Use this interpolation calculator to accurately estimate unknown values within the range of a set of data points.

## How to Use the Interpolation Calculator

To use this calculator, enter the known points (x0, y0) and (x1, y1) along with the value of x for which you want to find the interpolated y value. Click on “Calculate” to get the result. Make sure that all fields are filled with numerical values before calculating.

## How It Works

The calculator uses linear interpolation to estimate the value of a function for any value between two known values. Linear interpolation assumes that the change between two values is linear and calculates the missing data point accordingly.

## Calculation Formula

The formula used for linear interpolation is:

*y = y0 + [(x – x0) * (y1 – y0)] / (x1 – x0)*

## Limitations

This calculator assumes that the two known points are distinct and that x1 is not equal to x0; otherwise, division by zero would occur. Additionally, linear interpolation provides an approximation that may not be accurate if the actual data points do not follow a linear pattern.
