Understanding Percentages
A percentage represents a fraction of 100. It is used to compare values, express growth or decline, and analyze proportions. The basic percentage formula is:
P=(XY)×100P = \left( \frac{X}{Y} \right) \times 100
Where:
- P is the percentage
- X is the part or value
- Y is the total or whole
This formula forms the foundation for various advanced percentage calculations.
Key Functions of an Advanced Percentage Calculator
An advanced percentage calculator goes beyond basic percentage finding. It can:
✅ Find the percentage of a number – Useful for calculating discounts, tax, or tips.
✅ Determine the total value – Helps in finding the original amount before applying a percentage.
✅ Increase or decrease a value by a percentage – Useful for inflation rates, salary hikes, or depreciation.
✅ Find percentage difference – Important for analyzing changes between two values.
✅ Solve percentage equations – Used in finance, statistics, and everyday budgeting.
Common Percentage Calculations and Formulas
1. Finding a Percentage of a Number
To calculate what percentage X is of Y, use:
P=(XY)×100P = \left( \frac{X}{Y} \right) \times 100
Example: If a student scores 45 marks out of 60, their percentage is:
(4560)×100=75%\left( \frac{45}{60} \right) \times 100 = 75\%
2. Calculating a Value from a Percentage
To find the value when given a percentage, use:
X=(P100)×YX = \left( \frac{P}{100} \right) \times Y
Example: What is 20% of 150?
X=(20100)×150=30X = \left( \frac{20}{100} \right) \times 150 = 30
3. Finding the Total from a Percentage
To find the total when given a percentage and a part, use:
Y=X×100PY = \frac{X \times 100}{P}
Example: If 40 is 25% of a total, the total is:
Y=40×10025=160Y = \frac{40 \times 100}{25} = 160
4. Percentage Increase or Decrease
To increase a number Y by P%, use:
New Value=Y+(P100×Y)New\ Value = Y + \left( \frac{P}{100} \times Y \right)
To decrease a number Y by P%, use:
New Value=Y−(P100×Y)New\ Value = Y – \left( \frac{P}{100} \times Y \right)
Example: If a product costing $200 is discounted by 15%, the new price is:
200−(15100×200)=200−30=170200 – \left( \frac{15}{100} \times 200 \right) = 200 – 30 = 170
5. Percentage Difference Between Two Values
To find the percentage change between two numbers A and B, use:
