How to Use Cost-Per-Wear to Decide if a Purchase Is Worth It
Published 2026-07-18 · Aroha Radiance Editor
Cost-per-wear turns a single price tag into an ongoing cost, so you can compare a splurge you'll wear constantly against a bargain that will sit in the back of the closet. This guide walks through the method with three worked examples and the assumptions behind them.
The formula
Cost-per-wear = item price ÷ total expected wears.
Total expected wears is estimated as how many times per month you'll realistically wear the piece, multiplied by 12 months, multiplied by how many years you expect to keep wearing it. The calculator on this site uses that same estimate: it doesn't track actual wears over time, it projects them upfront so you can decide before you buy.
Worked example 1: a silk saree bought for weddings
Price: LKR 45,000. Expected use: twice a month during wedding season, kept for 10 years.
Total expected wears: 2 × 12 × 10 = 240. Cost-per-wear: 45,000 ÷ 240 = LKR 187.50.
A saree that looks expensive on the price tag can land in 'solid investment' territory once its long usable life is factored in. The calculator's tiers are scaled separately for LKR/INR versus other currencies precisely because raw price ranges differ so much between them.
Worked example 2: a going-out top bought for one event
Price: LKR 3,500. Expected use: once, for a single party.
Total expected wears: 1. Cost-per-wear: LKR 3,500.
This is the scenario cost-per-wear is best at catching: a low price tag can still be a poor cost-per-wear if the realistic wear count is very low. If you genuinely expect to rewear it a few more times, plug in that more realistic number. The result changes quickly with small changes to wear count when the count is this low.
Worked example 3: everyday sandals
Price: LKR 6,000. Expected use: 20 times a month, kept for 2 years.
Total expected wears: 20 × 12 × 2 = 480. Cost-per-wear: 6,000 ÷ 480 = LKR 12.50.
High-frequency basics almost always land in 'green light' territory even at a mid-range price, because the wear count grows so much faster than an occasion-only piece.
Assumptions this method makes
It assumes your estimated monthly usage and ownership period are realistic, not aspirational: overestimating either will understate the true cost-per-wear.
It treats every wear as equally valuable. A piece worn to one important event may be worth more per wear than the arithmetic suggests.
It uses the purchase price only. It does not add tailoring, dry-cleaning, or storage costs. For delicate or formal pieces where care costs are significant, add those to the price mentally before entering it.
Limitations
Cost-per-wear is a planning estimate, not a guarantee. Actual wear counts depend on how your wardrobe, body, or style preferences change over the ownership period.
It's a comparison tool, not a spending rule. A high cost-per-wear isn't automatically a bad purchase if the piece serves a purpose beyond frequent wear, such as a wedding outfit or a family heirloom.
