E-commerce Profit Truth

Your margin is not what the platform tells you it is.

Shopify shows you sale price minus product cost and calls it margin. Reality includes apps, transaction fees, payment processing, returns, disputes, advertising, and the cross-currency hit on settlement. We rebuild margin from first principles.

Source standards for ecommerce calculations

Shopify plan, transaction, and payment assumptions are checked against public pricing pages, then separated from user-entered operating costs such as app spend, shipping, returns, product cost, duty, and ad spend. We do not estimate financing products, negotiated enterprise contracts, or tax obligations unless a calculator explicitly says so.

How to use this section

Work through the numbers in the order that prevents bad decisions.

  1. 01

    Start with contribution margin

    Revenue is not the operating metric. Begin with product cost, payment fees, shipping, returns, and ad spend so the calculator shows the order-level margin you can actually keep.

  2. 02

    Separate platform fees from growth costs

    Shopify plan cost is usually smaller than payment processing, apps, and paid acquisition. The true-cost pages keep those buckets separate so you do not upgrade a plan to solve a marketing or return-rate problem.

  3. 03

    Use landed cost before pricing a SKU

    A product that looks profitable at supplier quote can lose margin after freight, insurance, duty, broker fees, and currency spread. Landed cost should be checked before ROAS or discount strategy.

Long-form explainers that go deeper than the calculators — the hidden traps, the real math, and how operators actually cut the bill.

Why this category exists

  • Apps quietly eat margin

    Most stores carry 8–15 paid Shopify apps. At an average of $25/month each, that's $2,400+/year that doesn't show up in any product margin calculation.

  • Currency settlement spreads

    If you sell in USD but settle in NZD/AUD, your effective margin drops 2–4% via Shopify Payments' FX markup unless you use a multi-currency bank account.

  • Dispute reserves are real

    Card disputes carry $15+ fees plus chargeback amount. A 0.6% dispute rate erodes 1.5%+ off effective margin for a typical AOV.
