Those pennies add up. Calculate the true cost of every toploader, label, and mailer to know exactly what you're spending per package.
How this works:
- Enter the Total Cost and Quantity you bought (e.g., $27.50 for box of 50 toploaders).
- We calculate the unit cost and multiply by how many you use per shipment.
- Add custom items for extras like thank-you cards or stickers.

Breakdown
Knowing your exact material cost helps you price your shipping correctly and protect your margins.
Toploaders, sleeves, team bags, mailers, and labels each cost only pennies — but across hundreds of shipments those pennies quietly eat your margins. This free calculator turns what you paid for supplies into a precise cost per package, so the number is no longer a guess.
Enter the total price and quantity for each supply, set how many you use per order, and add custom items for anything extra you include. You’ll get your material cost per shipment and per 100 orders, plus a live unit-cost view that makes bulk-buying decisions obvious.

Frequently asked questions
How much does it cost to ship a trading card?
The materials — penny sleeve, toploader, team bag, bubble mailer, and label — usually add up to a small but real amount per package, and it adds up fast across hundreds of orders. This tool computes your exact material cost from what you actually paid. Postage is separate and depends on weight and service.
What supplies do I need to ship cards safely?
A common safe kit is a penny sleeve and a toploader inside a team bag, shipped in a bubble mailer; lower-value cards often go in a plain white envelope (PWE) with a sleeve and a piece of cardboard. The calculator’s default rows cover this standard kit, and you can add your own.
How do I price shipping so I don’t lose money?
Add your per-package material cost to your postage, and make sure that total is covered by the shipping you charge or built into your price. The eBay and Whatnot fee calculators include a shipping-cost field for exactly this, so your net profit reflects supplies too.
Does buying supplies in bulk lower my cost?
Yes. Your unit cost is the total you paid divided by the quantity, so larger packs lower the cost per card. The calculator shows your live unit cost as you type, making it easy to compare bulk pricing before you buy.
