Percentage Increase Calculator Guide

The percentage increase calculator computes how much a value grows from an original baseline to a new amount, or increases a base value by a specific percentage.

Mathematical Formulas

Mode 1: Percentage Increase Between Two Values

$\text{Percentage Increase} = \frac{V_2 - V_1}{V_1} \times 100\%$ Example: A price rises from $50 to$70: $\frac{70 - 50}{50} \times 100 = 40\% \text{ increase}$

Mode 2: Add a Percentage to a Number

$\text{Added Amount} = V_1 \times \left(\frac{P}{100}\right)$ $\text{Final Value} = V_1 + \text{Added Amount}$ Example: Add 15% to 80: $\text{Added} = 80 \times 0.15 = 12 \implies \text{Final} = 80 + 12 = 92$
