Milewa Blog https://milewa.com.br/en/blog/ Practical articles for those selling on Mercado Livre and Shopee: how much you keep from each sale, how fees change the math, when Ads cause losses, and how to set prices without guessing. en Wed, 30 Sep 2026 14:02:04 GMT How much is really left when you sell R$ 100 on Mercado Livre https://milewa.com.br/en/blog/quanto-sobra-de-uma-venda-no-mercado-livre https://milewa.com.br/en/blog/quanto-sobra-de-uma-venda-no-mercado-livre Fri, 18 Sep 2026 15:00:00 GMT Margem e custos The full breakdown of a R$ 100 sale on Mercado Livre: commission, shipping cost, tax, packaging, and what actually goes into your pocket. With numbers from the official shipping cost table checked in September 2026. The three price steps where Shopee makes you earn less by selling for more https://milewa.com.br/en/blog/faixas-de-preco-shopee-ganhar-menos-vendendo-mais-caro https://milewa.com.br/en/blog/faixas-de-preco-shopee-ganhar-menos-vendendo-mais-caro Fri, 18 Sep 2026 15:00:00 GMT Shopee On Shopee, raising the price from R$ 79.99 to R$ 80.00 takes R$ 6.69 out of your pocket. There are three steps like this in the commission table, and I show where each dead zone starts and ends. Free shipping on Mercado Livre: who pays and why the R$ 79 step is worse for heavy sellers https://milewa.com.br/en/blog/frete-gratis-mercado-livre-quem-paga https://milewa.com.br/en/blog/frete-gratis-mercado-livre-quem-paga Fri, 18 Sep 2026 15:00:00 GMT Mercado Livre From R$ 79, the shipping cost jumps to a new tier that depends on the package weight. For a 10 kg item, it only pays off again above R$ 125. See the step table by weight. Good ACOS, bad profit: the number of listings your store should watch https://milewa.com.br/en/blog/acos-bom-lucro-ruim-tacos https://milewa.com.br/en/blog/acos-bom-lucro-ruim-tacos Fri, 18 Sep 2026 15:00:00 GMT Anúncios pagos ACOS compares ad spend to revenue, not to margin. For a product with 12% margin, an ACOS of 15% is already a loss. See how to calculate the maximum TACOS your store can handle. Mercado Livre Full: the working capital math that decides if it’s worth it https://milewa.com.br/en/blog/full-mercado-livre-quando-compensa https://milewa.com.br/en/blog/full-mercado-livre-quando-compensa Fri, 18 Sep 2026 15:00:00 GMT Mercado Livre Full charges storage per day and per idle unit. Before sending stock, calculate the SKU’s coverage days. Over 90 days, Mercado Livre’s warehouse becomes your biggest hidden cost. The cost mistake that makes your margin look ten points better than it is https://milewa.com.br/en/blog/custo-medio-cmv-erro-que-infla-a-margem https://milewa.com.br/en/blog/custo-medio-cmv-erro-que-infla-a-margem Fri, 18 Sep 2026 15:00:00 GMT Margem e custos Using the price from the first purchase or the last one to calculate margin distorts the result. See the difference between first purchase cost, weighted average cost, and replacement cost, and when to use each one. Returns: why 4% of orders returned costs you 6% of your profit https://milewa.com.br/en/blog/devolucoes-quanto-comem-do-lucro https://milewa.com.br/en/blog/devolucoes-quanto-comem-do-lucro Fri, 18 Sep 2026 15:00:00 GMT Margem e custos The marketplace refunds commission and shipping on returns, but the sale disappears and the return has a cost. See the real calculation and why partial refunds are usually the cheapest way out. ABC curve: your store’s best seller is probably only fifth in profit https://milewa.com.br/en/blog/curva-abc-os-skus-que-pagam-a-loja https://milewa.com.br/en/blog/curva-abc-os-skus-que-pagam-a-loja Fri, 18 Sep 2026 15:00:00 GMT Gestão da loja ABC curve by revenue shows who sells. By margin, it shows who pays the bills. The names rarely match on both lists, and the difference is where the decisions are. Catalog and featured seller: how to fight for position without burning your margin https://milewa.com.br/en/blog/catalogo-buy-box-sem-queimar-margem https://milewa.com.br/en/blog/catalogo-buy-box-sem-queimar-margem Fri, 18 Sep 2026 15:00:00 GMT Mercado Livre Winning the catalog listing isn’t about being the cheapest. And if you’re going to lower your price, drop it past the R$ 79 step: going from R$ 80 to R$ 78.99 actually increases your margin instead of reducing it. Reputation isn’t vanity: it shows up in your cost spreadsheet https://milewa.com.br/en/blog/reputacao-o-que-derruba-de-verdade https://milewa.com.br/en/blog/reputacao-o-que-derruba-de-verdade Fri, 18 Sep 2026 15:00:00 GMT Gestão da loja Losing green reputation on Mercado Livre makes shipping more expensive for all listings above R$ 79 at once. See what counts in the calculation, what doesn’t, and which metric to watch every week. Promotion on Mercado Livre: the cost-sharing almost no one checks https://milewa.com.br/en/blog/promocoes-mercado-livre-coparticipacao https://milewa.com.br/en/blog/promocoes-mercado-livre-coparticipacao Fri, 18 Sep 2026 15:00:00 GMT Mercado Livre In cost-sharing campaigns, Mercado Livre covers part of the discount, and the promotional sale can pay more than the full-price sale. The problem is the refund doesn’t always show up in your statement. Ideal price: start with the margin you want, not the competitor https://milewa.com.br/en/blog/preco-ideal-comece-pela-margem https://milewa.com.br/en/blog/preco-ideal-comece-pela-margem Fri, 18 Sep 2026 15:00:00 GMT Margem e custos Commission and tax are percentages of the price, so adding them to the cost is wrong. The right formula divides, not adds. And in marketplaces, there’s usually more than one price that gives you the same margin. Shopee: why the money you get is more misleading than on Mercado Livre https://milewa.com.br/en/blog/shopee-repasse-o-que-cai-na-conta https://milewa.com.br/en/blog/shopee-repasse-o-que-cai-na-conta Fri, 18 Sep 2026 15:00:00 GMT Shopee Shopee pays you the net amount, with fees already deducted before you see it. This changes how you check your margin and hides mistakes that would be obvious on Mercado Livre. The tax that rises on its own: why your margin shrinks as your store grows https://milewa.com.br/en/blog/imposto-simples-nacional-margem-marketplace https://milewa.com.br/en/blog/imposto-simples-nacional-margem-marketplace Fri, 18 Sep 2026 15:00:00 GMT Margem e custos Under Simples Nacional, the effective tax rate follows your revenue from the last 12 months. Growing from R$ 500,000 to R$ 2 million cuts more than 3 margin points from all products, with no change in price or cost.
