Discount Calculator: Find Your Final Sale Price Instantly

We all love a good sale. Whether it is Black Friday, a clearance event, or a special coupon code, seeing "20% OFF" is always exciting. However, trying to figure out exactly what you will pay at the register—especially when you need to factor in local sales tax—can turn a fun shopping trip into a stressful math problem.

Our free online Discount Calculator is the perfect shopping companion. Designed for speed and ease of use on mobile devices, it instantly calculates exactly how much money you are saving, and what your final out-of-pocket cost will be after the discount and tax are applied.

How to Use the Calculator

Using the tool takes just seconds. The dynamic receipt on the right will update in real-time as you type:

• Step 1: Enter the Original Price. Look at the sticker price of the item before any sales are applied.
• Step 2: Enter the Discount. Use the quick-select buttons for common sales (10%, 20%, 50%), or manually type in the exact percentage off your coupon provides.
• Step 3: Add Sales Tax (Optional). If you live in an area with sales tax, enter the percentage rate. The calculator is smart enough to apply the tax after the discount has been deducted from the original price, ensuring penny-perfect accuracy.

Understanding "Double Discounts"

Retailers often run promotions like "Take an extra 15% off already reduced clearance items." It is a common misconception to just add the percentages together (e.g., assuming a 20% off item with an extra 15% off means you get 35% off). This is incorrect math.

In reality, the second discount is applied to the new, already reduced price, not the original sticker price. To calculate this correctly, simply use our calculator twice: First, find the new price after the 20% discount. Then, enter that new price as your "Original Price" and apply the 15% discount to find your true final cost.
