Shopify Profit Margin Calculator
Your Shopify margin isn't just sale price minus product cost - plan fees, payment processing, and apps all take a bite before you see the number. This calculator adds all three in.

- How this is calculated
Example: a small Shopify store
A $35 product costing $11 to make, with $4 of absorbed shipping and Shopify Payments' standard 2.9% + flat fee, comes out to a $19 per-unit margin (53%). Add a $39/mo Basic plan and $58/mo in apps, spread across 150 units sold a month, and the true margin drops to $18 (52%) once fixed costs are amortized per unit. Enter your own numbers above to see your real margin.
Methodology
Per-unit margin is sale price minus cost of goods, minus the payment processing fee (sale price × processing rate, plus a flat per-transaction fee), minus any absorbed shipping cost. Fixed costs - your Shopify plan and app subscriptions - are amortized per unit by dividing their monthly total by your estimated monthly units sold, then subtracted from per-unit margin to get the true margin after fixed costs.
Processing rates and plan prices are editable defaults, not guarantees - Shopify's own rates vary by plan, country, and whether Shopify Payments or a third-party gateway is used. Data source: Shopify's published pricing and Shopify Payments rate pages. Last reviewed: September 2026.

Frequently asked questions
- Does this include Shopify's transaction fees for third-party payment gateways?
- Not directly. This calculator models Shopify Payments' standard rate (a percentage plus a small flat fee per transaction). If you use a third-party gateway instead, Shopify charges an additional transaction fee on top of that gateway's own processing fee - enter your effective combined rate in the processing fee field to approximate it.
- How do I find my actual Shopify Payments rate?
- Your exact rate depends on your plan, your country, and whether the card is domestic or international. Check Settings > Payments in your Shopify admin, or Shopify's published pricing page, for the rate that applies to your store - then enter it here instead of the default.
- Should shipping be included if I charge the customer for it separately?
- No - leave the shipping field at $0 if the customer pays for shipping as a separate line item at checkout, since that cost is already covered by what they pay. Only enter a per-unit shipping cost here if you absorb it yourself (e.g. "free shipping" you're funding out of the sale price).
- How many apps is "too many" before they eat my margin?
- There's no fixed number - it depends entirely on your sales volume. A $100/mo app stack is negligible at 1,000 units a month but can quietly erase your entire margin at 20 units a month. Watch the "fixed cost per unit" figure above: if it's climbing toward your per-unit margin, it's time to audit which apps you actually use.
- How is this different from the general Profit Margin Calculator?
- This version bakes in Shopify-specific costs - plan tier, payment processing, and app subscriptions - so you don't have to calculate them by hand. For a non-Shopify business, use the Profit Margin Calculator instead.
