Content Marketing ROI Calculator
What a piece of content returns — over its whole life, not its first month — with the cost per lead and the break-even traffic it needs.
Content is an asset with a long tail.
How the content marketing roi calculator works
Content is an asset with a long tail. A post that draws 500 visits a month for three years delivers 18,000 visits from one production cost, which is why first-month ROI is a useless measure of it.
The calculation compounds monthly traffic over the content's useful life, applies the conversion rate and margin, and compares against production cost. The decay rate matters: evergreen content holds its traffic, news content loses almost all of it within weeks.
Formula: lifetime value = Σ(monthly traffic × decay^n) × CR × AOV × margin
Worked examples
| Inputs | Lifetime ROI | Note |
|---|---|---|
| A 1,500 piece drawing 500 visits a month | 1,062.77% | strongly positive over three years |
| Fast-decaying news content | 74.3% | far less lifetime value |
| Expensive production | 118.02% | may never break even |
FAQFrequently asked questions
Why measure content over its lifetime?
Because a piece keeps working. Judging it on its first month is like judging a building on its first month of rent.
What is a realistic decay rate?
Evergreen how-to content often holds flat or grows for years; news and trend pieces lose 20 to 40% a month. The difference dominates the result.
How much should a piece cost?
Whatever it takes to be the best answer to the query. The break-even row shows what that cost demands in return.
Why does the first-month ROI look terrible?
Because the whole production cost lands in month one against a single month of traffic. It is a real number and a misleading one.
What if it never ranks?
Then the return is zero regardless of quality. Most content programmes fail on distribution and search intent rather than on writing.
