The arithmetic, line by line
| Step | Calculation | Result |
|---|---|---|
| Discount rate as a decimal | 10 ÷ 100 | 0.10 |
| Discount amount | $4.99 × 0.10 | $0.50 |
| Final price | $4.99 − $0.50 | $4.49 |
| Price paid, share of original | $4.49 ÷ $4.99 × 100 | 90% |
This is the bottom rung of the 10 discounts the site publishes for $4.99: it returns $0.50, and reaching the 75% row would take another $3.24 off the same shelf label. One percentage point on $4.99 is worth $0.05, which is why the 5-point step to 15% adds just $0.25.

Frequently asked
What is 10% off $4.99?
$4.49. The discount is 10% of $4.99, which is $0.50, and that comes straight off the price: $4.99 − $0.50 = $4.49.
How much do I save at 10% off $4.99?
$0.50 on a $4.99 item, which is the 10% that comes off before the till total of $4.49. The share you still pay is 90%, and sales tax is charged on that smaller figure rather than on the original.
Is 10% off plus another 10% off the same as 20% off?
No. Stacked percentages multiply, so 10% then 10% is 19% off in total, not 20%. On $4.99 the first cut leaves $4.49, and a second 10% takes it to $4.04.
Does sales tax apply before or after the discount?
After, in every US state that taxes the sale. Tax is charged on what you actually pay, so at 8% you owe $4.85 on a $4.49 subtotal, not 8% of $4.99. There are exceptions for manufacturer coupons and mail-in rebates, but a shelf discount is applied first.
