Find original price from discounted price
| Item | Value |
|---|
A discount is a reduction from the original (or "regular") price, expressed as a percentage. Discount calculators are used for retail pricing, bulk purchasing negotiations, sale pricing analysis, and commission calculations.
| Original Price | 10% off | 20% off | 30% off | 50% off |
|---|---|---|---|---|
| $50 | $45 | $40 | $35 | $25 |
| $100 | $90 | $80 | $70 | $50 |
| $250 | $225 | $200 | $175 | $125 |
| $1,000 | $900 | $800 | $700 | $500 |
When multiple discounts are applied sequentially, they compound rather than add. A 10% discount followed by a 20% discount on $100:
When discounting GST-inclusive prices, the discount applies to the full price and the GST reduces proportionally. A $110 item (including $10 GST) at 20% off sells for $88 (including $8 GST). The GST is always 1/11th of the final discounted price — not 1/11th of the original price.
How do I calculate a percentage discount?
Discounted price = Original price × (1 − discount/100). For a 25% discount on $200: $200 × (1 − 0.25) = $200 × 0.75 = $150. The discount amount is $200 × 0.25 = $50. To find the original price from a discounted price: Original = Discounted price ÷ (1 − discount%).
What is the ACCC rule on discount pricing in Australia?
The ACCC requires that a 'was/now' price or discount percentage must be based on a genuine previous price — the product must have actually been sold at the higher price for a meaningful period before the discount. Fake or exaggerated discounts (where the 'original' price was never genuinely charged) constitute misleading conduct under Australian Consumer Law.
How do I calculate a discount?
To calculate a discount, multiply the original price by the discount percentage, then subtract it from the price. For 25% off $80: 80 × 0.25 = $20 off, giving $60. This discount calculator does it instantly for any price and percentage.
