Instantly calculate sale prices, total dollars saved, stacked discounts, and sales tax.
When a store advertises a "30% off sale plus an extra 20% off at checkout", the discounts are almost always applied sequentially rather than added together.
For example, on a $100 item:
1. First 30% discount drops the price to $70.
2. The extra 20% applies to the new $70 price (20% of $70 = $14).
3. Final price is $56 (an effective 44% total discount, not 50%).
Our calculator handles both single and stacked discounts automatically, so you always know exactly what you'll pay at the register.
