What is Classic Percentage Increase?

Classic percentage increase is a fundamental mathematical concept that shows how much a value has grown relative to its original amount. It's called "classic" because it includes common, easily recognizable percentage increases that people frequently use in everyday situations.

This calculator focuses on common percentage increases like 50% (half again), 100% (double), and 200% (triple), making it particularly useful for quick mental math and common business scenarios.

How to Calculate Classic Percentage Increase

To calculate a classic percentage increase, follow these steps:

  1. Start with your original value
  2. Convert the percentage to a decimal (divide by 100)
  3. Add 1 to get the multiplier
  4. Multiply the original value by this number

For example, for a 50% increase:

  • 50% = 0.5
  • Multiplier = 1 + 0.5 = 1.5
  • If original value is 100: 100 × 1.5 = 150
Common Percentage Increases

50% Increase

A 50% increase means adding half of the original value. For example, increasing 100 by 50% results in 150 (original + half).

100% Increase

A 100% increase means doubling the original value. For example, increasing 100 by 100% results in 200 (twice the original).

200% Increase

A 200% increase means tripling the original value. For example, increasing 100 by 200% results in 300 (three times the original).

Applications and Examples

Business Growth

When a business doubles its revenue year-over-year, that's a 100% increase. If it triples, that's a 200% increase.

Investment Returns

An investment that grows by 50% means if you invested $1,000, you now have $1,500.

Population Growth

If a town's population doubles from 10,000 to 20,000, that's a 100% increase.

Retail Markup

A product that costs $40 to make and sells for $60 has a 50% markup.
