Frequently Asked Questions
Discount calculations can be done in several ways:
- Percentage discount: Multiply the original price by the discount percentage, then subtract from the original price.
Example: $100 with 20% discount = $100 - ($100 × 0.2) = $100 - $20 = $80 - Fixed amount discount: Simply subtract the discount amount from the original price.
Example: $100 with $15 discount = $100 - $15 = $85 - Calculating discount percentage: Divide the discount amount by the original price, then multiply by 100.
Example: Original price $100, final price $75. Discount amount = $25. Discount percentage = ($25 ÷ $100) × 100 = 25%
A tiered discount applies multiple discounts sequentially, with each discount applying to the price after previous discounts have been applied. This is common in retail when combining coupons, loyalty discounts, or seasonal sales.
For example, if you have a $100 item with a 20% discount followed by an additional 10% discount:
- First discount: $100 - 20% = $80
- Second discount: $80 - 10% = $72
The effective discount rate is 28%, not 30%, because the discounts are applied sequentially rather than added together.
The key to comparison shopping is calculating the unit price - the cost per standard unit (like per ounce, per pound, per item, etc.).
To calculate unit price:
- Calculate the final price after any discounts
- Divide the final price by the quantity or weight
- Compare this unit price across different products
For example, if a 16 oz product costs $4.00 after discount, the unit price is $0.25 per ounce. If a 24 oz product costs $5.52 after discount, the unit price is $0.23 per ounce, making the larger size a better value.
Our comparison calculator does this automatically for you, even converting between different units of measurement.
Not necessarily. While a higher discount percentage might seem attractive, it's important to consider:
- Original price: A 50% discount on an overpriced item might still be more expensive than a fairly priced item with a 20% discount.
- Quality differences: Consider if a heavily discounted item meets your quality requirements.
- Unit price: Compare the final cost per unit (per ounce, per item, etc.) rather than just the discount percentage.
- Need: A big discount on something you don't need is still money spent unnecessarily.
Our comparison calculator helps you see beyond just the discount percentage to make smarter shopping decisions.
Taxes are typically applied after discounts have been calculated. The standard process is:
- Calculate the discounted price
- Apply the tax rate to the discounted price
- Add the tax amount to get the final price
For example, with a $100 item, 20% discount, and 8% tax:
- Discounted price: $100 - 20% = $80
- Tax amount: $80 × 8% = $6.40
- Final price: $80 + $6.40 = $86.40
All our calculators allow you to add tax as an optional step to see the true final price you'll pay at checkout.
