I’m not going to do the math, but I think what he is saying that if you were to invest the $xxx money yourself,
It’s pretty close. For an adult lifetime @ 574, you need to yield about 4.6% to pay for that license and earn the following year’s $25 license.
The exercise really depends on future costs as much as investment strategy. I’m guessing you’d need to break 5.5% year to year to cover the increasing license and any fees and taxes related to the investment? Buying a lifetime certainly is not a horrible investment imo. As stated, they make an awesome gift.
I got my lifetime the year they came out as a birthday gift from my wife, then girlfriend.
