About the Discount Calculator
This Discount Calculator makes it effortless to work out how much you’ll pay after a sale and how much you’ll save. Whether you’re shopping during seasonal promotions, evaluating a coupon offer, or planning a bulk- purchase discount, the tool helps you compare options quickly and confidently. You can calculate by entering a discount percentage (e.g., 15% off) or by using a known sale price to back‑solve the equivalent percent off.
To get started, pick a mode: By Percent or By Sale Price. In By Percent, input the original price and the advertised discount rate—your savings and final price appear instantly. In By Sale Price, enter the original price and the promotional price; we’ll compute the discount percentage and the savings automatically. This is handy when a store only shows the final price but you want to know how big the discount really is.
For real‑world accuracy, remember that taxes and fees may apply after discounts, depending on your region and the type of product or service. Some stores apply percentage discounts before fixed‑amount coupons; others do the reverse. While this tool focuses on the core discount math, you can still compare scenarios by adjusting inputs. If you’re price‑matching across retailers, compute the effective percent off for each option so you’re comparing apples to apples. It’s a great way to decide between, say, 30% off one item versus 20% off plus a fixed coupon at another store.

Formula
By Percent: Savings = Original × (Discount% ÷ 100); Final = Original − Savings
By Sale Price: Discount% = (1 − Sale ÷ Original) × 100
Variables
Symbol | Meaning |
---|---|
Original | The list price before any discounts |
Discount % | Percentage reduction from the original price |
Sale Price | The promotional price after discount |
Examples
- Original $120, 25% off → Savings $30; Final $90.
- Original $80, Sale $60 → Discount% = (1 − 60/80) × 100 = 25%.
- Original $200, 10% coupon + store applies tax after discount: Final before tax = $180 (tax varies by region).
Tips
- If multiple discounts apply, check the order: percentages usually apply before fixed coupons unless stated.
- Compare offers using effective discount % so you can evaluate different promos fairly.
- Factor in shipping, tax, or fees to reflect the true out‑the‑door price.
