Calculators
Each calculator shows its formula, units and assumptions. Nothing is estimated for you in secret.
Resale value estimator
Applies a yearly retention rate you choose to a purchase price, and shows the cost of ownership.
value after n years = price x (retention rate) ^ n; cost of ownership = price - value
Assumptions
- A single retention rate is applied every year, compounding. Real used markets move in steps, not smooth curves.
- Condition, box, papers and service history change a real resale price more than age does.
This projects your own assumption forward. It is not a market valuation and not an appraisal.
Landed cost calculator
What a cross-border order really costs once shipping, duty and tax are added.
landed cost = (item price + shipping) + duty + tax, where duty = item price x duty rate, and tax = (item price + shipping + duty) x tax rate
Assumptions
- Duty is applied to the item price only; tax is applied to item price plus shipping plus duty. Some countries tax shipping differently, and a few apply duty to the shipping too.
- Rates are the ones you enter. This calculator does not know your country's current duty schedule or de minimis threshold.
- Currency conversion, card fees and any prepayment discount are not included.
This is arithmetic on your own figures, not a customs ruling. The carrier or customs authority decides the final amount.
Cost per wear calculator
Price divided by the number of wears you realistically expect, with cleaning and repair added.
cost per wear = (price + cleaning cost per year x years + repairs) / (wears per month x 12 x years)
Assumptions
- Seasonal items are worn only in their season, so enter wears per month across the whole year, not just the months you wear it.
- Resale value is not subtracted. Use the resale calculator for that.
A comparison figure between two garments, not a prediction of how long something will last.
