So for the past 4-5 years, I was maxed out at my pay grade and therefore not eligible for an annual performance raise (called a "Quality Step Increase" in govspeak), so instead, I was given an extra week of vacation as a performance award. Because I am in the senior earning category for vacation time, the additional week resulted in just over 6 weeks of vacation time annually for those years. Man, I got pretty used to that, as I LOVE to take vacations! But last year, the pay grade for my position was fortuitously elevated to the next higher grade, so this year, assuming I'm in line for a performance award (which I fully expect), I am now eligible for a Quality Step Increase, which amounts to precisely $4,284/year. I found myself thinking about it, and because I have several vacations planned this year, I was pretty sure I was going to forego the raise and take the usual extra week of vacation instead, figuring that the raise would only be about $3k after deductions.
But then I put on my economics/MMM hat and started crunching the numbers. First off, the pay raise would increase my High-3 for purposes of calculating my pension benefit. Not by a lot, but by enough to matter -- $132/mo., or $1,584 annually. In turn, this would lessen the withdrawal burden on my 401k in retirement by the same amount, which effectively means that I could leave $1,584/yr invested and earning let's say 6%. Over a 30-year retirement period, that amounts to $132,742. In addition, the $3k or so raise for the next 3 years (until retirement), invested at 6%, and allowed to grow an additional 30 years, would be $58,124. So the total, by my math, is $190,866 foregone if I choose the one extra week of vacation over the pay raise.
Does this sound right? Assuming it is, it's a pretty obvious choice, isn't it? It's not like I'm working an extra year, I'm simply taking 5 weeks of vacation this year instead of 6. Would anybody choose the vacation over the raise? (to be clear, I don't "need" the extra money, as my numbers are solid whether I take this raise or not, but it certainly adds a nice buffer at a pretty insignificant cost, IMHO).
