Find the sale price, amount saved, and percentage off — instantly.
Sale price = Original price × (1 − discount% ÷ 100). For a 20% discount on $100: $100 × 0.80 = $80 sale price. You save $20.
% off = ((Original price − Sale price) ÷ Original price) × 100. If something was $80 and is now $60: ((80−60)÷80)×100 = 25% off.
