What Is a 50% Off Calculator?
A 50% off calculator works out the final sale price when an item is discounted by half, and shows exactly how much money you keep in your pocket. Because 50 percent is half, the sale price and the amount you save are always equal — both are exactly half of the original price.
How to Use It
Enter the original price of the item and the calculator instantly returns three numbers: the original price, the amount saved, and the final sale price. It is perfect for clearance racks, flash sales, "buy one get one half off" deals, and quick mental-math checks at the register.
The Formula Explained
A 50% discount multiplies the price by the discount rate of 0.5. The amount saved is \(\text{Price} \times 0.5\), and the sale price is the original price minus that saving, which simplifies to \(\text{Price} \times 0.5\) as well. In short, at 50% off you pay half and save half.
$$\text{Sale Price} = \text{Original Price (\$)} \times (1 - 0.5)$$
Worked Example
Suppose a jacket costs $80. The amount saved is \(80 \times 0.5 = \$40\). The sale price is \(80 - 40 = \$40\). So you pay $40 and save $40 — exactly half each way.
FAQ
Is 50% off the same as half price? Yes. Taking 50 percent off is identical to paying half of the original price.
How do I calculate 50% off in my head? Just divide the price by two. For $19.98, half is about $9.99.
Does this include sales tax? No. The calculator shows the pre-tax discounted price. Add any applicable tax to the sale price at checkout.
