I doubt realized returns are available, but I think it's possible to at least very roughly estimate money invested. Their current "deal" is $120k for 7%, and that number has been going up over the years. So say all 1,588 startups they've funded got that investment (not true, since earlier investments were something like $20k). You're looking at about $150m in cash investments. According to
https://www.ycombinator.com/people/, there are about 50 people working full-time at YC. We're being conservative, so let's say 150 people at $150k/year salaries, over the 13 years since YC's founding (again, very high estimates since they obviously did not start with even remotely close to that many people). That's about $300m.
So we're at maybe $450m spent on initial investments and people over the years. Maybe throw in another $200m for extra investments (I presume they re-invest in a couple promising companies on demo day) and other costs.
They say their portfolio's valuation is roughly $80b. Their "deal" is for 7%. I'm not super familiar with the technical stuff but they really only need to keep about 1% of that total value to be fairly successful, and I imagine that number is probably much higher unless I'm misunderstanding some of the details about how fundraising works.
