Calculate discounts, sale prices, and savings with our free discount calculator. Find final prices after percentage discounts and compare original vs. discounted prices.
Discount calculations are essential for smart shopping and business pricing strategies. Understanding how discounts work helps you make informed purchasing decisions and maximize your savings.
A percentage reduction from the original price (e.g., 20% off).
A specific dollar amount reduction (e.g., $10 off).
Special pricing when purchasing multiple items.
The basic formula for calculating discounts is:
Minor promotions, loyalty rewards, or early bird specials.
Regular sales, seasonal promotions, or clearance events.
Major sales events, end-of-season clearances, or bulk purchases.
Clearance sales, liquidation events, or special promotions.
To maximize your savings when shopping:
To calculate a percentage discount, multiply the original price by the discount percentage (as a decimal) and subtract from the original price. For example, 20% off $100 = $100 - ($100 × 0.20) = $80.
The discount amount is the actual dollar amount saved, while the savings percentage shows what percentage of the original price you're saving. For example, $20 off a $100 item is both $20 in savings and 20% savings.
It depends on the store's policy. Some retailers allow stacking discounts (coupons + sales), while others don't. Always check the terms and conditions. When combining, discounts are usually applied sequentially, not added together.
To find the original price from a sale price and discount percentage: Original Price = Sale Price ÷ (1 - Discount % / 100). For example, if an item is $80 after a 20% discount: $80 ÷ (1 - 0.20) = $100.
Good discount percentages vary by product type. For clothing, 20-30% is common, while electronics might have 10-15% discounts. Clearance items often have 50%+ discounts. Consider the item's value and your needs when evaluating discounts.
Taxes are typically calculated on the discounted price, not the original price. So if you have a 20% discount, you pay tax on the 80% remaining amount. This means you save on both the discount and the tax on that discounted amount.
