40% Off $4.99 — You Pay $2.99
40% of $4.99 is $2.00, so the price drops from $4.99 to $2.99. 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 | 40 ÷ 100 | 0.40 |
| Discount amount | $4.99 × 0.40 | $2.00 |
| Final price | $4.99 − $2.00 | $2.99 |
| Price paid, share of original | $2.99 ÷ $4.99 × 100 | 60% |
At $0.05 per percentage point, the 10-point move up to 50% changes the saving by $0.50 on a single unit. Two units bought at 40% save $4.00 between them, which is $1.50 more than one unit at 50% ($2.50) — quantity and discount rate are separate levers and they do not trade evenly.
With sales tax on top
Tax is charged on the discounted amount, so the rate applies to $2.99 rather than $4.99.
| Tax rate | You pay | Tax portion |
|---|---|---|
| 5% | $3.14 | $0.15 |
| 6% | $3.17 | $0.18 |
| 7% | $3.20 | $0.21 |
| 8% | $3.23 | $0.24 |
| 9% | $3.26 | $0.27 |
| 10% | $3.29 | $0.30 |
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 50% or 60%.

|---|---|---|---|
| Extra 10% off | $2.99 | $2.69 | 46% total |

Frequently asked
What is 40% off $4.99?
$2.99. The discount is 40% of $4.99, which is $2.00, and that comes straight off the price: $4.99 − $2.00 = $2.99.
How much do I save at 40% off $4.99?
$2.00 on a $4.99 item, which is the 40% that comes off before the till total of $2.99. The share you still pay is 60%, and sales tax is charged on that smaller figure rather than on the original.
Is 40% off plus another 40% off the same as 80% off?
No. Stacked percentages multiply, so 40% then 40% is 64% off in total, not 80%. On $4.99 the first cut leaves $2.99, and a second 40% takes it to $1.80.
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 $3.23 on a $2.99 subtotal, not 8% of $4.99. There are exceptions for manufacturer coupons and mail-in rebates, but a shelf discount is applied first.
