# Percentage Calculator

This **Percentage Calculator** can help you calculate the percentages between two number values. Calculate percentages and unknowns using percent formulas. Solve the equations or add or subtract a percentage from a number.

## How to calculate Percentage?

**First Percentage Calculator:** What is percentage (p%) of x?

**Example: What is 3.63% of 463.26?**

**Step 1: Plug into formula**

y = (463.26 * 0.0363) / 100

**Step 2: Solve the multiplication in the numerator**

y = (16.816338) / 100

**Step 3: Solve the division to find y**

y = 0.16816338

**Second Percentage Calculator:** x is what percent of y?

**Example: 34 is what percent of 943.22?**

**Step 1: Plug into formula**

p = (34 * 100) / 943.22

**Step 2: Solve the multiplication in the numerator**

p = 3400 / 943.22

**Step 3: Solve the division to find p and add percent (%) at the end**

p = 3.60%

**Third Percentage Calculator:** x is p% of what?

**Example: 10 is 40% of what?**

**Step 1: Plug into formula**

y = (10 / 40) * 100

**Step 2: Solve the division**

y = 0.25 * 100

**Step 3: Solve the multiplication to find y**

y = 25

**Fourth Percentage Calculator:** What is x increased/decreased by p%?

**Example 1: What is 15 increased by 50%?**

**Step 1: Plug into formula**

**If x an increase of p%:** p% = (p% / 100) * 100. **If x a decrease of p%:** p% = -(p% / 100) * 100.

y = 15 * ((100 + 50) / 100)

**Step 2: Solve the addition in the numerator of the division**

y = 15 * (150 / 100)

**Step 3: Solve the division**

y = 15 * 1.5

**Step 4: Solve the multiplication to find y**

y = 22.5

**Example 2: What is 24.34 decreased by 26.7%?**

**Step 1: Plug into formula**

**If x an increase of p%:** p% = (p% / 100) * 100. **If x a decrease of p%:** p% = -(p% / 100) * 100.

y = 24.34 * ((100 - 26.7) / 100)

**Step 2: Solve the addition in the numerator of the division**

y = 24.34 * (73.3 / 100)

**Step 3: Solve the division**

y = 24.34 * 0.733

**Step 4: Solve the multiplication to find y**

y = 17.84122
