This thread is a couple of years old, but is probably a good place to pin the video I’m pasting below…
I’ve wondered how much money I might save by purchasing several APs now under the assumption that Disney will keep raising prices every year. So, I created a spreadsheet! (Go figure.)
My sheet lets you enter the number of APs to buy, the estimated annual price increases, along with your savings interest rate to determine how much interest you would lose by using the money now to fund your crippling Disney habit.
You can then tell the sheet to start using APs at some year in the future - a summary table at top will tell you how much you’d save (or lose maybe) with a fistful of APs.
Caveat: My sheet assumes you buy a new AP every year and doesn’t factor in renewal costs, because that would get ugly fast on the spreadsheet front. This is just a fun mind problem, after all.
Also, I assume anyone doing this would be using cash on hand rather than any funds earmarked for long term investing that might earn a much higher rate of interest.
You can play around with the sheet here.
Plus - if you act now (or later even), you can watch my rambling 10 minute video on how to use the sheet! At no cost. (Except for slowly decaying brain cells, maybe.)
Here be the video…
