Free Content Marketing ROI Calculator

Content compounds, ads do not

The cleanest way to think about content ROI is to compare it to ad ROI. Ads stop earning the moment you stop spending. A $10,000 Google Ads campaign in March produces clicks in March, then nothing. Content keeps earning for years. A $10,000 article published in March might still drive 30 to 40 percent of its lifetime traffic in year 2 or 3. So ad ROI is a snapshot, but content ROI is a curve. Comparing them straight up at month 6 will always make ads look better and content look broken, even when content is actually winning on a 36-month basis.

The math, top to bottom

conversions      = traffic * conversion_rate
revenue          = conversions * revenue_per_conversion
roi              = (revenue - investment) / investment
cost_per_visit   = investment / traffic
cpa              = investment / conversions
rpv              = revenue / traffic

RPV (revenue per visit) is the cross-channel comparable number. It lets you compare a content visit to a paid visit to a social visit on a dollar-for-dollar basis, even when conversion rates and AOVs differ.

The compounding curve, in one sentence

For SEO content specifically: a typical piece earns roughly 10 to 20 percent of its lifetime traffic in the first 3 months, 30 to 40 percent in the first 12 months, and the remainder over years 2 to 5. Newsletter and social content have the opposite curve: 80 percent of traffic in the first two weeks, almost nothing after. The math in this calculator treats content as a single window, but the strategic implication depends entirely on which curve you are on.

Per-piece economics matter more than averages

Most content portfolios follow a power law: 10 to 20 percent of pieces drive 70 to 80 percent of the traffic. The portfolio ROI hides this. If you produced 30 articles last quarter and 5 of them are doing all the work, the right move is to analyze why those 5 work and double down. The remaining 25 may be dragging the portfolio average down even when the top 5 are wildly profitable. The piece count input on this calculator surfaces per-piece numbers so you can see the average, then go look at the actual distribution in your analytics.

Realistic ROI benchmarks

• SEO blog content, 12 months: 1:1 to 3:1 (most pieces still ranking up)
• SEO blog content, 24 months: 3:1 to 8:1 (compounding visible)
• SEO blog content, 36 months: 5:1 to 15:1 (compounding plays out)
• Gated B2B content (ebooks, reports), 12 months: 2:1 to 5:1 if pipeline tracking is honest
• Newsletter content, 12 months: 5:1 to 20:1, but volume is bounded by list size
• Social content (LinkedIn, Twitter), 12 months: 0.5:1 to 3:1, hard to track honestly because attribution is murky

A worked example

You spent $120,000 on content over 12 months: writers, editor, content tooling, and a third of a marketing salary. You produced 24 long-form pieces. Total content traffic was 180,000 visits. Conversion rate to lead was 1 percent (1,800 leads). Average revenue per lead, factoring in close rate and ACV, is $800 (roughly $200K ACV at a 4 percent close rate). Total revenue is $1,440,000. ROI = (1.44M - 120K) / 120K = 11x over 12 months. CPA = $67 per lead. RPV = $8 per visit. Per piece: $5,000 cost, 7,500 visits, 75 leads, $60,000 revenue. Healthy across the board, with the per-piece number giving you the unit to scale up production confidently.
