Formula Used

CTR = (Clicks ÷ Impressions) × 100
Lead Capture Rate = (Leads ÷ Clicks) × 100
Lead Qualification Rate = (Qualified Leads ÷ Leads) × 100
Close Rate = (Customers ÷ Qualified Leads) × 100
Click to Customer Conversion Rate = (Customers ÷ Clicks) × 100
CPC = Ad Spend ÷ Clicks
CPL = Ad Spend ÷ Leads
CAC = Ad Spend ÷ Customers
ROAS = Revenue ÷ Ad Spend
Gross Profit = Revenue × Gross Margin Percentage
Net Profit = Gross Profit − Ad Spend − Fixed Costs
ROI = (Net Profit ÷ Total Costs) × 100
Required Customers at Target = Clicks × Target Conversion Rate

Frequently Asked Questions

1. What is a marketing conversion rate?

It measures how many users complete a desired action. The action could be a lead, signup, trial, or customer purchase, depending on your campaign goal.

2. Why should I enter qualified leads separately?

Qualified leads show funnel quality, not just volume. They help you understand whether poor sales come from weak targeting, weak lead quality, or poor closing performance.

3. What does click to customer conversion rate show?

It shows the percentage of clicked visitors who became customers. This is often the most practical end-to-end rate for paid traffic analysis and landing page evaluation.

4. Why are CPC, CPL, and CAC all useful?

Each metric reflects a different funnel stage. CPC measures traffic cost, CPL measures lead generation efficiency, and CAC measures the final cost to gain a paying customer.

5. Can ROAS be good while ROI is poor?

Yes. ROAS only compares revenue against ad spend. ROI also considers gross margin and fixed costs, so profit can still be weak even when revenue looks strong.

6. What if my funnel numbers do not follow the normal order?

The calculator still computes results, but it shows review notes. Funnel stages usually decline from impressions to customers, so unusual jumps may signal tracking issues.

7. How often should I update campaign data?

Update it whenever your reporting period changes. Daily checks help active campaigns, while weekly or monthly reviews suit longer campaigns and strategic comparisons.

8. Can I use this calculator for channel comparison?

Yes. Run the calculator separately for each source, such as search, social, email, or retargeting. Then compare rates, costs, returns, and target gaps side by side.
