Innumeracy: A term meant to convey a person’s inability to make sense of the numbers that run their lives. Innumeracy was coined by cognitive scientist Douglas R Hofstadter in one of his Metamagical Thema columns for Scientific American in the early nineteen eighties. Later that decade mathematician John Allen Paulos published the book Innumeracy. In it he includes the notion of chance as well to that of numbers.
From “Money Merge Advantage”, (please note, this blog was suspended by WordPress for TOS violations) an MMA agent’s blog:
“In FACT, The software alone could still beat the 2nd scenario (putting the $300 discretionary to the mortgage each month) WITHOUT using that discretionary income AT ALL. Yes, SERIOUSLY!”
If you have no idea what Money Merge Accounts are, or what I am talking about, please see my Money Merge Links page for references and then read on. In the blog I reference, the example starts with $250K, 30 yr, 6.5% mortgage. Then we are told a bi-weekly will provide some $75,800 worth of interest savings. No problem there, a bi-weekly is like paying 8% higher than the required monthly payment, usually in the form of a 13th payment snuck in once a year. The examples then offer that $300 more each month will cut the mortgage down to 19 yrs 8 months, which I still follow. But then the blog writer claims that with no extra money, beyond the $300, MMA will cut the mortgage to 14 yrs 4 months! This is beyond the wildest claims I’ve seen so far, and completely beyond reason.
Lastly, came the quote above, suggesting that with no extra funds available, the HELOC shuffle alone can produce savings greater than a $300 monthly principal payment would achieve. This raises new and troubling questions. The couple in the example have a net income of $3800/mo. If their HELOC were 0%, and they borrowed this $3800 at the beginning of each month, and paid it back at month’s end, it would gain them just under $21 per month, nowhere near $300. And no HELOC offers a 0% interest rate. At best, the HELOC is a percent or two under the fixed rate mortgage. This is simple math, folks, and no “sophisticated algorithms” are going to change the fact that 1+1=2 or that the best one might squeeze out of their HELOC shuffle efforts is $20-$30 per month, certainly not $300.
