# Card collection value calculator: what the whole box is worth

Paste the collection one card per line and this adds it up, sorts it, and tells you the part nobody expects: what share of the money is sitting in the top one, five and ten cards. That share is what decides your insurance and what you sell first.

| Top 5 | $3,310 | 79.0% | 19% |

| All 26 cards | $4,190 | 100.0% | 100% |

Sold today at 13.25%, the lot returns $3,635, which is 39%
on what it cost. One card is 43.0% of this collection. Check it against your policy’s per-item cap
before anything else. Postage, packing and listing time are per card and are not in the fee, so the tail of the
list nets less than this.

The median comes from the same routine the [card value calculator](https://sportscardradar.com/tools/card-value-calculator/) uses,
taken across the whole list rather than the outlier-trimmed middle, because in a collection the outlier is the
point. Every figure updates as you type and none of it leaves the page.

***The first two cards of the worked example hold half the money; the last thirteen hold 4.7%.** The gold line is the cumulative value of the 26 cards in the panel above, sorted most valuable first; the dashed line is where that curve would sit if all 26 were worth the same. The gap between them is the only thing that makes a collection different from a pile of cardboard with a total attached. Computed from the list loaded in the calculator.

## The total is the least useful number here

A collection has two numbers and only one of them ever gets said out loud. The total is the headline. The distribution
is the one that decides what you insure, what you list first, and whether the boxes in the cupboard are worth the
weekend it would take to sell them.

In the worked example the 26 cards come to $4,190 against a cost basis of $2,615, so the collection is
$1,575 up on paper. Underneath that, 2 cards carry half the value, the top five carry
79.0% and the top ten carry 91.5%. The remaining 16 cards together are worth
8.5% of the collection — less than the rounding error on the top card.

That is not an artefact of a small example. Add four thousand commons to the bottom of the list and the concentration
gets sharper, not flatter, because every card you add to the tail adds a few cents to the total and another line to the
inventory. The median card in this list is $42.50 and the average is $161; the average is the
total divided by the count, which is a fact about the total, and the median is the middle card, which is a fact about
what you own.

## Two cards, half the money

Sorting by value and running a cumulative total is thirty seconds of arithmetic that most collectors have never
done, and it reorders the whole to-do list. If 2 cards are half the collection, then the storage
upgrade, the photographs, the certification numbers and the insurance conversation are all about those
2 cards. Everything else is housekeeping, and housekeeping should be batched.

It changes the selling order too, in the opposite direction to instinct. The reflex is to start with the bulk,
because it is in the way. The arithmetic says start with the top of the curve, where a single listing carries
43.0% of the value and the [platform fee](https://sportscardradar.com/tools/ebay-fee-calculator/) is the only real
cost. The tail is where postage, packing and the per-order fee eat the sale, which is the case the
[route comparison](https://sportscardradar.com/tools/where-to-sell-calculator/) exists to make: a bulk buyer paying a fraction of
comp for the bottom two hundred cards frequently beats listing them, once the time is priced at anything above zero.

## So what do you actually insure?

You insure the cards that sit above your policy’s caps, and you photograph the rest. Homeowners and renters policies almost always cap collectibles far below the contents limit, and the cap is usually per loss rather than per item. The number to find is the collectibles sub-limit in your own policy, not the contents figure on the front page. That is the number to find before you decide anything, and it is rarely on the front page of the policy.

The concentration figure is what turns that into an answer. A collection where the top card is 43.0% of
the total has one card to schedule and a general sub-limit that covers the remainder; a collection where the top forty
cards are evenly matched has a very different and much more expensive conversation ahead of it. The
[insurance gap calculator](https://sportscardradar.com/tools/insurance-calculator/) takes the total from this page, your own
sub-limit and your own rider rate, and prints the uncovered balance — including the failure that surprises people
after a loss rather than before one, where the collection is covered and the single card that mattered is not.

*Where the value sits in the worked example, read at five points*

| Sorted by value | Cumulative value | Share of the value | Share of the cards |
| --- | --- | --- | --- |
| Top 1 cards | $1,800 | 43.0% | 4% |
| Top 5 cards | $3,310 | 79.0% | 19% |
| Top 10 cards | $3,835 | 91.5% | 38% |
| Top 13 cards | $3,992 | 95.3% | 50% |
| All 26 cards | $4,190 | 100.0% | 100% |

Computed from the 26 lines loaded in the calculator above. The highlighted row is the half-way point by count: half the
cards, 95.3% of the money.

Your own five rows will hold different numbers and they will usually hold one of three shapes, each of which implies a
different next move.

*Three curve shapes, and what each one says to do next*

| If the top card is | The collection is | Insure | Sell |
| --- | --- | --- | --- |
| A third or more of the total | One asset with a hobby attached | Schedule that card by name and certification number | One decision, made deliberately, about one card |
| Under a third, with the top ten at 80–90% | Comfortable, and the easiest shape to sell down | A rider covering the top ten, photographed | Individually, from the top of the curve, over months |
| Barely above the median card | A bulk position, not a list of cards | The general contents limit, and nothing scheduled | In lots. Pricing it card by card is the largest waste of time in this hobby |

The highlighted row is the one the worked example falls into: its top card is 43.0% of the collection
and its top ten are 91.5%. Run your own list through the panel and the same three numbers pick your row.

## What the tail actually pays

The panel's “if sold today” line charges one fee to every card, which flatters the bottom of the list. What a card
really keeps depends on the postage its value forces, and postage does not scale with the card. Shipping each card by
the cheapest method in this site's [shipping reference](https://sportscardradar.com/tools/shipping-calculator/) that its value allows,
the top card here keeps 86.1% of its sale price and the bottom one keeps 16.8%.

***A card has to sell for $1.61 before the seller keeps anything at all, and no card ever keeps more than 86.75%.** The gold line is what is left after the 13.25% fee, the $0.40 per-order fee and postage, with each card shipped by the cheapest method its value allows; it breaks at every postage threshold, because the next tier of postage arrives all at once. The pale dots are the 26 cards loaded in the calculator above. Fee schedule read 2026-09-11; postage figures are starting values, not quotes. Free to reuse with a link to this page*

*The worked collection split by the postage each card's value forces*

| Postage tier | Cards | Gross | Net | Kept | Share of value |
| --- | --- | --- | --- | --- | --- |
| Plain white envelope (PWE) | 9 | $72.00 | $49.88 | 69.3% | 1.7% |
| PWE with tracking | 5 | $171 | $136 | 79.7% | 4.1% |
| Bubble mailer with tracking | 7 | $637 | $515 | 80.8% | 15.2% |
| Tracked and insured parcel | 5 | $3,310 | $2,809 | 84.9% | 79.0% |
| All 26 cards | 26 | $4,190 | $3,510 | 83.8% | 100% |

Computed one card at a time rather than as one fee on the total, which is why the last row is $3,510 against
the $3,635 the panel prints. The highlighted tier is the bottom of the list: 9 cards
that between them are 1.7% of the collection and keep 69.3% of what
they sell for.

## Building the list without a spreadsheet

1. **Start at the top and stop early.** Price the twenty most valuable cards individually from sold comps, one at a time, with the [value calculator](https://sportscardradar.com/tools/card-value-calculator/). Those twenty are almost certainly more than 90% of the total, and the precision you spend anywhere else is decoration.
2. **Keep raw and graded separate.** A slabbed copy and a raw copy of the same card are different products with different buyers. Enter them as separate lines with their own values, never as one line averaged between them.
3. **Write the cost down while you still remember it.** A cost basis you did not record is a gain you cannot evidence, to an insurer or to anyone else. If a card was graded, the cost is the purchase plus the [all-in submission cost](https://sportscardradar.com/tools/grading-cost-calculator/), not the fee alone.
4. **Count bulk in lots.** One line reading “four monster boxes, 3,200” is more accurate than 3,200 lines at a dollar each, because the second version prices every card at a number nobody will pay for the box.
5. **Date the file.** Put the date in the first line as a comment. A valuation without a date cannot be used for a claim, a sale or a tax position, and the whole exercise takes twenty minutes to repeat.

## What this total is not

- **It is not what you would be paid.** Every route to cash takes a cut, and the cut on the tail is proportionally much larger than the cut on the top card. The panel’s “if sold today” line applies one fee to everything, which flatters the bottom of the curve.
- **It is not an appraisal.** An insurer or an executor wants a valuation with a method, a date and evidence per card. This is the arithmetic layer underneath such a document, not a substitute for one.
- **It is not a return.** A collection worth more than it cost has not necessarily gained anything, because the money it was bought with has moved too. That is what the [inflation calculator](https://sportscardradar.com/tools/inflation-calculator/) answers, and the [ROI calculator](https://sportscardradar.com/tools/card-roi-calculator/) puts a rate on it.
- **It is not a reason to under-protect the tail.** The bottom of the curve is cheap to replace and cheap to ruin, and a bent corner in a full box is how a card leaves the top ten. The [supplies calculator](https://sportscardradar.com/tools/supplies-calculator/) prices sleeves, toploaders and boxes per card, which is the honest way to look at that spend.

## Bottom line

To value a card collection, price the top twenty cards individually from sold comps, count everything else in lots, and
add the two together — then sort the list and look at where the money actually sits. In the worked example on this page,
2 of 26 cards hold half the value, the top five hold 79.0% and the bottom
16 hold 8.5% between them. That concentration, not the total, is what decides the three
things a collector does next: which cards to schedule on an insurance policy, which cards to sell individually and
which to move as bulk, and how much of your attention the rest of the boxes deserve. Reference figures on this page are
dated 2026-09-11; the fee is an input because it changes and this page does not.

## Questions this tool gets asked

How do I work out what my whole card collection is worth?

Price the cards individually and add them up, in that order. There is no shortcut that produces a defensible total, because a collection is not a commodity with a unit price: it is a list of separate small markets. The practical method is to value the top twenty or thirty cards from sold comps one at a time, count the rest in lots at a per-card figure you would genuinely accept, and add the two together. The tool on this page does the adding, the sorting and the concentration arithmetic once you have the list.

Why does the top card matter more than the total?

Because almost every decision you make about a collection is a decision about a handful of cards. In the worked example loaded above, the single most valuable card carries 43% of the value and the top five carry 79%, so the insurance question, the storage question and the selling question are all questions about five cards. The other twenty-one are an inventory problem rather than a money problem, and treating them as if they were the same thing is what makes collectors spend a weekend listing commons.

What is a cost basis and why does the tool ask for it?

The cost basis is what you paid, including what you paid to get the card graded and shipped. Without it the tool can tell you what a collection is worth and nothing at all about whether you are up or down, which is the question most people actually came to answer. Enter it as the third number on each line. Lines with only one number are counted towards the value and left out of the cost basis, and the panel says how many lines were treated that way.

Should I use the price I paid or the current value for insurance?

Neither, on its own. A scheduled-items rider is written against a stated value that you have to be able to evidence, so the figure you give an insurer needs a dated valuation behind it — sold comps for the named cards, plus the certification numbers of anything slabbed. The total from this tool is the starting point for that conversation rather than the end of it, and the per-card concentration is the part an underwriter cares about, because one card above the per-item cap is the common way a covered collection turns out not to be.

Does the median card value tell me anything useful?

It tells you what you actually own, as opposed to what you are worth. In the worked example the median card is $42.50 and the average is $161, and the gap between those two numbers is the whole story: the average is the total divided by the count, so it is a fact about the total, while the median is the middle card in the list. When the two differ by a factor of three or more, the collection is a few significant cards plus a filing system, and it should be handled that way.

How should I value bulk commons?

Count them, do not price them. Take a per-card figure you would genuinely accept for the box in one transaction, multiply, and enter it as a single line. Pricing commons individually from sold listings produces a number that is both large and unobtainable, because nobody is going to buy four thousand cards one at a time at those prices and the postage on each of them exceeds the card. A single honest bulk line is more accurate than four thousand optimistic ones.

How often should I re-run this?

Once a quarter is enough for most collections, and after any event that changes a top-five card — a grade coming back, a player retiring, a set being reprinted. The reason to date the exercise rather than to keep a rolling number is that an insurance claim and a tax position both need a valuation with a date on it, and a spreadsheet that has been edited continuously since 2019 has no date on it at all.

Is anything I paste here uploaded or stored?

No. The parsing, sorting and arithmetic all happen in JavaScript that arrived with the page, the same way the rest of the calculators on this site work. There is no request to any server while you type, nothing is written to your browser storage, and closing the tab disposes of the list. If you want the numbers to persist, keep the text file you pasted from.
