Frequently Asked Questions

How do I calculate a discount?

Multiply the original price by the discount percentage divided by 100, then subtract the discount amount from the original price. For example, a $100 item with a 20% discount costs $80 before tax.

How do multiple discounts work?

Each percentage discount applies to the price remaining after the previous discount. A 20% discount followed by an additional 10% discount reduces the original price by 28% overall, not 30%.

Does this calculator include sales tax?

Yes. Enter your tax rate and the calculator applies it to the discounted subtotal. Actual tax treatment may vary by jurisdiction and product type.

How do I calculate the percentage saved?

Divide the total discount by the original subtotal and multiply by 100. This calculator shows the effective discount percentage for all applied discounts.

Can I calculate the final price for multiple items?

Yes. Enter the unit price and quantity. The calculator displays the discounted subtotal, tax, total purchase price, and final cost per item.

Is this discount calculator free?

Yes. All calculations run directly in your browser. No account, paid service, API key, or external calculation server is required.
