The 50/30/20 rule splits take-home pay into 50% for needs, 30% for wants and 20% for savings and debt repayment. On SAR 10,000 a month that is 5,000, 3,000 and 2,000. Enter a savings target to see the income the rule implies.
Needs, wants and savings
Needs are what you cannot skip: rent, bills, basic food, transport and minimum loan payments. Wants can wait: eating out, travel, subscriptions. Savings cover an emergency fund, investing and paying debt faster.
Treat the rule as a starting point. If rent alone takes 40% of your pay, a temporary 60/20/20 is fine; if costs are low, save more. Always work from take-home pay, and start with an emergency fund of 3 to 6 months of needs.
