How it's calculated

One-off setup costs are paid upfront before you start trading — equipment, premises deposits, professional fees, initial marketing.

Working capital = monthly running costs × number of months. This covers the gap between starting and becoming consistently profitable.

Break-even revenue = monthly costs / assumed gross margin. The monthly turnover needed to cover all your running costs.

Frequently asked questions

How much working capital do I need?

At least three months of running costs, ideally six. Covers the gap before profitability.

Sole trader or limited company?

Sole trader is simpler. Limited company offers liability separation and tax efficiency above ~£30,000 profit.

Can I get a startup loan?

Yes. The government-backed Start Up Loans scheme offers up to £25,000 at 6% with free mentoring.
