Shopify Profit Calculator for Real Order Margins

Q: What is the difference between gross and net profit in Shopify?

Gross profit subtracts COGS only, while net profit subtracts all operating costs tied to the order - fees, shipping, ad spend, and refunds. For a typical DTC brand, the gap between gross and net margin is 18-25 percentage points.

Q: Should ad spend be allocated per order?

Yes. Channel-level ad spend should be allocated to attributed orders so margin comparisons are consistent across channels. Without per-order allocation, high-spend channels can appear profitable when individual orders are actually margin-negative.

Q: How often should I recalculate?

Daily for fast-moving paid channels where CPA shifts quickly, and weekly for full product and channel planning reviews. Brands running over $5K/month in ad spend typically benefit from daily margin checks.

Revenue alone hides margin risk. Use this calculator model to estimate true order profit after COGS, shipping, payment fees, ad spend, and refunds.

Calculator formula

Start with revenue excluding tax. Subtract COGS, payment processing fees, shipping costs, ad spend allocation, and refunds to reach net profit.

This structure prevents false positives where revenue grows but margin shrinks.

Net profit = Revenue ex tax - COGS - Fees - Shipping - Ad spend - Refunds
Net margin = Net profit / Revenue ex tax
Breakeven order value = Fixed + variable costs for the order

How to use this in weekly planning

Run a weekly sample on your top 20 SKUs and compare margin by channel. If a channel is high revenue but low margin, lower bids or adjust offer structure.

Keep one threshold for healthy margin and one for minimum acceptable margin so your team can triage quickly.

Where merchants usually miscalculate

Most stores ignore either refund impact or shipping leakage. Both distort margin and can make unprofitable campaigns look healthy.

Using average COGS instead of variant-level COGS
Ignoring payment gateway fixed per-order fees
Missing return shipping and restocking costs
