Zero Based Budgeting

Zero-based budgeting is a financial planning method in which every expense must be justified and approved from scratch at the start of each budgeting period, rather than simply adjusting the previous period's budget. It starts from a zero base, requiring managers to build their budgets by demonstrating the necessity of each cost. This approach can help organisations eliminate inefficiencies and allocate resources more effectively.

A trading firm applying zero-based budgeting to its operations might require each department to justify its expenses at the start of every quarter, ensuring that technology costs, data subscriptions, and staffing are all directly contributing to the firm's performance. For individual traders, adopting a zero-based approach to their trading costs — regularly evaluating whether platform fees, data feeds, and educational subscriptions are delivering genuine value — can improve overall profitability by keeping overhead costs lean and purposeful.
