What is the formula of marginal costing?

sale-variable cost=(contribution)-fixed cost =(profit):this is the statement of

marginal cost.

(profit volume ratio)p/v ratio=contribution÷sales x 100

mos(margin of safety)=actual sales-break even point(BEP)sales.

mos(margin of safety)units=actual sales(units)-break even point(BEP)sales.(units)

BEP(rs)=fixed cost ÷ pv ratio

BEP(units)=fixed cost ÷ contribution per units

required sales(rs)=fixed cost+desired profit ÷ pv ratio

required sales(units)=fixed cost+desired profit ÷ contribution per unit .

( there is different formula for..when 2yr profit & sales are given)
