Start with the right revenue number
For business analysis, use Net Revenue after discounts and refunds. This avoids comparing costs against sales that did not ultimately remain in the business. If your platforms use different revenue definitions, keep one consistent methodology so periods remain comparable.
Match costs to the same period
COGS, shipping, payment fees, ad spend and other costs should cover the same calendar period as the revenue being analysed. Otherwise the result can move artificially. Fixed costs can be allocated consistently when you want a broader business profitability view.
Do not confuse the estimate with accounting profit
A profitability dashboard is a business decision tool. It can help explain products, advertising and costs, but it does not replace official accounting records or the statutory tax result prepared from the company books.
What to check in practice
FAQ
Is Estimated Profit the same as accounting net profit?
No. It is a business estimate from available operational data and does not replace official accounting or tax results.
Should fixed costs be included?
Yes when you want a broader business profitability picture, using a consistent allocation method. Contribution analysis can first focus on costs directly related to sales.
