How to use this tool?
This calculator performs exponential regression to fit data to the model y = a * b^x.
- Enter data points in the text area. Each point on a new line with x and y separated by a comma or space (e.g.,
1,2then2,4). - All y-values must be positive (greater than 0) because the method uses natural logarithms.
- Provide at least 3 data points for a reliable result.
- Click Calculate to see the regression equation y = a * b^x and the step-by-step solution.
Output: The result shows the coefficient a and base b rounded to 6 decimal places, along with the intermediate log values.

Frequently Asked Questions
Exponential regression is a method to fit data to an exponential curve of the form y = a * b^x, where a and b are constants.
At least 3 data points are required to perform exponential regression.
Exponential regression requires all y values to be positive because the natural logarithm is used. Negative or zero y values are not allowed.
