Pick your current Merch by Amazon tier (10 to 100,000 designs) and how many designs you have live to see remaining slots. Amazon does not publish the exact unit count that unlocks the next tier, so this tracks capacity, not a sales-to-unlock prediction.

Merch by Amazon (Merch on Demand) caps how many designs you can have live at once, and that cap rises in known steps as you move up tiers: 10, 25, 100, 500, 1,000, 2,000, 5,000, 10,000, 25,000, then 100,000. This page tells you how much room you have left in your current tier.
On the defaults, a Tier 25 seller with 10 live designs has 15 slots left, using 40% of the tier.
Amazon reviews an account's sales history to decide tier advancement, but has never published the exact number of units sold that guarantees a promotion, and that bar has reportedly shifted over time. Treat any tool that claims a precise unlock number with skepticism -- this one tracks the capacity you know, not the promotion you do not.
Pick your current Merch by Amazon tier (the published tier sizes are 10, 25, 100, 500, 1,000, 2,000, 5,000, 10,000, 25,000, and 100,000 live designs) and enter how many designs you currently have live. The page shows how many design slots you have left before you hit that tier's cap.
Amazon reviews accounts for tier advancement based on sales performance, but does not publish an exact unit-sold threshold that guarantees a promotion. Any calculator that claims a precise "sell N units to unlock" number is guessing. This page tracks your known, published tier capacity instead of inventing an unlock formula.
From smallest to largest: 10, 25, 100, 500, 1,000, 2,000, 5,000, 10,000, 25,000, and 100,000 live designs. Your dashboard in Merch on Demand shows your current tier and design count directly.
The tool flags that you are at capacity and reminds you to check your Merch dashboard, since Amazon (not this page) decides when and whether you move to the next tier.
