To calculate EBITDA, take the net income from your company's financial statements for the last three years. As the acronym suggests, add back interest, taxes, depreciation and amortization from net income to calculate the company's EBITDA. Once you have completed your analysis, consider asking a business broker or investment banker out for lunch. Present your analysis to them and get their insight on your valuation range, other public companies that might be more comparable or recent transactions in your industry. When you're negotiating the terms of the sale of a business, a Sale of Business Asset Worksheet can help you outline all of the important details. It helps you understand the possible terms that might then be included in a formal legal document—the Business Purchase Agreement—that comes next. A Sale of Business Assets Worksheet helps determine the value of the assets, and what specifically will be considered assets. Any or all of the assets can be selected for purchase. As with all of the Microsoft Excel templates included on this page, the columns can be customized for your business, and calculations are completed for you. In an Asset Purchase Agreement, both buyer and seller agree to the specific terms. Other names for this document: Asset Sale and Purchase Agreement.
