Discount Calculator

Black Friday deals, clearance racks, or "30% off" coupons? Don't let the red stickers fool you. Calculate the final price (and the tax) instantly.

What this calculator does

• Final Price: What you actually pay.
• Amount Saved: How much you kept in your pocket.
• Tax Inclusion: Don't forget Uncle Sam's cut.

The Formula

$\text{Current Price} = \text{Original} \times (1 - \text{Discount})$ $\text{Tax} = \text{Price} \times \text{Tax Rate}$

Unlike math class, here's what that means

• 50% Off: Half price.
• 75% Off: Quarter price.
• Buy One Get One Free: Effectively 50% off (if they are same price).

Example Calculation

Jeans: $80. Sale: 30% Off. Tax: 8%.

1. Discount: $80 \times 0.30 =$24$.
2. Sale Price: $80 - 24 =$56$.
3. Tax: $56 \times 0.08 =$4.48$.
4. Total: $60.48.

Did You Know? 💡

• The "Double Discount" Trap: Taking "Extra 20% off" usually applies to the sale price, not the original.
  • $100 \rightarrow 50\% \text{ Off} =$50$.
  • Extra 20% Off \50 = 40\. (Total discount is 60%, not 70%).
• Anchor Pricing: Stores mark items up just to mark them down. "Was $100, Now $50" sells better than "Price $50," even if the value is identical.

Expert Insight

Stacked Coupons: Always apply dollar-off coupons before percent-off coupons if possible? Actually, no.

• Math check: $(100 - 10) \times 0.8 = 72$.
• $(100 \times 0.8) - 10 = 70$. Apply % first, then $ off for the best deal.

Why this matters

Retail therapy is fun until the credit card bill arrives. Knowing the real price stops impulse buys.
