What does "save up to 50%" legally mean?

It means the maximum discount in the store or category is 50%, but individual items may only be discounted by 10% or 15%.

Discount Calculator

Determine your exact final out-of-pocket cost and dollar savings after store markdowns, coupons, and local sales taxes.

Mathematical Formula & Calculation Method

Discount Amount = Original Price × (Discount % / 100) | Final Price = Original Price - Discount Amount

Formula Components:

Savings = Original Price × (Discount Percentage / 100)
Pre-tax Sale Price = Original Price - Savings
Final Out-of-Pocket = Pre-tax Sale Price + (Pre-tax Sale Price × Tax Rate / 100)

How It Works

Enter the item sticker price before any markdowns.

Input the discount percentage offered by the retailer.

Optionally specify a second stacked promo code or local sales tax rate.

The calculator computes your total savings and final register total.

Practical Calculation Examples

30% Off a $120 Winter Coat

A retail jacket with an MSRP of $120 is marked down 30% during a clearance event.

Step 1:Calculate dollar discount: $120 × (30 / 100) = $36.00.

Step 2:Subtract savings from original price: $120 - $36 = $84.00.

Outcome: You save $36.00 and pay $84.00 before tax.

Stacked Coupon: 20% Store Sale + Extra 10% VIP Coupon on $80

Applying an additional 10% coupon on an already discounted 20% item.

Step 1:First 20% discount: $80 - $16 = $64.00.

Step 2:Second 10% coupon applied to $64: $64 × 0.10 = $6.40 savings.

Step 3:Final price: $64 - $6.40 = $57.60 total savings of $22.40 (28% effective discount, not 30%).

Outcome: Final price is $57.60 with total savings of $22.40.

Important Assumptions & Estimator Guidance

Discounts are applied before sales tax unless local regulations stipulate post-tax rebates.
Stacked discounts are calculated sequentially rather than summed additively.
Prices cannot drop below $0.00.

Common Pitfalls & Mistakes to Avoid

Adding stacked discounts together directly

A 20% discount followed by a 20% coupon does not equal 40% off. It equals 36% off because the second discount applies to the reduced price.

Correction: Apply subsequent percentage discounts sequentially to each intermediate subtotal.
