Frequently asked questions

Is tax applied before or after the discount?
The calculator subtracts the discount first, then applies the optional tax rate to the discounted price.
Can the discount exceed 100%?
No. The calculation clamps the discount between 0% and 100%, so the discounted price cannot become negative.
Which currency does the result use?
The interface displays dollar amounts. The percentage arithmetic is currency-independent, but no alternative currency symbol can be selected.
