🧮 Interpolation Calculator: Instantly Solve Missing Values with Precision
In today’s world of data science, engineering, and statistics, interpolation is an essential tool. When we are given two known values and need to estimate something in between, interpolation comes to the rescue. Our Interpolation Calculator is designed to make this process effortless — no more manual formulas or complex spreadsheets. Whether you’re a student or a professional, this tool helps you solve for unknown values between data points in seconds.
What is Interpolation?
Interpolation is a method of estimating unknown values that fall between known values. It’s widely used in mathematical analysis, physics, statistics, engineering, and more. For example, if you know the temperature at 10 AM and 12 PM, interpolation can help you estimate the temperature at 11 AM.
There are various types of interpolation, and the most commonly used is linear interpolation, which assumes a straight-line relationship between the known points.
Why Use an Interpolation Calculator?
Manually interpolating values using formulas can be time-consuming and error-prone. A good Interpolation Calculator eliminates the hassle by automating the process with 100% accuracy.
Here’s what makes our Interpolation Calculator powerful:

How the This Calculator Works
This Calculator uses the standard linear interpolation formula:
y=y1+(x−x1)(y2−y1)x2−x1y = y_1 + \frac{(x – x_1)(y_2 – y_1)}{x_2 – x_1}y=y1+x2−x1(x−x1)(y2−y1)
Where:
(x1,y1)(x_1, y_1)(x1,y1) and (x2,y2)(x_2, y_2)(x2,y2) are the two known points
xxx is the value at which you want to interpolate
yyy is the interpolated value
All you have to do is enter:
The first known point (x1,y1)(x_1, y_1)(x1,y1)
The second known point (x2,y2)(x_2, y_2)(x2,y2)
The desired xxx value to find yyy
Click Calculate, and the interpolated value appears instantly.

Types of Interpolation (Beyond Linear)
Although this Calculator focuses on linear interpolation, here are a few other types:
1. Polynomial Interpolation
Used when the data points don’t follow a straight line. It fits a curve that passes through all known points.
2. Cubic Interpolation
A specific case of polynomial interpolation that uses cubic polynomials. Often used in graphics and animation.
3. Spline Interpolation
Divides the interval between points into smaller sections and fits a polynomial in each, providing a smooth curve.
These advanced types are more complex but necessary in specific applications.
Example: Using the Interpolation Calculator
Problem:
You know the values:
At x1=4x_1 = 4x1=4, y1=10y_1 = 10y1=10
At x2=8x_2 = 8x2=8, y2=30y_2 = 30y2=30
What is the value of yyy when x=6x = 6x=6?
Solution using Interpolation Calculator:
y=10+(6−4)(30−10)8−4=10+2⋅204=10+10=20y = 10 + \frac{(6 – 4)(30 – 10)}{8 – 4} = 10 + \frac{2 \cdot 20}{4} = 10 + 10 = 20y=10+8−4(6−4)(30−10)=10+42⋅20=10+10=20
Result: y = 20
The Interpolation Calculator gives this result in just one click.

Frequently Asked Questions (FAQ)
Q1: What is an Interpolation Calculator?
An Interpolation Calculator is an online tool that estimates a value between two known data points using a formula, usually linear interpolation.
Q2: Is interpolation always accurate?
Interpolation is accurate within the range of the known data. Outside this range, it’s called extrapolation and is less reliable.
Q3: Can I use this tool for time or temperature?
Yes! As long as you know two reference values, you can interpolate any numeric data — including time, temperature, speed, and more.
Q4: Is the Interpolation Calculator free?
Absolutely. Our Interpolation Calculator is 100% free to use with no ads or pop-ups.
