Work out percentages, ratios, and percentage change.
Solve everyday percentage problems in one place: find X% of a number, work out what percentage one value is of another, and calculate percentage increase or decrease between two numbers.
Runs entirely in your browser — nothing is uploaded.
Subtract the old value from the new value, divide by the old value, and multiply by 100. The tool does this for you and shows whether it's an increase or decrease.
Mode one finds a percent of a number; mode two finds what percent one number is of another; mode three finds the percentage change between two numbers.
