Clear answers before you trust the math.
How the free calculators work, what the $19 Profit Action Report adds, where AI fits, and what Profit Per Order does — and does not — claim.
What people usually want to know first.
If your question is about a specific formula, open that calculator: every calculator also has its own formula notes, worked example and limitations.
Read the methodology →What is Profit Per Order?+
Profit Per Order is a set of free ecommerce unit-economics calculators for decisions around margin, pricing, fees, advertising, sourcing, shipping, returns and inventory. The goal is to make the assumptions and formulas visible instead of hiding them behind a score or opaque dashboard.
Are the calculators really free?+
Yes. The public calculators do not require an account and the core calculations are free. You can edit the assumptions, rerun scenarios and inspect the formula notes without buying anything.
What does the $19 Profit Action Report add?+
The one-time report saves one calculator scenario, checks the inputs, ranks modeled opportunities, adds sensitivity tests and guardrails, and turns the result into a practical action plan and seven-day sprint. It does not unlock a different version of the calculator math.
Is the Profit Action Report a subscription?+
No. It is a one-time purchase for one saved scenario. There is no recurring subscription required for the $19 report.
Does AI calculate my profit or change the numbers?+
No. Financial outputs come from deterministic Python formulas. When the optional report narrative uses AI, it receives the completed calculation and is instructed to organize findings and actions without changing the calculated numbers.
How accurate are the fee rates and defaults?+
Defaults are planning assumptions, not promises. Rate fields stay editable, source pages and verification dates are published, and the source-monitoring workflow is designed to flag material changes. Replace defaults with your own invoices, statements and current platform terms whenever possible.
Is Profit Per Order accounting, tax, legal or investment advice?+
No. The outputs are planning estimates for operating decisions. Taxes, accounting treatment, legal obligations and platform-specific rules can depend on facts the calculator does not know, so material decisions should be verified with the relevant professional or official source.
What data do I need to provide?+
The free calculators do not require an account. You enter the operating assumptions needed for the calculation. Private paid-report delivery uses the checkout email supplied through Stripe. The privacy policy explains optional measurement, internal test traffic and retention in more detail.
Why focus on profit per order instead of gross margin?+
Gross margin can omit costs that change with the order, such as payment fees, fulfillment, shipping subsidy, expected returns and acquisition. Profit-per-order and contribution views make those variable costs explicit so a sale that looks healthy at gross margin does not get mistaken for a scalable order.
Question the assumption.
If a formula, source or report scope is unclear, send the exact question. We can check it against the methodology or source registry without turning the answer into a sales pitch.
