Black Friday Discount Strategy:
How Much to Offer Without Losing Margin

A good Black Friday discount strategy starts with contribution margin, not with what competitors offer. Work out how many extra orders each offer needs to match your full-price profit, then pick the smallest offer that moves your customers. For many D2C brands that means 15% to 25% off, a spend tier, or a free gift, rather than 40% sitewide.

The data from last year supports going shallower. Across Klaviyo brands, discounts fell 10% YoY over BFCM 2025, and brands with the smallest discounts grew 14%, the fastest of any group. The same release says daily average discounts never went above 30%. This post covers the margin math, the main offer types, and how to match each offer to a customer segment. It sits inside our full BFCM 2026 playbook.

How much should you discount on Black Friday?

Enough to beat a shopper's default of "I will buy it later," and no more. The ceiling is set by your margin. The floor is set by your customers.

Three inputs decide the number:

• Contribution margin per order at full price. Price minus product cost, shipping and fulfillment, and payment fees. Our contribution margin guide shows how to calculate it.
• How price sensitive your buyers are. Look at past promotions. If a 15% code moved as many units as a 25% code, go with 15%.
• What else you can give. Free shipping, a gift, or a bundle often feels bigger to the customer than it costs you.

Klaviyo's 2025 report flags one exception: Home and Garden needed deeper markdowns than other categories. If you sell furniture or decor, expect to sit nearer the top of the range. For beauty, apparel and supplements, a smaller headline number with a strong reason to buy now usually holds up better than a deep cut.

How do different Black Friday offers affect your margin?

Here is the math for a fictional skincare brand. The serum sells for $80. Product cost is $20, shipping and fulfillment cost $9, and we assume payment fees of 3% of the price paid. Ad spend is left out so the offers compare cleanly.

Read the last column carefully. At 40% off, this brand must almost triple its order count to make the same profit it would have made at full price. At 20% off it needs roughly half again as many orders. A gift with a $25 perceived value costs it just 14% more orders.

The formula is simple: full-price contribution divided by discounted contribution, minus one. Run it with your own costs before you announce anything.

Sitewide, tiered or free gift: which Black Friday offer works best?

Each offer type does a different job. Pick by the problem you want to solve.

Tiers work best when the first tier sits just above your current average order value. Shopify reported an average cart of $114.70 across its merchants over BFCM 2025, but your own AOV is the number that matters. If yours is $70, a first tier at $100 asks for one more item.

A gift protects your price. A customer who paid $80 and got a free mini still thinks your serum costs $80 in January. Our bundle strategy guide and free shipping strategy post go deeper on those two levers.

The build for each one is in our Shopify Black Friday discount setup guide.

Should you give every customer the same Black Friday discount?

No. One offer for everyone hands your best customers a discount they did not need and gives cold browsers too little reason to act.

A segmented approach, using the six segments in our Klaviyo BFCM segments guide:

• VIPs and past BFCM buyers. Early access on Tue Nov 24 at the public offer, or a gift on top. Access is the reward, so the discount can stay the same.
• Engaged subscribers who have not bought. The public offer from Fri Nov 27, plus proof: reviews, bestsellers, return policy.
• Recent full-price buyers. A gift-with-purchase version instead of a price cut, so nobody feels they overpaid on Nov 16.
• Subscription customers. A discount on add-ons or a prepaid plan, not on the product they already buy every month.

Klaviyo also reported that revenue from repeat customers rose 13.5% YoY over BFCM 2025. Your existing buyers are a large share of the weekend. They rarely need your deepest offer to come back.

How should your Black Friday offer change from Black Friday to Cyber Monday?

Keep the core offer stable and change the angle. If your discount gets deeper every day, your list learns to wait.

A structure that fits the 2026 calendar:

Cyber Monday deserves a hook because it still grows. Klaviyo reported Cyber Monday up 11% YoY in 2025, with Black Friday up 10%. Adding a gift tier on Monday gives people a new reason to buy without cutting price again.

Be careful with "extended" sales. Say it once, then end it when you say you will. A sale that never ends trains customers to ignore your deadlines next year.

How do you avoid fake discounts on Black Friday?

Use a real former price. The FTC's Guides Against Deceptive Pricing say a former price comparison should use the actual, bona fide price the item was offered at, on a regular basis, for a reasonably substantial period. Raising prices in October so a November markdown looks bigger is the textbook example of a fictitious price.

Three practical rules:

1. Lock prices now. Do not change regular prices in the six weeks before the sale.
2. Set compare-at prices to the price you actually charged. Not the MSRP you never used.
3. Keep your math simple. "25% off everything" is easier to defend and easier to understand than stacked codes.

Honest pricing also protects January. If your post-BFCM price is the same as your pre-BFCM price, customers trust your full-price weeks. See our D2C pricing strategy post for how to set those regular prices in the first place.

How do you put your Black Friday discount strategy into action?

Write the plan on one page before you build anything. It should answer five questions:

1. What is the public offer, in one sentence?
2. What does each segment get, and when?
3. What is the full-price contribution per order, and how many extra orders does the offer need?
4. Which Shopify discounts, codes and combinations make it work?
5. When does it end, to the minute, in your store's time zone?

Then build it on the store and the landing page. Our Shopify Black Friday landing page guide covers how to present the offer above the fold. After the weekend, compare results with BFCM email benchmarks from 2025 and your own last year.
