About this Shopify Profit Calculator
E-commerce profit depends on more than product cost. Payment fees, ad spend, shipping, apps, returns, and platform costs can turn a good-looking gross margin into a weak contribution margin.
Who this calculator is for
- Shopify merchants pricing products and bundles.
- E-commerce teams checking ad economics before scaling.
- Dropshippers and DTC brands estimating contribution profit per order.
When to use it
- Estimate profit per order before launching a product.
- Check whether ad spend leaves enough room for margin.
- Model payment fees and return allowance using your own assumptions.
How to use this calculator
- Enter selling price and direct product cost.
- Add shipping, ad cost, and platform or app cost per order.
- Enter payment fee assumptions and expected return allowance.
- Review profit per order, margin, fee, and total variable cost.
Key assumptions
- Enter your own payment pricing because processor and Shopify fee schedules can change.
- The model is per order and does not include taxes, refunds already processed, chargebacks, or fixed payroll.
- Calculations run locally and do not store store or product data.

How this calculator works
Payment fee = selling price x fee percent + fixed fee. Return allowance = selling price x return allowance percent. Profit per order = selling price - product cost - shipping - ad cost - platform cost - payment fee - return allowance.
Profit per order = selling price - product cost - shipping cost - ad cost - platform cost - payment fee - return allowance. Payment fee = selling price * payment fee percent / 100 + fixed fee.
Inputs explained
Ad cost per order
Average acquisition cost for one order, not total campaign spend.
Platform cost per order
Allocated cost for Shopify plan, apps, packaging, or other per-order overhead.
Return allowance
Expected revenue loss or support cost set aside for returns and replacements.
Understanding your results
Profit per order is a contribution estimate before taxes, payroll, fixed overhead, and financing. A low margin means the product may be sensitive to ad cost or return rate changes.
Example scenarios
DTC product
$49 price, $18 product cost, $6 shipping, $8 ads, $1 platform cost, 2.9% + $0.30 payment fee, and 3% returns yields about $14 profit per order.

Tips & Best Practices
- Use conservative return and ad-cost assumptions when testing new products.
- Compare profit per order against your break-even and cash-flow needs.
- Model bundles separately because shipping and ad costs may not scale linearly.
