An estimate from Podly's sales model, not Amazon data. A rank changes through the day as sales come in, so check it more than once.

## How we calculate this

The tool uses the same sales model as the Podly app. Each marketplace has a curve from rank to monthly sales in its main clothing category, set for a standard T-shirt. A rank in another category is first converted to the matching rank in the main category, then read on that curve.

**Monthly sales**

Podly sales model (marketplace, category, BSR)

**Sales per day**

monthly sales ÷ 30

**Royalty per month**

monthly sales × your royalty per sale

This is Podly's estimate, not data from Amazon. Amazon describes its Best Sellers lists as "based on sales" and "updated frequently", so the rank you see is a snapshot.

## How to use the Amazon sales estimator

1. Open the product on Amazon and scroll to **Product information**. Find "Best Sellers Rank".
2. Pick the same marketplace, and the category the first rank is listed in. For a Merch shirt on Amazon.com, that is usually Clothing, Shoes & Jewelry.
3. Type the rank. Commas are fine. The estimate updates as you type.
4. Add your royalty per sale to see what that rank earns in a month and a year.

## What the Best Sellers Rank tells you

Amazon ranks products in each category by their recent sales. Its [Best Sellers page](https://www.amazon.com/Best-Sellers/zgbs) calls the lists "our most popular products based on sales" and says they are "updated frequently" (checked November 14, 2026). A lower number means more sales, but the scale is steep: the gap between rank 1,000 and 10,000 is worth far more sales than the gap between 500,000 and 510,000.

The category matters as much as the number. A rank of 100,000 in Clothing, Shoes & Jewelry on Amazon.com is a steady seller. The same 100,000 in a small category may be a few sales a month.

## Worked example

A Merch T-shirt on Amazon.com shows "#100,000 in Clothing, Shoes & Jewelry". Podly's model estimates about 614 sales a month, or about 20 a day. At a $2.44 royalty, the royalty Amazon lists for a standard T-shirt at $19.99 in the Creator group, that is about $1,498 a month while the rank holds.

Ranks move every day, so treat one reading as a hint. A product that holds a rank for weeks is a much stronger signal than one that touched it once.

## Mistakes to avoid

- **Mixing categories.** Use the rank and category shown together. A sub-category rank is not a main-category rank.
- **Trusting one snapshot.** A single sale can lift a slow product for a few hours.
- **Copying a best seller.** High sales show demand for a niche, not permission to copy a design. Check trademarks before you upload.

To see the rank history and estimated sales of any Merch product, open it in Podly's [product details](https://podly.co/features/products-details/), or search the whole catalog by sales in the [Merch Database](https://podly.co/features/merch-database/). Work out your royalty first with the [Merch royalty calculator](https://podly.co/royalties-calculator/).

## BSR and sales questions, answered.

Something we missed? [Send us a message.](https://podly.co/contact/) A human answers.

**01 How many sales is a BSR of 100,000?**

For a T-shirt ranked in Clothing, Shoes & Jewelry on Amazon.com, Podly’s model estimates about 614 sales a month, or 20 a day. The same rank in a smaller category means far fewer sales, so pick the category the rank is shown in.

**02 How accurate is a BSR to sales estimate?**

It is an estimate. Amazon does not publish sales numbers, and a rank only compares a product with the others in its category. Use it to compare designs and niches, not to forecast an exact income.

**03 How often does Amazon update the Best Sellers Rank?**

Amazon says its Best Sellers lists are based on sales and updated frequently. A rank can jump after one sale and slide back within hours, so check a product several times or look at its rank history.

**04 Why does the estimate say 5,000+?**

Very high ranks are at the top of our model, where a few places can mean hundreds of sales. We show the cap with a plus sign instead of guessing a precise number.

**05 Does this work for Amazon Merch on Demand?**

Yes. The model is set for a standard T-shirt, the product most Merch sellers research. Enter your royalty per sale to turn the sales into monthly royalties.
