10% of $14.99 is $1.50, so the price drops from $14.99 to $13.49. Below are the same figure with sales tax added, what happens if a second discount stacks on top, and the full tier table for this price so you can compare without retyping it.
The arithmetic, line by line
| Step | Calculation | Result |
|---|---|---|
| Discount rate as a decimal | 10 ÷ 100 | 0.10 |
| Discount amount | $14.99 × 0.10 | $1.50 |
| Final price | $14.99 − $1.50 | $13.49 |
| Price paid, share of original | $13.49 ÷ $14.99 × 100 | 90% |
At $0.15 per percentage point, the 5-point move up to 15% changes the saving by $0.75 on a single unit. Two units bought at 10% save $3.00 between them, which is $0.75 more than one unit at 15% ($2.25) — quantity and discount rate are separate levers and they do not trade evenly.

Frequently asked
What is 10% off $14.99?
$13.49. The discount is 10% of $14.99, which is $1.50, and that comes straight off the price: $14.99 − $1.50 = $13.49.
How much do I save at 10% off $14.99?
$1.50 on a $14.99 item, which is the 10% that comes off before the till total of $13.49. 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 $14.99 the first cut leaves $13.49, and a second 10% takes it to $12.14.
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 $14.57 on a $13.49 subtotal, not 8% of $14.99. There are exceptions for manufacturer coupons and mail-in rebates, but a shelf discount is applied first.
