The most common marketing calculation. Enter last month's value and this month's value to see the percentage change. Works for revenue, traffic, conversions — anything you track over time.
Margin and markup are different numbers from the same data. Margin divides profit by revenue; markup divides profit by cost. A 50% markup is a 33% margin. Mixing them up is one of the most common errors in ad-spend planning — the break-even ROAS shifts significantly depending on which one you use.
Uplift is the percentage change between a control and a variant — the same formula as percentage change, but named differently in experiment contexts. Use this mode when reporting A/B test results or comparing campaign performance against a baseline.
