How do I calculate a percentage of a number?

To calculate a percentage of a number, multiply the number by the percentage and divide by 100. For example, 15% of 200 is (200 × 15) / 100 = 30. This calculator handles it automatically — enter the number and the percentage, and the result appears instantly. You can also calculate percentage change, reverse percentages, and what percentage one number is of another.

How do I use the percentage increase calculator?

Enter the original value and the new value, then select "Percentage Change". The calculator computes the increase as ((new - original) / original) × 100. For example, if a price goes from $80 to $100, the percentage increase is 25%. If the new value is lower than the original, the result shows a percentage decrease instead. The calculator handles negative original values correctly using the absolute value in the denominator.

How do I calculate percentage decrease?

Enter the original value and the new (lower) value, then select "Percentage Change". The decrease is calculated as ((original - new) / original) × 100. For example, if a price drops from $200 to $150, the percentage decrease is 25%. The calculator automatically determines whether the change is an increase or decrease based on which value is larger.

How do I calculate percentage difference?

Use the percentage difference when comparing two values without a clear "original" and "new" — the formula averages both values as the base. Percentage difference = |value1 - value2| / ((value1 + value2) / 2) × 100. For example, if one item costs $40 and another costs $60, the percentage difference is 40%. This is different from percentage change, which uses one value as the baseline.

How do I calculate improvement percentage?

Enter the before value as the original and the after value as the new value, then select "Percentage Change". For example, if your test score improved from 70 to 85, the improvement percentage is ((85 - 70) / 70) × 100 = 21.4%. This works for any before-and-after comparison: weight loss, performance metrics, production output, or any measurable improvement.

How do I calculate a percentage increase when the original number is negative?

Percentage change with a negative base is a common source of confusion. If revenue goes from -50 to +50, the formula gives (50 - (-50)) / |-50| × 100 = 200%. But if revenue goes from -50 to -25, the formula gives (-25 - (-50)) / |-50| × 100 = 50% — a 50% improvement even though the number is still negative. Always use the absolute value of the original number as the denominator to avoid sign errors.

What is the difference between percentage points and percent change?

Percentage points measure the absolute difference between two percentages. If an interest rate rises from 5% to 7%, that is a 2 percentage point increase — but a 40% relative increase (because 2 is 40% of 5). Financial news often confuses these: "rates rose by 2%" could mean either 2 percentage points (5% to 7%) or a 2% relative increase (5% to 5.1%). The Percentage Change mode on this calculator computes the relative change; use the Difference mode for percentage point comparisons.

How do I calculate reverse percentage — finding the original price before a discount?

If an item costs $80 after a 20% discount, the original price was not $96 (a common mistake). The $80 represents 80% of the original, so the original is $80 / 0.80 = $100. Use the "Reverse Percentage" mode: enter 80 as the final value and 20 as the discount percentage, and the calculator returns the original price of $100.

How to find the percentage of a number?

Use the "Find Percentage" mode. Enter the part (smaller number) and the whole (larger number). For example, to find what percentage 25 is of 200, enter Part: 25 and Whole: 200. The calculator will show 12.5%.

What percentage calculations are available?

The percentage calculator handles six common calculations: percentage of a number, percentage change (increase/decrease), what percentage one number is of another, reverse percentage, adding a percentage to a number, and subtracting a percentage.

Why was the Meitei script replaced by Bengali script?

In the 18th century, the Kingdom of Manipur adopted Bengali script under the influence of Hinduism, specifically Vaishnavism. The traditional Meitei script (Meetei Mayek) fell out of official use for nearly two centuries. A revival movement began in the 20th century, and the script was added to Unicode in 2009. Today it is taught in Manipuri schools and used in cultural publications, though Bengali script remains common for everyday writing.

Input: What is 15% of 250?

Result: 15% of 250 = 0.15 × 250 = 37.5

Input: Percentage change from 80 to 100

Result: Change = ((100 − 80) / 80) × 100 = 25% increase
