1. What is a 20% Percentage Increase?

A 20% percentage increase means adding 20% of the original value to itself. This is commonly used in financial calculations, price adjustments, salary increases, and many other scenarios where a fixed percentage growth is applied.

2. How Does the Calculator Work?

The calculator uses the following simple formula:

Where:

• Old Value — The original amount before the increase
• 1.20 — Represents a 20% increase (100% + 20% = 120% = 1.20)

3. Practical Applications

Common Uses: This calculation is frequently used for:

• Calculating price increases (e.g., 20% markup on products)
• Determining salary raises (e.g., 20% pay increase)
• Investment growth projections
• Budget adjustments

4. Using the Calculator

Instructions: Simply enter the original value in the input field and click "Calculate" to see the new value after a 20% increase.

5. Frequently Asked Questions (FAQ)

Q1: How do I calculate a 20% increase manually?
A: Multiply the original value by 1.20 (which is the same as adding 20% of the original value to itself).

Q2: What if I want a different percentage increase?
A: The formula would be similar: New Value = Old Value × (1 + percentage/100). For example, for 15% it would be ×1.15.

Q3: Does this work for decreases too?
A: For decreases, you would multiply by (1 - percentage/100). For a 20% decrease, multiply by 0.80.

Q4: Can I use this for multiple percentage increases?
A: For consecutive increases, multiply by each factor. For two 20% increases: Old Value × 1.20 × 1.20 = Old Value × 1.44.

Q5: How is this different from compound interest?
A: A single percentage increase is simple multiplication. Compound interest applies the percentage increase repeatedly over time.
