Percentage Increase Calculator
Enter the original value and the new value to see the percentage increase instantly — no formula needed. Used for checking pay rises, measuring revenue growth, tracking price increases, or comparing any two numbers where one is larger than the other. A common mistake is confusing percentage points with percentage change: if interest rates go from 2% to 3%, that is a 1 percentage-point rise but a 50% percentage increase. To work in the opposite direction — entering a percentage to find a new value — use the salary increase calculator or the percentage of a number calculator.
When to use this calculator
Use this when a value has gone up and you need to express the growth as a percentage — a salary rising from $45,000 to $51,750, revenue climbing from $80,000 to $96,000, a product price going from $12 to $15, or a test score improving from 64 to 80.

FAQ
How do I figure out the percentage increase between two numbers?
Subtract the original from the new value to get the change. Divide that change by the original, then multiply by 100. For example, from 80 to 100: (100 − 80) ÷ 80 × 100 = 25%. Enter the two numbers above and the result appears instantly.
What is the percentage increase from 80 to 100?
The percentage increase from 80 to 100 is 25%. Calculation: (100 − 80) ÷ 80 × 100 = 25%.
What is the percentage increase from 50 to 75?
The percentage increase from 50 to 75 is 50%. Calculation: (75 − 50) ÷ 50 × 100 = 50%.
How do I calculate a price increase as a percentage?
Use the same formula: (New Price − Old Price) ÷ Old Price × 100. For example, a product going from $40 to $52 is a 30% price increase. This applies to supplier quotes, rent increases, subscription renewals, or any cost that has gone up.
How do I calculate a salary increase as a percentage?
Divide the raise amount by the original salary and multiply by 100. If your salary goes from $52,000 to $56,160, that's ($56,160 − $52,000) ÷ $52,000 × 100 = 8% increase. Use the salary increase calculator if you want to work from the percentage and find the new salary instead.
Can the result be more than 100%?
Yes. If a value doubles, the percentage increase is 100%. If it triples, the increase is 200%. Prices, traffic, and subscriber counts can all grow beyond 100% of the original value.
What if my new value is lower than the original?
The result will be negative, meaning the value fell rather than rose. If you're specifically measuring a drop, the percentage decrease calculator is more explicit about direction.
What is the difference between percentage increase and percentage points?
These are frequently confused. If a rate goes from 4% to 6%, that is a 2 percentage-point increase — but it is a 50% percentage increase (because 6 is 50% more than 4). Percentage points measure the absolute difference; percentage increase measures the relative change.
How does percentage increase relate to ROI?
Return on investment is the same calculation applied to money. If you invested $500 and it grew to $700, the ROI calculator returns 40% — identical to the percentage increase formula, just labelled differently.
