Shopify Profit Calculator
Shopify net profit after all fees.
Calculate Shopify store monthly profit from revenue, product cost percentage, plan tier, transaction fees, ad spend, and other costs.
What this tool does
This calculator estimates your store's monthly net profit by deducting all major operating costs from revenue. It accounts for product cost as a percentage of sales, your Shopify plan fee, payment processing fees, advertising spend, and any additional operating expenses you enter. The result shows both your net profit in local terms and the net margin percentage—how much profit remains from each unit of revenue after all deductions. Revenue and product cost percentage typically have the largest impact on the final figure. A typical scenario might involve a store with seasonal revenue fluctuations wanting to model profitability under different ad spending levels. Note that this calculation doesn't include income tax, shipping costs if separate from product cost, refunds, chargebacks, or variable staffing expenses—it's designed for educational illustration of how different cost inputs affect bottom-line profit.

Shopify stores look simple on the surface but the profit maths stacks up fast. You pay Shopify a monthly plan, transaction fees on every sale (usually 2% if you don't use Shopify Payments), product cost, ad spend, and other costs like apps and shipping software. What's left is profit - and for most small stores, it's less than operators expect.
30k monthly revenue with 40% product cost, 29 Basic plan, 2% transaction fees, 3k ads, and 500 other apps = 13,871 profit, around 46% net margin. That's strong. Most Shopify stores that disclose numbers sit at 5-15% net margin because ad spend eats 20-30% of revenue on cold-traffic stores.
The biggest cost variable is ads. Facebook and Google ad costs have doubled since 2020 for most product categories. Stores relying on paid acquisition without email/SMS retention often see profit disappear as CPMs rise. Stores that build returning customer bases can push net margin to 20-35% because repeat customers carry no acquisition cost.
Run it with sensible defaults
Using monthly revenue of 30,000, product cost of 40%, shopify plan of 29, transaction fee of 2%, the calculation works out to 13,871.00. The defaults are meant as a starting point, not a recommendation.
The levers in this calculation
The inputs — Monthly Revenue, Product Cost %, Shopify Plan, Transaction Fee %, and Ad Spend Monthly — do not pull with equal force. Not every input has equal weight. Adjusting one input at a time toward extreme values shows which ones move the result most.
How the math works
Product cost = revenue × product %. Transaction fees = revenue × fee %. Net profit = revenue - product cost - plan - transaction fees - ads - other.
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.
££30,000 revenue - 40% products - ££29 plan - 2% fees - ££3,000 ads = 13,871.00.

Sources & Methodology
Methodology
The calculator computes monthly net profit by subtracting all costs from revenue. Product costs are modelled as a percentage of revenue, as are payment processing fees. The net profit figure equals total revenue minus product cost percentage, minus the fixed monthly plan fee, minus the transaction fee percentage, minus advertising spend, and minus any other operating costs entered. The model treats all percentages as applied to the same revenue figure and assumes costs occur simultaneously within each month. It does not account for payment processing delays, refunds, seasonal variation, tax obligations, shipping costs, or changes in cost structure over time.
