The k-factor is a term used in marketing that refers to the rate of customer acquisition.

It is important for businesses to understand and calculate the k-factor so they can determine how much money they need to spend on marketing in order to acquire new customers.

The term “k-factor” is simply picked from the medical field where it refers to a numerical measure that is used in epidemiology. In epidemiology, this basic reproduction number indicates whether or not a virus is growing or declining. A k-factor of 1 implies a “steady” condition where the virus is neither increasing nor decreasing; while a k-factor of higher than or lower than 1 indicates spreading or remission respectively.

In this blog post, we discuss what the k-factor is in marketing and how it impacts marketing efforts.

We also provide tips for calculating the k-factor for your business and how to interpret it.

Measuring Success

The k-factor is an important metric for businesses to track because it can help them determine how successful their marketing efforts are.

The k-factor takes into account both the cost of acquiring a customer and the lifetime value of that customer.

By calculating the k-factor, businesses can see whether they are making a profit on each new customer they attract through marketing. If not, they might want to re-evaluate their strategies in order to increase profitability or reduce costs.

How to Calculate the K-Factor

K-factors are typically calculated by dividing the total number of customers acquired over some period (such as one year) by the total cost of acquiring those customers during that same time frame.


There are a few different ways to calculate the k-factor, but all of them involve dividing two key metrics: customer acquisition cost (CAC) and lifetime value (LTV).

CAC is simply the total amount of money spent on marketing in order to attract new customers.

On the other hand, LTV is the average amount of revenue a customer generates over their lifetime with your company (usually defined as three years).

In order to calculate k-factor, you need to know the customer acquisition cost and lifetime value for each marketing channel.

For example: if it costs £100 per lead generated via email, but only £25 per lead from Facebook ads; then k-factors would be much higher for email marketing than Facebook. If the k-factor is high, it means that the channel has a good return on investment (ROI).

Measuring Effectiveness

The k-factor can also be used as a metric for measuring the effectiveness of different types of marketing campaigns and channels

The k-factor is an important metric to understand the effectiveness of your marketing campaigns because it helps you see which channels are working best and where there might be room for improvement.

For instance, if k-factors are low across all channels, then this indicates that customers aren’t engaging with your brand in any meaningful way and so they won’t continue spending money on it.

On the opposite end, if the k-factor is high for one channel but not others then perhaps there’s something specific about that channel which makes people more likely to engage with your brand; thus spending more money over time as a result of being engaged.

The k-factor can also be used to evaluate how much you should spend on advertising vs organic content in order to reach customers at scale without breaking the bank!

For example: if k-factors are higher for email marketing than Facebook, then maybe it would make sense to allocate more resources (time and money) towards email marketing instead of Facebook.

Concluding Remarks

The k-factor can help businesses determine if their current marketing strategy is working or not by comparing k-factors across channels, as well as seeing how many customers they’re gaining over time with each channel.

The K factor in marketing helps businesses understand how much money they need to spend on marketing in order to acquire new customers.
