Practical Example with Your Values
Let's apply these formulas to calculate 90% off $200:
Step 1: Calculate the amount you save using formula (a):
Amount Saved = $200 × 90% ÷ 100

Sale Price = $200 × 0.1
Sale Price = $20

Is sales tax calculated before or after the 90% discount?
Sales tax is always calculated after the discount is applied. For your $200 purchase with 90% off, you first calculate the discounted price ($20), then apply the sales tax to that amount.
For example, with an 8% sales tax: $20 × 1.08 = $21.6. This means you save on both the purchase price and the tax amount, since tax is calculated on the lower discounted price rather than the original $200.
Should I use a credit card rewards program for this $20 purchase?
Yes, combining your 90% discount with credit card rewards can maximize savings. If your card offers 2% cashback, you'll earn an additional $0.4 back on your $20 purchase. Combined with your $180 discount savings, your total savings would be $180.4.
Some cards offer higher rewards (3-5%) in specific categories. Shopping portals can add another 1-10% cashback. However, only use credit cards if you pay the balance in full - interest charges would negate any savings from the discount and rewards combined.
