Raw numbers don't always tell the full story. If a company's revenue goes up by $10,000, that sounds great! But if they are a billion-dollar company, that increase is statistically zero. Calculating the percentage increase gives you the true context of growth.
The Formula, With a Worked Example
Percentage increase is ((New Value − Old Value) ÷ Old Value) × 100. For example, going from 100 to 150: the difference is 50, and 50 ÷ 100 = 0.5, so multiplying by 100 gives a 50% increase — the same result as the $1,000-to-$1,500 revenue example above, just scaled down.
Perfect for Salary Negotiations
If you are asking for a raise, or evaluating a new job offer, knowing the exact percentage increase of your salary is a crucial negotiating tactic. Simply enter your current salary as the "From" value and the proposed salary as the "To" value.
Frequently Asked Questions
First, find the difference between the two numbers (New Value - Old Value). Then, divide that difference by the Old Value. Finally, multiply by 100 to get the percentage.
It is most commonly used in business to track growth. For example, if you made $1,000 last month and $1,500 this month, you had a 50% revenue increase.
Yes! If a value doubles, that is a 100% increase. If it triples, that is a 200% increase.
The calculator divides by the absolute value of the original number, so the percentage change still reads correctly even when the starting value is negative, such as a swing from a loss to a profit.
No. Percentage points measure the raw gap between two percentages (going from 40% to 50% is a 10 percentage point increase), while percentage increase measures relative growth (that same move is a 25% increase).
They use the identical formula. This page is framed around growth — revenue, salary, or metrics going up — while the Percentage Decrease Calculator is framed around values going down. Enter your two numbers either way and the result tells you which one you're looking at.
Multiply the original value by 1.5. For example, a 50% increase on 100 is 100 x 1.5 = 150.
