What is Growth Rate?
Growth Rate represents the percentage change in a variable over a specific period of time. It is commonly used to measure changes in economic output, revenue, population, investment, or other key indicators.
Definition
Growth Rate is the rate at which a quantity increases or decreases over time, expressed as a percentage of its initial value.
Key Takeaways
- Growth rates measure change over time.
- Used across economics, finance, and business analysis.
- Can be positive (growth) or negative (decline).
Understanding Growth Rate
Growth rates help analysts understand trends, momentum, and performance. In economics, growth rates are used to assess GDP growth, inflation, employment changes, and productivity.
In business, growth rates track revenue, profit, customer acquisition, and market expansion. Comparing growth rates across periods or competitors provides insight into performance and strategic effectiveness.
Growth rates can be short-term (monthly, quarterly) or long-term (annual, compound). Context is critical, as high growth from a small base may not translate into sustained scale.
Formula (If Applicable)
Growth Rate (%) = ((Ending Value − Beginning Value) / Beginning Value) × 100
Real-World Example
If a company’s revenue increases from P2 million to P2.4 million in one year, the growth rate is:
((2.4 − 2.0) / 2.0) × 100 = 20%
