Each calculator applies fixed, published formulas to the figures you enter. Valuation tools start from maintainable adjusted EBITDA and apply sector multiple ranges from our UK SME Valuation Multiples Guide, then adjust for cash and debt to reach equity value. Scores such as owner dependency and exit readiness weight your answers to the areas buyers test most. Each calculator page shows its formula and a worked example.
This calculator provides general, indicative guidance based solely on the information entered. It is not a formal business valuation, tax calculation, legal opinion or recommendation to accept or reject an offer. Actual value and sale proceeds depend on detailed financial, commercial and transaction-specific factors.
Contact details are requested only if you choose to receive a summary report or ask for a confidential review. Need a formal figure rather than an estimate? See our SME business valuation service and our published valuation methodology.
