Here is the deal with this calculator. I used a calculator builder called JSCalc.io. It allowed me to put this together in a relatively short time, which is awesome. It is free up to 500 impressions(page loads) per month, after that it is $9-10 a month. I am not making money off of this caculator, nor do I want to. So I plan to stick with the free version. I just built it, so I am not sure how it will work when the max is reached. I am providing a link to a copy of a google sheet with the same calculator that you can use all you want.
