Contribution margin ratio is overall total contribution margin while contribution margin ration per unit is the allocation of total production contribution margin to per unit basis.
Formula for calculating average Contribution margin Average contribution margin = total contribution margin / total number of units
Contribution margin for per machine hour is as follows:total contribution margin / number of machine hours = contribution margin per hour
Contribution margin per unit = Contribution margin / number of units of products Contribution margin ratio = Contribution margin / Net sales The formula is different for both situations because contribution margin per unit calculates the contribution margin for one unit of product while contribution margin ratio calculates the contribution margin for total overall sales as overall sales may be included different mix of products with diff rent fixed and variable costs that's why both of these are calculated separately
Formula for contribution is as follows: Sales revenue xxxx Less: Variable cost xxxx Contribution margin xxxx
