The Lehman Scale is a traditional schedule of business broker and advisers’ chargeable fees. The scale is based on the transaction size of the deal, and is normally payable by the vendor(s) of the business once the purchaser's funds have cleared.
5% on the first $1,000,000, plus
4% on the second $1,000,000, plus
3% on the third $1,000,000, plus
