Deferred consideration

Vendor loan notes in an MBO: how much a seller can defer

Updated

The seller lending part of the price back is often what makes an MBO add up.

Talk to a specialist The price, the EBITDA and how much the team and the seller put in.

Default: the £5m deal in Clifton Private Finance's worked MBO example, where £500,000 of management equity is 10% of the deal.

Senior lenders size their loan on this figure. YFM Equity Partners asks for at least £1m of profits for an MBO.

Spark Finance: senior debt is typically provided at 3 to 4 times EBITDA. Use your lender's figure.

Harper James: on an MBO as much as 50% of the price may be deferred and paid over 3 to 4 years. Clifton's example defers £1m of £5m, 20%.

Spark Finance: typically 10 to 30% of the purchase price. Clifton's example is 10%.

How this calculator works
  • Senior debt. Spark Finance: the management team contributes equity, typically 10 to 30% of the purchase price, and senior debt is typically provided at 3 to 4 times EBITDA by specialist acquisition lenders. The calculator takes the smaller of your multiple x EBITDA and what the price still needs. (Spark Finance: how to fund a management buyout in the UK)
  • Vendor deferral. Harper James: on an MBO as much as 50% of the purchase price may be deferred and paid out over 3 to 4 years. The calculator treats your percentage as deferred consideration owed to the seller. (Harper James: vendor deferred loans)
  • Stamp Duty. A share purchase pays Stamp Duty at 0.5% on a transfer over £1,000, rounded up to the nearest £5, paid within 30 days of the stock transfer form being signed and dated (GOV.UK, tax when you buy shares, and Stamp Duty on shares). An asset purchase pays no Stamp Duty on shares; any property in it is a separate SDLT question the calculator does not answer. (GOV.UK: Stamp Duty on shares)
  • No lender's terms. The calculator shows the shape of the funding stack, not an offer: a lender sets its own multiple, security, rate, term and covenants. No interest, fees or deal costs are added.
  • The seller's side. If the seller qualifies for Business Asset Disposal Relief, GOV.UK charges 18% on qualifying gains disposed of from 6 April 2026; a buyback by the company itself has its own conditions under CTA 2010, set out on this site. (GOV.UK: Business Asset Disposal Relief, eligibility)
