It's not clear to me what you are asking, but if your question has a definite answer and it relates to Youtube as a business, I can probably help answer. Youtube has been my full-time job for years.

About Premium generally, if you can afford it and you are considering it, there is no reason to hesitate. I say that both as a channel owner and as someone who pays for Premium every month. You never see an AdSense ad again, and you make that happen while still supporting the channels you enjoy. Pretty win-win, IMO.

Two things that most people don't know about Premium:

1. On a per-view basis, Premium views are actually 'worth more' than ad-watching views. We're talking tiny fractions of a cent, but they add up.

2. Most so-called "demonetized" views remain eligible for Premium revenue.

the amount matters to me

if the creators only get 1c/month from my premium and google get the lion's share I'll continue to block ads and support via patreon/merch instead

I doubt there is a set amount assigned. It would be weird and hard to calculate. User A watched 3 videos so their views are worth 1 dollar, user B watched 300 videos so their view is worth a cent. It’s far more likely that a premium user view is worth 1 cent and a normal user is worth .5 of a cent. So the amount going to creators would depend on how much you viewed (and how long)

Agree, in the UK the service is overpriced (exchange rate?) and bundled with Youtube Music subscription service for an extremely unpalatable 1.99 GBP per month.

How much of that money is just paying for music licensing I don't want or need?

Is this a serious comment that 1.99 is overpriced for unlimited content?

The subscription costs me $12/month. If my goal is to support creators, I’d like to understand what portion of that subscription is actually going to the creators, versus Google.

It sounds like the answer to that is “very little” since you mentioned fractions of a cent per view. So if I watch a few dozen videos from a single creator in a month, can I safely assume they’ll get a couple cents that month from me?

I get that it adds up, otherwise the creators wouldn’t bother creating for the platform, but I’m not sure that helps me justify paying Google another $11.96 a month.
