WooCommerce Profit Calculator
WooCommerce store profit.
Calculate WooCommerce store profit by entering revenue, product costs, hosting, plugins, payment fees, and marketing spend to see net margin.
What this tool does
This calculator models your WooCommerce store's monthly profitability by subtracting all operating costs from revenue. It accounts for product costs (calculated as a percentage of revenue), hosting fees, plugin subscriptions, payment processing charges, and marketing spend. The result shows your net profit in local terms and the corresponding profit margin as a percentage of revenue. Revenue and payment processing fees are the inputs that typically have the largest impact on the final figure. For example, a store with high product costs relative to revenue will see lower margins even with strong sales. The calculator assumes these costs remain constant month to month and does not account for taxes, shipping costs, refunds, inventory holding, or seasonal variation. Use this as an illustration of how different cost structures affect store profitability.

WooCommerce itself is free but total platform cost includes hosting (30-300/month), premium plugins (50-200/month for essentials), payment processing (2.9% + 30p typical), and theme/maintenance. Total platform cost often 100-500/month - cheaper than Shopify for low-volume stores, similar at scale.
20k monthly revenue. Product cost 40% = 8k. Hosting 50 + plugins 80 + payment 3% (600) + marketing 2k = 2,730 platform + marketing. Profit: 20k - 8k - 2,730 = 9,270 (46% margin). Strong. WooCommerce typically delivers 2-5% better margin than Shopify due to lower platform fees at mid-volume.
WooCommerce advantage: no transaction fee (Shopify charges 2% unless using Shopify Payments), fully customisable, own your data. Disadvantage: requires hosting management, plugin compatibility issues, security responsibility yours. Best for: technical founders, developers, and businesses needing deep customisation. Shopify better for: non-technical operators wanting turnkey.
Quick example
With monthly revenue of 20,000 and product cost of 40% (plus hosting monthly of 50 and plugins monthly of 80), the result is 9,270.00. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.
Which inputs matter most
You enter Monthly Revenue, Product Cost %, Hosting Monthly, Plugins Monthly, and Payment Fee %. Not every input has equal weight. Adjusting one input at a time toward extreme values shows which ones move the result most.
What's happening under the hood
Product cost = revenue × %. Payment = revenue × %. Profit = revenue - all costs. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.
What to do with a low result
A disappointing result is information, not a judgement. Pick the single input that dragged the figure down most and focus the next quarter on that one factor. Breadth-first improvement rarely works; depth-first on the worst input usually does.
What this doesn't capture
The score is a composite of the inputs you provide. Life context — job security, family obligations, health, housing — doesn't appear in the math but shapes the real picture. Use the number as a prompt, not a verdict.
££20,000 - 40% - ££50 - ££80 - 3% - ££2,000 = 9,270.00.

Sources & Methodology
Methodology
This calculator computes monthly store profit by subtracting all operating costs from revenue. It applies the product cost percentage and payment fee percentage to your monthly revenue to determine the cost of goods sold and payment processing fees. The model then deducts fixed monthly costs for hosting, plugins, and marketing from the remaining amount. The calculation assumes these cost percentages and fixed expenses remain constant month-to-month, and treats revenue as the sole income stream. The model does not account for variable costs beyond those specified, tax obligations, seasonal revenue fluctuations, inventory changes, or one-time expenses. Results represent a simplified view of profitability based on the inputs provided.
