What Is the Percentage Increase?
Percentage increase is a relative growth that compares the increase in a value with the original value. It is can be calculated by the following formula:
Percent Increase = (New Original) ÷ Original × 100%
In everyday terms, it shows how much bigger something got, relative to where it started
How This Calculator Works
- Enter the original value (starting number)
- Enter the new value (higher or lower)
- Click “Calculate Increase”
- Shows the percent increase
- If the value dropped, it displays a percentage decrease
- Shows the percent increase
- Hit “Clear” to reset and reuse
The tool checks:
- Original must be greater than 0
- Both inputs must be valid numbers
Why It’s Useful
- Track price changes: from $25 → $30 = 20% increase
- Analyze grades: 75 → 82 = ~9.33% increase
- Monitor sales growth: 200 → 250 = 25% increase
- Spot decreases: tells you when values drop, telling the percent decrease
Why Base Value Matters
Every percentage change references the original value. A $10 increase off $100 is 10%, but the same $10 off $200 is just 5%. Always compare to what you started with.
Common Misunderstandings
- Percent points vs percent increase: A rise from 40% to 44%? That’s +4 percentage points, but a 10% increase in the value.
- Not symmetric: +10% increase followed by -10% drop doesn’t return you to the original. Because 10% of a higher number is more .
Why This Calculator Stands Out
- Simple: Clean UI, zero distractions
- Mobile‑friendly: Buttons stay clickable on any device
- Value‑checked: Alerts prevent invalid inputs
- Flexible: Detects increases, decreases, or no change
- Private: Everything runs in your browser no data saved
Tips for Smart Use
- Use it to compare deals or track progress
- For multiple changes, calculate each separately and then average
- Put it on your bookmark bar for quick access
- Combine with a companion percentage decrease tool for full coverage
