The arithmetic, line by line
| Step | Calculation | Result |
|---|---|---|
| Discount rate as a decimal | 50 ÷ 100 | 0.50 |
| Discount amount | $129.99 × 0.50 | $65.00 |
| Final price | $129.99 − $65.00 | $65.00 |
| Price paid, share of original | $65.00 ÷ $129.99 × 100 | 50% |
At $1.30 per percentage point, the 10-point move up to 60% changes the saving by $12.99 on a single unit. Two units bought at 50% save $130.00 between them, which is $52.01 more than one unit at 60% ($77.99) — quantity and discount rate are separate levers and they do not trade evenly.

$65.00. The discount is 50% of $129.99, which is $65.00, and that comes straight off the price: $129.99 − $65.00 = $65.00.
How much do I save at 50% off $129.99?
$65.00 on a $129.99 item, which is the 50% that comes off before the till total of $65.00. The share you still pay is 50%, and sales tax is charged on that smaller figure rather than on the original.
Is 50% off plus another 50% off the same as 100% off?
No. Stacked percentages multiply, so 50% then 50% is 75% off in total, not 100%. On $129.99 the first cut leaves $65.00, and a second 50% takes it to $32.50.
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 $70.19 on a $65.00 subtotal, not 8% of $129.99. There are exceptions for manufacturer coupons and mail-in rebates, but a shelf discount is applied first.
