# Complete Discount Calculator Guide: Save More on Every Purchase

## Understanding Discounts

A discount is a reduction in the original price of a product or service. Whether you're shopping online, in-store, or taking advantage of seasonal sales, understanding how to calculate discounts is essential for smart shopping and budgeting.

## The Discount Formula

The basic discount calculation uses this simple formula:

**Discount Amount = Original Price × Discount Percentage ÷ 100**

**Final Price = Original Price - Discount Amount**

Or more directly:

**Final Price = Original Price × (1 - Discount Percentage ÷ 100)**

## Real-World Examples

### Example 1: Simple Percentage Discount
- Original Price: $50
- Discount: 20%
- Discount Amount: $50 × 20 ÷ 100 = $10
- Final Price: $50 - $10 = $40
- You Save: $10

### Example 2: Multiple Item Discount
- Original Price for 3 items: $150
- Store Discount: 15% off
- Discount Amount: $150 × 15 ÷ 100 = $22.50
- Final Price: $150 - $22.50 = $127.50
- You Save: $22.50

### Example 3: Stacked Discounts
When you have multiple discounts, apply them sequentially:
- Original Price: $100
- First Discount: 10% = $100 - $10 = $90
- Second Discount: 5% of $90 = $90 - $4.50 = $85.50
- Total Savings: $14.50 (14.5% overall)

## Types of Discounts

### Percentage Discounts
The most common type, expressed as a percentage off the original price. Examples: 20% off, half-price sales, clearance events.

### Fixed Amount Discounts
A specific dollar amount subtracted from the price. Examples: $5 off, $10 off. Percentage discount = (Fixed Amount ÷ Original Price) × 100

### Buy More, Save More
Bulk discounts where higher quantities get steeper discounts. Example: Buy 1 at full price, buy 2 get 15% off, buy 3+ get 25% off.

### Loyalty Program Discounts
Member-exclusive offers that reward repeat customers with percentage or point-based discounts.

## Strategic Shopping Tips

1. **Compare Unit Prices**: Larger quantities may have higher discounts, but check the unit price to ensure it's actually a better deal.

2. **Stack Discounts When Possible**: Many retailers allow combining coupon codes, loyalty discounts, and sale prices—always check the terms!

3. **Watch Clearance Sections**: Electronics, clothing, and seasonal items often have discounts up to 50-70% off.

4. **Use Discount Apps**: Apps like Honey, RetailMeNot, and Ibotta automatically find and apply coupons at checkout.

5. **Plan Around Sales Cycles**: Back-to-school sales, holiday weekends, and seasonal changes are prime times for discounts.

6. **Check Tax Calculations**: Sales tax is typically applied after the discount is subtracted from the original price.

## Common Discount Scenarios

### Scenario 1: Black Friday Shopping
- Original Price: $200 laptop
- Black Friday Discount: 30%
- Discount Amount: $200 × 30 ÷ 100 = $60
- Sale Price: $140
- Plus an additional $20 coupon? Final: $120

### Scenario 2: Restaurant Coupons
- Original Bill: $75
- Coupon Discount: 20% off
- Discount Amount: $75 × 20 ÷ 100 = $15
- Bill After Discount: $60
- Tip Calculation: Usually calculated on the pre-discount amount ($75), so 20% tip = $15, bringing total to $75

### Scenario 3: Seasonal Clearance
- Original Price: $400 sofa
- Store Clearance: 50% off
- Sale Price: $200
- Additional Loyalty Discount: 10% off sale price
- Additional Discount: $200 × 10 ÷ 100 = $20
- Final Price: $180

## Advanced Discount Calculations

### Finding Original Price from Sale Price
If you know the final price and discount percentage:

**Original Price = Final Price ÷ (1 - Discount Percentage ÷ 100)**

Example: Final price is $60 after 40% discount
Original Price = $60 ÷ (1 - 0.40) = $60 ÷ 0.60 = $100

### Calculating Discount Percentage from Prices
If you know original and sale prices:

**Discount Percentage = ((Original Price - Sale Price) ÷ Original Price) × 100**

Example: Original $80, Sale $60
Discount = ((80 - 60) ÷ 80) × 100 = 25%

## Tax and Discounts

Important: Most jurisdictions apply sales tax AFTER the discount:

- Original Price: $100
- Discount (20%): -$20
- Subtotal: $80
- Sales Tax (8%): $6.40
- Total: $86.40
