Grading looks like free money from the outside. Send a card away, get it back in a plastic slab with a number on it, and watch the price multiply.
That is roughly what happens to the cards you see in headlines. It is not what happens to most of the cards people actually submit, and the difference between those two outcomes is where the money goes.
The decision is a maths problem rather than a judgement call, which is good news, because maths problems have answers.
What You Are Actually Paying For
Grading is an authentication and condition service. A card goes to PSA, CGC or BGS, gets assessed on centering, corners, edges and surface, then comes back sealed with a grade from one to ten.
The value comes from removing an argument. A raw card described as near mint is somebody’s opinion, while a graded card is a documented assessment that a buyer can price without inspecting anything.
That certainty is worth real money, and the premium it commands has grown rather than shrunk as the hobby has matured.
The Premium Is Bigger Than It Used to Be
Across cards that are plausible grading candidates, meaning raw values of roughly twenty dollars and up, a PSA 10 now sells for around 11.8 times the raw price. That figure sat closer to 9.3 times back in 2021.
So the upside has genuinely improved. The problem is that the multiplier only applies to the top grade, and a PSA 9 on the same card is worth a fraction of it.
Expected value is what matters here, not the best case. A grading ROI calculator handles that properly by weighting every possible outcome against its likelihood, taking the card, your realistic grade probabilities and the fee tier you are using, then returning an expected profit per submission rather than a fantasy figure based on a perfect ten.
It uses real PSA 9 and 10 sale figures where they exist and a typical taper below the top grade where they do not, which keeps the middle outcomes honest.
The Fees Are the Part People Underestimate
Costs vary considerably by service and turnaround. CGC starts around eighteen dollars a card and BGS around twenty, while PSA’s cheaper tiers land near fifty dollars plus roughly twenty in shipping and insurance.
Faster PSA tiers climb steeply from there. The published service levels run from regular pricing up into the hundreds and beyond for premium turnaround, which is only rational for genuinely valuable cards.
Shipping both ways, insurance and the submission’s share of any bulk minimum all count. A seventy dollar all-in cost per card means a card needs to gain considerably more than seventy dollars to have been worth sending.
Where People Get It Wrong
The most expensive mistake is optimism about condition. Cards that look flawless under a desk lamp routinely come back as nines because of centering that the eye does not register.
Modern cards are especially brutal on this, since print runs are enormous and gem rates are high, which means the population of tens is large and the premium for one is correspondingly thinner.
Cheap cards almost never justify the fee. A ten dollar card that triples in a slab has still lost money once you count grading, postage and the months it spent away.
When It Clearly Does Make Sense
Vintage cards with genuine scarcity are the obvious case, because the gap between a raw copy and a graded one is wide enough to absorb the fee several times over.
Authentication value matters too. For older and higher value cards, a slab is partly a defence against counterfeits, and that reassurance is a large part of what buyers are paying for.
Cards you intend to keep are a different question entirely. Slabbing something for protection and display is a perfectly reasonable thing to do, and it does not need to return a profit to be worth it.
A Sensible Process
Check what the card sells for raw, then check what it sells for at a nine and a ten, using completed sales rather than asking prices. Then be pessimistic about your own grading odds.
Run the expected value with the real fee you will pay rather than the headline tier price, and only submit if the number still works when you assume a nine.

Key Takeaways
Grading pays when the raw to graded gap is wide, the card is likely to grade well and the fee is small against the result. It loses money quietly in every other case.
Run the expected value before the submission rather than after, weight it across all the grades you might realistically get, and accept that most of a collection is not worth sending anywhere.
That is not a pessimistic conclusion. It just moves the money toward the handful of cards where grading actually changes something.
