Subtracting a percentage from a number is a simple process that helps you find the reduced value. Let's learn how to do it step by step!
When you subtract a percentage from a number, you are reducing that number by a certain portion of itself. It's like applying a discount to a price!
To begin, you'll need two things: the original number and the percentage you want to subtract. For example:
To work with percentages in calculations, convert the percentage to a decimal by dividing by 100:
Decimal = Percentage / 100
In this example: Decimal = 15 / 100 = 0.15
Now, multiply the original number by the decimal to find the amount to subtract:
Amount to Subtract = Original Number × Decimal
In our example: Amount to Subtract = 200 × 0.15 = 30
Finally, subtract the calculated amount from the original number to find the new, reduced value:
New Value = Original Number - Amount to Subtract
In this case: New Value = 200 - 30 = 170
Formula is =A2-(A2*B2/100), where A2 is the number, and B2 is the percentage.
In this video, we show how to calculate the discounted price in Excel by subtracting a percentage from the original price.
Scenario: A product costs $100, and you get a 20% discount.
Calculation: Subtract 20% from $100.
$100 × 0.20 = $20 (Amount to Subtract)
$100 - $20 = $80 (Discounted Price)
Result: After a 20% discount, the final price is $80.
Scenario: A car that originally costs $25,000 is on sale with a 15% price reduction.
Calculation: Subtract 15% from $25,000.
$25,000 × 0.15 = $3,750 (Amount to Subtract)
$25,000 - $3,750 = $21,250 (Reduced Price)
Result: After a 15% price reduction, the car costs $21,250.
Scenario: Your annual salary of $50,000 is reduced by 10% due to company cutbacks.
Calculation: Subtract 10% from $50,000.
$50,000 × 0.10 = $5,000 (Amount to Subtract)
$50,000 - $5,000 = $45,000 (New Salary)
Result: After the deduction, your new annual salary is $45,000.
Scenario: You weighed 80 kg and lost 5% of your body weight through a fitness program.
Calculation: Subtract 5% from 80 kg.
80 × 0.05 = 4 kg (Amount to Subtract)
80 - 4 = 76 kg (New Weight)
Result: After losing 5%, your new weight is 76 kg.
Scenario: A laptop worth $1,200 depreciates by 25% after one year.
Calculation: Subtract 25% from $1,200.
$1,200 × 0.25 = $300 (Amount to Subtract)
$1,200 - $300 = $900 (Depreciated Value)
Result: After depreciation, the laptop is worth $900.
