Breakeven
Let's build a breakeven (no earnings nor losses) of a specific business.
e.g. We want to calculate how many units of each product we need to sell in order to the final result be equal to zero If you sell more products, your business will produce profits, but if you sell less your business will produce losses.
 
 
In this case, we obtain a profit of $340.00
Now, we want to obtain no losses nor profits (breakeven)
How much, should we increment the price of each product?
Breakeven is the perfect tool for this type of job.
