What is a budget surplus? Let’s say that you normally spend $400 per month on groceries. This month you budget for $10,000,500 and you spend $500 on groceries. You are out $100 more than usual on groceries. You’ll have to make up for it some where else in your budget. But you have a $10,000,000 grocery budget surplus. You should celebrate. Sound good? Perhaps you should go into government.
