Too much, especially since I just financed a bunch of house stuff via Synchrony Bank which is classified as a "credit card" even though it's low interest, fixed payment repayment (It wasn't optional house stuff, hooray plumbing nightmares)
$0 accruing interest. Everything gets paid off automatically.
I've only got about $25,000 in debt now, between land and car loans. The former is at 3.9% (great rate), and the latter is at 1.8% (basically cash), so almost everything goes to principle. I'm mostly paying myself now.
I don't carry debt on my credit card. It's just a convenience for larger purchases and game subscriptions, and I pay off the full balance every month. I have no debt in my life at all, actually, with the exception of my mortgage. That will be paid in full in three more years. This will be the second house I owned outright.
Debt is evil. The key to a happy life is living below your means, not beyond them. If you can't pay cash for it, you can't afford it.
Maybe around $200. Buy groceries and gas with it and pay it all off when the bill's due. If you've racked up some debt you're doing it wrong. I've met too many dummies that get credit cards and think "FREE MONEY" now they're fucked...
If you can't buy whatever you're looking to get with that credit card right now, cash. Don't use it.
I pay mine bi-weekly. I just paid again, so I am at $0, but it can grow up to a few thousand.
I wouldn't say CC's are a net negative. Building credit is one of the most important factors taken into account in your credit score, which enables you to access loans that allow you to buy a house or start a business. It is absolutely important to pay your CC debt ASAP, but completely denying the use of them is a bit short-sighted.
