Calculating Break-Even Price or Sales Volume, or how will I know when the price is too low?

Every farmer has faced a scenario where they wonder if it’s worth planting or harvesting a crop. Knowing the price you need to receive or the volume you need to sell at a given price (or some combination of the two) can be helpful in determining whether or not an enterprise is likely to be profitable. A cost/volume/price analysis is the method that you can use to do this calculation.
