The Earnings Revision Ratio (ERR) is a widely used metric in financial analysis that evaluates the proportion of upward versus total analyst revisions for a company’s earnings estimates. It offers valuable insight into market sentiment and future performance expectations. If you’re an investor, analyst, or portfolio manager, understanding the ERR can give you a clearer view of stock momentum and valuation shifts.
In this guide, we’ll walk through what the earnings revision ratio is, how to calculate it, how to use our ERR calculator, and why it matters for equity research and investment decision-making.
Formula
The formula for calculating the Earnings Revision Ratio is:
Earnings Revision Ratio = Number of Upward Revisions ÷ (Upward Revisions + Downward Revisions)
Where:
- Upward Revisions refer to the number of times analysts increase their earnings estimates.
- Downward Revisions refer to the number of times analysts decrease their estimates.
The ratio ranges from 0 to 1, where a higher value indicates more optimism from analysts.
How to Use the Earnings Revision Ratio Calculator
Follow these steps:
- Enter Upward Revisions – Input the number of upward changes to earnings forecasts made by analysts.
- Enter Downward Revisions – Input the number of downward changes to earnings estimates.
- Click Calculate – The tool will show you the ERR as a decimal between 0 and 1.
For example, if there are 6 upward and 4 downward revisions:
ERR = 6 / (6 + 4) = 0.60
That means 60% of analyst revisions are positive, suggesting a bullish outlook.
Example Calculation
Let’s say a stock recently received:
- 8 upward earnings revisions
- 2 downward revisions
Using the formula:
ERR = 8 / (8 + 2) = 0.80
This means that 80% of all earnings revisions were positive. Investors would generally interpret this as a strong signal of confidence in the stock’s performance.

1. What is the Earnings Revision Ratio (ERR)?
ERR is a ratio that shows the proportion of positive (upward) earnings estimate revisions to total revisions.
2. Why is ERR important for investors?
It helps gauge analyst sentiment and is often a leading indicator of stock momentum and earnings surprises.
