How It Works

This estimator uses the SDE Multiple Method, the most common approach for valuing small businesses with under $5M in annual revenue. Here is the methodology:

1. Base Multiple (Industry)

Each industry has a typical SDE multiple range based on historical transaction data. For example, service businesses commonly sell for 2.5x to 3.5x SDE. This tool uses the midpoint of your sector range as the base.

2. Longevity Adjustment

Businesses operating for more than 5 years receive a small multiple increase (up to +0.25x) because longevity signals stability and lowers buyer risk. Businesses under 2 years receive a slight reduction (-0.15x).

3. Growth Adjustment

Strong year-over-year revenue growth (above 15%) adds up to +0.3x to the multiple, reflecting future earnings potential. Declining revenue subtracts from the multiple (down to -0.3x).

4. Valuation Range

The tool outputs three figures: a conservative estimate (base multiple minus 0.4x), a midpoint (adjusted multiple), and an optimistic estimate (base multiple plus 0.4x). The formula is:

Valuation = SDE x Adjusted Multiple
5. Revenue Cross-Check

A secondary sanity check uses a revenue multiple (typically 0.4x to 0.8x annual revenue for most small businesses). If the SDE-based estimate is significantly higher than the revenue-based estimate, a caution note is shown.
