I know everyone has their own way of doing the math – and deciding what is beneficial for them. Here is one dirt-simple view I used recently.
Although the minimum AddOn for points is 25 points (50 at some resorts) it was actually pretty close to what I’d allow since Grand Floridian in October was 20-24 points per night. I wanted to show it more simply using ONE night instead of a full trip … This is also Direct Pricing vs Resale.
Assumption: One night, Grand Floridian Studio, Lake or Lagoon view, in mid-October = 20-24 points
//
BUY DIRECT those points from DVC (prior to closing costs!) = 22pts x $265 per point = $5,830
Divide Upfront Price by 38 years (roughly 2064-2025) = $153 per year
Plus ANNUAL DUES 22x $8 (prior to annual increases) = $176 per year
DVD Total RANDOM-ROUGH Grand FL DVC Per Night = $ 329
//
Versus NOT buying DVC assumption IF 4% return on funds is allocated…
$5,830 x 4% earned interest = $233 per year (not spending it, nor compounding it)
Plus Annual Dues NOT spent = $176 per year
NON-PURCHASE RANDOM-ROUGH Allowance Towards Future Per Night Trips = $ 409
-----------------
Yes, $329 per night for Grand Floridian with a cool view would seem Very nice, and maybe $409 towards a room (if you did NOT buy and invested your funds instead) might not get you the coolest resort BUT there are downsides avoided if upfront cost or needing flexibility are part of your equation. Honestly, I can find a nice resort in LOTS of places for $409 per night.
My math has holes you can drive a monorail thru, but they gave just enough push to have me put off a DVC Add-On for now. I might look at it again next year – the month prior to my Use Year since that’s when they give a little more banked points advantage lol.
YMMV.
