An article costs $13.80 (excluding tax it costs $12.00). What percentage is applied?

Could you give me the formula to calculate the percentage applied on an item if you have both the import including and excluding taxes?

    First you calculate how much was added:

    13.80 - 12.00 = 1.80

    Then you find what percentage of the initial figure that was:

    1.80/12.00*100 = 15%

    Or if you want it as a single formula it's:

    (13.80 - 12.00)/12.00*100
