Introduction

Cloud computing delivers IT resources, such as servers, computing power, networking, and databases, over the internet on an "on-demand" basis. Leading cloud infrastructure providers include Amazon Web Services (AWS), Microsoft Azure and Google Cloud. For this guide, we'll use AWS …

In this blog post, we explore the topic of multiple life functions within actuarial science. Up until now, our focus has been on insurance products that revolved around the life of an individual. However, in this exploration, we direct our focus to insurance products that involve multiple insured persons. We'll begin by exploring the various types of such products and then roll up our sleeves to construct a basic model using Python, leveraging the cashflower package.

Expanding upon the concept of life insurance …

In the world of actuarial science, we frequently encounter optimization problems. These challenges are most prevalent in the realm of pricing, where our goal is often to achieve a specific objective, such as expected profit. In this post, we will dive into a simple actuarial optimization problem and demonstrate how to solve it using two tools: Excel's Solver and Python.

Scenario

Let's consider a 3-year term policy with a net premium of €100. We aim to find a profit margin that yields a present value of premiums equal to €3000, assuming …

In this post, we will shed light on what net premium reserves are, how to calculate them and even build a simple actuarial cash flow model to determine their value.

The concept behind net premium reserves

In a previous blog post, we discussed the concept of net premiums. We mentioned the use of the equivalent principle to derive the value of net premiums paid periodically. What was the equivalent principle all about?

To put it simply, when an insurance contract …

In this blog post, we're going to talk about net premiums in insurance. We'll explain what they are, how to calculate them, and even walk you through some practical exercises using Python with real-life examples.

While we touched upon the concept of net single premiums in a previous discussion about life insurance, real-life scenarios often involve monthly premium payments for life insurance policies.
