Frequently Asked Questions

How do I calculate a discount?▾

Multiply the original price by (1 - discount/100). For example, 25% off $80: $80 × (1 - 0.25) = $60.

Can I stack multiple discounts?▾

Yes! The calculator lets you apply sequential discounts. Note: stacking 20% + 10% is NOT the same as 30% — it's $100 → $80 → $72 (28% total).

Does it calculate sales tax?▾

Yes! Enter your local sales tax rate and see the final price after both discount and tax.
