Real profit on Mercado Livre: complete guide (2026)
Fees, full shipping, taxes and returns all factor into the math. See the full step-by-step to find the real margin on every SKU.
Calculating profit on Mercado Livre looks simple until you check the payout statement and notice less is left than expected. The reason is almost always the same: hidden costs that never make it into the pricing spreadsheet.
What goes into a SKU's cost
Before thinking about margin, list every cost that hits the sale:
- Product cost price
- Mercado Livre commission (varies by category)
- Shipping (classic or full)
- Fixed fee per sale
- Taxes (simplified regime or whichever applies)
- Estimated return cost
Commission and fixed fee
The commission is a percentage and depends on the category. The fixed fee is charged per completed sale — small, but significant on low-ticket items.
Practical example
For a R$ 100 product with a 17% commission and a R$ 0.50 fixed fee, you've already lost R$ 17.50 before any other cost.
Full vs. classic shipping
Full shipping carries storage and per-unit handling costs. Classic passes shipping on to the buyer but charges a dispatch fee. The most common blind spot is forgetting to pull inventory out of full once an item stops selling.
Taxes
Under Brazil's simplified tax regime, the effective rate climbs with revenue over the trailing 12 months. Use the effective rate, not the initial bracket.
Returns
Estimate a return rate per category. Every return creates reverse-shipping cost and, sometimes, a lost product.
Real profit only shows up once you look at the SKU after every deduction — not the gross payout.
Real margin
Real margin = (Net revenue − total cost) ÷ net revenue. If that number is under 12%, the product is probably bleeding cash without you noticing.
