What Does a 30% Discount Mean?
A 30% discount means the price of a product or service is reduced by 30% from its original price. In other words, the buyer pays 70% of the original price.
For example:
- Original price = $100
- Discount = 30% of 100 = $30
- Sale price = $100 – $30 = $70
This discount effectively saves the buyer $30.
How to Calculate a 30% Discount: Step-by-Step
You can calculate the discounted price easily by following these steps:
Step 1: Convert Percentage to a Decimal
30% = 30 ÷ 100 = 0.30
Step 2: Calculate Discount Amount
Discount amount = Original Price × 0.30
Step 3: Calculate Final Price
Final Price = Original Price − Discount amount
= Original Price × (1 − 0.30)
= Original Price × 0.70
Example Calculation
| Item | Original Price | Discount Amount (30%) | Final Price (70%) |
|---|---|---|---|
| Jacket | $150 | 150 × 0.30 = $45 | 150 − 45 = $105 |
| TV | $700 | 700 × 0.30 = $210 | 700 − 210 = $490 |
| Sneakers | $120 | 120 × 0.30 = $36 | 120 − 36 = $84 |
Calculating 30% Off in Your Head or With a Calculator
To mentally estimate 30% off, you can first find 10% of the price and multiply it by 3:
- 10% of $200 is $20
- 30% is $20 × 3 = $60
- Final price = $200 − $60 = $140
For calculator use:
- Type original price
- Multiply by 0.30
- Subtract result from original price

When Discounts Stack: Understanding Multi-Step Discounts
A single 30% discount is easy to calculate, but sometimes promotions apply multiple discounts sequentially — for example, 30% off, then an extra 15% off the reduced price. Crucially, these stack by multiplication, not simple addition.
Example: 30% off then 15% off
- For $100:
- After 30% off: $100 × 0.70 = $70
- Then 15% off: $70 × 0.85 = $59.50
- Effective discount = $100 − $59.50 = $40.50 or 40.5%, not 45%
Psychological Impact of 30% Discounts on Consumer Behavior
- Significance: A 30% discount feels substantial, motivating buyers to act quickly.
- Value perception: It’s enough to feel like a deal without a brand feeling “cheap.”
- Impulse purchases: Encourages consumers to try new items or add extras to carts.
- Satisfaction: Customers value the tangible, visible saving over vague percentages above or below 30%.
