My wife and I are on the other end of the spectrum. We have no credit card debt and haven't for 20 years or more. We do have two credit cards that we pay in full each month that we use as charge cards not credit cards:
Chase Freedom Visa with 1% back on everything and 3% back on gas, groceries and fast food (I don't understand the fast food thing but whatever). When you accumulate $200 worth of rebate they send you a check for $250 (extra $50 bonus for waiting till $200 to withdraw instead of $50 increments).
Discover Card with 5% back on the first $100 of gas each month. Gas and Sam's Club are the only thing we use this card for.
After you get your debt payed off it's even a better feeling to have the credit card companies pay you. Their rebates earn us over $1000 each year and we pay them zero interest and no fees. It doesn't get much better than that.
Assuming you do the above and have no other "revolving" debt (monthly payments) other than an affordable mortgage payment your credit score (FICO) will be over 800.
You guys are right, it's time for us to start driving the bus instead of the financial institutions that have proved their incompetence.
I approve your spending discipline. Mostly because I am a tight ***, my wife and I also have taken this same path. In addition, I have never bought a car on finance. I have had to take out a 6-month note a few times to float a particular car purchase, but nothing longer.
Simply put, if I don't have the bucks to buy something, I don't buy it. I understand all too well how compound interest works, and, if I forget, my wife the mathematician is there to remind me. Of course, house mortgages are another matter, but I have strived to pay them down and off as quickly as possible, too.
I hope this doesn't sound sanctimonious, and I do understand how unplanned expenses have an ugly way of shouldering into our lives. I've been blessed never to have gone through a divorce, have had a stable job all of my career (as has my wife), have endured no catastrophic illnesses, so my plan was never put to a serious strain, but I paid my own way through four years of college plus three years of post-graduate study (never went hungry, but was a bit leaner than now), and built from there.
We do have two or three credit cards, but in the last 25 years never failed to pay off the entire balance each month, and never carried a balance beyond two months.
I view live in the same perspective as the game Monopoly. Avoid debt as far as you can, invest as much and early as is reasonably possible, and you will hang onto much more of what you earn in the long run.
