Estimated Revenue Simulation by Country

Price and costs → profit

Enter price, cost and fees to see profit per unit, monthly profit and break-even.

Quick and detailed change only the cost fields in this step. Monthly revenue is price × monthly quantity, so it is the same in both; monthly profit differs through logistics, channel fees and duty (the detailed estimate also uses initial investment for the payback period).

Confidence Low

Of the 9 values used, 4 are from official sources, 0 are your inputs, 0 are from your application, 1 are estimates and 4 are samples. Confirmed values (official sources + your inputs + application values) make up 44%. Enter 4 of your own values to raise it → selling price · unit cost · logistics cost · monthly units

Rule: High if confirmed values are 80% or more, Medium if 50% or more, Low otherwise. This screen cannot check whether your own inputs and application values are correct.

Participants

Add participants

Press “Add participant” and enter the brand, investors and partners with their shares and investments to calculate the split.

How the split is calculated
  • By share: each participant's amount = monthly profit × share %. Shares must add up to 100%.
  • Revenue fee: partner amount = monthly revenue × fee % (split equally if there are several partners). The remaining profit (monthly profit − partner amount) is split by share among non-partner participants. If it is negative, the amount is shown separately as a shortfall.
  • Capital first: each month's profit ① repays unreturned investment in proportion to what each paid, ② then repays the accrued preferred return if any (annual %, simple interest, on unreturned investment), ③ and the rest is split by share among all participants.
  • Months with zero or negative profit have nothing to split. Corporate tax, withholding and contract fees are not included.
  • Investment returned = the first month the participant's cumulative amount reaches what they invested.
