Most published YouTube earnings figures are wrong, usually because they quote CPM as though it were income. Estimating your own earnings accurately is straightforward once you know which number to start from and what reduces it.
Start with RPM, never CPM
This single distinction accounts for most bad estimates.
- CPM — what an advertiser pays per thousand ad impressions, before YouTube’s share.
- RPM — what you actually receive per thousand views of your video, after the revenue share and including unmonetised views.
RPM is the number that describes your income. When a video quotes an impressive CPM, that figure has not yet had YouTube’s 45% removed, and it ignores every view that carried no ad.
Find yours in YouTube Studio under Analytics → Revenue. It is specific to your channel and far more useful than any published average.
The calculation
Once you have RPM, the arithmetic is simple:
(Monthly views ÷ 1,000) × RPM = estimated monthly ad revenue
Our YouTube Earnings Calculator runs this with niche-typical ranges when you do not yet have your own RPM, and the CPM and RPM Calculator converts between the two figures.
Treat any output as a range. Ad revenue varies enough month to month that a single precise figure is misleading by construction.
What moves the number
Niche
The largest single factor. Finance, software, insurance and business content attract advertisers with high customer values. Entertainment and general lifestyle content attract lower bids. The gap between them is wide.
Audience geography
Advertiser rates differ substantially between markets. A channel with a large share of viewers in major advertising markets earns more from identical view counts.
Video length
Videos over eight minutes support mid-roll ads, which raises RPM. This is a genuine effect, but padding a short topic to reach the threshold damages retention — and retention drives the distribution that generates views in the first place.
Season
Rates climb through the final quarter, peak in December and fall sharply in January when advertising budgets reset. A January decline is expected and is not a channel problem.
Advertiser suitability
Videos limited or excluded from advertising earn less regardless of performance. Check the monetization status on individual videos if revenue looks inconsistent with views.
What the calculation leaves out
Ad revenue is one stream of several, and for most channels it is not the largest.
A sponsorship on a single video can exceed a month of ad revenue. Affiliate income frequently outperforms ads per viewer. A digital product carries no revenue share at all.
So an earnings estimate based on views describes your smallest and most volatile stream. It is useful for planning, but it is not a measure of what a channel is worth.
Estimating someone else’s earnings
You cannot do this accurately, and published estimates for individual creators should be treated as guesses.
Their RPM depends on audience geography, niche, video length and advertiser suitability — none of which is public. Third-party estimate tools typically apply a generic rate to public view counts, which produces ranges wide enough to be meaningless.
The short version
Use RPM, not CPM. Take your own RPM from Studio rather than a published average. Treat the result as a range, expect a January fall, and remember it describes only ad revenue — usually the smallest part of what a channel earns.
