I never spend more than 50% of my salary. I give 10% of my salary to the church, and I eat everyday by cooking myself (I mean, I still live with my mom, hahaha). I never buy food outside, I just buy a small snack just on weekends. I was deliberately not spend money to hang out or eat in restaurants, I also do not have a boyfriend. I was determined to save and invest for my future. I'm determined to buy a house and make my family happy, that's when I'll start thinking about hanging out and having fun. Or get a girldfriend.
Nice one! The fact that you are even a lady and working well for yourself to build a future is a pretty good thing. Your guy would definitely be a lucky man if you end up finding one. 50% is good and trust me, with the fact that you do not have much responsibility; you can try to do more.
Yeah, it is important to have a mindset of a certain percentage you want to save as that would always help. Nevertheless, it is always good not to be reasonable as well, it is important to understand that some things can always come up so, it is good to always plan for them.
But it all depends on you and how much you really hope to want to save up for the future, but at least that is a good start.
Budget is good and when writing down the list, savings and miscellaneous among other things is very important.
