The arithmetic, line by line
| Step | Calculation | Result |
|---|---|---|
| Discount rate as a decimal | 15 ÷ 100 | 0.15 |
| Discount amount | $19.99 × 0.15 | $3.00 |
| Final price | $19.99 − $3.00 | $16.99 |
| Price paid, share of original | $16.99 ÷ $19.99 × 100 | 85% |
On the price ladder $19.99 is entry 4 of 18, sitting $5.00 above $14.99 and $5.00 below $24.99. The same 15% label saves $2.25 on $14.99 against $3.00 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 | $16.99 | $15.29 | 23.5% total |

Frequently asked
What is 15% off $19.99?
$16.99. The discount is 15% of $19.99, which is $3.00, and that comes straight off the price: $19.99 − $3.00 = $16.99.
How much do I save at 15% off $19.99?
$3.00 on a $19.99 item, which is the 15% that comes off before the till total of $16.99. 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 $19.99 the first cut leaves $16.99, and a second 15% takes it to $14.44.
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 $18.35 on a $16.99 subtotal, not 8% of $19.99. There are exceptions for manufacturer coupons and mail-in rebates, but a shelf discount is applied first.
