Frequently asked questions
How is sale price computed?▾
sale = original × (1 − discount/100).
Does it handle stacked discounts?▾
No — for stacked offers (e.g. 20% off + extra 10%), apply sequentially: chain two discount calculations.
Includes tax?▾
No — use the sales tax calculator after computing the discounted price.
