The income approach is one of the most commonly used methods within business valuation. There are 4 main things to consider when using the income approach.
1, Normalization of the P&Ls from the last 3-5 years. The most common normalization is done to the salary of the owner or owners. It is common that business owners work 70h a week, and take out less salary then their market rate as CEOs. Other business owners don´t work at all, but still take a healthy salary, mostly because they can. Both of these, need to be normalized for.
2, The weighting between different fiscal years. Which year or years should be considered as representative and why? Oftentimes, the most reasonable is to spread it out between several fiscal years with different weighting.
3, Choice of multiple.
“One man shows” typically receive a multiple between 1 and 3.
Business that are above “one man shows” but under the size where they get attention from private equity firms, typically receive multiple 3 without assets included. If the assets are included they typically receive a multiple between 3-5.
When you reach the size where you get attention from private equity firms, the multiple is usually in the 4-7 range, but it varies heavily. Companies that are technologically advanced receive much higher multiples.
4, The definition of the multiple.
SDE stands for Seller´s Discretionary Earnings. In plain English, it is profit and owner salary combined.
EBITDA stand for Earnings Before Interest Taxes Depreciation and Amortization. In plain English, it is somewhat similar to a gross profit.
Normalized net profit is the only thing that one really should consider.
