How to Use the Linear Interpolation Calculator - An Easy Step-by-Step Guide
Prepare Your Data Points
Before using the calculator, ensure you have two known data points. These points should be represented as coordinates (x1, y1) and (x2, y2). The x-values must be different from each other to avoid division by zero errors. For example, if you're analyzing temperature data, you might have (10°C, 50°F) and (30°C, 86°F).
Input Known Points
Enter your first data point in the x1 and y1 fields, then enter your second data point in the x2 and y2 fields. The calculator accepts both positive and negative numbers, as well as decimal values. Ensure accuracy when entering these values as they directly affect the interpolation result.
Specify Target Value
In the target x field, enter the x-value for which you want to find the corresponding y-value. This value should ideally fall between x1 and x2 for true interpolation, though the calculator can also perform extrapolation for values outside this range.
Calculate and Review
Click the "Calculate Interpolation" button to process your data. The calculator will instantly compute the result using the linear interpolation formula and display both the final answer and detailed step-by-step calculations showing how the result was obtained.
How does Linear Interpolation Calculator Works
Linear Interpolation Formula
Understanding the Formula Components
y1 (Starting Point)
The y-coordinate of the first known point, serving as the baseline for the calculation.
(x - x1) (Horizontal Distance)
The distance along the x-axis from the first known point to the target point.
(y2 - y1) / (x2 - x1) (Slope)
The rate of change between the two known points, representing the line's steepness.

Frequently Asked Questions
Linear interpolation is a mathematical method used to estimate unknown values that fall between two known data points. It assumes a straight-line relationship between the points and is ideal for situations where you need to find intermediate values in datasets, predict trends, or fill gaps in data series.
Linear interpolation provides exact results when the actual relationship between data points is truly linear. For non-linear relationships, it gives approximations that are most accurate when the data points are close together and the curve between them is relatively straight.
Yes, our calculator can perform extrapolation when your target x-value falls outside the range of your known points. However, extrapolation results should be used with caution as they assume the linear trend continues beyond the known data range.
If x1 equals x2, the interpolation formula becomes undefined due to division by zero. The calculator will detect this error and prompt you to enter different x-values to ensure valid calculations.
