About this calculator

Content marketing ROI is one of the slowest, fuzziest, but most-compounding investments available to ecommerce. A single blog post that ranks #1 for a relevant keyword can deliver traffic for 5+ years at zero ongoing cost. But the upfront investment-to-payback gap is long enough that many operators quit before content economics turn positive.

This calculator models the typical content lifecycle: 6-12 month ramp to peak traffic, then steady-state revenue contribution for years afterward. The math compounds because each new post adds to a portfolio of existing ranking content. Month 12 of a content program produces dramatically more traffic than month 3, even at constant publishing pace.

The key inputs are honest cost per post (don\'t exclude employee time or research overhead) and realistic conversion rate from blog readers (typically 0.3-1.5% — much lower than commercial-intent traffic, but with much lower acquisition cost). Multiply traffic × CR × AOV to get monthly revenue per post, then divide by cost-per-post to find payback period.

Content economics work when the portfolio compounds. After 12 months of 4 posts/month, you have 48 posts averaging maybe 200 visitors each = 9,600 monthly organic visitors. After 24 months, 96 posts × 200 = 19,200 visitors. Same monthly investment, doubled output. Pair this with the SEO Traffic Revenue Estimator and the Organic vs Paid Cost Comparison for fuller content ROI modeling.

Frequently asked questions
How long until a blog post pays back?
Most posts take 6-12 months to reach peak traffic. The payback period from a single post is usually 12-24 months at typical content-creation costs ($300-1,500 per post depending on quality tier). Posts that rank for high-intent commercial keywords can pay back in 3-6 months; informational posts often take longer.
What's a typical content cost?
Junior writer: $50-150/post. Mid-tier freelancer: $200-500/post. SEO-optimized agency content: $500-1,500/post. Internal content (loaded with employee time): often $1,000+ when fully accounted for. The economics work better with higher-quality content because lifetime traffic is multiples higher.
How do I attribute revenue to blog content?
Three methods. Best: assist conversion attribution showing blog as a touchpoint in the path. Good: pre-blog vs post-blog organic traffic to the rest of the site (incremental traffic × site CR × AOV). Crude: count blog readers who later become customers (look for branded search lift after content publishes).
Should every blog post be profitable on its own?
No. Treat content as a portfolio. 20% of posts will produce 80% of traffic. Some posts will rank #1 and generate $50K+/year; many will get 50 visits/month forever. The portfolio works if average post pays back; trying to make every post a winner means abandoning content too early.
When should I stop investing in content?
When 12-18 months of consistent posting hasn't produced any ranking or assist conversions. That signals a domain/niche/strategy problem, not a content-quality problem. Switch to a different angle (different keywords, different content format) before quitting entirely.
