A budget is a plan for how you will spend your money over a specific period (daily, weekly, monthly, yearly). It helps you track your income and expenses.
Budget planning is as simple as that:
Start a budget by gathering your bills and pay stubs: think about how you spend money, besides paying your bills. For example, do you buy a cup of coffee every day? Do you pay for education, entertainment? After a month, that coffee, education and entertainment money could add up to an expense you might write down.
When you have your bills and pay stubs: write down your expenses (the money you spend).
Write down how much money you make: in other words: what is your income
Subtract your expenses from how much money you make
If the money you earn is less than your expenses, reduce your expenses by eliminating those that are not necessary or essential.
