Just stumbled across BizEquity.com which with just a few parameters of information can help you valuate a business. Not entirely clear how the valuation works, but from the inputs that it asked me for when trying it out, it looks like the CAPM using a number of different variables to come up with the most accurate discount rate.
There’s even an Accuracy gauge that shows you how accurate the system feels that the valuation is. The more info you provide, the more confident BizEquity is in the valuation. Obviously wouldn’t rely on these number for any actual sale or purchase, but it is a fun tool and could help narrow in on a valuation range.
