     Discount %  =  ($20 / $80) × 100  =  25% OFF

⚙️ THREE WAYS TO CALCULATE

🔵 MODE 1: FIND FINAL PRICE & SAVINGS

You see "$80 with 25% off." What do you actually pay?

 
ORIGINAL PRICE    $80.00
  ─────────────────────────▶
DISCOUNT %           25%
  ─────────────────────────▶
                    RESULT:
                    🏷️ You Save:    $20.00
                    💲 Final Price:  $60.00

🧠 Mental Math:
Final Price = Original × (1 - Discount%)


🟢 MODE 2: FIND DISCOUNT PERCENTAGE

You know the item was $80, now it's $60. What's the percentage off?

 
ORIGINAL PRICE    $80.00
  ─────────────────────────▶
FINAL PRICE       $60.00
  ─────────────────────────▶
                    RESULT:
                    🏷️ You Save:    $20.00
                    📊 Discount:     25%

🧠 Mental Math:
Discount% = (1 - (Final / Original)) × 100


🟡 MODE 3: REVERSE FROM FINAL PRICE

You paid $60 after a 25% discount. What was the original price?

 

FINAL PRICE       $60.00
  ─────────────────────────▶
DISCOUNT %           25%
  ─────────────────────────▶
                    RESULT:
                    🏷️ Original:   $80.00
                    📊 Savings:    $20.00

🧠 Mental Math:
Original = Final / (1 - Discount%)

🛑 WARNING: A 25% discount doesn't reverse with a 25% markup. To get back to $80 from $60, you need a 33.33% increase. Always run the numbers.


💀 WHY "20% OFF" CAN KILL YOUR BUSINESS

The Sales Bump Required to Keep the Same Total Profit

 
 
Your Profit Margin You Run a 20% Off Sale Unit Sales Increase Needed to Earn the Same Total Profit
10% 📈 +200% (3x the sales!)
20% 📈 +100% (Double your sales)
30% 📈 +67%
40% 📈 +50%
50% 📈 +40%

THE HARSH TRUTH: If your margin is thin, a discount forces you to sell dramatically more just to stand still. Use this table before hitting "Start Sale."


🛒 STACKED DISCOUNT TRAP

Why "Extra 20% Off Sale Items" Isn't What It Seems

You don't add:          20% + 20% = 40% off
The math is:
┌────────────────────────────────────────────────────┐
│                                                    │
│   $100  →  Minus 20%  =  $80                      │
│   $80   →  Minus 20%  =  $64                      │
│                                                    │
│   True Total Discount: 36% (NOT 40%)               │
└────────────────────────────────────────────────────┘

🧠 KEY INSIGHT: Stacked discounts are multiplicative, not additive. The second discount is always taken from the already-reduced price.


🛍️ THE PSYCHOLOGICAL PRICING TOOLKIT

 
 
Strategy How It Works Example Best Used For
% OFF Larger number looks bigger. 50% OFF! High-price items ($50+)
$ OFF Concrete savings feel tangible. $10 OFF! Low-price items (<$50)
BOGO Buy One Get One Free = 50% off, but moves 2 units. BOGO! Clearing excess inventory
Threshold Unlocks at a cart value. Save $15 on orders $75+ Increasing Average Order Value

THE RULE OF 100: If the price is under $100, advertise the percentage off. If it's over $100, advertise the dollar amount. "$50 off" feels stronger than "10% off" on a $500 item.


📈 THE DISCOUNT-FREE BUNDLE ALTERNATIVE

Before discounting, try this value-building formula that protects your margin.

The Bundle Formula:

┌───────────────────┐    ┌───────────────────┐    ┌───────────────────┐
│   PRODUCT A       │    │   PRODUCT B       │    │   "FREE" BONUS    │
│   (Hero Item)     │ +  │   (Complement)    │ +  │   (Low Cost to    │
│   Full Price      │    │   Added Value     │    │    You, High      │
│                   │    │                   │    │    Perceived Value)│
└───────────────────┘    └───────────────────┘    └───────────────────┘
                              │
                              ▼
┌───────────────────────────────────────────────────────────────────┐
│                    BUNDLE PRICE = $147                             │
│      (Vs. $178 if bought separately. You saved no margin,         │
│       you just shifted perceived value.)                          │
└───────────────────────────────────────────────────────────────────┘

Example:

  • Selling a $100 coffee maker (cost $40).

  • Add a $30 bag of premium beans (cost $5).

  • Add a $20 frother (cost $6).

  • Bundle Value: $150. **Your Cost:** $51. Sell at: $129.

  • Customer feels they saved $21. Your margin is still a healthy 60%.


✅ DISCOUNT PRE-FLIGHT CHECKLIST

Ask These 5 Questions Before Any Sale:

  • What is my current profit margin on this item? (Never discount a product with less than 30% margin without a clear liquidation goal.)

  • How many more units must I sell to break even? (Use the table in section 4.)

  • Is this discount conditioning my customers to wait? (If you run 40% off every month, your "sale" price is the real price.)

  • Have I tried a Bundle or Added-Value offer first?

  • Is the discount code easy to leak? (Influencer codes and coupon sites can make a "VIP" sale public instantly.)

Enjoy the little things in life. For one day, you may look back and realize they were the big things. Many of life's failures are people who did not realize how close they were to success when they gave up.
