Formula for Calculating ROI on a New Software Investment

- by Nathan Robinson

The decision to invest in new software often involves significant capital and operational changes, making the assessment of its financial return, or **Return on Investment (ROI)**, a critical step. A clear and accurate ROI calculation helps justify the expense, prioritize projects, and measure the long-term success of the implementation.

The Standard ROI Formula

The fundamental formula for calculating ROI is a ratio that compares the net gain from an investment to its total cost. For software investments, this is adapted to consider the specific benefits and costs associated with the technology.

The universal ROI formula is:

$$ROI = \frac{\text{Net Benefit of Investment}}{\text{Cost of Investment}} \times 100\%$$

In the context of a new software implementation, the formula can be expressed as:

$$\mathbf{ROI} = \frac{(\text{Total Financial Benefits} – \text{Total Software Costs})}{\text{Total Software Costs}} \times 100\%$$

The result is expressed as a **percentage**, indicating the return for every dollar invested. For example, an …

Professional Email Setup Tips for Businesses

- by Nathan Robinson

Email remains most companies’ top channel for sales, support and general communications. However, without purposeful setup decisions, scattered email habits can undermine perceptions of your professionalism and reliability.

From addresses to greetings and signatures, many elements comprise a thoughtful email foundation that elevates trust. Follow this comprehensive guide to implement structural email best practices for your business across key areas.

Secure an Email Domain for Your Business

An email address utilising your company domain name signals business legitimacy from the first touchpoint. For example, contact@yourcompany.com intrinsically reads as more professional than yourname@genericmail.com.

If you currently lack a registered business domain name, prioritise purchasing your company identity or brand as a top-level domain (e.g. .com). Then, subscribe to reliable email hosting services that allow you to create corporate email accounts using your domain.

Take time upfront to establish the proper branded email real estate, even if starting small. This sets the …

What are the assumptions of ordinary least squares (OLS) in econometrics

- by Nathan Robinson

Ordinary Least Squares (OLS) is the simplest and most widely used estimation technique in econometrics. It provides the Best Linear Unbiased Estimators (BLUE) for the parameters in a linear regression model, provided a specific set of assumptions, known as the Classical Linear Model (CLM) assumptions, are met.

When these assumptions hold, the OLS estimates are considered reliable and trustworthy for statistical inference. When they are violated, the results can be misleading, biased, or inefficient.

Here are the nine core assumptions of OLS, grouped by their impact on your model.

Group 1: Assumptions for Linearity and Data Quality

These assumptions ensure the model is correctly specified and the data is appropriate.

1. Linearity in Parameters

The relationship between the dependent variable and the independent variables must be linear in the parameters.

  • Formal Statement:
  • Implication: This does not mean the variables themselves must be linear; you can use transformations like
