Bulk Discount Calculator: Save Money on Wholesale Orders
Understanding Bulk Discount Tiers
Most stores offer tiered bulk discounts:
| Quantity | Discount |
|---|---|
| 1-5 units | No discount |
| 6-10 units | 10% off |
| 11-20 units | 15% off |
| 21-50 units | 20% off |
| 50+ units | 25% off |
The more you buy, the higher the discount.
The Bulk Discount Formula
Total Cost = (Unit Price × Quantity) × (1 - Discount%) Per-Unit Cost = Total Cost ÷ Quantity
Real Bulk Discount Examples
Example 1: Office Supplies
Pens normally: $1.00 each
| Quantity | Discount | Total Cost | Per-Unit Cost | vs. Regular |
|---|---|---|---|---|
| 5 | 0% | $5.00 | $1.00 | - |
| 10 | 10% | $9.00 | $0.90 | Save $1.00 |
| 25 | 15% | $21.25 | $0.85 | Save $3.75 |
| 50 | 20% | $40.00 | $0.80 | Save $10.00 |
Buying 50 pens saves you $10 (20% total savings).
Example 2: Coffee Beans
Coffee normally: $15.00 per pound
| Quantity | Discount | Total | Per-Pound Cost | Savings |
|---|---|---|---|---|
| 1 lb | 0% | $15.00 | $15.00 | - |
| 5 lbs | 5% | $71.25 | $14.25 | $3.75 |
| 10 lbs | 10% | $135.00 | $13.50 | $15.00 |
| 25 lbs | 15% | $318.75 | $12.75 | $56.25 |
Buying 25 lbs saves $56.25 compared to single-pound purchases.
Example 3: The Deceptive Bulk Deal
T-shirts normally: $20.00 each
Bulk offer: "Buy 50 t-shirts at 25% off!"
❌ Wrong thinking: "I save $250!"
- 50 × $20 = $1,000
- 25% off = $250 savings
✅ Reality check:
- Total cost: 50 × $20 × 0.75 = $750
- Per-shirt cost: $750 ÷ 50 = $15 each
- But: Do you need 50 t-shirts?
- If you'd normally buy 10: You're paying $150 more than needed
- Bulk "savings" = -$150 (you lose money!)
When Bulk Discounts Actually Save Money
Scenario 1: Essential Items You Use Regularly
- Office supplies (pens, paper, folders)

- Dry pasta
- Spices
- Non-perishables
Action: Buy in bulk ✓
Scenario 3: Items You Share with Others

When Bulk Discounts DON'T Save Money
Scenario 1: Items That Spoil
- Fresh produce (expires quickly)
- Dairy products
- Meat
Action: Don't bulk buy ✗
Scenario 2: Items You Rarely Use
- Specialty ingredients
- Seasonal items
- Trendy products
Action: Don't bulk buy ✗
Scenario 3: Items Taking Storage Space
- Bulky items
- Limited storage
- Items you can't use before expiration
Action: Don't bulk buy ✗
The True Cost: Storage & Waste
Bulk buying has hidden costs:
- Storage space: Where do 50 items go?
- Spoilage: Some items expire before use
- Capital: Money tied up in inventory
- Opportunity cost: Money not invested elsewhere
Real formula:
True Savings = Discount Savings - (Storage + Spoilage + Interest)
Tools for Bulk Calculations

- Discount Calculator - Find final bulk price
- What Percent is A of B - Compare unit prices
The Bottom Line
Bulk discounts save money ONLY on items you actually need and use before expiration. Calculate your per-unit cost, compare to regular purchases, account for storage and spoilage, then decide.
Smart buying beats bulk buying.
