How to create a listing on Mercado Livre in 2026: listing type, price, and a step-by-step guide to avoid losses

Creating a listing on Mercado Livre is free: you only pay when you make a sale. The charges are the category commission (10% to 14% for Clássico, 15% to 19% for Premium) plus shipping costs, which depend on the package weight and price range. To create a listing, choose a category, write a title, upload photos, fill in the product details, set the price, stock, and shipping, then choose a listing type. The step that causes the most losses is the one most sellers skip: calculating the price before publishing.

I'll go through the steps in the order they appear on screen and explain what affects the result at each one.

#The three listing types

Rules checked in the help center in October 2026. Free listings are for selling unwanted items or testing the platform; regular sellers use Clássico or Premium. MercadoLíder sellers can't use Free listings. I break down the numbers for the two paid options in Clássico or Premium: which one is more profitable?

#Step-by-step guide to creating a listing

1. Choose the right category

The category determines the commission and the product details fields. Choosing the wrong category can cost you a few percentage points in commission and keep your listing out of the filters buyers use. If Mercado Livre suggests a category based on your title, make sure it matches your product.

2. Write a title buyers will search for

The title is the main search signal. Start with the product name the way people type it, then add the features that set yours apart: size, material, quantity, compatibility. Avoid words that don't describe the product ("promotion," "deal," "the best") and repeated terms.

3. Photos that sell and prevent returns

The first photo earns the click. Show the whole product against a clean background with good lighting. Use the next photos to show details, measurements, what's in the box, and the product in use. A photo that doesn't match the product can lead to a return for "not as described." You pay for it, and it hurts your reputation. I break down the cost in returns on Mercado Livre: what sellers pay.

4. Complete product details

Product details (brand, model, measurements, material, voltage, compatibility) power search filters. Listings with incomplete details disappear when buyers filter results. Fill in every field the category asks for, even optional ones.

5. A description that answers questions

Use the description for details the photos and product fields don't cover: how to use it, warranty, what's in the package, and care instructions. Every question you answer there means one less question and one less mistaken purchase.

6. Stock and lead time

List only the stock you actually have. Selling an item you don't have leads to cancellations, which hurt your reputation. If the product is made to order or arrives from your supplier periodically, set a handling time (up to 60 days), keeping in mind that longer times reduce visibility.

7. Shipping and package dimensions

Enter the weight and dimensions of the package that actually leaves your stock. Shipping costs are calculated using whichever is greater: actual weight or dimensional weight (height × width × length ÷ 6,000). Incorrect measurements throw off your margin.

8. Price: the step most sellers skip

Before publishing, calculate three numbers: the floor (the price where profit is zero), the target (the price that gives you the margin you want), and the ceiling (the most the market will accept). The formula is:

Price = (product cost + packaging + shipping cost) ÷ (1 − commission − tax − margin)

For a product that costs R$ 25, weighs 300 grams, and has a 12% commission and 6% tax, the price for a 15% margin is R$ 50,37. See the step-by-step guide, including how to account for shipping price ranges, in the selling price formula.

#What happens after you publish

• Your listing appears in search and starts getting visits. In the first few days, price and shipping have a big impact on conversion.
• Questions will come in. Responding quickly increases your chances of making a sale.
• Your first sale reveals the real cost. Check the sale details to see the commission and shipping cost charged. If they differ from your estimate, the category or weight isn't what you expected.

In practice. A hardware seller posted 40 listings over a weekend, copying competitors' prices. In the first week, sales were strong. At the end of the month, they realized that 9 listings had shipping costs higher than expected because the items were long and their dimensional weight exceeded 3 kg. Those 9 listings had been losing money since the first sale. Measuring the box and calculating the price beforehand would have prevented the loss for the entire month.

#Three common listing mistakes

1. Copying a competitor's price without calculating your minimum. The competitor may have lower costs or may be selling at a loss.
2. Premium for a low-priced product. Below R$ 30, it doesn't offer installment payments. You pay 5 extra percentage points just for the added exposure.
3. Guessing the dimensions. They change the shipping cost for every sale.

#List with your price already calculated

To test a product's price before creating the listing, use the Milewa calculator. It applies the current shipping table and shows the price for the margin you choose.

If you publish a lot of listings, Milewa offers AI Listing Creation (on Pro and Scale plans). It creates a title, description, and product details, then publishes the listing paused so you can review it before activating it. The ideal price for your target margin appears on the Products screen. Once sales start, each order's margin appears alongside the commission and shipping cost actually charged by Mercado Livre.
