Which method of budgeting is least commonly used due to expense and the difficulty of analyzing specific costs?

Performance budgeting is a method that focuses on the relationship between the funding received and the measurable results achieved through program activities. This approach has gained traction for its emphasis on accountability and outcomes; however, it is also the least commonly used method primarily due to its complexity and the significant resources required for effective implementation. Analyzing specific costs tied to performance outcomes can be challenging, as it often necessitates extensive data collection and evaluation processes.

In contrast to performance budgeting, methods like line item budgeting and incremental budgeting are more straightforward and commonly used because they are easier to understand and implement. Zero-based budgeting, while comprehensive, also requires considerable time and effort to justify all expenses from a "zero base." This can deter its frequent use compared to the simpler alternatives. Overall, the intricacy and resource demands make performance budgeting less prevalent among organizations seeking efficient budget methods.
