A good rule of thumb is the 50/30/20 budget rule:
50% for needs (rent, food, bills)
30% for wants (entertainment, shopping)
20% for savings and debt repayment
However, if you're aiming for faster financial independence, saving 30–50% of your income (or more) is ideal. Always prioritize an emergency fund (3–6 months of expenses), then invest the rest wisely
