Use the 3 percentage increase calculators below: find the percentage change between two values (with automatic increase or decrease detection), calculate the final value after an increase, or find the original value before an increase was applied.
Percentage Increase Calculator
Calculation 1 — Increase or decrease between two values
Calculation 2 — Final value after a percentage increase
Calculation 3 — Original value before a percentage increase
How to use the percentage increase calculator
- Calculation 1: Enter the initial and final values. The calculator automatically detects whether there was an increase or decrease, and shows the percentage and the absolute difference.
- Calculation 2: Enter the initial value and the percentage increase to get the final value.
- Calculation 3: Know the final value and the percentage increase that was applied? Find the original value.
Formulas
| Calculation | Formula |
|---|---|
| % increase | % = 100 × (Vf − Vi) ÷ |Vi| |
| Final value | Vf = Vi × (1 + % ÷ 100) |
| Original value | Vi = Vf ÷ (1 + % ÷ 100) |
Frequently asked questions
How do you calculate the percentage increase between two values?
Use: % = 100 × (final − initial) ÷ |initial|
Example: from 12 to 23: % = 100 × (23 − 12) ÷ 12 = 100 × 11 ÷ 12 = 91.67%
Are percentage increase and percentage change the same thing?
Yes, the formula is identical: ((final − initial) / initial) × 100. The difference is only in context: percentage increase is the term used when the final value is greater than the initial (positive result). When the result is negative, we have a percentage decrease.
How do you find the original value before the increase?
Use: Vi = Vf ÷ (1 + % ÷ 100)
Example: after a 25% increase the price became $125. Original value = 125 ÷ 1.25 = $100.00
Do two consecutive 10% increases add up to 20% total?
No. Two 10% increases each result in 21% total: (1.10 × 1.10 − 1) × 100 = 21%. This happens because the second increase applies to a larger base than the original.
Practical examples
| Situation | Initial | Final | Increase |
|---|---|---|---|
| Salary raise | $3,000 | $3,300 | 10% |
| Property price rise | $400,000 | $480,000 | 20% |
| Follower growth | 5,000 | 6,750 | 35% |
| Electricity bill increase | $180 | $207 | 15% |
