The Simple Math Behind a 3x Venture Fund: Why Your Best Investment Needs to Return the Whole Thing

According to SaaStr's Jason Lemkin, venture capital mathematics boils down to one brutal truth: you need your best investment to return your entire fund. The benchmark is a three-times net return—the minimum needed to raise a follow-on fund. Only the top ten percent of venture funds achieve it; roughly ninety-five percent don't return enough to justify the risk and illiquidity that investors accept. Here's the formula Lemkin outlines: put ten percent of your fund into your single best investment, and that company must return thirty times your total capital across multiple rounds. In practice, that's a hundred-times multiplier on your entry price, accounting for follow-ons and dilution. Let the rest return one times, and you've hit four times gross, or three times net. This explains classic VC behavior: the obsession with pro-rata rights, the doubling down on clear winners, the apparent abandonment of five-times returns. You need one outlier to return your entire fund. Find two such companies, and you're in a top-five-percent fund.
