I just stumbled across this handy breakeven calculator (expired link) from Case Western Reserve University. It’s a handy way to analyze the price point at which your business will breakeven, given the costs of production and the volume of sales for your product. First-year economics students and MBAs spend hours pouring over breakeven charts, but this calculator does everything for you. Note that it’s better suited to products than services. If you want to price your services, try using my article on consulting fees.
