Results
Enter the original price and discount percentage(s), then tap Calculate to see your savings.
This calculator applies percentage discounts one after another (stacked), then applies sales tax to the discounted price.
How stacked discounts work
  • A 20% discount on $100 makes the price $80.
  • Adding another 10% discount is 10% off the discounted price ($80 → $72), not 30% off the original.

This tool shows:

  • Total savings compared to the original price.
  • Final price before tax after all discounts.
  • Final price with tax when a tax rate is provided.

Numbers are rounded to two decimal places for currency-style output. Always check the store receipt for the exact amount charged.
