Formula Used
- Ad Opportunities = Pageviews × Ad Slots per Page
- Served Impressions = Ad Opportunities × Fill Rate
- Viewable Impressions = Served Impressions × Viewability Rate
- Estimated Clicks = Viewable Impressions × CTR
- Invalid Clicks = Estimated Clicks × Invalid Click Rate
- Valid Clicks = Estimated Clicks − Invalid Clicks
- Gross Billable Revenue = Valid Clicks × Average CPC
- Platform Fee Amount = Gross Billable Revenue × Platform Fee Rate
- Pre Tax Revenue = Gross Billable Revenue − Platform Fee Amount
- Tax Amount = Pre Tax Revenue × Tax Rate
- Net Revenue = Pre Tax Revenue − Tax Amount
- Profit = Net Revenue − Operating Cost
- Net RPM = (Net Revenue ÷ Pageviews) × 1000
- Served eCPM = (Gross Billable Revenue ÷ Served Impressions) × 1000
- Break Even Clicks = Operating Cost ÷ [CPC × (1 − Fee Rate) × (1 − Tax Rate)]

Frequently Asked Questions
1) What does this calculator estimate?
It estimates billable clicks, revenue losses from invalid traffic, deductions, net revenue, profit, RPM, eCPM, and forecasted earnings for a chosen period.
2) Why is viewability included?
Viewability reduces the number of impressions that can realistically generate clicks. Using it helps produce a more conservative and performance aware revenue estimate.
3) What is invalid click rate?
It represents clicks filtered because of fraud, bots, accidental activity, or quality controls. A higher rate reduces valid clicks and billable revenue.
4) Should CPC be gross or net?
Use the billable CPC before platform fees and taxes. The calculator handles deductions later, so net earnings remain visible and easier to audit.
5) What does net RPM mean here?
Net RPM shows how much net revenue is earned per 1,000 pageviews. It helps compare monetization strength across sites, pages, or campaigns.
6) Why can profit become negative?
Profit becomes negative when operating costs exceed net revenue. That usually signals weak CPC, low CTR, poor fill, poor viewability, or heavy deductions.
7) Can this calculator support scenario planning?
Yes. Change CTR, CPC, invalid rate, fees, or costs to test optimistic and conservative monetization cases before making inventory or traffic decisions.
8) Is this only for display advertising?
No. It can also help evaluate search ads, native ads, sponsored widgets, or affiliate click flows when revenue is primarily click based.
