The arithmetic, line by line
| Step | Calculation | Result |
|---|---|---|
| Discount rate as a decimal | 40 ÷ 100 | 0.40 |
| Discount amount | $49.99 × 0.40 | $20.00 |
| Final price | $49.99 − $20.00 | $29.99 |
| Price paid, share of original | $29.99 ÷ $49.99 × 100 | 60% |
On the price ladder $49.99 is entry 9 of 18, sitting $10.00 above $39.99 and $10.00 below $59.99. The same 40% label saves $16.00 on $39.99 against $20.00 here, so the percentage is identical and the money is not — the shelf label tells you the rate, never the amount.

What is 40% off $49.99?
$29.99. The discount is 40% of $49.99, which is $20.00, and that comes straight off the price: $49.99 − $20.00 = $29.99.
How much do I save at 40% off $49.99?
$20.00 on a $49.99 item, which is the 40% that comes off before the till total of $29.99. 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 $49.99 the first cut leaves $29.99, and a second 40% takes it to $18.00.
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 $32.39 on a $29.99 subtotal, not 8% of $49.99. There are exceptions for manufacturer coupons and mail-in rebates, but a shelf discount is applied first.
