Garment Longevity Calculator
Expected wear life from fabric, care, and usage frequency.
About this calculator
This calculator estimates how many wears you'll get out of a garment by starting from a base lifespan figure for its fabric type — durable denim tops the list at 400 wears, followed by wool suiting at 300, cashmere at 250, cotton casual at 200, linen at 180, cotton dress at 150, silk at 120, and synthetic athletic wear at the low end with 100 wears — then adjusts that baseline for how you actually treat it. Care quality is a straight multiplier: poor care (hot machine wash, tumble dry) cuts expected life in half, while excellent care (hand washing or dry cleaning) extends it by 30%. Wash frequency works separately as a mechanical-stress factor, since every wash cycle physically stresses fibers regardless of water temperature — the calculator reads this input as wears between washes, so a low number here means frequent washing. Washing far more often than the once-every-three-wears baseline (a low wears-between-washes value, like washing after every single wear) pulls the factor down toward 0.4x, shortening the garment's projected life, while washing much less often (a high wears-between-washes value, like every 8-10 wears) pushes the factor up toward 1.5x, extending it.
Multiplying base wears by both factors gives an estimated total wear count, which the calculator then converts to months and years of service life using your wears-per-week input. From there it derives cost-per-wear (purchase price divided by total wears) and an annual ownership cost that adds depreciation to a care-cost estimate — home washing assumed at $0.75/cycle, dry cleaning at $8/cycle for the "excellent care" tier. These multipliers are directional estimates built from general textile-durability patterns, not lab-tested figures for your specific garment, so treat the wear-count output as a comparative planning tool — is this the more economical purchase — rather than a warranty.

Frequently Asked Questions
Why does washing less often extend the garment's estimated life?
The calculator treats wash frequency as a mechanical-stress factor separate from care quality — every wash cycle physically agitates and stresses fibers, so more frequent washing accumulates that stress faster over the same number of wears. The input is read as wears between washes, and the wash-stress factor is normalized so washing every 3 wears equals 1.0x; washing more often than that (a lower number) pulls the factor down toward 0.4x and shortens estimated life, while washing less often pushes it up toward 1.5x.
How is care quality different from wash frequency in this calculation?
Care quality and wash frequency are two independent multipliers applied to the same base lifespan. Care quality reflects wash and dry method — hot machine wash and tumble dry at 0.5x versus hand wash or dry clean at 1.3x — capturing how gently each cycle treats the fabric. Wash frequency instead captures how many cycles the garment endures overall, regardless of how gentle each one is, so a garment washed gently but very often can still see its estimated life pulled down by the frequency factor even with excellent care quality.
Why is cost-per-wear more useful than the purchase price alone?
Cost-per-wear divides purchase price by estimated total wears, so it directly compares a cheap garment with a short life against a pricier one built to last — a $200 pair of jeans expected to survive 400 wears works out to $0.50/wear, while a $40 synthetic top expected to survive only 100 wears comes to $0.40/wear despite the much lower sticker price. It's the number that actually reflects value per use rather than upfront cost.
What's included in the annual ownership cost figure?
Annual ownership cost adds two pieces: the garment's purchase price spread evenly across its estimated years of life (depreciation), plus an annual care cost estimate based on how many times per year you'd wash it (at $0.75 per home wash cycle, or $8 per cycle if you selected the excellent-care/dry-clean tier). It's meant to show the full yearly cost of keeping and maintaining the item, not just what you paid for it once.
