Model store profit after BigCommerce plan costs, payment-provider fees, COGS, fulfillment, ads, returns, apps and overhead — with break-even CPA and ROAS.
Editable planning assumptions. Verify current fees against your account, product and platform terms.
This models profit using shipping costs you enter. It does not request live carrier rates or quote delivery charges.
Editable assumptions — match your actual provider and BigCommerce agreement.
Editable planning assumption. Verify the applicable threshold/contract before using this cost.
The calculator above turns a selling price into per-order and monthly economics. Enter product cost, fulfillment, advertising, payment processing, returns, apps and other overhead, then choose the BigCommerce plan assumptions that match your store. The summary card stays beside the inputs on larger screens so you can watch net profit, margin, ROI, break-even CPA, break-even ROAS and total cost change as one assumption moves. Treat the presets as a starting point, not a quotation: BigCommerce plan rules, GMV thresholds, provider status and merchant-specific payment pricing can change the result.
The model separates revenue from every cost required to produce and acquire the order. Monthly platform and app costs are allocated across the entered order volume so a fixed subscription becomes a comparable per-order cost.
Break-even ROAS is a planning threshold, not a campaign guarantee. If costs such as returns or processing fees rise, the maximum ad cost falls and the required break-even ROAS rises.
Suppose an order sells for $60. Product cost is $18, fulfillment is $6, advertising costs $12, and other variable costs are $1.50. If payment processing is modeled at 2.89% + $0.29, the payment charge is about $2.02. A 3% returns reserve adds $1.80. If $105 of monthly platform cost is allocated across 300 orders, that contributes $0.35 per order before any open-provider or app charges. Under those assumptions, total modeled cost is about $41.67 and net profit is about $18.33, or roughly a 30.6% margin. Changing only the provider type can materially change the result, which is why the provider fee remains editable.
| Published 2026 plan | Monthly price | Annual-billing equivalent | Open Payment Provider fee |

| Growth | $105 | $79/mo | 1.0% |

BigCommerce introduced the Core, Growth, Scale and Performance structure effective June 1, 2026. Scale also uses a published GMV overage model. Verify current terms on the official BigCommerce pricing page before relying on any preset.
No. Your effective platform cost depends on plan, GMV, provider type and account terms. Use the editable assumptions shown in your account.
It is an additional BigCommerce fee that can apply to eligible orders processed through Open Payment Providers on self-service plans. Published rates vary by plan.
Yes. Processor charges are separate from platform-plan or provider fees, so enter the actual rate and fixed charge from your provider.
No. The calculation compares monetary assumptions only. Features, support, contract terms and operational requirements can justify a different plan.
Enter a carrier or fulfillment quote as a shipping assumption. This calculator is not connected to a live checkout-rate engine and should not be treated as an automatic carrier-rate estimator.
Compare platforms using the same product cost, order value, payment mix, fulfillment and monthly volume. The store-cost guide demonstrates fixed-cost allocation and a hypothetical payment-rate savings threshold.
