Should I have a higher credit limit on my credit card?
As long as you're not trying to get a higher limit in order to actually spend more money, or might be tempted to do so, it's generally advantageous to have a higher limit if available. A large part of credit score is based on utilization rate (balance due at statement closing divided by credit limit). Basically, you want more than 0% and less than 30% or preferably less than 10% used. Doubling your credit limit halves your utilization rate. And it can be comforting to have it there "in case you need it" in some sort of emergency scenario. Caveats: There's no "right" or "default" amount of credit that you "should have" at any given point in your life. If you're using credit responsibly, and don't need more credit, there's no particular reason to ask for more credit. If you work at it and are patient, it's easy to eventually have tens of thousands of dollars of unused credit limits, but that doesn't really get you anywhere you need to be by itself.
