1. What is a YoY Growth Calculator?

Definition: This calculator measures the year-over-year growth percentage between two values.

Purpose: It helps business analysts, investors, and managers track performance changes between comparable periods.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Current — The most recent value
• Previous — The value from the previous comparable period

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

3. Importance of YoY Growth Calculation

Details: YoY growth eliminates seasonal fluctuations, providing a clearer picture of true business performance trends.

4. Using the Calculator

Tips: Enter the current period value and previous period value. The previous value cannot be zero.

5. Frequently Asked Questions (FAQ)

Q1: What does negative YoY growth indicate?
A: Negative growth means the current value is less than the previous period's value, indicating declining performance.

Q2: How is YoY different from QoQ?
A: YoY compares annual periods, while QoQ (Quarter-over-Quarter) compares consecutive quarters.

Q3: What if my previous value was zero?
A: YoY cannot be calculated when the previous value is zero as it would require division by zero.

Q4: What units should I use?
A: The calculator works with any consistent units (dollars, units sold, etc.) as long as both values use the same unit.

Q5: How precise should my inputs be?
A: Use the same precision as your source data. The calculator handles up to 2 decimal places in the result.
