Not only do you support local farmers and helping your customers live a healthy lifestyle; it makes business sense too! Here is a handy table that helps you calculate how long it takes you to earn back your investment or your monthly instalment. For example, it is nice to know that your machine pays for itself, should you have chosen to opt for the rent-to-own agreement. If your monthly gross profit exceed  your monthly instalment, you know the machine is paying for itself and you will own the machine after your instalment period.
