The arithmetic, line by line
| Step | Calculation | Result |
|---|---|---|
| Discount rate as a decimal | 30 ÷ 100 | 0.30 |
| Discount amount | $4.99 × 0.30 | $1.50 |
| Final price | $4.99 − $1.50 | $3.49 |
| Price paid, share of original | $3.49 ÷ $4.99 × 100 | 70% |
On the price ladder $4.99 is entry 1 of 18, with nothing cheaper on the list, $5.00 below $9.99. The same 30% label saves $3.00 on $9.99 against $1.50 here, so the percentage is identical and the money is not — the shelf label tells you the rate, never the amount.

|---|---|---|---|
| Extra 10% off | $3.49 | $3.14 | 37% total |

Frequently asked
What is 30% off $4.99?
$3.49. The discount is 30% of $4.99, which is $1.50, and that comes straight off the price: $4.99 − $1.50 = $3.49.
How much do I save at 30% off $4.99?
$1.50 on a $4.99 item, which is the 30% that comes off before the till total of $3.49. The share you still pay is 70%, and sales tax is charged on that smaller figure rather than on the original.
Is 30% off plus another 30% off the same as 60% off?
No. Stacked percentages multiply, so 30% then 30% is 51% off in total, not 60%. On $4.99 the first cut leaves $3.49, and a second 30% takes it to $2.45.
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 $3.77 on a $3.49 subtotal, not 8% of $4.99. There are exceptions for manufacturer coupons and mail-in rebates, but a shelf discount is applied first.
