Mercado Libre gives you traffic but takes between 25% and 35% of your selling price in fees, shipping and Mercado Ads. Your own store gives you margin but needs advertising to bring in visitors. Which one is better for your profitability? The real answer comes from margin by channel, not sales volume. Here's the analysis, no fluff.
Why are most e-commerce stores in Argentina on both channels?
Mercado Libre is the channel with the most organic traffic in Argentina. For most categories, not being on Mercado Libre means not existing for a huge part of the market. But Mercado Libre's fees are one of the most underestimated hidden costs in local e-commerce.
At the same time, Tiendanube and Shopify are platforms with a low cost per sale but require investing in ads to bring in traffic — mainly Meta Ads and Google Ads. The cost doesn't show up in the platform fee; it shows up on the card you load your ad budget onto.
The problem is that most e-commerce owners look at sales volume by channel, not margin by channel. And that leads to bad decisions: scaling more on Mercado Libre because it "sells more," without realizing their own store leaves two or three times more margin per unit.
How much does it really cost you to sell on Mercado Libre?
Mercado Libre's fee isn't a single number. It's a stack of charges you have to add up one by one:
- Category selling fee: between 12% and 17% of the selling price depending on the category and listing type (Classic or Premium).
- Free shipping (Mercado Envíos): mandatory for Premium listings. An additional cost of 8% to 12% depending on weight and destination.
- Mercado Pago interest-free installments: if you offer installments, you absorb the financing cost. 3 interest-free installments cost you ~5%; 6 installments ~10%; 12 installments ~20%. For the full analysis, read about Mercado Pago fees.
- Mercado Ads: if you invest in Mercado Libre's in-platform ads to improve your ranking, add another 5-10% of the selling price.
- Mercado Libre Full: if you use Mercado Libre's fulfillment, there are additional storage and handling charges. We break down the details in the article on Mercado Libre Full.
Adding it all up — fee + shipping + installments + ads — the real cost of selling on Mercado Libre can reach 35-45% of the selling price. In a store with a 40% gross margin, that leaves almost no profit.
A real example: same product, two channels, very different margins
Product: sneakers. Selling price: $85,000. Product cost: $38,000.
Sold on Mercado Libre (Premium + Mercado Ads + 3 interest-free installments):
Mercado Libre fee: $14,450 (17%) + Shipping: $9,350 (11%) + 3x installments: $4,250 (5%) + Ads: $5,100 (6%) = $33,150 in charges. Profit: $85,000 − $38,000 − $33,150 = $13,850 — a 16% margin.
Sold in your own store (Tiendanube + Meta Ads + single payment):
Tiendanube fee: $850 (1%) + Mercado Pago single payment: $2,550 (3%) + Meta Ads CPA: $8,500 (10%) = $11,900 in charges. Profit: $85,000 − $38,000 − $11,900 = $35,100 — a 41% margin.
Same product. Your own channel leaves 2.5 times more profit per unit.
So why doesn't everyone sell mainly through their own store?
Because your own store has no traffic of its own. It needs ad spend to bring in visitors. And if you don't have a brand people search for directly, acquisition cost can be high.
The underlying issue is real ROAS. In Meta Ads, the ROAS the platform reports is overstated — it can be 30-50% higher than real ROAS because Meta takes credit for conversions that would have happened anyway. If you take Meta's ROAS at face value, you'll think your own store is more profitable than it really is. To understand the difference, read the article on real ROAS vs reported ROAS.
The real takeaway: Mercado Libre has guaranteed traffic but low margin. Your own store has high margin but requires building traffic. The winning strategy for most e-commerce businesses in Argentina is to use both channels strategically — not to pick one and abandon the other.
How should you split between Mercado Libre and your own store at each stage?
The ideal split depends on where you stand:
- New store (less than 6 months): start on Mercado Libre to validate the product and generate cash flow without spending on ads. But open your own store from month 1 to start building your base.
- Growing store (6-24 months): use Mercado Libre as your volume channel and run ads to your own store to build customers you own. Measure margin by channel, not volume.
- Mature store (more than 2 years): if you have a recognized brand, your own store should be your main channel. Mercado Libre becomes an acquisition channel for new customers you then move over to your store.
How Escalafy shows you real margin by channel
Running the Mercado Libre vs own store analysis in Excel takes hours and is always full of errors. Mercado Libre's fees change, shipping costs vary, and Meta's real ROAS is hard to calculate by hand.
Escalafy connects Tiendanube, Mercado Libre and Meta Ads and calculates real profit in real time by channel. You see at a glance how much each sale leaves you on Mercado Libre vs on Tiendanube, with every cost included: fees, shipping, ads, product cost. No Excel, no estimates.
For reference on the official fees for each category, you can check them directly in the Mercado Libre Argentina help center. Escalafy applies them automatically to every sale so you don't have to calculate them yourself.
Frequently asked questions about Mercado Libre vs your own store
Does Mercado Libre get me more sales than my own store?
Probably yes in volume, at least at first. Mercado Libre has massive organic traffic that a new store can't replicate without ad spend. But more sales doesn't mean more profit — if margin by channel is very different, you can bring in more revenue on Mercado Libre and make more profit in your own store.
Can I use the same price on both channels?
You can, but it doesn't make financial sense. On Mercado Libre you pay 25-40% in total charges; on Tiendanube you pay 10-15% (including ads). If you set the same price, your own store has a significantly higher margin. Many stores use slightly lower prices in their own store to nudge customers to buy there.
How do I calculate the real cost of my sales on Mercado Libre?
Add up: category fee + free shipping cost if you use a Premium listing + installment financing cost + Mercado Ads spend + packaging. Divide it by the selling price. That percentage is your real channel cost. In most categories it will land between 25% and 40%.
Is it possible to be profitable on Mercado Libre alone?
Yes, if you have a high product gross margin (over 50%) and you control shipping and ad costs. For most mid-priced categories — clothing, cosmetics, accessories — the gross margin isn't enough to absorb all of Mercado Libre's charges and leave real profit.
When does it make sense to scale back on Mercado Libre?
When most of your Mercado Libre customers are already repeat buyers and you could keep them in your own store with a loyalty program. Or when your Mercado Libre sales lose money and you only keep them for the volume. Exit gradually — not all at once — measuring the impact on your total customer base.
The question isn't "Mercado Libre or my own store?" but "how much does each channel leave me after every cost?" The real answer comes from margin per order by channel — not sales volume, not Meta's ROAS, not Tiendanube's stats. Escalafy calculates that number automatically so you make decisions based on real profit, not estimates.
