"I want this much profit per month." Farolane works backwards to units, ad budget, and break-even price on each channel — with ad costs shown as ranges from public benchmarks (override with your actuals anytime).
What it would take to hit the whole goal on each channel individually.
Net per unit before ads comes from the same engine as the comparator. We then estimate customer acquisition cost as CAC = CPC ÷ conversion rate using quarterly-updated benchmark ranges — worst case pairs high CPC with low CVR, best case the opposite. Units needed = goal ÷ net-after-ads; ad budget = paid units × CAC. If your worst-case net after ads is negative, the plan is flagged: raise price, cut costs, or lean on organic share.
Because a single predicted CAC is fiction. Benchmarks are averages across thousands of advertisers; your creative, niche, and account history move the real number. Plan against the range, then replace it with your actuals using the override fields.
