Designer Resale Calculators
Free, practical calculators for buying and selling pre-owned designer fashion — resale value, consignment payouts, depreciation, size conversion, cost-per-wear, and authentication scoring. Educational tools for pricing and vetting resale, not financial, legal, or professional authentication advice.
Resale Value Estimator
Estimate a realistic resale price for a pre-owned designer piece from its brand tier, condition grade, age, and original retail — the number to anchor a listing or an offer
Consignment Payout Calculator
Turn a sale price and a platform's tiered commission into your real net payout, so you know what a consignment or marketplace sale actually leaves you with
Designer Depreciation Calculator
Model how a designer piece loses — or keeps — value across the years you own it, showing current worth and the percentage of retail retained by brand tier
Luxury Size Converter
Convert between designer, EU, US, and UK sizing for apparel and shoes so a secondhand size in an unfamiliar system tells you whether the piece will fit
Cost-Per-Wear Calculator
Divide a piece's true cost — price minus expected resale — across how many times you will wear it, the honest test of whether luxury is worth it
Authentication Checklist Scorer
Run a category-specific checklist across stitching, hardware, serials, and paperwork to get an authenticity confidence score before you buy or sell
