Pokémon investment returns: subtract fees before inflation
Calculate card-investment performance from cash paid and retained sale proceeds, not app valuations or selected record auction prices.
Why headline gains need context
Public discussion often compares a card’s recent quoted value with an older purchase price. That can omit shipping, grading, transaction charges, tax, and the difference between a listing and a completed sale. This analysis supplies a calculation framework rather than endorsing a marketplace price index or claiming a measured market-wide return.
Define the cash flows
Record the purchase date, amount paid, acquisition expenses, later grading or storage, sale date, and net payout. Marketplace charges can vary by category, account, location, and transaction details. eBay publishes fee tables; use the applicable schedule rather than assuming one universal rate. A collection app’s estimated total is not a bank balance.
A worked real-return calculation
Suppose total acquisition and holding cost is $500, with $650 gross sale proceeds and $100 selling costs one year later. Retained proceeds are $550, a 10% nominal return on the $500 simplified outlay. With 4% inflation, real return is 1.10 / 1.04 − 1, about 5.77%. If costs were higher, the answer would change.
Comparing a collection with an index
Include unsold, damaged, unpopular, and losing positions rather than only successful sales. Match currencies and dates, and use consistent valuations when no transaction occurred. An index selecting liquid high-value cards can differ from a casual collection. Statistical comparisons also need dividends for equity benchmarks and comparable cost assumptions.
What this means for inflation claims
A large auction sale establishes a price for that item at that event, not proof that the whole category protects buying power. The inflation calculator helps compare dollar dates, while the return guide covers percentages. Treat financial and collecting objectives as separate reasons to own a card.
