Analiza różnicowa

Differential analysis helps managers choose between alternatives by focusing only on costs and revenues that change.
At UrbanFit Gym, Rachel notices that membership growth has slowed.
To increase revenue, she considers introducing weekend fitness workshops for non-members.
She needs to choose between continuing normal operations and adding workshops.
If she launches the workshops, the gym will earn additional registration fees but also incur trainer wages, advertising, and maintenance costs.
Rachel understands that only costs and revenues that differ between the two options are relevant. The gym’s monthly rent, full-time staff salaries, and other fixed costs will remain the same whether she adds the workshops or not, so she excludes them as irrelevant.
Next, she considers opportunity cost. If trainers conduct workshops, they cannot offer private sessions, leading to a decrease in revenue.
Rachel compares the additional revenue with the additional costs and lost benefits.
If the net benefit is positive, she adds the workshops; otherwise, she maintains normal operations.
By focusing only on financial differences, differential analysis supports sound managerial decisions.
