How to convert PERCENT to DECIMAL
Percent values need to be in decimal form for use in arithmetic, spreadsheet formulas, and code. A tax rate of 23%, a loan interest rate of 6.5%, or a discount of 15% must be written as 0.23, 0.065, or 0.15 respectively before you can multiply them against a base amount. The conversion is simply dividing by 100.

Enter the percentage
Type the percent value without the % sign. For example, type 23 for 23%, or 6.5 for 6.5%.
Read the decimal result
The converter divides by 100 and shows the decimal. 23% = 0.23; 6.5% = 0.065; 100% = 1.0.
Use the decimal in your calculation
Multiply the decimal by your base amount: 0.23 x 1000 = 230 (tax on a 1000 item at 23%).
Convert back if needed
Switch to decimal-to-percent if you have a decimal rate and need the percentage.
