FAQs

What is the difference between a cost centre and a profit centre?

A cost centre is responsible for incurring costs without generating revenue, while a profit centre generates revenue and incurs costs. Profit centres are expected to cover costs and make a profit, with managers accountable for overall financial performance.

Why do businesses use budgets?

Businesses use budgets for planning and monitoring, control, coordination and communication, and motivation and efficiency. Regular monitoring helps managers manage functional areas and support objective setting and review.

How do historical figure budgeting and zero-based budgeting differ?

Historical figure budgets rely on prior sales and costs data and are influenced by external factors. Zero-based budgeting allocates no budget initially, so all spending must be justified, making it more time-consuming and evidence-based.
