How to Calculate Money in Percentage

The Basic Formula

The foundation for all percentage calculations is simple:

Percentage = (Part / Whole) x 100

Where:

• Part is the specific amount you're interested in.
• Whole is the total amount or reference value.

Let's apply this to some common financial scenarios.

Calculating a Percentage of a Sum

This is useful for understanding discounts, taxes, or portions of your income.

Example: What is 15% of $200?

1. Convert the percentage to a decimal: 15% = 0.15
2. Multiply the decimal by the whole amount: 0.15 x $200 = $30

Therefore, 15% of $200 is $30. You can easily solve this using our percentage calculator.

Determining What Percentage One Number Is of Another

This helps you understand ratios, such as expense ratios or return on investment.

Example: $30 is what percent of $150?

1. Divide the "part" by the "whole": $30 / $150 = 0.2
2. Multiply the result by 100: 0.2 x 100 = 20%

So, $30 is 20% of $150. Again, use our tool to quickly get the answer.

Calculating Percentage Increase or Decrease

This is crucial for tracking growth, inflation, or changes in investment value. This calculation is a percentage change.

Formula: [(New Value - Old Value) / Old Value] x 100

Example: An investment increased from $80 to $100. What's the percentage increase?

1. Find the difference: $100 - $80 = $20
2. Divide the difference by the original value: $20 / $80 = 0.25
3. Multiply by 100: 0.25 x 100 = 25%

The investment increased by 25%. Our calculator makes this even easier! There's a dedicated percentage change calculator as well!

Practical Applications & Examples

• Discounts: A shirt is 20% off its original price of $25. The discount is 0.20 x $25 = $5. The sale price is $25 - $5 = $20.
• Tips: You want to leave a 18% tip on a $45 restaurant bill. The tip amount is 0.18 x $45 = $8.10.
• Commissions: A salesperson earns a 5% commission on sales. If they sell $5,000 worth of goods, their commission is 0.05 x $5,000 = $250.
• Taxes: Sales tax is 7% on a $100 purchase. The tax amount is 0.07 x $100 = $7. The total cost is $100 + $7 = $107.

Tips and Tricks

• Estimate Quickly: To find 10% of a number, simply move the decimal point one place to the left (e.g., 10% of $120 is $12). You can then use this as a base for calculating other percentages (e.g., 20% is double 10%).
• Understanding Fractions: Familiarize yourself with common percentage-fraction equivalents (50% = 1/2, 25% = 1/4, 75% = 3/4, etc.).
• Use Online Tools: When accuracy is critical, leverage online percentage calculators to avoid manual calculation errors.
