Activity Based Costing vs Traditional Costing: Key Differences and Impact on Profit
Activity Based Costing (ABC) assigns overhead to products by tracing activities they actually use; Traditional Costing spreads overhead using a single, broad rate like direct-labor hours.
Executives mix them up because both aim to price products profitably, yet ABC feels like extra bookkeeping while Traditional seems faster. The confusion hits when hidden losers look like winners under the old method.
Key Differences
ABC tracks multiple cost drivers (set-ups, inspections); Traditional relies on one volume base. ABC highlights true product profitability; Traditional may distort it by averaging.
Which One Should You Choose?
Choose ABC when overhead is high and products differ widely; stick with Traditional if operations are simple and overhead is small relative to direct costs.
Examples and Daily Life
Imagine a bakery: ABC counts each custom cake’s design time; Traditional lumps all oven costs equally. One shows which cake earns profit, the other hides it.
Can small firms use ABC?
Yes, they can scale it down to a few key activities without complex software.
Does Traditional always mislead?
Not always; when overhead is low and products are similar, the distortion is minimal.
