1. What is a Percentage Growth Rate Calculator?

Definition: This calculator measures the percentage change between an old value and a new value.

Purpose: It helps analyze growth trends in business metrics, investments, population studies, and other quantitative fields.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \%GR = \frac{V_{new} - V_{old}}{V_{old}} \times 100 \]

Where:

\( \%GR \) — Percentage growth rate
\( V_{new} \) — New measurement or value
\( V_{old} \) — Original or previous value

Explanation: The difference between new and old values is divided by the old value to get relative change, then multiplied by 100 to convert to percentage.

3. Importance of Growth Rate Calculation

Details: Growth rate analysis helps track performance, make projections, and compare different metrics over time.

4. Using the Calculator

Tips: Enter the old value (baseline) and new value (current measurement). The old value cannot be zero.

5. Frequently Asked Questions (FAQ)

Q1: What does a negative growth rate mean?
A: A negative percentage indicates decline or reduction rather than growth.

Q2: Can I compare growth rates of different scales?
A: Yes, percentages allow comparison between metrics of different magnitudes.

Q3: What if my old value is zero?
A: Growth rate is undefined when starting from zero. Consider absolute change instead.

Q4: How often should I calculate growth rates?
A: Frequency depends on your needs - daily for stocks, monthly for business metrics, annually for populations.

Q5: What's considered a "good" growth rate?
A: This varies by industry and context. Compare to historical rates or industry benchmarks.
