Let's say a restaurant makes a $10 sale with an Interchange Plus pricing structure.
If the card used to pay for the meal has an Interchange rate of 1.80% + $0.20, the restaurant will pay (1.80% x $10) + ($0.20 + 1 transaction) = $0.38 in interchange fees
Let's say for network fees, there is a 0.20% rate charged (this rate is also set by the networks), 0.20% x $10 = $0.02 in Network Fees.
Now let's take a look at the Plus portion of this rate structure.
Using the same example, if the restaurant is paying Interchange (Cost) + 0.50% + $0.10, then the Plus (also known as the markup) would be 0.50% of their volume and the $0.10 per transaction.
On the same $10 sale, the markup will be: (0.50% x $10) + ($0.10 x 1 transaction) = $0.15 in "Plus" fees This gets paid to Toast.
The restaurant will pay $0.55 TOTAL for this $10 transaction
额外信息
Interchange and network fees are set by the card issuers (banks) and the networks (Visa/Mastercard/Discover). With Interchange Plus, these fees are passed onto the restaurant with a small fee applied on top of the "plus" fee.
Interchange and network fees are different for every card type, e.g. debit, credit, rewards, international, keyed, swiped, etc., and each has its own associated cost. This mix of card costs makes up the card mix.
