How to calculate content marketing ROI
Each month creates a new content cohort. Every piece ramps toward mature traffic, remains undecayed through age six, then compounds monthly decay until its lifespan ends. Program revenue comes from all active cohorts. Contribution profit equals revenue × gross margin, and ROI compares cumulative contribution profit with cumulative program cost.
Content ROI by piece and program
One-piece economics use the same lifespan curve. Estimated cost per piece allocates one month of program cost across that month’s production. The chart compares cumulative program contribution profit with cumulative program cost, not one piece with the recurring budget.
Frequently asked questions
How is content marketing ROI calculated?
Each month creates a new content cohort. Active cohorts generate incremental sessions. Added revenue equals sessions × conversion rate × customer value. Profit after direct costs (contribution profit) equals revenue × gross margin. Program ROI equals (cumulative contribution profit − cumulative program cost) ÷ cumulative program cost.
How are one-content-piece economics calculated?
One piece uses the same ramp, no-decay period through age six, compounded decay, and lifespan. Piece ROI equals (lifetime contribution profit − estimated cost per piece) ÷ estimated cost per piece. Estimated cost per piece allocates one month of program cost across that month’s production.
What happens when a piece reaches its lifespan?
That piece stops contributing traffic. Older cohorts can expire while newer monthly cohorts continue to ramp.
What happens with zero production or zero cost?
Zero production gives no traffic or revenue while costs accumulate. A 0% gross margin is valid and produces $0 contribution profit. With zero program cost, traffic and contribution still calculate, but ROI, break-even, allocated cost per piece, and piece ROI show N/A.
