How to Calculate 30% Discount - 3 Easy Methods
🧮Method 1: Quick Mental Math (No Calculator Needed)
Perfect for in-store shopping when you want quick estimates.
- 1Find 10% by moving decimal left
$100.00 → $10.00 (this is 10%) - 2Multiply by 3 to get 30%
$10.00 × 3 = $30.00 (this is 30%) - 3Subtract from original price
$100.00 - $30.00 = $70.00 ✅
Real Example - MacBook Air:
- • Original: $1,000
- • 10% = $100
- • 30% = $100 × 3 = $300
- • Pay: $1,000 - $300 = $700 ✅
📱Method 2: Multiply by 0.70 (Fastest for Calculator)
If you have a calculator or phone, this is the quickest method.
Formula: Final Price = Original Price × 0.70
Why 0.70? Because 100% - 30% = 70% = 0.70. You're paying 70% of the original price.
Examples:
- • $100 × 0.70 = $70
- • $500 × 0.70 = $350
- • $1,000 × 0.70 = $700
💡 Pro Tip:
For any discount, subtract the percentage from 100 and convert to decimal:
- • 20% off → × 0.80
- • 25% off → × 0.75
- • 30% off → × 0.70
- • 40% off → × 0.60
📐Method 3: The Complete Formula
Discount Amount = Original Price × (Discount % ÷ 100)
Step-by-step:
Original Price: $100
Discount %: 30
Discount Amount = $100 × (30 ÷ 100)
Discount Amount = $100 × 0.30
Discount Amount = $30
Final Price = $100 - $30 = $70
Or directly calculate final price:
Final Price = Original Price × (1 - Discount %)
Final Price = $100 × (1 - 0.30)
Final Price = $100 × 0.70
Final Price = $70
💡 Which Method Should You Use?
| Situation | Best Method | Why |
|---|---|---|
| In-store shopping | Method 1 (Mental Math) | Quick estimates without phone |
| Online shopping | Method 2 (×0.70) | Fastest with calculator |
| Exact calculations | Method 3 (Formula) | Most accurate, shows full math |
| Large purchases | Method 2 or 3 | Avoid mental math errors |

Frequently Asked Questions
How do you calculate 30% off?
To calculate 30% off: multiply the price by 0.30 to get the discount amount, then subtract it from the original price. For example: $500 × 0.30 = $150 discount, so you pay $350.
How do I calculate 30% discount without a calculator?
Use the "times 3" method: Find 10% by moving the decimal left, then multiply by 3. For $100: 10% = $10, so 30% = $10 × 3 = $30 discount. Pay $70.
Is 30% off better than Buy One Get One Free (BOGO)?
Yes! 30% off one item ($70 on $100) is better than BOGO (two items for $200 = $100 each). However, BOGO is better if you need two items and would buy them anyway.
How much is 30% off $500?
30% off $500 = $150 discount. You pay $350. Quick math: $500 × 0.70 = $350 or (10% = $50, so 30% = $150).
What's the quickest way to calculate 30% discount in a store?
Move the decimal left to find 10% ($100 → $10), then multiply by 3 ($10 × 3 = $30). Subtract from price: $100 - $30 = $70. Takes 5 seconds!
When do Black Friday sales typically offer 30% off?
30% off is common during Black Friday (Nov 29, 2025), electronics, clothing, and home goods. Cyber Monday online retailers match Black Friday deals. Also expect 30% off during Memorial Day, July 4th, and Labor Day weekends.
Can I stack 30% off with other discounts?
Usually no—most retailers don't allow discount stacking. However, some allow 30% off sale price (already reduced items), store credit card additional 5-10% (check terms), or cashback rewards (separate from store discount). Pro tip: Ask at checkout if combining is allowed—policies vary by store.
How do I verify a store's "30% off" claim is real?
1. Check original price online before sale (Google Shopping, CamelCamelCamel for Amazon). 2. Calculate expected price: Original × 0.70. 3. Compare to sale price shown. 4. Be wary if "original price" seems inflated—some retailers raise prices before sales.
Is 30% off a better deal than $30 off?
It depends on the original price: On $100: 30% off = $30 off = Same deal. On $150: 30% off = $45 off > $30 off = 30% better. On $80: 30% off = $24 off < $30 off = $30 better. Rule: If price > $100, percentage discounts are usually better. If price < $100, flat discounts may be better.
How much money do I save with 30% off $1,000?
You save $300 and pay $700. Discount: $1,000 × 0.30 = $300. Final price: $1,000 - $300 = $700. Or directly: $1,000 × 0.70 = $700.
What's better for Black Friday: 30% off or 25% off + free shipping?
Calculate both: 30% off $100 = Pay $70 + shipping (e.g., $5-10) = $75-80 total. 25% off $100 + free ship = Pay $75 + $0 = $75 total. If shipping > $5, the second deal is often better. Always calculate the total cost including shipping!
Do all stores offer 30% off during Black Friday?
No, discount amounts vary: Electronics: 10-30% (high-ticket items). Clothing: 30-50% (fast fashion, seasonal). Furniture: 20-40% (clearance models). Toys: 20-30% (popular items). 30% is a solid discount but not the deepest. Watch for 40-50% off on older inventory.
