Set up a monthly budget

Help me set up a monthly budget. My income is [RENDA] and my main expenses are: [GASTOS]. Organize by categories, suggest a healthy distribution (e.g., the 50-30-20 rule), point out where I might be spending too much and how to balance. Goal: have control and have money left over at the end of the month. (I'm not a financial consultant, consider this only as organization.)
