The four methods
Discounted cash flow projects future earnings and discounts them at your chosen discount rate - the higher the rate, the lower the value. The multiples method applies a market multiple, such as 4 times EBITDA, to current earnings. Asset-based adds up net assets. The rule of thumb applies an industry shortcut, often a percentage of revenue or a multiple of seller's discretionary earnings. Each reads different evidence, so the four disagree.
