What is the Gini Coefficient Calculator?
Measure income inequality from a list of incomes. To use the Gini Coefficient Calculator, enter incomes; it returns gini coefficient, mean income, count, and shows them instantly as you type.
Where the Gini Coefficient Calculator fits
Measure income inequality from a list of incomes. The main figure it returns is the Gini coefficient, 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 Price Elasticity of Supply Calculator, Buying Power Calculator or the Private Savings Calculator.
How to use the Gini Coefficient Calculator
- Enter your numbers. The inputs are Incomes (comma separated). 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 Gini coefficient, and the cards below show Mean income, Count. 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 Gini Coefficient Calculator using the default values shown in the calculator above:
Inputs
| Incomes (comma separated) | 20000, 35000, 48000, 60000, 85000, 150000 |
|---|
Results
| Gini coefficient | 0.34 |
|---|---|
| Mean income | $66,333.33 |
| Count | 6 |
With these inputs the calculator returns Gini coefficient: 0.34. Change any value in the calculator to see how the result moves.
What the results tell you
The results panel of the Gini Coefficient Calculator reports Gini coefficient, mean income and count. Compare these figures while changing one input at a time, and use the related calculators below to look at the same situation from another angle.
