What the defaults give
100,000 impressions at a $5 CPM earns $500.00 a month from impressions.
The same traffic at a 1% CTR and $0.30 CPC adds $300.00 from clicks.
The formulas
CPM revenue = impressions ÷ 1,000 × CPM
Clicks = impressions × CTR%
CPC revenue = clicks × CPC
100,000 ÷ 1,000 × $5 = $500. Clicks: 100,000 × 1% = 1,000, and 1,000 × $0.30 = $300.
Worked examples
100k impressions at $5 CPM → $500
250k impressions at $4 CPM → $1,000
50k impressions at $10 CPM → $500
50k at 2% CTR and $0.50 CPC → 1,000 clicks → $500
500k at $2 CPM, 0.5% CTR, $0.20 CPC → $1,000 + $500
CPM and CPC are alternative models
Most ad networks pay one way or the other for a given placement: display inventory is usually sold by impression under a CPM, while search and some native units pay per click. Adding both, as this tool does, gives an upper bound rather than a forecast — useful for seeing which lever your own numbers depend on, not for predicting a payout. If your network reports an RPM (revenue per thousand impressions), that figure already blends the two and is the number to trust.
What moves real revenue
- Fill rate. Not every impression is sold; unfilled inventory earns nothing regardless of the headline CPM.
- Viewability. An ad below the fold or behind a lazy load may be billed as an impression but valued lower.
- Geography and vertical. CPMs vary by country and topic, often by a factor of ten between the cheapest and most expensive.
- Seasonality. Advertising budgets peak in the fourth quarter, so a January CPM can be half a December one.
- Invalid traffic. Bot impressions are filtered out after the fact, which is why estimated revenue and final payment differ.
Use your network dashboard for the CPM and CTR that were actually paid, and treat this calculation as a way to test how much each lever is worth before changing layout.
The RPM line in most dashboards is the honest figure: it already blends impressions, clicks and unfilled inventory into one number per thousand pageviews. Working from CPM and CPC separately is useful for seeing which lever matters, not for predicting a payment. A page with high impressions and almost no clicks lives or dies on CPM, so ad placement, viewability and the audience geography decide more than the click-through rate.
Frequently Asked Questions
How much does 100,000 impressions earn?
At a $5 CPM, $500. Revenue scales linearly with impressions, so 200,000 impressions at the same CPM earns $1,000.
What is the difference between CPM and CPC?
CPM pays per thousand impressions regardless of clicks; CPC pays per click. Most placements use one or the other, not both.
Should I add CPM and CPC revenue together?
Only as an upper bound. If a network pays one model, adding the other double counts the same inventory.
How is CTR used here?
To estimate clicks: impressions times the click-through rate. A 1% CTR on 100,000 impressions is 1,000 clicks.
What is a good CPM?
It depends heavily on country, topic and season. Display CPMs commonly sit in the low single digits, with premium finance and technology inventory far higher.
Why is my actual payout lower than the estimate?
Because of unfilled impressions, invalid traffic filtering, viewability adjustments and the difference between estimated and finalised CPMs.
