The calculation
Step-by-step: how your price is calculated
Here is exactly how your $80.00 final price was derived from the numbers above.
1
Calculate the discount amount
Discount Amount = Original Price x (Discount% / 100)
= $100.00 x (20% / 100)
= $100.00 x 0.2000
2
Subtract the discount
Final Price = Original Price - Discount Amount
= $100.00 - $20.00
3
Alternative: Shortcut multiplier
Final Price = Original Price x (1 - Discount% / 100)
= $100.00 x (1 - 20% / 100)
= $100.00 x 0.8000

Strategy
Quick mental math & common mistakes
For everyday estimates at the checkout lane, no calculator needed:
10% shortcut
Move the decimal one place left. 10% of $85 = $8.50. You can double this to easily find 20%.
5% shortcut
Take half of your 10% shortcut. 5% of $85 = $4.25. Add this to your 10% shortcut to quickly find 15% ($8.50 + $4.25 = $12.75).
25% shortcut
Divide by 4. 25% of $80 = $20.
Mistake: Adding stacked discounts
Two sequential discounts of 20% and 10% are NOT equivalent to a single 30% discount. The second percentage is applied to the already-discounted price: $100 - $20 (20%) - $8 (10%) = a combined 28% reduction, not 30%.
FAQ
Frequently asked questions
Q
How do I calculate a discount?
Multiply the original price by the discount percentage, then divide by 100 to find the discount amount. Subtract that from the original price to get the final sale price. For example, 25% off $80: discount = 80 x 25 / 100 = $20, so the final price is $60.
Q
What is the discount formula?
Discount Amount = Original Price x (Discount % / 100). Final Price = Original Price - Discount Amount. You can also use the shortcut: Final Price = Original Price x (1 - Discount% / 100), which gives the same result in one step.
Q
How do I calculate the price after a discount?
Multiply the original price by (1 - discount rate). Example: $120 after 30% off = 120 x 0.70 = $84. This shortcut skips computing the discount amount separately and is the fastest method for mental math.
Q
Can I calculate stacked discounts?
This calculator handles one discount at a time. For stacked discounts, run the first calculation, then use the discounted price as the new original and apply the second percentage. Note: 20% off followed by 10% off is NOT the same as 30% off.
Q
Does this discount calculator include tax?
No - it shows the pre-tax discounted price. To add sales tax, take the final price from this tool and multiply by (1 + tax rate). For example, a $90 final price with 8% tax = 90 x 1.08 = $97.20.
Q
Is 50% off followed by another 50% off equal to free?
No. The second 50% discount applies to the already discounted price. For a $100 item, the first 50% off makes it $50. The second 50% off reduces it by $25, making the final price $25. This is a 75% total discount, not 100%.
Q
How do I calculate a 15% discount quickly?
Find 10% by moving the decimal point one place to the left. Then find 5% by halving that 10% amount. Add the two numbers together to get 15%. For example, on $60: 10% is $6. 5% is $3. So, 15% is $9.
Q
What is a good discount rate?
A 'good' discount rate depends on the industry. For retail clothing, 20-30% is common, while 50% or more indicates clearance. In electronics, margins are tighter, so a 10-15% discount can be considered significant.
Q
How do you reverse a discount?
To find the original price before a discount was applied, divide the final sale price by (1 - discount rate). For example, if you paid $80 after a 20% discount: $80 / (1 - 0.20) = $80 / 0.80 = $100 original price.

Expertise
Expert Notes
Financial experts recommend understanding the difference between margin and markup when applying discounts. A common pitfall for retailers is offering a discount that eats into their profit margin more significantly than anticipated. Always calculate your break-even point before heavily discounting merchandise. For consumers, it is crucial to remember that a discount is only valuable if the purchase was planned; spending money to "save" money still results in less cash on hand.
