Percentage Increase Calculator
Calculate the result of increasing a value by a given percentage.
The Percentage Increase Calculator computes what a value becomes after applying a percentage increase. Enter the original value and the percentage to add, and the tool returns both the new total and the amount of the increase itself.
This is one of the most frequently needed everyday calculations. Retailers use it to mark up wholesale prices. Employers use it to compute salary raises. Landlords use it to apply annual rent increases. Investors use it to project growth rates on principal amounts.
The formula is straightforward: the increased value equals the original value multiplied by one plus the percentage divided by 100. The increase amount is simply the original value multiplied by the percentage divided by 100. Despite the simplicity of the formula, having a dedicated calculator eliminates mental math errors and saves time when you need to run the numbers quickly.
