1. What is YoY Growth?

Year-over-year (YoY) growth is a key performance indicator that compares a company's current performance to the same period in the previous year. It measures the rate of growth over a 12-month period, providing insight into business trends and performance consistency.

2. How Does the Calculator Work?

The calculator uses the YoY growth formula:

\[ \text{YoY Growth} = \left( \frac{\text{Current Year} - \text{Previous Year}}{\text{Previous Year}} \right) \times 100\% \]

Where:

\( \text{Current Year} \) — Sales revenue for the current year period
\( \text{Previous Year} \) — Sales revenue for the same period in the previous year
\( 100\% \) — Conversion to percentage format

Explanation: This formula calculates the percentage change in sales from one year to the next, providing a clear measure of growth or decline.

3. Importance of YoY Growth Calculation

Details: YoY growth analysis helps businesses understand their performance trajectory, identify seasonal patterns, make informed strategic decisions, and benchmark against industry standards. It eliminates seasonal fluctuations that can distort month-to-month comparisons.

4. Using the Calculator

Tips: Enter current year sales and previous year sales in currency format. Both values must be positive, with previous year sales greater than zero to avoid division by zero errors.

5. Frequently Asked Questions (FAQ)

Q1: Why use YoY growth instead of month-over-month?
A: YoY growth eliminates seasonal variations and provides a more accurate picture of true business growth by comparing similar time periods.

Q2: What is considered good YoY growth?

Q3: Can YoY growth be negative?
A: Yes, negative YoY growth indicates that current year sales are lower than the previous year, representing a decline in business.

Q4: How often should YoY growth be calculated?
A: Typically calculated quarterly and annually, but can be measured for any consistent time period comparison.

Q5: What factors can affect YoY growth?
A: Market conditions, competition, economic factors, product launches, marketing efforts, and customer behavior changes can all impact YoY growth.
