Profitability Calculators
The arithmetic underneath a business that works: what a sale is worth once the variable costs come off, and what that leaves you to spend on winning the next one.
Profit Margin Calculator
What one sale actually leaves you: gross margin, profit per unit and the return your campaigns have to clear.
AOV Calculator
What one order is worth on average — and how much of it you can hand to acquisition and still make money.
Conversion Rate Calculator
The share of your traffic that acts — and the cheapest number to move once the clicks are already paid for.
Statistical Significance Calculator
Is your test result real or chance? Check two variants for statistical significance — the two-sided p value, the confidence it clears, and the relative uplift.
ROI Calculator
Return on investment for any measure at all, not just marketing — from what it earned and what it cost, plus the annualized figure that lets you compare periods.
Break Even Point Calculator
How many units a product has to sell before it stops losing money — your fixed costs divided by the contribution margin each unit leaves behind.
Reverse Margin Calculator
Which price does your target margin actually require? Enter unit cost and the margin you want, and get the price, the gross profit it leaves, the break even ROAS and the markup it corresponds to.
From margin to profit: reading these numbers in order
This category answers the least glamorous question there is: does anything survive at the end? The order to read it in runs upwards. Gross margin comes first, because it decides what a single sale leaves you once the goods are paid for — and because every ceiling further up is derived from it rather than chosen. Order value then sets how much of that margin one transaction actually delivers, and conversion rate sets how many transactions a given amount of traffic produces. Only with those three fixed does a return figure mean anything: the same 2x return is comfortable at a 60 % margin and ruinous at 20 %. A number that looks healthy in a dashboard has usually skipped one of these steps.
