Make a copy of the financial worksheet.

You only need to enter the price and cost of your products. You might also change the initial inventory if you are a service based business with no inventory.

After entering the numbers, you can look at the break even analysis.

This is going to give you the number of items you need to sell in a year to break even. That is at the very bottom.  You can see how adjusting the numbers at the top impacts the breakeven point.
