I am a wirehouse veteran who has worked at the same firm for 20 years and has never moved. I like my office and I like my manager and I am reasonably happy with my firm, but I sometimes wonder if I'm missing the boat by not taking a check to go elsewhere. But the math doesn't make sense to me. Let's say I gross 500k (it's really more like 550k, but let's keep the math easy) and my payout is 40%. So my net is $200,000 a year. Let's say another wirehouse offers me an upfront check equaling 100% of my gross to sign a nine-year deal. At first glance that $500,000 looks pretty tempting. However, I've always heard that, on average, 80% of your book moves with you. So if I go through all the hassle of moving, I'll be grossing $400,000 a year and netting $160,000 (actually probably even less, because the payout would be less on 400k). My plan is to work another 20 years, so that means I'm sacrificing more than $800,000 of future pay to get an upfront check for $500,000. Of course, I could invest the $500,000 and grow it over the years, but by the same token the $100,000 in assets I leave behind would have grown over the years, giving me more and more gross down the road. So my question is, given that I'm happy where I am, what kind of an offer would make moving worth my while? Or am I missing something, and the offers of 80% and 100% of my gross somehow make sense?
