BOGO vs Percentage Discount: Which Is Better for Your Store?
BOGO and percentage discounts look similar to customers—but they hit your margins differently. Learn the real math, psychology, and a decision framework to pick the right one.
By Muhammed Tüfekyapan
Key Takeaways
- 50% off and BOGO have identical per-unit economics ($50 effective price)—but BOGO moves 2 units while percentage moves 1
- BOGO triggers emotion ('FREE!') while percentage triggers logic ('I'm saving X')—know which works for your audience
- At margins under 40%, both discount types can destroy profitability—calculate before launching any promotion
- The dedicated buyer problem: Broadcasting discounts wastes margin on customers who would have bought anyway
- Targeting matters more than discount type—a well-timed percentage beats a broadcast BOGO every time
- When in doubt, percentage is more flexible—it can be triggered at precise moments for specific visitors
50% off. Or Buy One Get One Free. To customers, these sound similar. To your profit margins, they're completely different. You're trying to decide between BOGO vs percentage discount. Which one should you use?
Here's the truth: Both discount types can work. Both can also destroy your margins. The right choice depends on your specific goal, your product price, and who you're targeting.
This guide gives you the full picture. We'll compare buy one get one vs 50% off with real math. We'll show you the psychology behind each. And we'll help you pick the right one for your store.
What This Guide Covers:
- How percentage discounts and BOGO actually work
- The real math behind both (not just the obvious stuff)
- When each discount type works best
- The hidden costs most guides don't mention
- A clear decision framework for your store
This isn't about which discount is "better." It's about which is better for YOUR situation. Let's dive in.
Understanding Both Discount Types
Before we compare, let's make sure we're on the same page. What exactly are we talking about?
What Is a Percentage Discount?
A percentage discount is a direct price reduction. You take a percentage off the original price. Simple.
- 10% off, 20% off, 50% discount—you know the drill
- Customer pays the reduced price
- They get the same quantity they would normally buy
Example: A $100 product at 50% off = Customer pays $50, gets 1 item.
In Shopify, you can set this up as a discount code or automatic discount. Works on single products, collections, or the whole store.
What Is BOGO?
BOGO means Buy One Get One. The customer buys products and receives additional products free or discounted.
- Buy one get one free = Buy 1, get 1 free
- Buy 2 Get 1 Free = Buy 2, get 1 free
- Buy X Get Y at % Off = Buy something, get something else discounted
Example: A $100 product with BOGO = Customer pays $100, gets 2 items.
In Shopify, you set this up using the "Buy X Get Y" discount type. Customer needs to add multiple items to trigger it.
The Basic Math Comparison
Let's see how these compare side by side. We'll use a $100 product as an example.
| Factor | 50% Off Discount | BOGO (Buy 1 Get 1 Free) |
|---|---|---|
| Customer Pays | $50 | $100 |
| Customer Receives | 1 item | 2 items |
| Effective Price Per Unit | $50 | $50 |
| Your Revenue | $50 | $100 |
| Your Cost (COGS at $30) | $30 | $60 |
| Your Profit | $20 | $40 |
Key Insight:
The effective price per unit is the same ($50). But BOGO generates more total revenue and profit because it moves 2 units instead of 1. This is the basic math. But there's more to the story.
When Each Discount Type Works Best
Now let's get strategic. BOGO or percentage off which is better depends on your situation.
When Percentage Discounts Work Best
High-Value Products (Over $100)
For expensive items, percentage discounts often work better. Why? The Rule of 100.
- Under $100: "50% off" sounds bigger than "$25 off"
- Over $100: "$75 off" sounds bigger than "25% off"
For a $200 product, "Save $50" feels more concrete than "25% off." Customers don't want to do math.
Single-Item Purchases
Some products are naturally bought one at a time. Think:
- Fashion items (one dress, one jacket)
- Electronics (one phone, one laptop)
- Furniture (one sofa, one table)
Forcing BOGO on these feels unnatural. "Buy one sofa, get one free" doesn't make sense. But "30% off" does.
New Customer Acquisition
Percentage discounts work great for first-time buyers:
- "15% off your first order" is clear and simple
- "Subscribe and get 10% off" captures emails
- Easy to set as single-use, targeted offers
When BOGO Works Best
Consumables and Replenishment Products
BOGO promotions shine for products customers use up and reorder:
- Beauty and skincare products
- Supplements and vitamins
- Food and beverages
- Cleaning supplies
The customer was going to buy again anyway. BOGO just accelerates the next purchase.
Low-Ticket, High-Margin Items
For products under $30-40 with strong margins:
- "FREE" feels more valuable than "50% off" on cheap items
- Accessories, basics, small add-ons work well
- The word "free" triggers a stronger emotional response
Inventory Clearance (When Units Matter)
If your goal is moving physical units—not maximizing profit per order:
- Seasonal items need to go before next season
- Discontinued products sitting in warehouse
- Storage costs exceed the value of holding
BOGO moves twice as many units. That's valuable when inventory is the problem.
Industry Patterns
| Industry | Preferred Type | Why |
|---|---|---|
| Fashion/Apparel | Percentage (seasonal), BOGO (basics) | Seasonal clearance vs. wardrobe building |
| Beauty/Cosmetics | BOGO (samples, travel sizes) | Trial generation, product discovery |
| Electronics | Percentage | High price points, single-item focus |
| Home Goods | BOGO (collections) | Complete-the-look, matching items |
| Food/Beverage | BOGO | Consumable, repeat purchase nature |
The Hidden Differences (What Most Guides Miss)
Now for the important stuff. The differences that actually matter for your bottom line.
The Psychological Difference
BOGO and percentage discount trigger different parts of the brain.
How Customers See BOGO:
- "I'm getting something FREE!" → Excitement, dopamine hit
- Feels like a reward, not a discount
- 66% of shoppers prefer BOGO over other promotions
How Customers See Percentage Off:
- "I'm saving money" → Rational calculation
- Feels like a smart purchase decision
- Easier to understand exact savings
Key Insight:
BOGO triggers emotion (free stuff!). Percentage triggers logic (I'm saving X). Different customers respond to different triggers. Know your audience.
The Margin Reality Check
Let's look at margins more carefully. This is where BOGO vs percentage discount gets real.
Scenario: Product costs $30 to make, sells for $60 (50% margin)
With 50% Off:
- Customer pays $30, gets 1 item
- Your cost: $30
- Your profit: $0 (break-even)
With BOGO:
- Customer pays $60, gets 2 items
- Your cost: $60 (2 × $30)
- Your profit: $0 (break-even)
Wait—both result in zero profit at 50% margin? Yes. But BOGO moved 2 units while percentage moved 1.
Now with higher margins: Product costs $20 to make, sells for $60 (67% margin)
With 50% Off:
- Revenue: $30 | Cost: $20 | Profit: $10
With BOGO:
- Revenue: $60 | Cost: $40 | Profit: $20
With healthy margins, BOGO generates more total profit AND moves more inventory. But it also gives away more free product.
The Dedicated Buyer Problem
Here's something most guides never mention. Both BOGO and percentage discounts share the same flaw.
The problem: You're giving discounts to customers who would have bought anyway.
"Dedicated buyers" don't need incentives. They've already decided to buy. But if you broadcast your discount to everyone, dedicated buyers get discounts too.
BOGO makes this worse:
- BOGO forces customers to take 2 items
- A dedicated buyer who wanted 1 item now gets 1 free
- You've doubled your giveaway to someone who didn't need convincing
Percentage can be more targeted:
- Percentage discounts can be applied selectively
- Show them only to hesitant visitors
- Protect dedicated buyers from unnecessary discounts
Expert Opinion:
The discount type matters less than WHEN and TO WHOM you show it. A 50% discount shown at the right moment to a hesitant visitor beats a BOGO broadcast to everyone—including people who were buying anyway.
The Rule of 100: Why the Bigger Number Always Wins
Customers don't calculate—they compare. Under $100, use percentages. Over $100, use dollar amounts. Master Jonah Berger's framework and frame every discount for maximum impact.
The Decision Framework
So, is BOGO better than percentage discount? Use this framework to decide.
Quick Decision Matrix
| Your Situation | Choose BOGO | Choose Percentage |
|---|---|---|
| Product price under $50 | ✓ | — |
| Product price over $100 | — | ✓ |
| Customer naturally buys 1 item | — | ✓ |
| Customer naturally buys 2+ items | ✓ | — |
| Goal: Move units fast | ✓ | — |
| Goal: Maximize profit per order | — | ✓ |
| Consumable/replenishment product | ✓ | — |
| One-time purchase product | — | ✓ |
| High margin (60%+) | ✓ | Either works |
| Low margin (under 40%) | Be careful | Test carefully |
The Questions to Ask Yourself
Before choosing between BOGO vs percent off Shopify, ask these questions:
1. "Does my customer naturally want 2+ of this product?"
- Yes → BOGO can work well
- No → Percentage is simpler and makes more sense
2. "What's my goal—units or profit?"
- Units (inventory clearance) → BOGO moves more
- Profit (sustainable growth) → Percentage is more flexible
3. "What's my margin situation?"
- High margin (60%+) → Either works, BOGO moves more
- Medium margin (40-60%) → Test both carefully
- Low margin (under 40%) → Be very careful with BOGO
4. "Am I targeting or broadcasting?"
- Broadcasting to everyone → Both are risky
- Targeting hesitant visitors → Percentage is more flexible
The Smarter Approach: Targeting Over Discount Type
Here's the real insight. The choice between percentage discount vs buy one get one free is actually the wrong question.
The right question is: "WHO am I showing this discount to?"
Why Targeting Matters More
- Wrong approach: Broadcast BOGO or percentage to everyone
- Right approach: Show offers only to visitors who need a nudge
When you broadcast discounts to everyone:
- Dedicated buyers get free discounts (margin waste)
- Customers learn to wait for promotions
- You become a "sale brand" even if you don't want to be
When you target discounts by intent:
- Dedicated buyers pay full price (margin protected)
- Hesitant visitors get the push they need
- You convert more without training discount dependency
How This Changes the BOGO vs Percentage Decision
BOGO is harder to target:
- Customer needs 2 items in cart to trigger
- Usually applied automatically to everyone
- Hard to show to specific visitors at specific moments
Percentage is more flexible:
- Can be triggered at precise moments (exit intent, time on page)
- Can be personalized to specific visitors
- Can be time-limited with genuine urgency
The Growth Suite Approach:

Setting Up Each Discount Type in Shopify
Quick reference for setting up both discount types.
Percentage Discount Setup
- Go to Shopify Admin → Discounts
- Click "Create discount"
- Choose "Amount off products" or "Amount off order"
- Select "Percentage"
- Set your percentage amount
- Choose eligibility (all products, specific collections, etc.)
- Set usage limits and dates
- Save
BOGO Setup
- Go to Shopify Admin → Discounts
- Click "Create discount"
- Choose "Buy X Get Y"
- Configure qualifying products (what customer must buy)
- Set minimum quantity
- Configure reward (free or discounted)
- Set usage limits and dates
- Save
What to Measure for Both
- Conversion rate change: Did more people buy?
- Average order value: Did order sizes change?
- Profit per order: Not just revenue—actual profit
- Post-promotion behavior: Do customers return at full price?
Key Takeaways
Summary: BOGO vs Percentage Discount
- Same effective discount, different mechanics — 50% off and BOGO can have identical per-unit economics. But BOGO moves more inventory while percentage preserves flexibility.
- BOGO triggers emotion, percentage triggers logic — "FREE" is powerful, but only if customers naturally want multiple items.
- The Rule of 100 applies to percentage, not BOGO — For high-ticket items, show dollar savings. BOGO's "FREE" works at any price but requires multi-item purchase.
- Margin matters more than discount type — At low margins (under 40%), both BOGO and percentage can destroy profitability. Calculate before launching.
- Targeting beats discount type — The biggest difference isn't BOGO vs. percentage. It's broadcast vs. intent-based. Showing any discount to dedicated buyers is wasted margin.
- When in doubt, percentage is more flexible — Percentage discounts can be applied with surgical precision. BOGO is a blunter instrument.
The Bottom Line
Don't ask "BOGO vs percentage discount—which is better?"
Ask: "What's my goal, who's my target, and what's my margin?"
The answers will make the choice obvious.
Final Thought
BOGO and percentage discounts are both tools. A hammer isn't better than a screwdriver—it depends what you're building.
For inventory clearance with healthy margins, BOGO can work great. For targeted conversion optimization with margin protection, percentage discounts—delivered at the right moment to the right visitor—are often smarter.
But the smartest approach? Stop broadcasting discounts to everyone. Start showing them only to visitors who actually need a nudge.
