Your budget seems to be missing some very important categories. Do you spend NOTHING other than the $280 for food in a month? no subscriptions, games, gifts, socks, meals with GF, donations, new garbage can or sunscreen, no haircuts, no scissors or, well, ANYTHING?
Renter's insurance? Other minor medical deductions or co-pays? Parking tickets? Driver License Renewals? Engagement ring savings? You get the idea.
It could be, given that you just graduated,that you don't spend anything else, but it wont stay that way unless you put a budget line for these other items, even a small one, and track that you keep to it.
Next. I highly recommend getting rid of the car loan ASAP. A car loan is sometimes needed, but after your first one, you want to never have a car loan again. Pay it off, within 12-18 months. Pay the SL debt as a minimum payment that keeps you current for now.
Now, set some life / financial goals for yourself. Take the time to think about what you want in the next 10 years. Include savings, but also paint a mental picture of your everyday life. Are you DINK? Living in a rural location? NY? It is important to understand what you want, initially, and then share with your SO before you marry, and then adjust it to a mutal vision (give and take). Otherwise you risk accepting the other person's vision for your life plan, besotted as you may be.
Finally, you are making a lot of money for a single person in AL, don't fall down and start buying a lot of dinners out and fancy clothing or watches, etc. Make a budget (even a loose or generous one), create a few goals, and you won't lifestyle creep by accident. This was the best advice I received when I was a 22 yo new engineering graduate with full time work. In hindsight, it was some of the best advice I have ever received. .... I only wish someone had warned me about the horrors of being trapped in a large car loan at the same time!!...
Good Luck.
