Enter four border measurements and get the centering percentage on both axes plus the highest PSA grade centering alone allows.
Free tools for collectors
Both calculators work on numbers you enter and run in the browser. Nothing is stored, nothing is transmitted, and neither one asks who you are.
Sale price in, take-home out — commission, transaction fee, fixed fee, postage and packaging, with published rates or your own.
Raw price, graded prices, fees and shipping in — break-even multiple, expected gain and the one-grade-below outcome out.
Why there is no price lookup here
Every card price dataset in this hobby is licensed, and the licences forbid republishing the feed. A price tool built on someone else's numbers would either break those terms or quote figures we cannot stand behind, so this site gives the method instead — how card value is decided and how to find a real sold price yourself.
What the tools need from you
The centering calculator needs four border measurements in millimetres. The ROI calculator needs a raw sold price, two graded prices and the fee for the tier you can actually book. Every reference page behind those judgements is listed on the guides page; the grading cost comparison has the current tables, and is it worth grading explains which numbers matter most. Judge condition with the condition guide before either.
