Birkin ROI Calculator
What is your Birkin worth today?
Calculate the current resale value of your Hermès Birkin against your purchase price, then compare its appreciation to the S&P 500 over the same period. Built on 1,100+ live authenticated listings — refreshed hourly.
How it works
We pull the median resale price for the matching (size, leather) cohort across our 12-merchant index and compare it to your purchase price. Then we benchmark against the S&P 500 cumulative total return over the same window — the apples-to-apples question every investor asks.
- Cohort median. Trimmed-mean of all live Birkin listings matching your exact size and leather. Excludes top + bottom 5% to filter outliers (extreme HSS, exotic leathers, damaged sales).
- Your appreciation. Current cohort median minus your purchase price, expressed as a percentage and annualized.
- S&P 500 benchmark. Approximate cumulative total return from your purchase year through today.
- Verdict. Outperformed / matched / under-performed S&P 500, plus 6 lowest-priced cohort listings if you're considering buying another.
This is editorial market commentary, not financial advice. Birkin appreciation is illiquid and depends on condition, accessory completeness, and merchant fees at the moment of sale.
