Shipping is one of the top three places Etsy sellers lose money. Underpricing on a heavy or international order eats margin faster than anything except free shipping on a product that cannot support it. This calculator ballparks real postage so your charge does not leave money on the table.
Rates are 2026 USPS retail estimates, reviewed quarterly. Use as ballpark, confirm at label purchase. International, insurance, and packaging cost all handled.
Step 1 of 3: Package
Packed weight including box.
Step 1 of 3
Tumbler weighs 10oz, shipped in an 8x5x5 box with bubble wrap totaling 14oz. Domestic US, cheapest carrier. Packaging $0.85. You charge the buyer $7.
USPS Ground at 14oz is $7.45. Plus $0.85 packaging = $8.30 actual. You charged $7, so you are eating $1.30. The calculator recommends $8.80 to buyer to keep margin intact. Many sellers undercharge on tumblers by exactly this amount.
Adult tee in a poly mailer. 7oz packed. 10x7x1 flat package. USPS Ground only. Packaging $0.50. You charge $5.50 flat.
USPS Ground at 7oz: $5.85. Plus packaging $0.50 = $6.35 actual. You charged $5.50, so you are eating $0.85. Recommended charge $6.85. Shirt sellers on Etsy with free shipping need to bake in $7 to $8 to cover this honestly.
30oz tumbler shipped to Canada. Packed 18oz. 9x5x5 box. Packaging $1.25. Insurance on $75 value, which USPS already covers under its included limits. You charge $25.
International at 18oz: $32 base. Plus packaging $1.25. Actual ship cost $33.25. You charged $25, eating $8.25 on this order. International buyers often expect to pay real shipping; charging $34 is fair and expected.
Three parts: base postage (weight and destination), insurance if added, and packaging. Base postage is the biggest driver. Packaging is usually under 10% of total. Insurance matters on higher-value or fragile orders.
| Weight | USPS Ground | Priority |
|---|---|---|
