How It Works
Discount calculations appear everywhere — retail sales, e-commerce offers, wholesale pricing, invoice discounts, and financial planning. There are three common problems: finding the discounted price (most common), finding what discount percentage was applied, or reverse-calculating the original price from a discounted price. Shops usually show a list price (MSRP in the US, RRP in the UK, MRP in India) alongside the sale price, and the real saving is the percentage off that list price. Note that 'up to X% off' in advertisements is the maximum — average discounts are usually much lower.
Formula
Sale Price = Original Price × (1 − Discount%/100). Savings = Original − Sale Price. Discount% = (Savings / Original) × 100.
Frequently Asked Questions
How do I calculate the price after a discount?
Sale Price = Original Price × (1 − Discount/100). For a 30% discount on $100: Sale Price = 100 × (1 − 0.30) = 100 × 0.70 = $70. You save $30. Alternatively: savings = 100 × 0.30 = $30, then subtract from original.
How do I find the original price from a discounted price?
If you know the sale price and discount percentage: Original Price = Sale Price ÷ (1 − Discount/100). Example: an item costs $42 after a 30% discount. Original = 42 ÷ 0.70 = $60. This is useful when you see a sale price but want to know the original price.
How do I calculate successive discounts?
Successive discounts are NOT additive. A 20% discount followed by a 10% discount is NOT 30% total. Effective discount = 1 − (1−d1) × (1−d2). For 20% then 10%: effective = 1 − 0.80 × 0.90 = 1 − 0.72 = 28%. On $1,000: after 20% → $800, then 10% off $800 → $720. Total savings = $280 (28% of original).
What is the difference between discount and cashback?
A discount reduces the price upfront at the time of purchase. Cashback is a post-purchase credit — you pay the full price and receive a portion back later (in your wallet, bank account, or as reward points). The effective savings from cashback may be delayed or conditional. Both can be expressed as a percentage of the original price, but cashback often has conditions (minimum spend, specific payment method, expiry).
What are MRP, MSRP and list price?
A list price is the price a seller starts from before any discount: MSRP (manufacturer’s suggested retail price) in the US, RRP (recommended retail price) in the UK, and MRP (Maximum Retail Price) in India. In India the MRP is the highest price at which a product can legally be sold, inclusive of all taxes, and it is printed on the packaging under the Legal Metrology Act, so sellers can charge less but not more. Elsewhere sellers can charge above or below the suggested price. When comparing offers, compare against the same reference price to judge the real discount.
How are trade discounts different from retail discounts?
A trade discount is a reduction given by manufacturers or wholesalers to retailers/distributors (B2B), typically not shown on the invoice — the invoice is written at the discounted price. A cash discount is given for early payment. A retail discount (what this calculator handles) is given to end consumers off the listed price. Sales tax, VAT and GST are normally charged on the price after the discount.
