There are several types of budgets that can be used by organizations depending on their time horizon and nature. Long term budgets span 5-10 years and are used by senior management for research and development or long term financing. Short term budgets cover 1-2 years and are used by industries like textiles. Current budgets focus on months and weeks and cover current activities. Budgets can also be categorized by their functions such as production, sales, expenses, cash flow, capital expenditures, and more. Master budgets integrate the various functional budgets into a single summary budget that is used to coordinate departments. Budgets can also differ in their flexibility, with fixed budgets being less adaptable to changes compared to flexible budgets.
