Inflation is just 2% - it assumes you’ll do nothing with your money in the future but that future money is worth less than current money due to inflation. I did not adjust for price changes as we have no idea what they will be. Cash rates have increased sharply but the % discounts for deluxe villas have slowly crept from 20 to 35 percent over the last several years.
DVC price inflation has slowed. It’s very possible a recession will stop it completely while inflation in general increases. So I don’t find it worth guessing at.
The TVM/opportunity cost is 6.5%. That’s they typical return in the S&P after factoring back inflation. The premise is that if you put $25000 in an index fund now and paid for your trips out of that instead of using it to buy DVC, you’d be able to make a lot of trips before you run out of cash. If the % number is positive in the chart though, you are still coming out ahead with DVC (again, before accounting for room discounts)
does that make any sense? I’m not good at explaining this stuff.
