@Barry2021,
Your wife does not seem to understand how credit works. It's possible that she also has no idea how compounding works. I work in business credit, and it relates rather directly to personal.
Calmly (and yes, I do mean that. Getting steamed—no matter how much you want to—and I do understand that—is not going to help anything), explain that taking $ out of a credit card means it's a
loan and interest is charged. It's different from taking it out via an ATM, even if you go outside your bank's network and are charged a fee.
Pull out the statements and the bills and look at them together. Show her (again, calmly) that her (for example) $20 from the card has cost $34 because of interest. Again, calmly, show her the interest rate she's paying. You don't have to go into the weeds. That will not help. Rather, (again an example) show her:
you(maybe) wrote:A charge of $100 garners 15% in interest. At the end of the year, that sounds like just $15, right? But it's actually more, due to compounding. Every month, the credit card issuer charges interest on the balance. This $100 balance is charged 1/12 of $15 (that's because it's for a month), which is $1.25. But then next month, if the $100 balance is carried over, now the credit card issuer charges 1/12 of $16.25 as interest. That's a little over an extra 14 cents. Still doesn't sound bad, right?
This happens for every single dollar in the balance. For a $1,000 balance, that 15% starts off as $12.50. Then in the second month, it's $13.54. That's added together. So for a $1,000 balance kept for just two months, the interest compounds to over $25. For a $5,000 balance kept for just one month, the interest compounds to over $60, which is right around the cost of an evening meal out.
And that's for only a month. Since we're talking about three years and $14,000, the numbers are obviously going to be higher. Every time a credit card company provides a "minimum amount to pay", they're not doing the debtor any favors. Most of the time, if it hits whatever their rock bottom minimum is, this amount doesn't even cover the cost of the compounding interest. All it does is dig a person deeper into the hole.
Please note that I have been careful to not use the word
you in this example.
This is because accusing and yelling won't fix anything.
And why am I suggesting this at all? Because, as you rightfully stated, you're on the hook for this. If she does not learn, then you could be dragged into bankruptcy eventually.
A financial literacy class would be a really good idea right about now.
Credit is not play money. A bad credit rating will dog a person forever if they don't fix it. Bad FICO scores mean not getting loans, or at least not getting good loans with good interest rates and longer payment terms.
Leaving her out there to slowly twist in the wind will do
you no favors.
