How do I calculate a discount?
Sale price = original × (1 − discount%). 25% off $120 is $90, and you save $30.
How do I stack coupons?
Apply them in the order the store does (often percent off merchandise, then a dollar coupon). Run the percent first in this calculator, then subtract extra dollars.
Is 30% off better than $30 off?
On $120, 30% off saves $36, so the percent wins. On $80, $30 off saves more. Compare both.
