In this Excel tutorial, you will learn how to calculate the MACD indicator in Excel using exponential moving averages and create trading signals for technical analysis.
The Moving Average Convergence Divergence (MACD) indicator is a popular technical analysis tool used in stock trading and other financial markets to identify potential buy and sell signals. The MACD is calculated as the difference between two moving averages, the 26-day exponential moving average (EMA) and the 12-day EMA, and is often plotted along with a 9-day EMA of the MACD line, known as the signal line.
Here’s how to calculate the MACD indicator in Microsoft Excel:
In Excel, you can calculate the integral average, also known as a definite integral, by using the Sumproduct function.
Excel can approximate the definite integral of a dataset using the SUMPRODUCT function, implementing the trapezoidal rule. The trapezoidal rule approximates the area under a curve by dividing it into a series of trapezoids, where each trapezoid’s area is determined by the average height of its two vertical sides multiplied by its width.
Logarithmic average, also known as the geometric mean, can be calculated in Excel by using the geometric mean formula.

In this Excel tutorial, you will learn how to calculate covariance in Excel.
The XOR function in Excel is a logical function that allows you to compare two or more values and determine if an odd number of them are true. Learn how to use the XOR function in Excel with practical examples to validate data, check conditions, and improve your spreadsheet logic.

Earnings per share (EPS) is a financial metric that measures a company’s profitability. In this lesson, you will learn how to calculate EPS in Excel.

In this comprehensive lesson, you will learn how to calculate ROIC in Excel using the return on invested capital formula and understand how to measure business efficiency and profitability.

In this comprehensive lesson, you will learn how to calculate ROCE in Excel using the return on capital employed formula and understand how to measure business efficiency and profitability.
Return on Sales (ROS) is a financial ratio that measures a company’s efficiency in generating profits from its revenue. It is calculated by dividing the operating profit (or income) by the net sales. A higher ROS indicates greater profitability and better control over costs.
In this tutorial, I’ll show you how to calculate ROS in Excel with a simple ROS formula. All you need are two inputs: operating profit and net sales. Alternatively, you can use EBIT (earnings before interest and taxes) as a proxy for operating profit and revenue for net sales.
