The answer to this question varies depending on your circumstances. While there are some general, personal questions to ask yourself when assessing which debts are worth it, only you can really determine whether your debt is good or bad.

It depends on how much your life costs — there is no hard-and-fast number that applies to everyone. Your safest bet is to have three to six months’ worth of your total living expenses (rent, food, transportation, monthly bills) tucked away for emergencies. That way, if you suddenly lose your job or fall upon hard times, you can maintain your lifestyle without racking up major debt.

APR is an acronym for “annual percentage rate.” It primarily matters if you plan on not paying off your credit card bill every month. APR is the interest rate you will be charged on any amount you did not pay in full from your last statement balance. If you’re debating between credit cards and plan to carry a balance, comparing APRs is a good way to see which card might be better for you.
