Top-down budgeting focuses on overall corporate growth and objectives. It lets company management decide on the allocation of resources across departments to further the company's growth. With this model, they can begin by allocating to the most critical departments and can better ensure that all departments are more aligned with the company's top-level goal.Top-down budgeting saves time for individual departments as they need not start from scratch. With the overall allocated figure, they can use the previous year’s budget to further allocate the figure across areas. It also reduces complications that would arise in case individual department budgets were to be put together and totaled to make a company-wide budget.
