Type what goes in the envelope and what you paid for each supply. The calculator adds the typical weight, the USPS stamped-letter price from the same table our label generator uses, and your supplies, for one order and, if you like, for a month of orders.
Embed it on your site
Run a card shop site, a seller blog or a Discord guide? Paste these two lines where the calculator should appear. It draws itself in its own box, so it won't change your page's styles. It sets no cookies, stores nothing and sends nothing; the only link is a small "Powered by TCG Speed Shipper" credit.
What it counts
- Weight: cards at 1.8 g, penny sleeves at 0.6 g, toploaders at 7.3 g and a #10 envelope at 5 g, plus anything else you add (sources below). The weight calculator uses the same numbers.
- Postage: the USPS stamped First-Class Mail letter price. A toploader makes the envelope rigid, so the nonmachinable surcharge is added. Over 3.5 oz it is a package, and package postage depends on distance.
- Supplies: only the prices you type. Nothing is guessed.
Not sure the order can go in an envelope at all? Check with PWE or tracked? first: TCGplayer requires tracking over $49.99.
FAQ
Where do the stamp prices come from?
USPS Notice 123, the stamped First-Class Mail letter prices: $0.82 for the first ounce, $0.29 for each additional ounce, and a $0.49 nonmachinable surcharge for a rigid letter (USPS Notice 123 (price list)). Our label generator uses the same table.
Why are the supply prices empty?
Supply prices depend on where and how much you buy. Type what you paid for each envelope, sleeve and toploader; the calculator adds them up and never guesses.
Can I put this calculator on my own site?
Yes. Copy the two lines under Embed it on your site. It loads one small script from tcgspeedshipper.com, sets no cookies, stores nothing and sends nothing. It shows a small Powered by TCG Speed Shipper link.
