30% off — a serious markdown
At 30% off, you pay 70 cents on the dollar. This level of discount is common in department store sales, subscription cancellation offers, and direct-to-consumer fashion promotions. It's the point where most shoppers feel they're getting a genuinely good deal.
Mental math tip: to find 30% off, calculate 10% (move the decimal) then multiply by 3. For a $90 sweater: 10% = $9, × 3 = $27 off, sale price $63. The calculator above handles any price instantly — no mental arithmetic needed.
How to calculate 30% off
Multiply the original price by 0.70 (which is 1 − 30/100):
Sale Price = Original × 0.70
For example, 30% off $90:
$90 × 0.70 = $63.00. You save
$27.00.
