What a Payment Fee Actually Includes

A payment fee is the cost of collecting an order through a payment provider, not the full cost of delivering it. Separate each documented component before measuring bedding margins: a percentage charge, a fixed fee per transaction, any currency-conversion cost, and other provider or gateway charges. Do not include shipping, sales tax collected from the customer, product cost, fulfilment or delivery expenses.

For an order, calculate the percentage charge from the transaction amount, then add the fixed charge. Record currency conversion separately when the payment and settlement currencies differ, since it can change the amount received without changing the displayed selling price. If a provider applies tax to its own fee, keep that line separate from customer sales tax. The profit margin calculator can help test the resulting fee against order economics.

Why Low-Value Orders Suffer Most

A fixed payment charge takes the same dollar amount from every order, so it consumes more margin on a low-value bedding purchase. A $0.30 fixed charge is 1% of a $30 order but only 0.2% of a $150 order. A percentage fee behaves differently: at 2.9%, it rises with the order value, keeping its share constant before any other adjustments.

The following illustrative schedule shows the contrast. It uses order values before tax and combines a $0.30 fixed charge with a 2.9% percentage charge. Treat the figures as a method for testing your own documented fee terms, not as a provider quote.

Worked example with sample numbers

This example is illustrative. It uses sample numbers for a bedding store selling in Canada. They are made up to show the method, they are not a benchmark, and your own figures will differ.

Formula: Payment fee = order value x percentage + fixed amount.

How to Read the Worked Example

Read the worked example from left to right. Begin with the customer’s charged order value, then identify which part is merchandise and which part is tax. Tax collected for remittance is not the store’s product revenue, so do not treat it as margin. For Canadian orders, select the applicable provincial GST/HST treatment; the Canada Revenue Agency lists the rates by province in its GST/HST rate guidance.

Next, follow the payment provider’s calculation basis exactly as shown. Check whether the percentage applies to the taxable charge, the full amount paid, or another documented base, then add the fixed component separately. That produces the payment cost for the order. The final step subtracts payment cost and the other costs included in the example from the relevant revenue base to produce contribution. Divide that contribution by the same revenue base to get the contribution margin percentage. The key is consistency: do not compare a fee calculated on the tax-inclusive charge with a margin calculated on product value alone. To test your own assumptions, enter the same revenue and cost definitions into ORVX’s profit margin calculator.

Refunds, Chargebacks and Currency Conversion

A returned bedding order has two separate effects: the order value is reversed, and the original payment fee may be treated differently by the provider. Some agreements return the percentage fee, some retain it, and some retain or add a separate refund charge. Do not assume that refunding the customer restores the full processing cost. Check the provider statement and record the fee treatment independently from the merchandise, shipping and tax reversal.

A chargeback is not simply a refund requested by the customer. The payment may be reversed while the provider also applies a dispute fee or deducts the disputed amount during the review. If the dispute is resolved in your favour, the principal or fee treatment may change according to the provider’s terms. Compare chargeback cost with refund cost using the same order value, then track dispute rate separately: it signals payment and fulfilment risk, while refund rate shows returned demand or product dissatisfaction.

Non-CAD orders can create a third difference. The customer’s charged currency, the provider’s conversion rate, any conversion fee or spread, and the currency in which funds settle can all affect the amount received. A refund may occur at a different exchange rate, so the returned amount and the original CAD-equivalent revenue may not match. ORVX keeps each merchant’s trading currency separate and never mixes currencies in one figure; it also reports refund value against revenue and realised revenue from delivered orders only.

How to Compare Payment Providers Fairly

Compare providers with one controlled scenario, not each provider’s preferred example. Use the same order values, product and tax treatment, payment methods, settlement currencies and transaction outcomes. For a Canadian bedding store, keep a domestic-currency order separate from a foreign-currency order, and document whether the fee is assessed on merchandise, tax, shipping or the full charged amount. Apply the same assumptions to every provider.

Use percentage cost to compare the rate applied to an order and to see how costs change as order value rises. Use fixed cost to test the effect of the per-transaction charge at each order value, especially where bedding accessories or smaller baskets are involved. Use total cost when deciding which fee structure fits your actual sales mix: add the percentage and fixed components for every tested order, then weight the results by the share of orders using each method and currency. A profit margin calculator can help check the resulting margin impact without changing the comparison assumptions.

Turning Fee Analysis Into Margin Decisions

Payment findings should change the question you ask, not dictate a single answer. If fees take a larger share of low-value orders, test a minimum order threshold, bundle, or shipping offer that raises basket value. Measure the effect on contribution, not just conversion rate. A promotion that adds $10 in sales but $8 in discount and payment cost may reduce profit.

Pricing decisions require the same discipline. A fee percentage can indicate whether a price point is exposed, while dollar cost shows the amount removed from each order. Review both alongside product margin: a high-margin sheet set may absorb a fee more easily than a low-margin mattress protector. The profit margin calculator can help model the arithmetic before changing a price.

Payment-method results also depend on order mix. Compare methods by realized contribution, approval and completion behaviour, refunds, and customer or product segments, not one headline rate. A method with a higher documented fee may still deserve testing if it is concentrated in larger or more profitable baskets; a cheaper method may not help if it changes who completes checkout. ORVX can show product, collection and customer profitability so those decisions use your store’s actual mix rather than an average order assumption.

Payment fees affect bedding margins through more than a headline rate. A fair assessment separates percentage and fixed charges, tests different order values, accounts for refunds and disputes, and keeps currency treatment consistent. That gives a Canadian bedding store a clearer basis for deciding which payment costs require action.
