What this calculator does

The break-even CPC calculator helps estimate the highest cost per click you can afford before your ads stop breaking even.

It is useful for:

Formula

Break-Even CPC = Average Order Value × Conversion Rate × Gross Margin

Where:

• Average Order Value = average revenue per order
• Conversion Rate = percentage of clicks that become orders
• Gross Margin = profit margin available before ad costs
• Break-Even CPC = maximum affordable cost per click before profit is eliminated

Example calculation

If:

• Average order value = 1500
• Conversion rate = 2.5%
• Gross margin = 40%

Then:

• Revenue per click = 1500 × 0.025
• Revenue per click = 37.50
• Break-even CPC = 37.50 × 0.40
• Break-even CPC = 15.00
