Black Friday pricing without destroying the year’s margin

A Black Friday discount preserving margin comes from each product’s calculation rather than a round number. Calculate margin, decide how much to give up, limit quantity, and measure results afterward. A 50%-off-everything discount copied from large chains works for businesses with scale and suppliers funding the promotion. For small businesses, it usually becomes the month of selling more and earning less.
October still leaves time to negotiate with suppliers, build bundles, and adjust stock to the offer. In November, pricing becomes a panicked decision.
How do you calculate the maximum discount per product?

First, margin: price minus direct cost, payment fee, tax, shipping you pay, and a share of fixed costs. Profit margin shows the calculation. Second, the minimum profit per unit you accept during the campaign. It is not zero: campaign orders require more service work and exchanges than normal orders.
The maximum discount is margin minus that minimum profit. If margin is 40% and you want to retain 15%, the maximum discount is 25%. Round down, never up. Remember card fees apply to the discounted price, but fixed cost per order does not change: packing a R$ 75 order costs the same as packing a R$ 100 order.
| Product margin | Desired minimum profit | Maximum discount |
|---|---|---|
| 50% or more | 20% | 30% |
| 40% to 49% | 15% | 25% |
| 30% to 39% | 10% | 20% |
| 25% to 29% | 10% | 15% |
| Below 25% | 10% | No discount: bundle or shipping |
Below 25% margin, the remaining discount is below 15%: it draws little attention and disappears into extra campaign service and exchange costs. Bundles or shipping work better in that range.
What offer works when margin does not allow a discount?
A bundle. Combine a high-margin product with a low-margin one and discount the set. Customers see “buy two and pay less”; your average margin holds. Combos and bundles shows how to create them.
Free shipping above an amount calculated so average orders cover shipping. A low-cost, high-perceived-value gift such as a sample or accessory. Pix-only discounts, because Pix has no fee and arrives immediately, so 5% off with Pix costs less than 5% off on card installments. Payment terms, such as more interest-free installments when the intermediary allows them without charging you.
How do you limit losses if the offer succeeds more than expected?
Limit quantity per product: when it runs out, it runs out, and the store must hide the product automatically. Limit units per customer so discounts do not become resale opportunities. Use a short, visible deadline: “until November 27 or while stocks last.”
An example. A pet store has pet food with a 22% margin. It cannot support a discount. It bundles the R$ 80 food, a R$ 40 treat with 60% margin, and a R$ 40 toy with 55% margin, then discounts the R$ 160 bundle by 15%. The bundle sells for R$ 136, profit stays near R$ 40, and bundle margin around 30%. Average order value increases, and the food attracting the customer joins the campaign without losing money.
Record today’s actual price for every offer product. It proves November’s discount is real; reference prices explains why this prevents fines.
What to do now
Build a spreadsheet with product, cost, margin, minimum profit, and maximum discount. Decide the offer from it rather than a competitor’s announcement. If you do not have these numbers separated, the problem precedes the discount.

Frequently asked questions
What discount should I offer on Black Friday?
What the product margin permits, minus the minimum profit you want to keep. For most small-store products, this is 15% to 30%. Beyond that, only with quantity limits and an inventory-clearance objective.
Is selling at a loss on Black Friday worthwhile to acquire customers?
Only with a measured repeat-purchase plan: customer records, a post-purchase message, and a good-margin product to offer in December. Without it, it is loss without return.
Are Pix discounts permitted?
Yes. Since 2017, the law allows different prices by payment method if disclosed before purchase.
