Here's the math I used to figure out the value. I'm sure someone better at math has a better formula, but this is what I was using.
Aulani expires in 2062, so has 39 years of points left.
200 points per year x 39 years = 7,800 total points over the remaining life of the contract
An Aulani contract selling at $115 per point (a good, but not impossible deal) would be a $23,000 buy in. Divided by the amount of points left (7,800) means that each point cost $2.95. Add the 2022 maintenance dues of $8.67 per point, and the real cost per point would be $11.62.
A subsidized account selling at $155 per point (way overpriced, IMO) would be $31,000 buy in. Divided by the amount of points left would have each point costing $3.97. Add the 2022 subsidized maintenance dues of $6.52 and the real cost per point is $10.49.
Even at this inflated buy in cost, it is cheaper over the length of the contract. I personally think that price is too high.
The other contracts I saw were $129, which, IMO, is a great deal (I am sale pending on one that was $135). $129 x 200 = $28,800/ 7,800= $3.31 + $6.52 = $9.83.
To compare it to a new direct account, $207 x 200= $41,400/7,800= $5.31 + $8.67 (regular dues) = $13.98. (Which is why the rental companies paying $15.50 are not paying nearly enough.)
