Ecommerce Category Revenue Calculator

What this number means

Monthly revenue is search volume x rank CTR x conversion rate x order value. At the defaults - 20,000 searches, rank #3 (10% CTR), 2.5% conversion, $85 AOV - that is $4,250/month ($51,000/year).

Gross profit ($1,700/month at 40% margin) is what the ranking contributes after product costs. Traffic value ($5,600/month) is what the same 2,000 clicks would cost in Google Ads - the check that organic is earning its keep versus paid.

The formula

In plain English: searches become clicks, clicks become orders, orders become revenue.

• Rank CTR from the curve (1: 27%, 2: 15%, 3: 10%, 4: 7%, 5: 5.5%, 6: 4.5%, 7: 3.5%, 8: 3%, 9: 2.5%, 10: 2%, 11-20: 1%)
• Clicks = Search volume x Rank CTR
• Orders = Clicks x Conversion rate
• Monthly revenue = Orders x Average order value
• Gross profit = Revenue x Margin; Traffic value = Clicks x CPC; Annual revenue = Monthly x 12

Worked example

A footwear retailer targets rank #3 for a category keyword with 20,000 monthly searches. At a 10% CTR that is 2,000 clicks; at a 2.5% conversion rate, 50 orders; at $85 AOV, $4,250/month in revenue and $1,700/month in gross profit. The same clicks would cost $5,600/month in Ads.

The cumulative chart shows $51,000 stacking up over a year at a steady rank - the number that justifies the link-building budget for the category page. If links cost $8,000 to win the ranking, the payback is under two months of profit.

Assumptions and limitations

• One keyword, one page. Real category pages rank for hundreds of keywords; this models the head term only.
• Conversion rate is the fragile input. Category conversion varies wildly by price point and intent - use your measured rate.
• Rank is assumed steady. No ramp-up period or ranking volatility is modeled; new pages take months to reach target rank.
• Margin is gross. After shipping, returns, and overhead, net profit is lower.
• All figures are planning estimates.
