From menu to clarity
Add weekly fixed costs, billable hours, percentage costs, and your own hourly return target.
Enter price, representative duration, and consumables. Marginelle keeps every assumption visible.
See exact target gaps, then compare immutable audits after costs, time, or prices change.
Price is only the first number
Two services can charge the same price and leave very different hourly returns once time, products, card fees, and weekly overhead are considered.
Marginelle shows the estimate without pretending to know your market, your taxes, or the right price for your business.
($110 − $3.30 − $12 − $16.67) ÷ 120 × 60 = $39.02/hourSame kind of price. A very different hour.
