Formula Refresher
Percent Increase
((New − Original) ÷ Original) × 100. Positive results indicate growth.
Absolute Increase
New − Original. The raw gain in dollars, units, or any measurement you’re tracking.
New Total
The final value after the increase. Useful for forecasting or budgets.
Interpretation
Negative results represent a decrease; you can still use this calculator to spot declines.
Example Increases
| Original | New | Absolute Increase | % Increase | Scenario |
|---|---|---|---|---|
| $50 | $75 | $25 | 50% | Retail price adjustment |
| 1,000 users | 1,250 users | 250 | 25% | App user growth |
| 80 points | 96 points | 16 | 20% | Exam score improvement |
| $5,000 | $6,500 | $1,500 | 30% | Revenue increase |
Tips for Reporting Growth
- List both dollar and percent changes. Executives love to see the raw amount and the context.
- Note the time period. “+12% month-over-month” reads very differently from “+12% year-over-year.”
- Use negative values where needed. If performance slipped, the calculator shows a negative percent to highlight the loss.
- Explain the driver. Pair your calculation with a sentence or two about what caused the increase.
Frequently Asked Questions
Absolutely. A 100% increase means the new value doubled. A 250% increase means it’s 3.5× the original value.
A negative output indicates a percentage decrease. That simply means the new value is below the original.
Divide the new value by (1 + percent as a decimal). Example: $120 after a 20% increase → 120 ÷ 1.2 = $100 original.
