Your Details

Overview

Use this Sales Funnel CPM Calculator to estimate how a CPM-based ad campaign could move people through your funnel. Enter your ad spend, CPM, click-through rate, landing page conversion rate, lead-to-customer rate and average revenue per customer to project customers, revenue and return.

How it works

The calculator starts by converting your ad spend and CPM into estimated impressions. It then applies your click-through rate to estimate clicks, your landing page conversion rate to estimate leads, and your lead-to-customer rate to estimate customers. Finally, it multiplies customers by average revenue per customer to estimate revenue, then compares that revenue with ad spend to show profit and ROAS.

Frequently asked questions

What does this calculator estimate?

It estimates impressions, clicks, leads, customers, revenue, profit and ROAS from a CPM-based advertising campaign.

What is CPM?

CPM means cost per mille, or the amount you pay for 1,000 ad impressions.

How is revenue calculated?

Revenue is estimated by multiplying projected customers by your average revenue per customer.

Does profit include all business costs?

No. The profit shown here subtracts ad spend only and does not include other overhead, tools, payroll or fulfilment costs.

What is ROAS?

ROAS stands for return on ad spend. It is calculated as revenue divided by ad spend and shown as a multiple.

Why do small conversion rate changes matter so much?

Because each stage of the funnel multiplies the next, even a small improvement or drop in CTR or conversion rate can significantly change final customer and revenue estimates.
