Shopify Profit Guide

Quick answer

Shopify profit is what remains after all order and store costs are included. Product cost alone is not enough. Payment fees, shipping, packaging, apps, discounts, refunds, chargebacks, and advertising can turn a profitable-looking sale into a weak or losing order.

True Shopify profit formula

Profit = Revenue - product cost - payment fees - shipping - packaging - ads - refunds allowance - app/overhead allocation

The free shipping problem

Free shipping can improve conversion, but it is not free for the store. The cost must be built into product price or margin. If shipping is ignored, the profit calculation becomes unrealistic. Test both price and conversion assumptions before relying on free shipping.

Apps and fixed costs

Shopify apps can quietly reduce profit. A £20 app may be fine for a store with hundreds of monthly orders, but expensive for a store with only a few sales. Divide monthly app and software costs by order count to estimate overhead per order.

Advertising and break-even

If a product has £15 contribution profit before ads, the store cannot spend more than £15 to acquire the order without losing money before overhead. The safer target is below break-even so refunds, slow days, and testing costs do not wipe out profit.

Common mistakes

• Calculating profit before ad spend.
• Ignoring payment processing fees.
• Treating free shipping as no cost.
• Not accounting for refunds or chargebacks.
• Letting app subscriptions grow too early.
• Using revenue screenshots as proof of profit.
• Discounting without checking margin.

Practical store review

Calculate profit by product and by order source. Paid ads, organic traffic, email, and repeat customers can have very different economics. A store becomes stronger when it knows which products and traffic sources actually produce profit, not just sales.
