The overall message is spot on. Annual fees make up 75-80% of the contract cost. I calculated a little differently, Assuming an annual maintenance increase of 5% each year for OKW and 3.5% each year for BWV now through 2042. The annual increase will change some but going off the last 15 years that’s the average.
150 BWV $101.63 would be almost $4500 cheaper vs
150 OKW $67.00 over the rest of the contract life if starting with 2026 dues.
This is why it’s important to look at the total cost over the lifetime. We love BWV but I wanted to pay cash so OKW won out on this one.
