Welcome!
If you want to save more money, the formula is simple (but not necessarily easy to do):
1. Maximize income
2. Minimize expenses
3. Invest the difference
If you want to maximize income, look through threads on how to ask for a raise, job hop to increase income, develop a side hustle...there are lots of ways that forum members have come up with to increase their income.
If you want to minimize expenses, then look at the threads that all about refinancing mortgages to get a lower interest rate, Order with which to pay off student loans/credit cards and other debt, and ways to lower other bills and expenses. If you want advice specific to your case, consider posting a full case study (there is a sticky at the top of the Case Study thread that shows you how to post a proper case study with enough info for people to comment on). If you post a case study, be prepared for face punches and to have practically every expense questioned. I’ve found that pretty much nothing is off limits, so you definitely need to approach all comments with an open mind. You’ll get comments on how to save a dollar here or there, but you will also get advice on how to redesign your life so that you simply live on less or need less to be happy.
If you want to invest the difference, then investment order is a good place to start. You can then also post a case study focusing specifically on taxation/401k/IRA/etc issues. As a general rule of thumb, a 50% savings rate is pretty normal here. Some of the really dedicated folk can get their savings rate up to 80%.
Right now, you’re set to save 13%. That’s quite low. Given that your income is not too bad, then it sounds like you have too much going out each month, but we have no idea whether it’s because you have too much house, too much car, too many student loans, or a combo of different things. A case study will give us a chance to help you sort it out.
