They trust you with their money because you give them value in exchange. What does customer retention mean? And how can you achieve customer retention through relationship-building strategies?

The customer retention definition in marketing is the process of engaging existing customers to continue buying products or services from your business. The best customer retention tactics enable you to form lasting relationships with consumers who will become loyal to your brand. They might even spread the word within their own circles of influence, which can turn them into brand ambassadors. Additionally, at best, your probability of selling to an existing customer is at least 40 percent more likely than converting someone who has never bought from you before.

Existing customers also spend 31 percent more than new leads, and when you release a new product, your loyal customers are 50 percent more likely to give it a shot. Those statistics should prove sufficient to compel you to build and test out a customer retention strategy.

Companies can calculate their customer retention rates in different ways. During that same period, of them return to buy something else from you. Those are the two numbers that will allow you to calculate your customer retention rate. However, you have to discount any new customers you bring on during those two months.

You should only count the people who bought something from you prior to the two-month start date among your existing customers.

Start by subtracting the number of customers acquired turning the calculation period from your total customer base at the end of the period. Divide that number by the number of customers you had at the start of the period and divide by You have 50, customers at the start of a calculation period of two months. During those two months, you acquire 1, customers, and at the end of the period, you have 40, customers.

If we multiply that number bywe get a customer retention rate of 81 percent. Now that you know how important customer retention is, how do you achieve better rates? Before you tackle any marketing strategyyou need a goal. First, calculate your existing customer retention rate. You have to start somewhere. You need a goal you can feasibly hit.

How to Perform Customer Survival Analysis

Consider the size of your customer base as well as the type of product you sell. Some products are tailor-made for customer retention. For instance, people always need to refill their household supplies, such as dish soap and toilet paper.

You can create a more ambitious goal in that case. Once you know that, you can figure out how they make their decisions. Then analyze what convinces your customers to buy. Once you understand the customer journey, you can optimize each stage and improve customer retention in the process.

First impressions matter, right? Make sure the checkout and delivery process is as smooth as possible. Send a thank-you email to let the customer know how much you appreciate their business, and direct them to any helpful videos or guides. Perceived value is almost as important as actual value. Your customers have to see your business as the ultimate solution to a problem.

For instance, corporate social responsibility has become a primary focus for many companies.By being aware of and monitoring churn rate, companies are equipped to determine their customer retention success rates and identify strategies for improvement. We will use a machine learning model to understand the precise customer behaviors and attributes which signal the risk and timing of customer churn.

Understanding our dataset:. We will use the Telco Customer Churn dataset from Kaggle. The raw dataset contains entries. All entries have several features and a column stating if the customer has churned or not.

To better understand the data we will first load it into pandas and explore it with the help of some very basic commands. We can see that our data is divided into three types. Exploratory Data Analysis. The goal of this section is to get comfortable with our data. We will do bivariate analysis. It is the simplest form of analyzing data where we examine how each variable relates to the churn rate. For categorical features, we can use frequency table or bar plots which will calculate the number of each category in a particular variable.

For numerical features, probability density plots can be used to look at the distribution of the variable. All visualizations for categorical variables will be done in tableau public. The following inferences can be made from the above bar plots. The churn percent is almost equal in case of Male and Females.

The percent of churn is higher in case of senior citizens. The churn rate is higher in case of customers who have phone services. Customers with an electronic payment method have a higher churn rate compared to other payment methods.

Customers with no internet service has a lower churn rate.

Churn rate is much higher in case of Fiber Optic InternetServices. Customers who do not have services like OnlineSecurity, OnlineBackup, and TechSupport have left the platform in the past month.

Now let's look at the numerical variables. This section is a fundamental part of machine learning. If this section is not done properly, our model will not work. In this section we will clean up our dataset by dropping irrelevant data, treating missing values, and converting our variables to the proper data type.

In our dataset, we can see that customer ID is not needed for our model so we drop the variable.Customer churn, also known as customer attrition, occurs when customers stop doing business with a company.

The companies are interested in identifying segments of these customers because the price for acquiring a new customer is usually higher than retaining the old one. For example, if Netflix knew a segment of customers who were at risk of churning they could proactively engage them with special offers instead of simply losing them. In this post, we will create a simple customer churn prediction model using Telco Customer Churn dataset. We chose a decision tree to model churned customers, pandas for data crunching and matplotlib for visualizations.

We will do all of that above in Python. The code can be used with another dataset with a few minor adjustments to train the baseline model. We also provide a few references and give ideas for new features and improvements. You can run this code by downloading this Jupyter notebook. We use pandas to read the dataset and preprocess it. Telco dataset has one customer per line with many columns features. We remove those samples and set the type to numeric float.

We have 2 types of features in the dataset: categorical two or more values and without any order and numerical. Most of the feature names are self-explanatory, except for:. There are customers in the dataset and 19 features without customerID non-informative and Churn column target variable.

Most of the categorical features have 4 or less unique values. We combine features into two lists so that we can analyze them jointly.

Numeric summarizing techniques mean, standard deviation, etc. That is the reason we use histograms. No data point is disconnected from distribution or too far from the mean value. To confirm that we would need to calculate interquartile range IQR and show that values of each numerical feature are within the 1. We could convert numerical features to ordinal intervals. One reason to convert it would be to reduce the noise, often small fluctuates are just noise.

We look at distributions of numerical features in relation to the target variable. We can observe that the greater TotalCharges and tenure are the less is the probability of churn. To analyze categorical features, we use bar charts. We observe that Senior citizens and customers without phone service are less represented in the data.

The next step is to look at categorical features in relation to the target variable. We do this only for contract feature. Users who have a month-to-month contract are more likely to churn than users with long term contracts.

Target variable distribution shows that we are dealing with an imbalanced problem as there are many more non-churned as churned users.So why is calculating your customer retention rate so important? Quantifying your success helps you put initiatives in place to keep your company strong, but there are a few facts to keep in mind:.

This is because selling to customers who you already have a relationship with is more effective. Upselling to existing customers is usually more lucrative than whatever sale you would make on a new client. As you can see, customer retention is one of the best ways to grow the revenue of your business.

The moral of the story: You want loyal customers. How, then, do you improve your customer retention rate? Below are a few metrics and how they are used to calculate CRR. This formula should work for any business regardless of size. It helps to break the calculation into parts. You are looking for the number of customers that remain at the end of a given period without counting the number of new customers that were acquired during that period.

During that period, you lost 8 customers, but you gained 21 N new customers. This means that at the end of the period, you had of your original customers, plus 13 new customers, so you now have customers E at the end of the period. Input those numbers into the formula:.

You should aim for at least 85 percent for your business to remain scalable and strong. There are countless ways to help improve your retention rate, but if you really want to be successful, you have to be willing to truly evaluate your company, identify why some customers are leaving, and then put an actual customer retention plan in place.

This makes improving your CRR specific to your business. Here are some popular tips—applicable to all companies—to consider. These will set you on the right path. You want to under-promise and over-deliver. Be as realistic as possible and then do your best to outperform what the customer is expecting.

This helps create brand loyalty, and when customers feel they can trust you, it keeps them coming back. This also pushes your company to work with clear goals in mind and makes it easier to impress your customers.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Customer attrition, also known as customer churn, customer turnover, or customer defection, is the loss of clients or customers. Telephone service companies, Internet service providers, pay TV companies, insurance firms, and alarm monitoring services, often use customer attrition analysis and customer attrition rates as one of their key business metrics because the cost of retaining an existing customer is far less than acquiring a new one.

Companies from these sectors often have customer service branches which attempt to win back defecting clients, because recovered long-term customers can be worth much more to a company than newly recruited clients. Companies usually make a distinction between voluntary churn and involuntary churn.

Voluntary churn occurs due to a decision by the customer to switch to another company or service provider, involuntary churn occurs due to circumstances such as a customer's relocation to a long-term care facility, death, or the relocation to a distant location. In most applications, involuntary reasons for churn are excluded from the analytical models. Analysts tend to concentrate on voluntary churn, because it typically occurs due to factors of the company-customer relationship which companies control, such as how billing interactions are handled or how after-sales help is provided.

Since these models generate a small prioritized list of potential defectors, they are effective at focusing customer retention marketing programs on the subset of the customer base who are most vulnerable to churn.

As we were discussing applications of machine learning into SaaS businesses, the conversation quickly shifted to customer churn management.

All businesses in the consumer market and enterprise sectors have to deal with churn as it could end up affecting the company revenue numbers and thereby influence policy decisions. Additionally as per the White House Office of Consumer Affairs, it is 6—7 times more expensive to acquire a new customer than to retain an old one.

The CEO of this particular company has been using traditional retroactive churn management based on simple statistics model. His team has been listing high-propensity churners and addressing their needs through special concierge services. The business team realized that this special treatment for churning customers is not a sustainable process and they need a holistic churn management strategy thats takes into account risk and associated risk tolerancethe level and cost of the retention intervention for different customer segments that is more systemic and continuous.

Customer Churn refers to the rate of customer attrition in a company or in simpler words speed at which customer leaves your company or service.

Here are 6 time-tested steps to make sure you are focusing on retaining your customers — we are going to focus only on step 2 and parts of step 3 for this article. While at this, remember that this is not about blaming the product or customer success group for the churn but to create a strategy to improve customer retention. We also believe that the approach of risk analysis-decision making-marketing segmentation is a generic enough structure that can be used for many business problems and not just churn analysis.

A predictive Churn Model is a straightforward classification tool: look at the user activity from the past and check to see who is active after a certain time and then create a model that probabilistically identifies the steps and stages when a customer or segment is leaving your service or product.

Having a predictive churn model gives you awareness and quantifiable metrics to fight against in your retention efforts. This gives you the ability to pattern habits of customers who leave, and step in before they make that decision. Without this tool, you would be acting on broad assumptions, not a data-driven model that reflects how your customers really act. Lets see what kind of data do we need to to asses the triggers that caused them to ultimately leave your company.
