Demand Generation
The Honest Math of Demand Gen ROI
Most demand gen ROI calculations are fiction. Here is how to do the math honestly.
Demand gen ROI calculations are usually a fiction told by marketing leaders to defend their budget. The standard formula (pipeline created divided by marketing spend) ignores attribution complexity, time lag, and the difference between sourced and influenced pipeline. The result is a number that looks good and means little.
The honest math has four components. First, pipeline attribution model (multi-touch, not last-touch). Second, time lag (the campaigns running today produce pipeline that closes 6-18 months from now; the formula needs to compare current spend to current revenue from past spend). Third, channel mix attribution (paid programs typically over-credit themselves; brand and content under-credit). Fourth, decay curves (some channels produce immediate pipeline; others compound over years).
The honest report to the board: pipeline created this quarter (with attribution split by source), revenue closed this quarter from pipeline created in past quarters (with attribution split by source), forward-looking forecast based on current pipeline coverage and historical conversion, and channel mix recommendation based on the above.
The teams that report this way build long-term credibility with the board because the numbers reconcile to revenue over time. The teams that report inflated single-quarter ROI numbers eventually face the reckoning when revenue does not match. Pick the long game.
