Calculate sale prices and shopping savings
Description
The Percent Off Calculator is the perfect companion for retail shopping and clearance hunting. It quickly determines the final price of an item after a discount is applied. Uniquely, it also supports Stacked Discounts (e.g., “Take 20% off already marked down items”), ensuring you know the exact price before you reach the checkout.
Inputs
- Original Price: The starting or “MSRP” price on the tag ($).
- Percent Off: The primary discount being offered (%).
- Additional % Off (Stacked): An optional secondary discount (like a coupon or clearance bonus) that is applied after the first discount (%).
Outputs
- Final Price: The amount you will pay at the register (before tax) ($).
- Total Savings: The total dollar amount discounted from the original price ($).
Chart
- N/A: This tool provides an immediate numeric shopping result.
“Good to Know”
- The “Stacked” Math: If an item is 20% off plus an extra 20% off, it is not 40% off. It is 36% off. This is because the second 20% is taken off the already reduced price.
- Use this tool to compare a “Buy One Get One Free” (50% off each) versus other seasonal sales.
- Don’t forget to account for your local Sales Tax after finding the final price!
