2. Select a discount percentage from preset buttons or enter a custom value.
3. Optionally add a second discount (stacked discounts).
4. Optionally add sales tax to get the final out-of-pocket amount.
5. Click Calculate to see the breakdown.

Who Needs This Tool?

• Shoppers — know exactly how much you'll pay during sales and promotions
• Budget-conscious consumers — compare deals and stacked discounts to find the best value
• Retail employees — quickly calculate prices for customers during multi-discount promotions
• Small business owners — determine final pricing after supplier discounts and applicable tax

How Stacked Discounts Work

Stacked discounts apply sequentially, not cumulatively. For example:

• A $100 item with a 25% off sale = $75
• A $100 item with 25% off plus an extra 10% coupon = $67.50 (25% off first, then 10% off the reduced price)
• This is not the same as a single 35% discount which would be $65

Frequently Asked Questions

What is the difference between sequential and combined discounts?

Sequential discounts (what this calculator uses) apply one after another. Combined discounts add the percentages together. Sequential almost always results in a higher final price than combined. For example, 20% + 20% sequentially = 36% total saving, not 40%.

Does this calculator account for tax rules?

The sales tax field applies a simple percentage to the discounted price. Actual tax treatment varies by jurisdiction — some regions apply tax before discounts, some after, and some have different rates for different product categories. This calculator provides an estimate, not a legally binding tax calculation.

How is the effective discount calculated?

The effective discount is the total savings divided by the original price. For a $100 item that ends up costing $60 after stacked discounts, you saved $40 — an effective discount of 40%. This is the single percentage that would produce the same final price.

Can I calculate discounts on multiple items at once?

This calculator handles one item at a time. For bulk calculations, enter the subtotal as the original price. For percentage-based calculations, see our Percentage Calculator.
