How to Calculate The Original Number of an Decreased Percentage

  • Calculate the original number of a decreased percentage by dividing the result of decrease by the decimal number from subtracting 100 by the percent number divided by 100.

    Formula:
    X percent decrease of Z is Y
    Z = Y ÷ [( 100 - X ) ÷ 100 ]

    Example:
    5 percent decrease of Z is 50
    Z = 50 ÷ [( 100 - 5 ) ÷ 100 ] = 52.63
