P&L based on a Table

PnL Value =

VAR SelectedAttribute = SELECTEDVALUE('PnL Structure'[Attribute])

VAR NetSales = 

    CALCULATE(

        SUM('Unpivoted Table'[Value]),

        'Unpivoted Table'[Attribute] = "Net Sales"

    )

VAR VarContribution = 

    CALCULATE(

        SUM('Unpivoted Table'[Value]),

        'Unpivoted Table'[Attribute] = "Variable Contribution"

    )

VAR GrossProfit = 

    CALCULATE(

        SUM('Unpivoted Table'[Value]),

        'Unpivoted Table'[Attribute] = "Gross Profit"

    )

RETURN

    SWITCH(

        TRUE(),

        SelectedAttribute = "VM %", DIVIDE(VarContribution, NetSales),

        SelectedAttribute = "GM %", DIVIDE(GrossProfit, NetSales),

        CALCULATE(

            SUM('Unpivoted Table'[Value]),

            'Unpivoted Table'[Attribute] = SelectedAttribute

        )

    )

PnL Value (Formatted) =

VAR BaseValue = [PnL Value]

VAR SelectedAttribute = SELECTEDVALUE('PnL Structure'[Attribute])

RETURN

    SWITCH(

        TRUE(),

        SelectedAttribute IN {"VM %", "GM %"}, FORMAT(BaseValue, "0.00%"),

        FORMAT(BaseValue, "#,##0")

    )

Then add a matrix viual.For rows,add PnL Structure[Attribute], for Column add Month or Year upon requirement and for values add PnL Values(formatted) measure.
