Discount Calculator
Apply a percentage discount, optionally add sales tax, set a quantity, and see the final payable amount plus the per-item saving. It answers the practical question at checkout: what will I actually pay, and how much did I save.
Discount Calculator
Compute sale price, tax-inclusive total, and savings for single or bulk purchases.
Discount is applied before tax. Adjust tax to your local rate to match the final checkout amount.
Great for quick price checks, bulk purchase planning, and validating online cart totals.
Order of operations matters
Whether tax is applied before or after the discount changes the final number. In most retail systems the discount comes first and tax is charged on the reduced price, which is what this tool does. Applying tax to the full price and then discounting would leave you paying tax on money you never spent.
Stacked discounts also trip people up. A 20% then 10% discount is not 30% off - it is 0.8 x 0.9 = 0.72, so 28% off. The tool computes the real combined effect rather than adding percentages.
Quick uses
It is handy for both shoppers and small sellers.
- Check whether a 'buy more, save more' tier actually beats a flat discount.
- Work out a sale price that lands on a clean final figure after tax.
- Confirm a receipt where the discount and tax both apply.

FAQs
Does it apply tax before or after the discount?▼
After. The discount reduces the price first, then tax is calculated on the discounted amount, which matches standard retail practice. This keeps you from paying tax on the portion you saved.
How do stacked discounts work?▼
They multiply rather than add. Two discounts of 20% and 10% give 0.8 x 0.9 = 0.72 of the original price, i.e. 28% off, not 30%. The tool handles this automatically when you combine them.
Can I see the per-item saving for a bulk order?▼
Yes. Set the quantity and the tool shows both the total saving and the saving per unit, which is useful when comparing bulk pricing.
Is a percentage discount the same as a percentage markup?▼
No. A 50% markup followed by a 50% discount does not return the original price, because each percentage is taken from a different base. Discounts and markups are not symmetric.
