Using the 50/30/20 rule to get financially stable

Hi, I’m just asking people to look at my budget and let me know what they think. I’m currently having some trouble budgeting and I’ve decided to go with the 50/30/20 rule. This is how my budget works out now. 50% goes to fixed costs such as rent, car insurance, utilities, internet, cell phone bill. Then I have 30% for discretionary spending and 20% for saving. Now I know I just knocked out half of my income with my fixed costs, but I’m hoping it’s a good idea. <br><br>Thanks to anyone that gives me advice. <br><br>Edit: I probably should’ve mentioned I’m 24 right now.
