How much will I spend this year?
Type of calculation: Calculating the value after a percentage increase.
Calculator usage:
Step 1: Calculate the expense increase amount. Use the Basic Percentage CALCULATOR ("What is X% of Y?"). Enter the percentage increase as X (8) and last year's expenses as Y ($500). The calculator will calculate 8% of $500.
Step 2: Add the increase amount calculated in Step 1 to last year's expenses.
Explanation using a formula:
We are looking for this year's expense amount after an 8% increase from $500.
Amount of increase = (8 / 100) × $500 = 0.08 × $500 = $40
Expenses this year = $500 + $40 = $540

How many watts does an LED bulb consume?
Type of calculation: Calculating the value after a percentage decrease.
Calculator usage:
Step 1: Calculate how much less energy the LED bulb consumes. Use the Basic Percentage CALCULATOR ("What is X% of Y?"). Enter the percentage of lower consumption as X (80) and the power consumption of the traditional bulb as Y (60). The calculator will calculate 80% of 60 W.
Step 2: Subtract the value calculated in Step 1 from the power consumption of the traditional bulb.
Explanation using a formula:
We are looking for the power consumption of the LED bulb, which uses 80% less than a 60 W bulb.
Reduction in consumption = 80% of 60 W
Reduction in consumption = (80 / 100) * 60 W = 0.8 * 60 W = 48 W
LED power consumption = Traditional power consumption - Reduction in consumption
LED power consumption = 60 W - 48 W = 12 W
Calculator usage:
Step 1: Calculate how much less energy the LED bulb consumes. Use the Basic Percentage CALCULATOR ("What is X% of Y?"). Enter the percentage of lower consumption as X (80) and the power consumption of the traditional bulb as Y (60). The calculator will calculate 80% of 60 W.
Step 2: Subtract the value calculated in Step 1 from the power consumption of the traditional bulb.
Explanation using a formula:
We are looking for the power consumption of the LED bulb, which uses 80% less than a 60 W bulb.
Reduction in consumption = 80% of 60 W
Reduction in consumption = (80 / 100) * 60 W = 0.8 * 60 W = 48 W
LED power consumption = Traditional power consumption - Reduction in consumption

Health and 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 as "Original" (80) and the new weight as "New" (72). 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 as Y and 8 as 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 as "Original" (80) and the new weight as "New" (72). 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 as Y and 8 as Z. You will get 10%. Since the weight decreased, it is a 10% decrease.
Answer: Your weight decreased by %.

What will be the total amount including interest?
Type of calculation: Calculating compound interest.
Calculator usage: Since there isn't a dedicated "Compound Interest CALCULATOR" in our list, you should use a scientific or financial calculator, entering the values into the compound interest formula. You can also use a spreadsheet program (e.g., Excel, Google Sheets) and the FV (Future Value) function.
Explanation using a formula:
We are looking for the final amount after 3 years with annual compounding.
General formula for compound interest: A = P * (1 + r/n)^(n*t)
Given:
A = $1000 * (1 + 0.05/1)^(1*3)
A = $1000 * (1 + 0.05)^3
A = $1000 * (1.05)^3
A = $1000 * 1.157625
A = $1157.63
Calculating the interest earned: Interest = A - P = $1157.63 - $1000 = $157.63

- r = 5% = 0.05
- t = 3 years
- n = 1 (annual compounding)
A = $1000 * (1 + 0.05/1)^(1*3)
A = $1000 * (1 + 0.05)^3
A = $1000 * (1.05)^3
A = $1000 * 1.157625
A = $1157.63
Calculating the interest earned: Interest = A - P = $1157.63 - $1000 = $157.63
Answer: After 3 years, the total amount on the deposit will be $ . The interest earned will be $ .

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:
Step 1: Calculate the discount amount. Use the Basic Percentage CALCULATOR ("What is X% of Y?"). Enter the discount percentage as X (20) and the original price as Y (250). The calculator will calculate 20% of $250.
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:
Step 1: Calculate the discount amount. Use the Basic Percentage CALCULATOR ("What is X% of Y?"). Enter the discount percentage as X (20) and the original price as Y (250). The calculator will calculate 20% of $250.
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.

My working hours were reduced by %. If I previously worked hours a week...
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 the reduction percentage as X (20) and the original number of hours as Y (40). 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
