Total costs = Fixed costs + Total variable costs Total Cost = Fixed Cost + (Volume * Variable Cost Rate) Total Variable Cost = Volume * Variable Cost Rate Variable Cost Rate (per unit) = Total Variable cost/Volume Average Cost (per unit) = Total cost / Volume Total Revenue = Volume * Price per unit Profit = Total Revenue – Total Cost Profit = (Volume*Price)-Fixed Cost-(Volume*Variable cost Rate) Total Contribution Margin = Total Revenue-Total Variable cost Contribution Margin per unit = Price per unit – Variable cost Rate Breakeven Point in volume is the volume make the profit Equal zero 0 = (volume *Price per unit)-Fixed cost – (volume*Variable cost rate) Simple equation: Breakeven Point in volume = Fixed Cost / Contribution Margin per unit The volume Need To achieve Desired Profit = (Fixed Cost + Desired Profit)/ Contribution Margin per unit Economic break even : (fixed cost + Desired profit)/ Contribution margin per unit Profit and loss Contribution Margin format Total Revenue (volume * price per unit) Less : Total Variable Cost (Volume * Variable cost Rate) = Total Contribution Margin Less : Fixed Cost = Net Profit or Loss Notes : at Breake even point , Total Contribution margin = Fixed cost
