ROAS vs ROI?
ROAS is revenue ÷ spend; ROI here is (revenue − spend) ÷ spend.
View-through conversions?
Decide policy before typing revenue.
Blended ROAS?
Sum channels in Excel first, then use totals here.
Margin-aware ROAS?
Subtract COGS externally or use contribution margin fields elsewhere.
Zero revenue days?
ROAS can be zero; that is still informative.
Margin-aware?
Subtract COGS externally for contribution ROAS.
What if one channel is view-through and another is click-only?
Normalize attribution labels before blending. ROAS is only comparable when the numerator and denominator share the same window and credit model.
What does ROAS Calculator calculate in plain English?
