Example
A $250 phone gets a price increase of 8%. What is the new price?
Vf = 250 × (1 + 8/100) = 250 × 1.08 = 270
The new price is $270.
Example
Monthly rent goes from $1,200 to a new rate 3.5% higher. What is the new rent?
Vf = 1200 × (1 + 3.5/100) = 1200 × 1.035 = 1242
The new rent is $1,242.
Example
A town of 5,000 people grows by 12% over five years. What is the new population?
Vf = 5000 × (1 + 12/100) = 5000 × 1.12 = 5600
The new population is 5,600.
When to use this calculator
Use this when you know the starting value and the percentage increase, and want the new value. If instead you know both the starting and ending values and want to find the percentage between them, use the percentage change calculator instead.
Frequently asked questions
Can the percentage increase be more than 100%?
Yes. A 150% increase on 100 gives 100 × (1 + 150/100) = 250, more than double the original value.
Does this work if the starting value is negative?
The formula still applies, but the result can be counter-intuitive with negative numbers. See the percentage change for negative numbers calculator for that case.
How is this different from the percentage decrease calculator?
This calculator adds a percentage to a value. For subtracting a percentage, use the percentage decrease calculator. Related: percentage decrease calculator and full formula guide.
