How much is the Stripe fee for $100?
At Stripe's standard US rate of 2.9% + 30¢, a $100 domestic card payment costs $3.20 in fees. If the card was issued outside the US, the extra 1.5% adds $1.50, for $4.70 in total. Using Stripe Billing on the pay-as-you-go plan adds 0.7% of billing volume, or another 70¢. These figures follow Stripe's published US pricing.
