A fixed budget is a kind of budget where the income and the expenditure are Pre-determined. Irrespective of any fluctuation or change, this budget is static. Companies that are static, execute the same sort of transactions can significantly benefit from a fixed budget. But wherever there are fluctuations, a fixed budget doesn’t turn out to be the most suited one.
Flexible budget, on the other hand, is a budget that is flexible as per the needs of the hour. For example, if the company sees that it can sell off more of its products by expending more in advertisement costs, a flexible budget would help execute that. That’s why a flexible budget is very effective for companies who go through a lot of changes during a particular period. It is much more complicated than the fixed budget too.
