Most common mistake: underestimating depreciation. Your vehicle or equipment loses value every month whether you use it or not. Divide current replacement cost by months you expect to keep it. Include this in standing costs.

RightCost.uk provides pricing guidance based on the data you enter. It is not a substitute for professional financial, accounting, or business advice. Suggested prices are illustrative only. Verify all figures against your actual costs and market before using in a client quote. JMO Transport Ltd accepts no liability for business decisions made based on outputs from this tool.

This tool does not automatically calculate employer National Insurance contributions, PAYE administration, pension auto-enrolment, holiday pay, or statutory sick pay. If you employ staff or use PAYE contractors, these costs must be added manually to your labour or standing cost fields. For self-employed owner-operators paying themselves as a sole trader or director, personal tax and National Insurance are also not included. Always verify your full cost base with a qualified accountant before using results in a formal quote or pricing decision.
