Discount Calculator
Find savings and final price after discount
About Discount Calculator
Discount Calculator answers three questions shoppers and retailers face every day: what is the final price after a given percentage off, how much money is saved, and — working in reverse — what was the original price before the discount was applied. The tool supports single discounts, stacked double discounts for layered promotions (such as 30% off followed by an extra 10% off), and a reverse-lookup mode where you enter the sale price and the discount rate to recover the original. Stacked discounts compound rather than add — 30% then 10% extra equals 37% off the original price, not 40%, which surprises many shoppers. An effective-discount field shows the true combined rate so you can compare deals fairly. Optional tax handling lets you apply the discount before or after sales tax depending on the jurisdiction and retailer policy. The tool works with any currency — dollars, euros,.
Why use Discount Calculator
Exact Money Saved
Shows the absolute monetary saving alongside the percentage, so you can decide whether a deal is worth the effort. A 40% discount on a cheap item may save less than a 15% discount on an expensive one.
Reverse Price Lookup
Enter the sale price and the percentage off to instantly recover the original list price. Useful for checking whether an advertised markdown matches a retailer's claimed 'was' price.
Stacked Discount Math Explained
30% + 10% is not 40% off — it is 37%. The tool explains compounding discounts and shows the effective combined rate, which prevents the common mistake of assuming stacked percentages add linearly.
Tax-aware Calculation
Apply the discount before or after sales tax — the correct order depends on your country and retailer. Toggle the option to see the price both ways and ensure your final figure is accurate.
Currency-agnostic
Works with any currency — dollars, euros, pounds, rupees, or any other — because no exchange rate is involved. Simply enter the number and interpret the result in whatever currency you are using.
How to use Discount Calculator
- Enter the original or list price in the price field
- Enter the first discount percentage — for a single discount, this is all you need
- Optionally enter a second discount percentage if the promotion stacks two reductions
- Choose whether discounts apply independently (stacked) or are added together
- Click Calculate or watch the live result showing the final price and amount saved
- To reverse-calculate the original price, switch to Reverse mode, enter the sale price and the discount rate
When to use Discount Calculator
- When a store advertises 25% off and you want to know the final price before reaching the checkout
- When a retailer stacks a clearance discount with an additional coupon code and you want to calculate the true effective discount
- When you see a sale price tag and want to verify that the claimed discount matches the advertised original price
- When planning a product promotion or campaign and need to calculate what price to display at different discount levels
- When comparing two deals on different products to find out which one saves more in absolute monetary terms
- When building a pricing spreadsheet and need to quickly batch-verify that margin targets are met after discounts
Examples
Single discount
Input: Original: $120, Discount: 25%
Output: Final price: $90.00 — Amount saved: $30.00
Stacked discounts
Input: Original: $200, First discount: 30%, Second discount: 10%
Output: Final price: $126.00 — Saved: $74.00 — Effective discount: 37%
Reverse lookup — find original
Input: Sale price: ₹2,250, Discount: 25%
Output: Original price: ₹3,000 — Savings confirmed: ₹750
Tips
- Two stacked discounts of 30% and 10% equal 37% off — not 40%. Always calculate the effective combined rate to compare deals accurately
- Use reverse mode to check whether a retailer's 'original price' on a sale tag is genuine — enter the sale price and the discount percentage to recover the implied original
- Apply discount before tax in most US contexts; if the price shown already includes VAT (common in EU countries), the discount reduces the gross price
- BOGO 50% off the second item is a 25% effective discount on both items together — not 50%
- Save a link to a multi-item comparison with the discount filled in so you can share the deal calculation with a friend or partner
Frequently Asked Questions
How do stacked discounts compound?▾
With stacked discounts, the second percentage is applied to the already-reduced price, not the original. For a $100 item with 30% off then 10% off: first step gives $70, second step takes 10% of $70 to give $63. The effective discount is 37%, not 40%.
Is 30% off then 10% off the same as 40% off?▾
No — it is 37% off. Stacking two percentage discounts always produces a combined rate that is less than their arithmetic sum because the second discount applies to a smaller base. The formula for two stacked rates a and b is: effective rate = 1 − (1 − a/100) × (1 − b/100).
How do I find the original price from a sale price?▾
Use reverse mode. The formula is: original price = sale price ÷ (1 − discount rate). For a sale price of $75 at 25% off, the original is $75 ÷ 0.75 = $100. Many advertised 'was' prices do not survive this check.
Should discount be applied before or after tax?▾
In most US states, discounts are applied before sales tax so you pay tax only on the final discounted price. In some European jurisdictions, VAT is included in the displayed price and the discount reduces the full inclusive amount. Toggle the tax option in the calculator to model both scenarios.
What is BOGO (buy-one-get-one) effective discount?▾
BOGO means you buy one item at full price and receive a second free, for a total cost of one item covering two. The effective per-item discount is 50% if both items are the same price. BOGO 50% (second item at half price) is a 25% effective discount on the pair.
How do clearance discounts differ from coupons?▾
Clearance discounts reduce the shelf or list price directly, so the reduced price is what you pay before any coupons. Coupons typically apply to the stated selling price and can sometimes stack with clearance markdowns, though retailer policies vary. This calculator can model both by treating each as a stacked discount layer.
Can two coupon codes stack in real stores?▾
Stacking depends entirely on the retailer's coupon policy. Many stores explicitly state 'one coupon per transaction' or exclude sale items. However, the mathematical calculation of what the effective discount would be is exactly what this tool handles — useful for checking the deal before finding out at the register.
What is the difference between discount and rebate?▾
A discount reduces the purchase price at the point of sale — you pay less immediately. A rebate is a partial refund claimed after purchase, often requiring a form submission or receipt upload. The immediate value is the same if both are honoured, but rebates carry a redemption risk and a time delay.

Glossary
- List Price
- The standard, undiscounted price at which a product is offered before any promotions, coupons, or markdowns are applied. Also called the original price, retail price, or marked price.
- Sale Price
- The price a buyer actually pays after a discount has been applied. Equal to the list price minus the discount amount.
- Discount Rate
- The percentage by which a price is reduced. A 25% discount rate means the buyer pays 75% of the list price.
- Effective Discount
- The true combined percentage reduction when two or more discounts are stacked. Always less than the arithmetic sum of the individual rates because each successive discount applies to a smaller base.
- Markdown
- A permanent or semi-permanent reduction in the selling price of a product, typically used for clearance of slow-moving inventory. Distinguished from a promotional discount, which is temporary.
- Stacked Discount
- A pricing structure where a second discount is applied to an already-discounted price rather than to the original. Stacked discounts compound mathematically: the effective rate is 1 − (1 − d1) × (1 − d2).
