To find attributable risk, subtract the incidence rate in the unexposed group from the incidence rate in the exposed group.

AR = Ie – Iu

| AR | Attributable Risk |
| Ie | Incidence in Exposed Group |
| Iu | Incidence in Unexposed Group |
What is an Attributable Risk Calculator | Find The Risk Factor While Doing Something Harmful To General Health:
Imagine two groups of people—one that smokes, and one that doesn’t. Over time, some in each group develop lung disease. The Attributable Risk Calculator helps you figure out how much of the disease risk is due to smoking itself. It shows the extra risk caused by the exposure.
This tool is commonly used in epidemiology, health research, and risk analysis. If you're studying how one factor (like smoking, pollution, or diet) impacts a specific outcome, this calculator gives you the risk difference between the exposed and unexposed groups. You’ll also find more advanced versions, like the population attributable risk calculator, or tools for SPSS and Excel users.
It works well with related terms like attributable risk percentage, relative risk calculator, and how to calculate risk exposure value. If you’re comparing attributable risk vs. relative risk, or trying to understand the impact of a health behavior, this calculator gives you a clear, simple number that makes risk easier to measure—and to manage.
