WooCommerce Profit Estimator

The WooCommerce Profit Estimator calculates order-level profit for a store using WooCommerce, including product cost, payment processing, shipping, packaging, discounts, and other variable expenses. WooCommerce core does not impose one universal transaction fee, so the calculator leaves payment and marketplace-related rates adjustable.

Store owners can use the result to review product pricing, shipping policies, coupon economics, and channel profitability. The output focuses on contribution profit for one representative order; fixed overhead such as salaries, hosting, software subscriptions, and rent can be added as an allocated per-order cost when needed.

1. Enter the order subtotal
Use merchandise value before coupons or manual discounts.

2. Record discount and shipping revenue
The customer payment equals discounted merchandise plus shipping charged.

3. Add cost of goods
Use the landed product cost for the items in the order.

4. Enter payment and fulfillment costs
Use the actual gateway rate, fixed fee, postage, packaging, and other order-level expenses.

5. Review contribution profit
Compare the profit and margin with fixed overhead requirements and customer acquisition cost.

Customer payment = Merchandise subtotal − Discount + Shipping charged
Processing fees = Customer payment × Processing rate + Fixed fee
Order profit = Customer payment − Cost of goods − Processing fees − Shipping and packaging − Other variable cost

Where:

  • Customer payment: amount collected before taxes under this model
  • Order profit: contribution remaining before fixed overhead
  • Break-even payment: payment needed to cover entered variable costs

Assumptions: Taxes, refunds, chargebacks, and fixed overhead are excluded unless represented in other variable cost.

What the result means

Estimated order profit is contribution after entered variable costs and before unallocated overhead.

Use store reports and gateway statements to replace the default assumptions with actual figures.

Given:

  • Merchandise subtotal: $120
  • Discount: $10
  • Shipping charged: $8
  • Cost of goods: $48
  • Processing: 2.9% + $0.30
  • Shipping and packaging: $11
  • Other variable cost: $3

Calculation:
Customer payment = 120 − 10 + 8 = $118.00. Processing fees = 118 × 2.9% + 0.30 = $3.72. Profit = 118 − 48 − 3.72 − 11 − 3 = $52.28. Margin = 52.28 ÷ 118 × 100 = 44.31%.

Result:
$52.28 contribution profit on the representative order.

Interpretation:
This amount is available to cover customer acquisition and fixed operating expenses before net profit.

Does WooCommerce charge the processing rate entered here?

The rate should come from your payment gateway or other service, not from a universal WooCommerce core fee. Enter the rate shown in your provider agreement.

Should tax be counted as revenue?

Usually pass-through sales tax is excluded from operating revenue and profit, but fee bases vary. Keep the revenue and processing-fee assumptions consistent with your reports.

How can I include hosting and plugins?

Allocate monthly fixed costs across expected orders and enter the per-order amount under other variable cost, while recognizing that this is an allocation rather than a true variable cost.

What if an order contains several products?

Enter the combined merchandise subtotal and total cost of goods for all items in the order.

How is contribution margin different from net margin?

Contribution margin subtracts modeled variable order costs. Net margin also reflects fixed overhead, payroll, depreciation, taxes, and other business-level expenses.
