How the calculator works
Use the math to ask a better question.
(Illustrative incremental gross contribution − program cost) ÷ program cost × 100
01A mathematical scenario does not prove the process caused incremental sales.
02Use signed attribution rules, baseline exclusions, campaign evidence, and actual collections.
03Capacity, eligibility, refunds, and fulfillment cost can make real results lower or zero.
Useful context
Questions worth answering first.
What are percentage points?
Moving from 25% to 28% is an increase of three percentage points—not a 3% relative increase.
Does this prove a campaign caused the sale?
No. Causation requires the approved segment, attribution window, exclusions, campaign evidence, and collection records agreed in writing.
