01 · Check the terms
Use the fee schedule for the sale you make
Before changing a menu or product price, check your payment provider’s current fee terms for the way you take that payment. Record the percentage rate, any fixed charge per transaction, and the amount on which each fee is calculated. Terms can vary by provider and transaction type; do not treat a sample rate as a standard rate.
Confirm whether the percentage applies to the full amount charged or to another amount specified in your terms. If discounts, delivery, tax or other line items are part of the order, use the provider’s stated fee base rather than assuming which amounts are included. Recheck the terms when you change sales channels or the provider changes its schedule.
Then gather the other costs that belong to the sale: ingredients or materials, packaging, labor, a reasonable share of overhead, and order-specific costs. Keep the fee assumptions visible beside those costs so that candidate prices use the same basis.
02 · Identify each fee
A percentage fee and a fixed fee behave differently
- Percentage-based transaction fee
- Fee = the amount the provider charges against × the provider’s percentage rate.
- Fixed transaction fee
- A set charge for each transaction, such as a stated dollar amount per order.
The fee scales with the charged amount. For example, 3% of a larger eligible amount is more dollars than 3% of a smaller one. Verify the eligible amount in your provider terms.
It takes the same dollars from a small transaction as from a large transaction, so it is a larger per-unit burden on a small order. For an order with several items, allocate the transaction fee across the items before comparing per-item profit. Divide evenly when the items are alike; use a consistent, reasonable allocation for mixed orders.
Add the applicable percentage fee and allocated fixed fee to the product costs for the sale. A transaction fee that is omitted from the comparison reduces contribution by that amount. When you set a target margin, the price may need to rise to leave room for the fees as well as the other costs.
03 · Illustrative example
Vanilla cake boxes: add fees to the existing sample
All figures in this worked example are illustrative; the fee terms are hypothetical assumptions, not a provider quote or universal pricing.
The sample batch makes 8 boxes: $18.40 ingredients + $12.00 labor + $3.60 packaging + $4.00 overhead = $38.00 total batch cost. Divide $38.00 by 8 to get an illustrative cost of $4.75 per box before payment fees.
At the illustrative comparison price of $8.50 with no payment fee, contribution is $8.50 − $4.75 = $3.75 per box. Margin is $3.75 ÷ $8.50 = 44.1%. With no payment fee, the illustrative price for a 40% target margin is $4.75 ÷ (1 − 0.40) = $7.92.
Now assume, only for this example, a hypothetical 3% fee on the full $8.50 charged for one box plus a hypothetical $0.30 fixed fee for that single-box transaction. The percentage part is $8.50 × 3% = $0.255, which rounds to $0.26; add $0.30 to get $0.56 in fees. Contribution becomes $8.50 − $4.75 − $0.56 = $3.19, and margin is $3.19 ÷ $8.50 = 37.5%.
To solve for a 40% target margin under those same hypothetical terms, use (unit cost + fixed fee per item) ÷ (1 − fee rate − target margin): ($4.75 + $0.30) ÷ (1 − 0.03 − 0.40) = $8.8596, or about $8.86 before cent-rounding effects.
Cent rounding matters at the final price. At $8.86, the 3% fee rounds to $0.27; with the $0.30 fixed fee, total fees are $0.57. Contribution is $3.54 and margin is 39.95% (40.0% when shown to one decimal). If you need to meet or exceed 40% after rounding the transaction fees to cents, $8.87 gives $3.55 contribution and a 40.02% margin with the same $0.57 total fee.
The $3.75 and 44.1% figures preserve the sample’s zero-fee reference at $8.50. The hypothetical fee assumption lowers contribution at that price to $3.19 and margin to 37.5%; it is not a statement about what any provider charges.
04 · Compare the result
Compare contribution, then keep margin and markup distinct
Contribution per item is the selling price minus the product’s per-item costs and allocated payment fees. Compare candidate prices with the same recipe cost, fee terms, fee base and allocation method. In the illustrative example, $8.50 leaves $3.19 contribution with the hypothetical fees; $8.87 leaves $3.55 after cent-rounded fees and meets the 40% target to the shown precision.
Margin and markup are different ratios. Margin is contribution ÷ selling price. Markup is contribution ÷ unit cost, before payment fees. For the illustrative $8.50 fee scenario, unit cost is $4.75 and estimated fees are $0.56: $3.19 ÷ $8.50 is a 37.5% margin, while $3.19 ÷ $4.75 is a 67.2% markup. Their denominators differ, so do not use the terms interchangeably.
A higher price can improve contribution and may restore a target margin, but the estimate is only as useful as its inputs. Review the result alongside your actual provider terms, other costs, portions or order quantities, and the prices your customers will see.

Use the public one-product estimator
The estimator is a planning aid for comparing a product’s costs, payment-fee rate, target margin and candidate selling prices. Enter your percentage rate in Payment-fee rate (%). Include the fixed transaction fee allocated per item, along with packaging, labor, overhead or other per-item costs, in Other per-item costs (USD). Keep ingredient cost in its separate ingredient field. The estimator does not have a separate fixed-fee field, so calculate that per-item allocation from your order and provider terms first.
Open the public one-product estimator to enter your assumptions and compare selling prices. For the workbook’s $49 USD one-time price, availability and format status, see the calculator details on /pricing.
Review the cost basis alongside this fee: see the food cost per serving guide, labor cost per product guide, and overhead allocation guide. If your fee terms change, revisit the price with the food-business repricing guide.
