Health & Diet
I weigh kg and I lost kg...
By what percentage did my weight decrease?
Type of calculation: Calculating percentage change (decrease).
Calculator usage: Before using the calculator, you must calculate the new weight (80 kg - 8 kg = 72 kg). Then use the Percentage Change CALCULATOR ("What is the percentage change from the Original value to the New value?"). Enter the original weight 80 [Original] and the new weight 72 [New]. The calculator will calculate the percentage decrease.
Explanation using a formula:
First, let's calculate the new weight after the weight loss:
New weight = Original weight - Weight lost
New weight = 80 kg - 8 kg = 72 kg
Now, we are looking for the percentage change from 80 kg to 72 kg.
Formula: ((New value - Original value) / Original value) × 100%
Percentage change = ((72 - 80) / 80) × 100% = (-8 / 80) × 100% = -0.1 × 100% = -10% (the minus sign indicates a decrease)
Alternative method (using the "Part-to-Whole Percentage CALCULATOR"): You can also calculate what percentage 8 kg (change) is of 80 kg (original weight). Use the Part-to-Whole Percentage CALCULATOR ("What percentage of Y is Z?"). Enter 80 [Y] and 8 [Z]. You will get 10%. Since the weight decreased, it is a 10% decrease.
Calculator usage: Before using the calculator, you must calculate the new weight (80 kg - 8 kg = 72 kg). Then use the Percentage Change CALCULATOR ("What is the percentage change from the Original value to the New value?"). Enter the original weight 80 [Original] and the new weight 72 [New]. The calculator will calculate the percentage decrease.
Explanation using a formula:
First, let's calculate the new weight after the weight loss:
New weight = Original weight - Weight lost
New weight = 80 kg - 8 kg = 72 kg
Now, we are looking for the percentage change from 80 kg to 72 kg.
Formula: ((New value - Original value) / Original value) × 100%
Percentage change = ((72 - 80) / 80) × 100% = (-8 / 80) × 100% = -0.1 × 100% = -10% (the minus sign indicates a decrease)
Alternative method (using the "Part-to-Whole Percentage CALCULATOR"): You can also calculate what percentage 8 kg (change) is of 80 kg (original weight). Use the Part-to-Whole Percentage CALCULATOR ("What percentage of Y is Z?"). Enter 80 [Y] and 8 [Z]. You will get 10%. Since the weight decreased, it is a 10% decrease.
Answer: Your weight decreased by %.

Shopping and Promotions
A product costs $ and has a % discount...
How much will I pay for it after applying the discount?
Type of calculation: Calculating the value after a percentage
decrease (discount).
Calculator usage:
Option 1 (Direct method): Use the Decreased Value CALCULATOR ("Calculate new value after percentage decrease"). Enter $250 [Original] and 20% [Decrease]. The calculator will directly give you the final price after discount.

Step 2: Subtract the discount amount calculated in Step 1 from the original price.
Explanation using a formula:
We are looking for the price after a 20% discount from $250.
Discount amount = 20% of $250
Discount amount = (20 / 100) × $250 = 0.2 × $250 = $50
Price after discount = $250 - $50 = $200
Alternative method: If the price is reduced by 20%, it means you will pay 100% - 20% = 80% of the original price. You can use the Basic Percentage CALCULATOR to directly calculate 80% of $250 (X=80, Y=250). (80/100)×250 = 0.8×250 = $200.
Calculator usage:

Discount amount = 20% of $250
Discount amount = (20 / 100) × $250 = 0.2 × $250 = $50
Price after discount = $250 - $50 = $200
Alternative method: If the price is reduced by 20%, it means you will pay 100% - 20% = 80% of the original price. You can use the Basic Percentage CALCULATOR to directly calculate 80% of $250 (X=80, Y=250). (80/100)×250 = 0.8×250 = $200.

Price of second product = 50% of 100
Price of second product = (50 / 100) × 100 = 0.5 × 100 = 50
Total price = Price of first product + Price of second product
Total price = 100 + 50 = 150
Calculator usage:
Step 1: Calculate the price of the second product. Use the Basic Percentage CALCULATOR ("What is X% of Y?"). The second product is 50% off, which means it costs 100% - 50% = 50% of the original price. Enter 50 [X] and 100 [Y]. The calculator will calculate 50% of 100.

Explanation using a formula:
We are looking for the total price for two products, where the first costs 100 and the second is 50% cheaper.
Price of second product = 50% of 100
Price of second product = (50 / 100) × 100 = 0.5 × 100 = 50
Total price = Price of first product + Price of second product
Total price = 100 + 50 = 150

Option 1 (Direct method): Use the Decreased Value CALCULATOR ("Calculate new value after percentage decrease"). Enter $80000 [Original] and 15% [Decrease]. The calculator will directly give you the car's value after one year.
Option 2 (Step-by-step method):
Step 1: Calculate the amount of depreciation. Use the Basic Percentage CALCULATOR ("What is X% of Y?"). Enter 15 [X] and $80000 [Y]. The calculator will calculate 15% of $80000.
Step 2: Subtract the depreciation amount calculated in Step 1 from the original car price.
Explanation using a formula:
We are looking for the car's value after one year, when it loses 15% of its value from $80000.
Depreciation = (15 / 100) × $80000 = 0.15 × $80000 = $12000
Value after one year = $80000 - $12000 = $68000
Answer: The car will be worth $ after one year.

By what percentage did the remuneration increase?
Type of calculation: Calculating percentage change (increase).
Calculator usage: Use the Percentage Change CALCULATOR ("What is the percentage change from the Original value to the New value?"). Enter 3000 [Original] and 3300 [New].
Explanation using a formula:
We are looking for the percentage change from $3000 to $3300.
Formula: ((New value - Original value) / Original value) × 100%
Percentage change = (($3300 - $3000) / $3000) × 100% = ($300 / $3000) × 100% = 0.1 × 100% = 10%
Calculator usage: Use the Percentage Change CALCULATOR ("What is the percentage change from the Original value to the New value?"). Enter 3000 [Original] and 3300 [New].
Explanation using a formula:
We are looking for the percentage change from $3000 to $3300.
Formula: ((New value - Original value) / Original value) × 100%
Percentage change = (($3300 - $3000) / $3000) × 100% = ($300 / $3000) × 100% = 0.1 × 100% = 10%

How many hours will I work now?
Type of calculation: Calculating the value after a percentage decrease.
Calculator usage:
Step 1: Calculate by how many hours the working time was reduced. Use the Basic Percentage CALCULATOR ("What is X% of Y?"). Enter 20 [X] and 40 [Y]. The calculator will calculate 20% of 40 hours.
Step 2: Subtract the number of hours calculated in Step 1 from the original number of hours.
Explanation using a formula:
We are looking for the number of working hours after a 20% reduction from 40 hours.
Reduction in working time = 20% of 40 hours
Reduction in working time = (20 / 100) × 40 hours = 0.2 × 40 hours = 8 hours
New working hours = Original working hours - Reduction in working time
New working hours = 40 hours - 8 hours = 32 hours
