How to Price Custom Tumblers for Profit
Custom epoxy tumblers are one of the hottest crafts to sell online, but too many makers price by gut feeling and end up working for pennies. This calculator breaks down every cost so you can set prices that actually pay you what you're worth.
The Math Behind Tumbler Pricing
Your true cost per tumbler is the sum of three things: the blank tumbler, the epoxy and decorations (glitter, vinyl, mica powder), and your labor time. Most makers forget that last piece. If you spend 45 minutes on a tumbler and your time is worth $20/hour, that alone adds $15 to the cost.
Why the 2.5x Markup Works
The suggested sell price uses a 2.5x multiplier on your total cost. This is not pure profit. It covers marketplace fees (Etsy takes roughly 12-15% after listing, transaction, and payment processing fees), packaging materials, shipping supplies, and the occasional remake when a tumbler cures with a bubble or hair in the finish.
Pro Tip: Track your epoxy cost per ounce, not per bottle. A $25 kit that yields 16 oz of mixed resin costs about $1.56/oz. Knowing that number lets you price any size tumbler instantly without guessing.

Frequently Asked Questions
How much epoxy resin do I need per tumbler?▼
Most standard 20 oz tumblers require between 1.5 and 3 oz of mixed epoxy resin. Thicker coats or multiple layers will use more. Always mix slightly extra to account for drips and waste.
What is a good profit margin for custom tumblers?▼
A 2.5x markup on your total cost (materials + labor) is a solid starting point. This gives you roughly a 60% profit margin, which accounts for marketplace fees, packaging, and shipping supplies.
Should I include my time when pricing tumblers?▼
Absolutely. Many makers undercharge because they forget to pay themselves. Include prep, applying glitter or vinyl, epoxy coating, curing time monitoring, and finishing. A fair hourly rate ensures your business is sustainable.
