Business Appraisal Calculator
Estimate the fair market value of your company using SDE and Multiples
Estimated Market Value
Where SDE (Seller’s Discretionary Earnings) = Net Profit + Owner Salary + Add-backs.
| Financial Metric | Amount ($) | % of Revenue |
|---|---|---|
| Annual Revenue | $0 | 100% |
| Net Profit | $0 | 0% |
| Adjustments (Salary + Add-backs) | $0 | 0% |

What is a Business Appraisal Calculator?
A business appraisal calculator is a financial tool designed to estimate the fair market value of a company. Unlike simple asset assessments, a robust business appraisal calculator focuses on the cash flow a business generates, specifically a metric known as Seller’s Discretionary Earnings (SDE). This tool is essential for business owners planning an exit, potential buyers assessing an acquisition, or brokers setting a listing price.
While professional valuations can cost thousands of dollars, a digital business appraisal calculator provides a reliable baseline by applying industry-standard multipliers to your financial data. It bridges the gap between guesswork and a formal certified valuation.
Common misconceptions include thinking that revenue alone dictates value. In reality, a business appraisal calculator prioritizes profitability and transferability over top-line sales figures.
Business Appraisal Calculator Formula and Math
The core logic behind this business appraisal calculator is the SDE Multiple Method. This is the most widely accepted approach for valuing small to medium-sized businesses (SMBs).
The Formula
1. Calculate SDE:
SDE = Net Profit + Owner’s Salary + Depreciation + One-time Expenses
2. Calculate Valuation:
Estimated Value = SDE × Industry Multiple
| Variable | Meaning | Typical Range |
|---|---|---|
| Net Profit | Taxable income reported on the bottom line. | 10% – 30% of Revenue |
| Add-Backs | Owner perks, salary, and non-cash expenses restored to profit. | Varies wildly |
| SDE | Seller’s Discretionary Earnings (True Cash Flow). | Higher is better |
| Multiple | The multiplier applied based on risk and growth. | 2.0x – 4.0x |
Practical Examples
Example 1: The Local Coffee Shop
A coffee shop owner wants to sell. The business appraisal calculator inputs would look like this:
- Revenue: $400,000
- Net Profit: $50,000
- Owner Salary: $60,000 (Owner manages the shop)
- Add-backs: $10,000 (Depreciation of machine)
Calculated SDE: $120,000.
Using a typical retail multiple of 2.2x, the business appraisal calculator estimates the value at $264,000.
Example 2: The Niche E-Commerce Store
An online retailer with high margins uses the business appraisal calculator:
- Revenue: $1,000,000
- Net Profit: $300,000
- Owner Salary: $0 (Owner takes dividends)
- Add-backs: $20,000 (One-time web design fee)
Calculated SDE: $320,000.
Online businesses often command higher multiples. Using a 3.5x multiple, the result is $1,120,000.
How to Use This Business Appraisal Calculator
- Gather Financials: Have your P&L statement or tax returns ready.
- Input Revenue & Profit: Enter the annual gross sales and the net income from your tax return.
- Identify Add-backs: This is critical. Enter the salary you pay yourself, any personal expenses run through the business (like a car), and non-cash charges like depreciation. The business appraisal calculator needs these to determine the true earning power (SDE).
- Select a Multiple: Choose a multiple that reflects your business risk. If your business is stable with recurring revenue, choose 3.0x. If it relies heavily on you personally, choose 2.0x.
- Analyze Results: Use the generated chart to see how sensitive your valuation is to the multiple used.
Key Factors That Affect Business Appraisal Calculator Results
Several variables influence the final output of a business appraisal calculator beyond just the numbers:
- Owner Dependency: If the business falls apart without you, the multiple drops. A business appraisal calculator cannot “see” this risk, so you must adjust the multiple down manually (e.g., to 1.5x or 2.0x).
- Recurring Revenue: Subscription models or long-term contracts reduce risk, increasing the multiple (often 3.0x – 5.0x).
- Growth Trends: A business with declining revenue over 3 years will be valued significantly lower than one with 20% year-over-year growth.
- Customer Concentration: If one client makes up 50% of revenue, the risk is high. A savvy user of a business appraisal calculator adjusts the multiple downward for this risk.
- Market Conditions: Interest rates affect buyer financing. Higher rates typically lower the multiples used in a business appraisal calculator because debt is more expensive for buyers.
- Clean Books: Clear financial records justify higher add-backs. If you cannot prove an add-back, a buyer (and the business appraisal calculator logic) should ignore it.
Frequently Asked Questions (FAQ)
How accurate is this business appraisal calculator?
This business appraisal calculator provides a high-quality estimate based on the SDE method. However, the final sale price depends on negotiation, deal structure, and market timing.
What is a good SDE multiple?
For most Main Street businesses (revenue under $5M), a multiple between 2.0x and 3.0x is standard. Online businesses or those with proprietary tech may see 3.5x to 5.0x.
Should I include inventory in the business appraisal calculator inputs?
Usually, the valuation derived from an SDE multiple is “plus inventory.” This means the inventory value is added on top of the calculated price at closing. This calculator estimates the enterprise goodwill value.
Does this calculator work for startups?
Startups with no profit cannot be valued using SDE. This business appraisal calculator is designed for established businesses with cash flow.
Why is Owner’s Salary added back?
Because the new owner will receive that money. It is part of the total financial benefit of owning the company.
Can I use this for tax purposes?
No. For IRS filing or legal disputes, you need a Certified Business Valuation (CBV) from a licensed professional, not an online business appraisal calculator.
How do I increase my business value?
Focus on increasing SDE (profitability) and reducing owner dependency. This allows you to input higher numbers and select a higher multiple in the business appraisal calculator.
What is the difference between SDE and EBITDA?
SDE adds back one owner’s salary (common for small biz). EBITDA adds back no owner salary (assuming a manager is paid). EBITDA is used for larger companies (>$5M revenue).
