What Is Cost Per Wear? Formula, Examples and Calculator
Cost per wear divides the net cost of an item by the number of times it has been worn. It is useful for understanding use, not for reducing every clothing decision to a single number.
The Basic Cost-Per-Wear Formula
At its simplest, Cost Per Wear (CPW) is calculated by dividing the purchase price of a garment by the total number of times you actually wear it. However, a comprehensive wardrobe economy accounts for total cost of ownership including maintenance, repair, and potential residual resale value:
If estimating care costs accurately for an individual piece is difficult, leave maintenance costs out and evaluate simple purchase-to-wear efficiency. The goal is clarity, not mathematical perfection.
Comparing Realistic Wardrobe Scenarios
Price alone does not define value. Consider these realistic wardrobe comparisons:
A high purchase price does not automatically make an item expensive if it serves as a daily staple, whereas an impulse purchase on sale can be one of the most expensive items in your closet on a per-wear basis.
Why Every Additional Wear Lowers Long-Term Cost
Because fixed acquisition costs are amortized over every subsequent wear, continuing to wear clothes you already own is the single most effective way to lower cost per wear. Strategic repairs, such as resoling quality boots or mending a seam, add minimal cost while dramatically extending the garment’s lifespan.
Understanding the Metric Limits
Cost per wear is a financial usage metric, not a complete environmental or ethical audit. It does not measure supply chain fairness, fabric sustainability, or how comfortable an item feels. Use CPW as one practical tool to guide purchasing decisions and maximize the utility of your existing wardrobe.
