Estimate the change in unemployment implied by GDP growth. To use the Okun’s Law Calculator, enter gdp growth, potential growth, current unemployment; it returns change in unemployment, new unemployment rate, and shows them instantly as you type.
Where the Okun’s Law Calculator fits
Estimate the change in unemployment implied by GDP growth. The main figure it returns is the Change in unemployment, worked out from the values you enter.
It belongs with the other macroeconomics tools. If you are comparing options or checking a result from another angle, try the Fisher Effect Calculator, Phillips Curve Calculator or the Natural Rate of Unemployment Calculator.
How to use the Okun’s Law Calculator
- Fill in the fields. You will need GDP growth (%), Potential growth (%), Current unemployment (%). Use real figures from your own records where you can. Fields marked optional can stay at zero.
- Read the result. The highlighted box gives the Change in unemployment, and the cards below show New unemployment rate. Tables and charts break it down further.
- Test other scenarios. Results update as you type. Change one value at a time to see what drives the answer, and press Reset to go back to the defaults.
Formula and how it works
Example with real numbers
Here is the Okun’s Law Calculator using the default values shown in the calculator above:
Inputs
| GDP growth (%) | 1 |
|---|---|
| Potential growth (%) | 2 |
| Current unemployment (%) | 4.5 |
Results
| Change in unemployment | 0.5% |
|---|---|
| New unemployment rate | 5% |
With these inputs the calculator returns Change in unemployment: 0.5%. Change any value in the calculator to see how the result moves.
What if you change one input?
Sensitivity check: raising GDP growth (%) from 1 to 1.2 (about 20% higher) and leaving everything else as in the example above changes the results like this:
| Result | Example | After the change | Change |
|---|---|---|---|
| Change in unemployment | 0.5% | 0.4% | -20% |
| New unemployment rate | 5% | 4.9% | -2% |
The input that moves the result most is the one to check twice. Change it in the calculator above to test your own case.
What the results tell you

Frequently asked questions
What is Okun’s law?
An empirical link: faster growth than potential lowers unemployment.
Are these tools for students or professionals?
Both. They apply textbook formulas, so they suit coursework and quick policy or market checks.
What is the difference between nominal and real GDP?
Nominal GDP uses current prices; real GDP removes price changes using a deflator so output can be compared over time.
Are the results guaranteed?
No. Results depend entirely on the numbers you enter and the formulas shown on this page. Please do not make financial decisions based on them alone; confirm important figures with a licensed professional.
