Mobile marketing

K-factor is a metric used by app developers to indicate an app’s virality. K-factor measures how many additional users each existing user brings to the app. Adapted from medical terminology used to assess how fast a virus spreads, K-factor in the mobile app economy represents how many of your new users will invite others to try your app.

What is K-factor?

K-factor is an assessment of an app's viral potential or word-of-mouth potential. If one user tells a second and third user about your app, you’re obtaining a new user without any additional cost. In principle, K-factor is used to link organic installs to user acquisition (UA). However, many variables can impact traffic, such as campaign, countries, timing, etc., and lead to a lower or higher K-factor in your UA campaign.

Why is K-factor important?

K-factor is just one of many metrics that inform app marketers’ campaign spending. By understanding how paid traffic and installs impact organic installs, you can have a fuller picture of how your campaigns are performing. If you can prove your marketing is impacting organic installs as well as paid, you can better justify your campaign budgets and spend them more wisely.

How is K-factor calculated?

Below we’ve written the most widely used formula to calculate K-factor:

K = i * c

i= The number of app invites sent per customer

c= The average conversion rate of each invite

Let’s look at an example. Let’s say you have a fitness app in which you decide to reward loyal users who invite their family and friends to the app. So, you offer your loyal users 20% off their next monthly subscription when one of their friends downloads the app from the loyal user’s referral link.

Let’s say each of your users invites two friends. In this case, i = 2.

If one in four invitees convert to a new user, then, c = .25

Now, it’s time to multiply. K= 2 *.25 = ???

Question: What is the value of K-factor here?

The K-factor value would be 50%. (K = 2* .25 = .50)

If your fitness app started with a modest 200 active users with this K-factor, the next month should yield 300 active users.

What is a good K-factor?

A good K-factor is one that is higher than one, even fractionally. This indicates viral growth and that your K-factor surpasses your churn rate. A K-factor of one indicates stability as your app isn’t growing or declining. Conversely, a K-factor below one reveals that your app’s virality is in exponential decline.

In other words, your K-factor is good so long as it surpasses your app’s churn rate.

How to improve K-factor

It’s crucial to identify the influential aspects of your K-factor and optimize them as often as possible. Doing so will boost the number of installs from organic that come from the force of paid. ASO, optimization, and creating sharable apps are three key ways to lift your K-factor. Let’s cover how they each can serve to improve your app’s K-factor.

ASO

Effective App Store Optimization (ASO) is vital for app developers desiring more organic downloads. One of the largest ranking factors of ASO is download volume. Therefore, a large install base will help to boost rankings, regardless of whether users are paid or organic. When app stores see consistent traffic and an ever-increasing number of active users, rank increases. This creates a healthy circle of organic influencing paid, leading to a bigger K-factor.

Experiment, optimize, repeat

As you explore various channels, utilize different ad creatives, and try to find the source of the most valuable users, it’s imperative to be able to measure and analyze all your marketing campaigns. Only with accurate measurement and proper analytics can you know how to best optimize your campaigns to maximize your ROI. With a mobile analytics platform like Adjust, you can better understand your app’s K-factor as you effectively analyze and optimize all your campaigns in one place.

Sharable apps

The K-factor of an app benefits immensely if the app is made for sharing. Whether it be a multiplayer game, or a travel app that allows users to split the cost, encouraging your users to share the app with friends can turn one paid install into three or four more organic users. Of course, this is something to be determined at the beginning of an app’s development.

If your app isn’t built specifically for interaction with others, you can still consider incorporating a feature that makes your app more interactive. If we go back to our fitness app example, you could develop a chat/competition function where your users can challenge each other to a fitness challenge as well as invite potential users to join as well.

FAQs

What is K-factor | How to calculate K-factor | Adjust? ›

K factor is a ratio between the distance from the neutral bend line to the inside bend radius and the material thickness. K factor uses the formula K factor = δ/T.

How do you calculate the k-factor? ›

We define this neutral axis shift as t, as shown in Figure 2. We calculate k-factor by dividing t by the material thickness (Mt): k-factor = t/Mt, The k-factor is nothing more than a multiplier that can give you an accurate value for the relocated neutral axis.

How is K value calculated? ›

Equilibrium K value (K value): The ratio of the mole fraction in the vapor phase divided by the mole fraction in the liquid phase for a component in the equilibrium state.

What is the formula for k-factor referral? ›

Let's say each user invites one friend on average (i = 1), and every third invitee has successfully registered (c = ⅓). In this case, the K-factor = 1 * ⅓ = 33.3%. Assuming all goes well, this would mean that if our dating app initially had 100 active users, that number would soon grow to 133, and then 178, and so on.

What is K factoring? ›

K-factor is a metric used by app developers to indicate an app's virality. K-factor measures how many additional users each existing user brings to the app.

How do you calculate for K? ›

Formula for K for a Multi-step Reaction: K is the equilibrium constant for a reaction. If a reaction occurs in two or more steps, K for the overall reaction is calculated from the product of the individual K's for each step. In other words, K n where n = number of the last individual reaction.

How to calculate K-factor hvac? ›

K-Factor = True Flow/Measured Flow

The best way to determine the “true flow” is to perform an accurate duct traverse with a pitot tube or thermal anemometer in the duct upstream of the diffuser (make sure the duct only serves one diffuser).

How do you calculate the K factor in statistics? ›

The K-Factor formula is equal to I × C. In this instance, it is 5 × 0.125 = 0.625. Therefore, the app's K-Factor is 0.625, or 62.5%.

Yes, as long as you have the material's thickness and R-value, you can calculate the K value using the formula K = T / R.

What is K value factor? ›

The K-factor is defined mathematically as t/Mt, where t is the neutral axis location and Mt is the material thickness. Because of the specific properties of any given metal, there is no easy way to calculate that value perfectly, hence the chart in Figure 2. The K-factor is usually somewhere between 0.3 and 0.5.
