Formula and Logic
Paid traffic metrics are calculated using linear spend and fixed conversion rates:
- Total Paid Spend = Monthly Ad Spend × Campaign Duration
- Total Paid Traffic = (Monthly Ad Spend ÷ Cost Per Click) × Campaign Duration
- Paid Conversions = Total Paid Traffic × (Paid Conversion Rate ÷ 100)
- Paid CPA = Total Paid Spend ÷ Paid Conversions (if conversions > 0)
- Paid Revenue = Paid Conversions × Average Order Value (or Customer Lifetime Value)
Organic traffic uses compound growth for traffic volume over time:
- Monthly Organic Traffic = Previous Month Traffic × (1 + (Growth Rate ÷ 100))
- Total Organic Traffic = Sum of monthly traffic over strategy duration
- Organic Conversions = Total Organic Traffic × (Organic Conversion Rate ÷ 100)
- Organic CPA = Total Organic Spend ÷ Organic Conversions (if conversions > 0)
- Organic Revenue = Organic Conversions × Average Order Value (or Customer Lifetime Value)
Practical Notes
When using this tool for business planning, keep these real-world factors in mind:
- Paid traffic delivers immediate results but stops when spend stops, while organic traffic takes 3-6 months to gain traction but compounds over time.
- Organic conversion rates are typically 20-80% higher than paid rates for most e-commerce and B2B businesses, as organic visitors have higher intent.
- Include all organic costs: SEO agency fees, content creation, keyword research tools, and freelance writer rates in monthly organic spend.
- Customer Lifetime Value (LTV) calculations should account for repeat purchase rates, subscription renewals, and referral value for accurate long-term revenue projections.
- Most small businesses allocate 10-20% of revenue to paid acquisition, with organic spend capped at 5-10% of marketing budgets for sustainable growth.
Why This Tool Is Useful
Marketing teams often overspend on paid channels without comparing long-term organic costs, leading to unsustainable budget allocation. This tool models both channels side-by-side, accounting for compound organic growth and LTV instead of just immediate CPA. It helps small business owners justify organic content spend to stakeholders, and lets e-commerce sellers test different growth scenarios before committing budget. You can adjust duration periods to see how organic traffic outperforms paid over 12+ month horizons, a common blind spot in short-term campaign planning.
Frequently Asked Questions
What if my paid and organic conversion rates are the same?
This is rare in practice, but if rates match, compare CPA and long-term sustainability. Paid will deliver faster traffic, but organic will have lower ongoing costs once growth stabilizes. Use the recommended channel output to guide budget allocation based on your cash flow needs.
How do I estimate organic monthly growth rate?
New websites typically see 5-15% monthly growth after 6 months of consistent SEO work. Established sites with strong domain authority may see 2-8% monthly growth. Check your Google Search Console data for historical organic traffic growth to use accurate inputs.
Should I include employee time in organic monthly costs?
Yes, if you or your team spend time on SEO, content creation, or backlink outreach, assign an hourly rate and add that to monthly organic spend. For example, 10 hours of in-house SEO work at $50/hour adds $500 to your monthly organic cost input.
Additional Guidance
Run multiple scenarios with different duration periods to see how organic traffic compounds over time. For example, compare a 3-month paid campaign vs 3-month organic strategy, then rerun with 12-month durations to see long-term differences. If your paid CPA is higher than your customer LTV, that channel is unprofitable regardless of traffic volume. Always cross-check tool outputs with your actual campaign data, as real-world conversion rates may vary based on ad creative, landing page quality, and seasonal demand.
