What this calculator does
This calculator estimates AdSense earnings from how a page performs: its impressions, its click-through rate, and the cost per click. Enter any three of the four figures, impressions, CTR, CPC, and earnings, and it solves for the one you leave out, so you can project income or work backwards from a target.
How to use it
- Fill in exactly three of the four fields: Page Impressions, Page CTR (%), Cost per Click ($), and Earnings ($).
- Leave empty the one field you want the tool to find.
- Press Calculate to solve for the missing value. Reset clears everything.
The tool needs exactly three meaningful values to work out the fourth, so it will prompt you if you have filled in too few or too many.
How it works
Earnings come from clicks, and clicks come from impressions. A page collects some impressions, a percentage of those viewers (the CTR) click, and each click earns the CPC. Put together:
Earnings = Impressions × (CTR ÷ 100) × CPC
From that single equation, the tool rearranges to solve for whichever field is blank:
- Impressions = Earnings ÷ (CPC × CTR ÷ 100)
- CTR = (Earnings ÷ (CPC × Impressions)) × 100
- CPC = Earnings ÷ (Impressions × CTR ÷ 100)
A worked example
Say a page gets 10,000 impressions, a 2% CTR, and a $0.30 CPC.
The clicks are 10,000 × 2% = 200. At $0.30 each, that is 200 × $0.30 = $60 in earnings.
Through the formula: 10,000 × (2 ÷ 100) × 0.30 = 10,000 × 0.006 = $60.
Getting a number you can trust
One detail decides whether this estimate is useful or misleading: use the CPC from your AdSense report, not an advertiser's bid. Google keeps about 32% of content ad revenue and pays publishers the other 68%, and that cut is already baked into the CPC AdSense shows you. Plug in the advertiser-side figure and the estimate runs high by roughly a third.
Beyond that, treat the result as a ballpark, because real AdSense earnings swing enormously. Your niche matters most (finance and business pages can earn many times what entertainment pages do), then your audience's location (traffic from the US and UK often earns several times more than other regions), then device, ad placement, and the time of year. The metric publishers actually live by is RPM, revenue per 1,000 page views, which already folds in both your click rate and Google's share:
RPM = (Earnings ÷ Impressions) × 1,000
Your true RPM and CPC sit in your AdSense dashboard, and they are far more reliable than any average pulled from elsewhere.
Things to keep in mind
- This is an estimate for planning, not a promise of income, and it is not affiliated with Google. The figure is before tax.
- Use your own AdSense CPC and RPM rather than borrowed averages, since they already reflect Google's revenue share and your specific audience.
- Ads are one piece of the picture. Many sites earn more from affiliate links, sponsorships, or products than from AdSense alone.
Questions people ask
How are AdSense earnings calculated?
From clicks and their value: impressions times the click-through rate gives your clicks, and clicks times the cost per click gives your earnings. This tool runs that calculation and can solve backwards for any missing piece.
Which CPC should I enter?
The CPC from your AdSense report, which is already your share after Google's cut. Do not use the advertiser's bid, or the estimate will be too high, since the 68% publisher share is built into your reported figure.
What are realistic CTR, CPC, and RPM figures?
As rough ranges, CTR is often 0.5% to 3%, CPC anywhere from about $0.10 to several dollars in competitive niches, and RPM from a couple of dollars to $20 or more, all swinging heavily by niche and audience location. Your dashboard gives your real numbers.
Why are my actual earnings different?
Because this is a simple model and real revenue depends on many moving parts: niche, audience country, device, ad placement, season, and how many views actually show ads. Use it to sketch scenarios, and your AdSense reports for the truth.
