Shopify Transaction Fee Calculator

Transaction fees look small per order but compound quickly at volume. This calculator totals the percentage-based card fee, the fixed per-order fee, and any third-party gateway surcharge so you can see your effective rate.

Inputs

Orders per month

Average order value

Card rate (plan)

Third-party gateway fee

Results

Total fees

$655.50

Percentage fees: $565.50
Fixed per-order fees: $90.00
Effective fee rate: 3.0%
Revenue after fees: $18,845

Effective rate = total fees ÷ revenue. It is always slightly above the card rate because of the $0.30 fixed fee — the effect is larger at low order values.

Formula

Fees = Revenue × Rate + Orders × $0.30 (+ Revenue × Gateway %)

FAQ

Why is my effective rate higher than my plan's card rate?

The fixed $0.30 per order adds a percentage that shrinks as order value grows. A $20 order pays 1.5% in fixed fees alone.

Do refunds reduce fees?

Card fees on refunded orders are generally not returned, which is worth tracking if your return rate is high.
