A budget is said to be balanced when total revenues are equal to, or greater than total expenditures; i.e when there's no budget deficit. Budget deficit, by contrast, is the result of expenses toppling revenues. Revenue is the income a business, company, or government generates from its normal or tax activities, also referred to as a turnover; while expenditures is cost incurred or required for something, say a project. When the budget has nothing to offset, or when there's a budget surplus i.e when revenues exceed expenses, then the budget is said to be balanced.
