Use the output as a threshold, not a forecast.
Store dashboards report sales quickly, but the operating result requires a common view of product cost, payment fees, logistics, expected return loss, software and marketing. This calculator compresses those inputs into a simple monthly P&L.
Use net sales after discounts and refunds when possible. Then compare the modeled result with bookkeeping each month and replace estimates with actual percentages. The purpose is not to replace accounting; it is to expose which operating lever has the largest impact before the month closes.
Monthly Shopify operating profit
The model subtracts COGS, payment and optional transaction fees, order-level fulfillment and shipping, expected return loss, advertising, the Shopify plan, apps and other fixed costs from monthly net sales.
Maximum break-even ad spend is profit before advertising. It shows the entire amount theoretically available for media at zero operating profit, not a recommended budget. Average order value and blended ad cost per order are derived from sales, orders and ad spend.
At 25,000 in sales and 500 orders, every 1.00 change in per-order fulfillment moves monthly profit by 500. The same model makes return rate and payment-fixed fees visible at store scale.
What this calculation does—and does not include.

- Monthly net sales and order volume
- COGS, payment/transaction fees and fulfillment

- Operating profit, margin and break-even ad-spend ceiling

Editable model; official Shopify pricing used as context
Reviewed 2026-08-23. Review dates describe the live model, not a guarantee that a third-party fee has not changed since.
Limitations to keep visible
- Payroll, tax, financing costs, chargebacks and inventory write-downs are excluded unless entered in other fixed costs.
- Revenue divided by ad spend is a blended ratio, not a causal measurement of incremental advertising performance.
- Shopify plans, payment rates and third-party app pricing differ by market and contract; enter your actual rates.

Should revenue include tax?+
For management profitability, use net sales excluding pass-through tax where your accounting setup treats tax as a liability rather than revenue.
What does maximum break-even ad spend mean?+
It is the modeled profit before ads. Spending all of it would leave zero operating profit, so a real budget should be lower and should include an uncertainty buffer.
Can I use this for another ecommerce platform?+
Yes. Enter the platform's payment, transaction, software and fulfillment costs. The name is Shopify-focused because that is a common use case, but the monthly equation is platform-agnostic.
