Excluding my mortgage, I’m a debt-free individual. That means my credit card is a pretty lonely lil’ guy. He doesn’t even get to live in my wallet. He’s entombed in my office with my library card, my old student ID, and that Best Buy gift card with only $3.52 left on it. He has a zero-balance and a $10,000 limit.
I used to keep $6,000 in cash squirreled away as part of an emergency fund—enough to make a few rent payments if I lost my job or had to cover an unexpected accident deductible. I was very lucky, and none of those things ever came to pass; but this meant my emergency fund sat in my savings account, slowly depreciating. Meanwhile, I was toying with the idea of closing my credit card altogether—after all, I never used it.
But eventually, I saw a wonderful opportunity to justify that card, and put my emergency fund to better use: I invested the $6K and designated my credit card as my new emergency fund. I’ve come to think that’s the ideal role for credit cards to play in a debt-free person’s life.
