How Square fees actually work
Square uses different rates depending on how the card was entered. Physically presenting the card to a Reader or Register is the cheapest; typing it in manually costs the most. The formula is always:
fee = (amount × rate%) + fixed
A $100 in-person sale at 2.6% + $0.10 costs $100 × 0.026 + $0.10 = $2.70 in fees, leaving $97.30. The same sale taken online at 2.9% + $0.30 would cost $3.20.
