Convert Percent Into a Decimal

When you need to convert percent into a decimal, you're essentially changing how a number is expressed. Percentages and decimals are two different ways to represent parts of a whole. A percentage shows parts per hundred, while a decimal expresses that same value as a number between 0 and 1 (or greater for values over 100%).

This conversion is fundamental in mathematics and appears frequently in real-world applications. From calculating sales tax to determining interest rates, understanding how to convert percentages into decimals is an invaluable skill.

Follow these simple steps to convert any percentage into a decimal:

1. Start with your percentage value - For example, 35%
2. Remove the percent sign - This gives you 35
3. Divide by 100 - 35 ÷ 100 = 0.35
4. The result is your decimal - 35% = 0.35

Alternatively, you can simply move the decimal point two places to the left. For 35%, imagine an invisible decimal point after the 5, then move it two positions left to get 0.35.

• 10% into decimal: 10 ÷ 100 = 0.10 or 0.1
• 33% into decimal: 33 ÷ 100 = 0.33
• 66% into decimal: 66 ÷ 100 = 0.66
• 100% into decimal: 100 ÷ 100 = 1.0
• 125% into decimal: 125 ÷ 100 = 1.25

Converting percent into a decimal is essential for financial calculations. When calculating compound interest, the formula requires the interest rate as a decimal. A 6% annual interest rate must be converted to 0.06 before using it in calculations. Similarly, when calculating discounts during sales, sales tax, or investment returns, decimal form is often required.
