Frequently asked questions
What markup should I use?
It depends on your industry, costs and competition. Work back from the margin you need to cover overheads and profit.
Results are estimates for planning, not financial, tax or investment advice. Rates and rules change — confirm with your bank, the scheme's official notice or a CA. Last reviewed 13 October 2026.
