FAQs

How does the year over year growth calculator work?

Enter the requested values to receive a deterministic result. No live market, tax, or jurisdiction data is inferred.

Use Cases

Track business performance

Use the calculator to compare annual revenue, profit, or other key metrics to assess whether your business is growing or shrinking year over year.

Example: Compare 2023 revenue of $120,000 to 2022 revenue of $100,000 to see a 20% growth.

Analyze investment returns

Investors can use YoY growth to evaluate the performance of stocks, funds, or other assets by comparing their values from one year to the next.

Example: If a stock was worth $50 last year and $60 now, the YoY growth is 20%.

Frequently Asked Questions

What is year-over-year growth?: Year-over-year (YoY) growth compares a metric (like revenue or profit) in one period to the same period in the previous year. It shows the absolute change and the percentage change, helping you understand trends and performance over time.
How do I calculate year-over-year growth?: To calculate YoY growth, subtract the previous year's value from the current year's value to get the absolute growth. Then divide that difference by the previous year's value and multiply by 100 to get the percentage growth. This calculator does it for you.
Can this calculator handle negative growth?: Yes, the calculator can handle negative growth. If the current year's value is less than the previous year's, the absolute growth will be negative, and the percentage growth will also be negative, indicating a decline.

Tips & Common Mistakes

Tips

Ensure you use the same time period for both years (e.g., full year to full year) to get an accurate comparison.
Use consistent units (e.g., dollars, euros) for both values to avoid calculation errors.
For a clearer picture, calculate YoY growth for multiple consecutive years to identify trends.
Remember that percentage growth can be misleading if the base value is very small or very large; consider absolute growth as well.

Common Mistakes to Avoid

Using different time periods for the two years, such as comparing a full year to a partial year.
Forgetting to subtract the previous year's value from the current year's value before dividing.
Misinterpreting negative growth as a calculation error when it actually indicates a decline.
