The arithmetic, line by line
| Step | Calculation | Result |
|---|---|---|
| Discount rate as a decimal | 15 ÷ 100 | 0.15 |
| Discount amount | $4.99 × 0.15 | $0.75 |
| Final price | $4.99 − $0.75 | $4.24 |
| Price paid, share of original | $4.24 ÷ $4.99 × 100 | 85% |
On the price ladder $4.99 is entry 1 of 18, with nothing cheaper on the list, $5.00 below $9.99. The same 15% label saves $1.50 on $9.99 against $0.75 here, so the percentage is identical and the money is not — the shelf label tells you the rate, never the amount.

If a second discount stacks
"Take an extra 20% off sale prices" is a second cut on the already-reduced price, not on the original. That is why the totals below do not add up to 25% or 35%.

|---|---|---|---|
| Extra 10% off | $4.24 | $3.82 | 23.5% total |

Frequently asked
What is 15% off $4.99?
$4.24. The discount is 15% of $4.99, which is $0.75, and that comes straight off the price: $4.99 − $0.75 = $4.24.
How much do I save at 15% off $4.99?
$0.75 on a $4.99 item, which is the 15% that comes off before the till total of $4.24. The share you still pay is 85%, and sales tax is charged on that smaller figure rather than on the original.
Is 15% off plus another 15% off the same as 30% off?
No. Stacked percentages multiply, so 15% then 15% is 27.8% off in total, not 30%. On $4.99 the first cut leaves $4.24, and a second 15% takes it to $3.61.
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 $4.58 on a $4.24 subtotal, not 8% of $4.99. There are exceptions for manufacturer coupons and mail-in rebates, but a shelf discount is applied first.
