Performing polynomial regression in Excel involves fitting a polynomial equation to a set of data points. Unlike linear regression, which is straight-line fitting, polynomial regression fits a curve, making it suitable for more complex relationships between variables. Here’s how you can perform polynomial regression in Excel:
Calculating the Net Present Value (NPV) in Excel is a common financial analysis task. NPV measures the profitability of an investment by discounting all expected future cash flows to their present value.
Here’s how to calculate NPV in Excel:
Quadratic equations are a common mathematical problem, and you can efficiently solve them using Microsoft Excel. Here’s a systematic approach to finding the solutions to a quadratic equation in Excel:
Time Value of Money (TVM) analysis in Excel allows you to evaluate the worth of money over time, accounting for factors like interest rates and the timing of cash flows. It’s commonly used in finance to make decisions about investments, loans, and other financial transactions.
Here’s a guide on performing TVM analysis in Excel:

Interpolation is the process of estimating values within the range of available data. It is a fundamental tool in data analysis and visualization, and it can be performed effortlessly in Excel using various techniques.
Unlike extrapolation, which estimates values beyond the available data range, interpolation focuses on providing accurate estimates within the known data boundaries.
We will explore the methods and steps to interpolate in Excel effectively. We will start by discussing the different types of interpolation, and then we will provide step-by-step instructions on how to perform linear and polynomial interpolation. Finally, we will discuss the precision of interpolation and its use cases.
If you work with data, you might occasionally encounter SLK files. SLK, short for Symbolic Link, is a file format that can encapsulate data, formulas, and formatting in one file, making it particularly handy for data sharing across different spreadsheet applications or Excel versions.
There are two ways to open an SLK file in Excel:
