When to use this calculator

Use this when you need the real cost to ship a custom shirt, print or handmade item, and a shipping charge that still covers packing after marketplace fees on postage.

Packaging is box, fill and tape. Postage is the label you actually buy, plus insurance and any fuel surcharge. Packing minutes are labor. The recommended customer charge then covers those costs after the percent fee that platforms take on shipping.

How this calculator works

How we calculate this

  1. Packaging = box + fill + tape and label
  2. Postage = label + insurance
  3. Surcharge = postage × surcharge %
  4. Labor = packing minutes × hourly rate
  5. Your cost = packaging + postage + surcharge + labor
  6. Charge the customer = cost / (1 − handling margin − fee %) when valid

Example

Example: a shirt in a poly mailer

$0.85 mailer, $0.25 tissue, $0.20 tape and label, $8.50 postage, 8 minutes packing at $18/hr, 6.5% marketplace fee on shipping, 0% handling margin.

  • Packing labor is about $2.40 — often more than the mailer.
  • If Etsy takes a percent of shipping, charging exactly what you paid the carrier still loses money.
  • Set handling margin above 0 only if packing should profit, not just break even.

How much should I charge?

Charge the recommended shipping amount so postage and packing are not taken from product margin. If you offer “free shipping,” add this cost into the item price instead.

Pricing tips

  • Enter the postage from a real label, not a guess from last year.
  • Heavier hoodies and framed prints need their own postage input.
  • If you ship from a market booth, set marketplace fee to 0.

Common mistakes

  • Charging postage only and donating boxes, tissue and packing time.
  • Ignoring that marketplace fees often apply to shipping collected.
  • Using this as a live USPS rate quote — it is a cost planner.

FAQ

How do I calculate shipping cost for custom merch?

Add the mailer or box, fill, tape, the postage you pay, insurance, packing time and any fuel surcharge. Then raise the customer charge so marketplace fees on shipping still leave you whole.

Should I charge shipping separately or bake it into the price?

Either works if the dollars are in the quote. Separate shipping is clearer; “free shipping” must add this cost into the item price or you eat it.
