Understanding business value
Most businesses are valued as a multiple of their earnings. Larger companies use EBITDA; smaller, owner-operated businesses use SDE (net profit plus owner pay). The multiple depends on your industry, growth and risk. Try the business valuation calculator or the simpler small business version.
Knowing your numbers
Profit and break-even are the foundation of good decisions. Use the profit calculator to see your margins, and the break-even calculator to set realistic sales targets.
Selling online
Fees and advertising can quietly erode e-commerce profit. The e-commerce profit calculator and the Amazon FBA calculator show your true margin after every cost.
