The total valuation of those 511 is currently about $11.5 billion.
We ourselves don't know the percentage owned by founders. But considering that investors continually complain that YC companies are overpriced, it may be higher than the industry average.
I find it interesting that the current average valuation of a YC company is 22.5 million which is almost identical to what it was 2 years ago when there was 210 companys "the average value of startups we've funded is about $22.4 million" http://ycombinator.com/nums.html
That is interesting. The reason it hasn't changed is convertible notes. Now most of the fundraising immediately after Demo Day is on notes. Since a note doesn't establish a valuation, we add zero to the total valuation for those companies. So the number you get by dividing the total valuation by 511 ends up being pretty conservative; it's equivalent to assuming all the companies that have raised money on notes will go out of business.
The average valuation of the 268 of those 511 companies that have valuations (by being acquired, raising an equity round, or going out of business, in which case it's zero) is $43 million.
Why not use the valuation cap on the note (in cases where there is one) in place of the valuation? Is there a reason you wouldn't consider it equivalent to a valuation for the purposes of a rough calculation like this?

Isn't it almost always going to be the case that the founders got diluted by the same proportion as you did? In which case, based on your comment below of YC being diluted from about 6% to about 3%, presumably the founders (who started out owning almost all the stock) would now be around 50%.
I feel like I must be missing something obvious here.
That's an estimate of what will happen eventually in the biggest companies, based on industry norms. But we don't know how much we've been diluted so far in individual companies.
Bah. They're not "overpriced" as long as someone is willing to pay the price. Startup pricing is about as close to a frictionless transaction as we're going to see. What they're actually complaining about is that the YC companies are getting better terms from investors, thanks to PG/YC's deliberate efforts to shift the balance of power in favor of the founders. I'm not crying tears for them. They don't like the terms, they're welcome to walk away from the table.
So arguably at least one of {pg, pb, etc.} could have made just as much value over the past ~10 years by starting another startup, instead of an YC, if that were the goal. 10 years is probably enough time to try/fail-fast at least 2 and maybe 4 times, each.
Probably, but you're only counting the tangible value. In my mind what they've done is far greater in intangible value. What about HN and the community it has nurtured? And let's not forget being a sort of pointer to true north to most of the people thinking of creating something out of nothing. Sure, money is easy to count and imagine, but there's plenty of people that make that, how many PG's appear every 10 years? To paraphrase Michael Scott - you think PG's grow on trees; well they don't; there is no PG tree.
Absolutely - I think YC's overall "consumer surplus" is over $10b, since it somewhat changed the game for early stage startups in general, not just startups in YC.
