How It Works

Percentage increase is calculated using the formula: (new − original) ÷ original × 100. The calculator subtracts the original value from the new value to find the amount of increase. That increase is then divided by the original value to express it as a proportion of the starting point, and multiplying by 100 converts it to a percentage. The raw increase amount is displayed alongside the percentage so you can see both the relative and absolute change. If the new value is lower than the original, the formula produces a negative result, indicating a decrease rather than an increase — in that case, the Percentage Decrease Calculator provides clearer framing for the result.

Examples

Price Increase
A product increases from $100 to $120.
Result: 20% increase, a rise of $20.
Salary Raise
Annual salary grows from $55,000 to $62,500.
Result: Approximately 13.64% increase, a raise of $7,500.
Subscriber Growth
A channel grows from 8,000 to 12,000 subscribers.
Result: 50% increase, an addition of 4,000 subscribers.

Frequently Asked Questions

How do you calculate percentage increase?
Subtract the original value from the new value to get the increase amount. Then divide that amount by the original value and multiply by 100. For example, an increase from 50 to 75 is a gain of 25, divided by 50, multiplied by 100, giving 50%.
What is a percentage increase used for?
Percentage increase is used in countless situations: measuring investment returns, comparing salary offers, tracking business revenue growth, analysing inflation, and monitoring fitness or health improvements over time.
Can a percentage increase be over 100%?
Yes. A 100% increase means the value doubled. A 200% increase means it tripled. There is no upper limit — values can increase by any amount, and the percentage will reflect it accurately.
