How to use it

Use this for arithmetic on a stated price. It cannot verify whether a merchant’s original-price or savings claim is truthful or lawful.

1. Enter the original price and choose a percentage or fixed discount.
2. Optionally add a second percentage that applies to the already reduced price.
3. Review final price, savings, and the effective combined percentage.

Worked example

Input

100 with 20% off, then another 10% off

Output

72 final price; 28 saved; 28% effective discount

20% + 10% is not 30% because the second reduction applies to 80.

Method and definitions

• Percentage: original × (1 − rate).
• Fixed: original − discount amount.
• Successive percentage: after-first × (1 − second rate).

Limits and edge cases

• Taxes, shipping, eligibility, rebates, financing, and multi-item promotions are excluded.
• A fixed discount may not exceed the original price; percentages may not exceed 100%.
• The calculation does not substantiate advertising claims.
