gross-up is straightforward, but permission to surcharge is not. Laws, card-network rules, disclosure requirements, and caps vary by jurisdiction and card type; debit-card surcharges may be prohibited.

Stripe custom pricing, manually entered cards, alternative payment methods, disputes, tax products, and instant payouts are outside this estimate.
