What is a Good Discount Percentage?
Whether a discount is “good” depends entirely on context — the product category, the original price, and what the item normally sells for. This guide explains how retailers think about discounts and how you can tell whether a percentage off represents genuine value.
Discount tiers: what each level typically means
| Discount | What it typically signals |
|---|---|
| 5–10% | Loyalty reward, minor promotion, or introductory offer |
| 10–20% | Standard promotional discount; routine sale |
| 20–30% | Meaningful sale; seasonal clearance starting price |
| 30–50% | Strong sale; end-of-line or seasonal clearance |
| 50–70% | Deep clearance; retailer moving old stock |
| 70%+ | Liquidation, closing-down sale, or inflated original price |
The original price problem
A 50% discount is only meaningful if the original price was genuine. Retailers sometimes inflate the “original” price before a sale to make the discount look larger than it is. This practice — known as reference pricing or was/now pricing — is regulated in many countries but still common.
Before buying, check the item’s price history on a comparison site. A 40% discount on a product that was only at the full price for two days before the sale is not the same as 40% off a stable year-round price.
Industry benchmarks
| Sector | Typical promotional discount | Deep sale / clearance |

| Fashion & clothing | 20–30% | 50–70% |
| Electronics | 5–15% | 20–40% |
| Groceries / FMCG | 10–25% | 30–50% |
| Books | 10–20% | 40–60% |
| Software / SaaS | 10–20% | 30–50% |
| Travel | 10–20% | 30–50% |
| B2B / wholesale | 20–40% | 50%+ |
How to calculate your actual saving
Use the Discount Calculator to find the exact amount saved and the sale price for any percentage off.
Manually: Saving = Original price × Discount % ÷ 100.
Example: 30% off £120: saving = £36, you pay £84.
Stacked discounts
If a retailer offers an extra 10% off an already discounted price, the combined saving is not the sum of the two percentages. Apply them sequentially:
- Original: $100
- After 30% off: $70
- After a further 10% off $70: $63
- Total saving: $37 (37%, not 40%)
FAQ
Is a 20% discount good?
For most retail categories, 20% is a genuine and meaningful promotional discount. It is the most common standard sale level and represents a saving most shoppers notice.
Is a 10% discount worth it?
It depends on the price. 10% off a £10 item is £1 — negligible. 10% off a £2,000 appliance is £200 — significant. Evaluate the absolute saving, not just the percentage.
What discount percentage do retailers typically offer on Black Friday?
Discounts vary widely. Genuine Black Friday deals in electronics are often 10–30%. Clothing can reach 50–70%. Be cautious of discounts above 50% — check whether the original price was recently inflated.
How do multiple discounts stack?
Apply them one at a time. A 20% discount followed by a 10% discount gives a combined saving of 28%, not 30%. Use the Discount Calculator to check.
