Content Marketing Calculator

Monthly Cost Per Lead only counts the leads that one month's content generates in its own first month, while Lifetime Cost Per Lead spreads the same one-time production cost across every month that content keeps generating traffic over its full lifespan. Since content usually earns traffic for many months after publication, the same cost divided by a much larger total lead count produces a dramatically lower lifetime figure.

It's the average number of months a typical piece of your content keeps generating meaningful organic traffic before it goes stale, gets outranked by newer content, or becomes outdated. Reviewing your own site's analytics for how long older articles keep earning consistent traffic — rather than guessing — gives a more accurate lifespan estimate than a generic assumption.

No — the monthly figures represent only what one month's newly published content generates in its own first month, not the combined traffic from every piece still live from prior months. A mature content library with months or years of accumulated pieces still earning traffic will see meaningfully higher total monthly traffic than this single-month snapshot suggests.

The projection assumes steady traffic per piece and a fixed content lifespan, but real content performance varies widely — some pieces go stale faster than expected due to search ranking changes or shifting topic relevance, while others outperform and keep earning traffic well beyond a typical lifespan. Use the lifetime projection to compare pieces and set a budget, not as a promise of what any single piece will actually earn.

Both traffic and conversion rate multiply directly into the lead count, so doubling either one roughly doubles monthly leads and lead value, all else equal. In practice, improving conversion rate on existing content — through better calls to action or landing pages — is often cheaper than producing enough additional content to double traffic, making it a common first lever for improving content ROI.
