I'm currently a graduate student and since I want to build credit, I got my first credit card. However, the credit limit is really low (< $1000). I've been reading that I should always keep my utilization rate < 30%. This seems a bit low as that's like $200. For example, what if I want to buy an airline ticket home (costs $400), wouldn't buying using my credit card hurt my credit score?
I have no issues paying off my balance in full and on time, but would a better method be to not worry about the utilization rate too much now since the credit limit is low, and quickly acquire credit limit increases? 400/1000 is 40% utilization, but 400/10000 is just 4% utilization. It'll be probably 10 years before I need a loan to buy something big. Perhaps I'm overthinking this too much?
