Valuation

How Window Cleaning Businesses Are Valued

A clear explanation of how multiples work and what drives your number.

The SDE Method

Most Window Cleaning businesses under $5M in revenue are valued using Seller's Discretionary Earnings (SDE). SDE represents the total financial benefit to a single working owner - essentially, net profit plus owner salary, personal expenses run through the business, depreciation, and one-time costs.

Once SDE is calculated, it's multiplied by an industry-specific multiple (typically 2.0x to 3.5x for Window Cleaning) to arrive at an estimated business value.

What About EBITDA?

EBITDA is typically used for larger businesses ($5M+ revenue) with absentee ownership. Unlike SDE, it does not add back the owner's salary.

Example Valuation

Annual Revenue$400,000
Net Profit (tax return)$60,000
+ Owner Salary$50,000
+ Personal Expenses$12,000
+ Depreciation$10,000
= Adjusted SDE$132,000
Estimated Value Range
