50% off $100

To calculate 50 percent off 100, multiply $100.00 by 0.5. That gives a savings amount of $50.00.

This is a strong discount, so the savings are large enough to compare against tax, shipping, or quantity.

This is a higher-ticket price, so the dollar savings matter more than the percent alone.

In decimal form, 50% is 0.50 of the original price, so the remaining price is 0.50 of $100.00.

For this stronger promotion, compare the savings against any minimum-spend coupon or free-shipping threshold.
