Calculation guide — Brazil
How do I add tax?
Let r be the percentage divided by 100. For a rate on net price: tax = net × r and gross = net + tax. For a rate on gross price: gross = net ÷ (1 − r), then tax = gross − net.
How do I remove tax?
For a rate on net price: net = gross ÷ (1 + r), then tax = gross − net. For a rate on gross price: tax = gross × r and net = gross − tax. Currency rounding can affect the final minor unit.
