# Percentage increase calculator

# percentage increase/decrease calculator:

**To calculate the percentage increase or decrease, you need to find the difference between the two values, divide it by the original value, and multiply by 100%. The formula is:**

Percentage change = ((new value – old value) / old value) x 100%

**Here’s an example:**

Suppose you earned $2,500 last month and $3,000 this month. What is the percentage increase in your earnings?

**Step 1:** Find the difference between the two values: $3,000 – $2,500 = $500.

**Step 2:** Divide the difference by the original value: $500 / $2,500 = 0.2.

**Step 3:** Multiply the quotient by 100% to express it as a percentage: 0.2 x 100% = 20%.

So the percentage increase in your earnings is 20%.

**Here’s the calculator:**

Input the old value: (e.g. 2500) Input the new value: (e.g. 3000)

Result: (percentage increase or decrease)

## step-by-step guide on how to calculate percentage increase or decrease:

To calculate the percentage increase or decrease, you need to find the difference between the two values, divide it by the original value, and multiply by 100%. The formula is:

Percentage change = ((new value – old value) / old value) x 100%

**Here’s an example:**

Suppose the price of a stock increased from $50 to $60. What is the percentage increase?

**Step 1:** Find the difference between the two values: $60 – $50 = $10.

**Step 2:** Divide the difference by the original value: $10 / $50 = 0.2.

**Step 3:** Multiply the quotient by 100% to express it as a percentage: 0.2 x 100% = 20%.

So the percentage increase is 20%.

**Here’s another example:**

Suppose the temperature dropped from 80 degrees Fahrenheit to 70 degrees Fahrenheit. What is the percentage decrease?

**Step 1:** Find the difference between the two values: 70 – 80 = -10.

**Step 2:** Divide the difference by the original value: -10 / 80 = -0.125.

**Step 3:** Multiply the quotient by 100% to express it as a percentage: -0.125 x 100% = -12.5%.

So the percentage decrease is 12.5%.
