Its not the same to win a Percentage over Cost VS Percentage over Margin
This means that if you substract 16% to the Price with taxes, it will NEVER go under your base cost of product/service. Alternatively, if you use the price without taxes, you'll already be adding a percentage margin of winnings and be able to calculate the taxes simply by adding 16%
How it works:
Input base cost:
The base cost is exactly how much you product or service costs. Should be the amount you'll have to pay away. Can be either your cost of operation or third party products/services that you'll need to pay
BASIC:
The margin is the total sum of all taxes + your desired win margin
ADVANCED:
IVA is the main tax over the base cost
IT is the next tax over the transaction
IUE is the anual tax over the yearly winnings
Margin is the desired percentage of winnings over the cost
PRO:
Not yet implemented
Thats it. As soon as you input something, the tax and tax-less prices should already be calculated.
