Leveraging KPIs to Improve Your Marketing Strategies

Marketing KPIs act as guiding stars, helping you navigate the vast sea of data and identify what really matters. By understanding and leveraging KPIs, you can uncover valuable insights about your target audience, campaign reach, and engagement.


Armed with this information, you can fine-tune your strategies, tailor your messaging, and boost your marketing success.

Let's take a closer look:



ARR (Annual Recurring Revenue): Total recurring revenue from all customers over a year.

ARR = Monthly Recurring Revenue×12


ARR per FTE (Full Time Employee): ARR divided by the number of full-time employees.

ARR per FTE = ARR ÷ Number of FTEs ​


ARR (Annual Recurring Revenue) per FTE (Full-Time Equivalent) is a key metric in SaaS and other subscription-based businesses, indicating the revenue efficiency of the workforce.


Ideal ARR per FTE: This varies widely depending on the industry, company size, and business model. For high-performing SaaS companies, an ARR per FTE of $200,000 to $300,000 is often considered ideal. This range suggests efficient use of human resources in generating revenue.


Good ARR per FTE: A figure between $100,000 and $200,000 is typically seen as good, indicating a healthy balance between workforce size and revenue generation. It shows that the company is growing and using its human resources effectively, but there may still be room for optimization.


Bad ARR per FTE: Anything significantly below $100,000 might be considered suboptimal or bad, especially for established companies. This could indicate that the company is either overstaffed for the revenue it's generating or not utilizing its workforce effectively to drive revenue growth.


It's important to note that these figures can vary greatly. Early-stage startups often have lower ARR per FTE as they invest heavily in growth and development, while more mature companies might achieve higher efficiencies. Additionally, the nature of the product, target market, and sales strategies (like self-service vs. high-touch sales) can significantly impact this metric.


ARPU (average revenue per user): ARPU, which stands for Average Revenue Per User, is a key financial performance metric used primarily by subscription-based companies, including telecom and SaaS (Software as a Service) companies.

ARPU = Total Revenue in a Period ÷ Average Number of Users during that Period


Burn Rate: The rate at which a company is spending its capital.

Burn Rate = Cash Spent Over a Period Gross Burn Rate = Total Monthly Operating Costs

Net Burn Rate = (Monthly Revenue - Cost of Goods Sold) - Gross Burn Rate


CAC (Customer Acquisition Cost): Total sales and marketing expenses over a given period, divided by the number of customers acquired in that period.

CAC = Total Sales and Marketing Expenses ÷ Number of New Customers Acquired


CAC Payback Period: The time it takes for a customer to generate enough revenue to cover the cost of acquiring them.

CAC Payback Period = CAC ÷ Monthly Gross Margin per Customer


CPA (Cost Per Acquisition): Similar to CAC, CPA is the cost to acquire a paying customer. It can also be used in broader contexts, like the cost to acquire a user, regardless of whether they're a paying customer.

CPA = Total Cost of Campaign ÷ Number of Acquisitions


CTR (Click-Through Rate): The percentage of people who click on an ad or call-to-action button compared to the total number of impressions. It's a telling indicator of how effective your ads are in capturing attention and driving engagement.

CTR = (Number of Clicks ÷ Number of Impressions)×100%


For instance, if your ad receives 1,000 impressions and generates 100 clicks, your CTR would be 10%. This means that 10% of the people who saw your ad were intrigued enough to click on it.


Improving your CTR involves crafting compelling ad copy, using eye-catching visuals, and targeting the right audience. Additionally, conducting A/B testing can help you identify which elements of your ads are resonating with your audience and driving higher click-through rates.



Conversion Rate: The percentage of visitors who take a desired action.

Conversion Rate = (Number of Conversions ÷ Total Visitors)×100%


The conversion rate is like a high-five from a potential customer – it measures the percentage of people who take the desired action after encountering your marketing message. Whether it's making a purchase, signing up for a newsletter, or downloading an ebook, a higher conversion rate indicates that your message has struck a chord.

Here's the formula:

Conversion Rate = (Number of Conversions ÷ Number of Visitors) x 100


For example, let's say you have 1,000 visitors to your website and 100 of them make a purchase. Your conversion rate would be 10%. This means that for every 100 visitors, 10 of them are converting into customers.


But what if your conversion rate is low? Don't worry, there are several strategies you can implement to improve it. One approach is to optimize your landing pages to make them more compelling and persuasive. Another tactic is to enhance your call-to-action buttons to make them more prominent and enticing.



CPC (Cost Per Click): The cost of each click in a pay-per-click (PPC) marketing campaign.

CPC = Total Cost of Campaign ÷ Number of Clicks


CPL (Cost Per Lead): The cost of acquiring a lead.

CPL = Total Marketing Expenses ÷ Number of Leads Generated


CPM (Cost Per Thousand Impressions): The cost of a thousand ad impressions.

CPM = Total Ad Spend ÷ (Total Impressions ÷ 1000)


Lead to MQL (Marketing Qualified Lead) Conversion Rate: Percentage of leads that become MQLs.

Lead to MQL Rate = (Number of MQLs ÷ Total Number of Leads)×100%


LTV (Lifetime Value): The total revenue a business can expect from a single customer over the life of their relationship with the company.

LTV = Average Revenue per User (ARPU)×Average Customer Lifespan


LTV:CAC Ratio: (LTV:CAC) is a crucial marketing metric that measures the relationship between the lifetime value of a customer and the cost to acquire that customer.

LTV:CAC ratio = Lifetime Value (LTV) ÷ Customer Acquisition Cost (CAC)


It's important because it helps businesses evaluate the efficiency of their marketing investments and understand whether they are gaining enough value from their customers relative to the cost of acquiring them.


A good LTV:CAC ratio can vary based on industry and business size, but generally, a ratio of 3:1 is considered healthy. This means the lifetime value of a customer is three times the cost of acquiring them.

For smaller businesses or startups, achieving this ratio can be challenging due to higher initial customer acquisition costs and evolving business models. Larger, more established businesses often aim for a higher ratio, as they can leverage economies of scale and more efficient marketing strategies.


However, it's important to balance a high LTV:CAC ratio with the need for growth; too high a ratio could indicate under-investment in customer acquisition.


Customer Lifetime Value (CLTV):

Capturing new customers is great, but keeping existing ones is even better. CLTV measures the net profit generated by a customer over their entire relationship with your business. It takes into account repeat purchases, customer loyalty, and the average length of the customer relationship.

Here's the formula:

CLTV = Average Purchase Value x Purchase Frequency x Customer Lifespan


Let's break down the formula. The average purchase value refers to the average

amount a customer spends on each transaction. Purchase frequency represents how often a customer makes a purchase within a given time frame. And customer lifespan indicates the average length of time a customer remains engaged with your brand.


By calculating CLTV, you can gain insights into the long-term value of your customers. This information can help you make informed decisions about customer retention strategies, such as implementing loyalty programs or personalized marketing campaigns.



MQL to SQL (Sales Qualified Lead) Conversion Rate: Percentage of MQLs that become SQLs.

MQL to SQL Rate = (Number of SQLs ÷ Number of MQLs)×100%


MRR (Monthly Recurring Revenue): A key metric for SaaS and subscription based companies because it allows you to predict recurring revenue, and create forecasts and trends.

MRR = Average Revenue per Account x Total Accounts that Month


Net Revenue Retention: Measures the revenue retained from existing customers in a given period, including upsells, cross-sells, downgrades, and churn.

Net Revenue Retention = (Starting MRR + Expansion MRR - Churn MRR÷Starting MRR)


Pipeline Conversion Rates: The rate at which leads move through the sales pipeline stages.

Pipeline Conversion Rate = (Number of Opportunities that Advance to Next Stage ÷ Total Opportunities in Stage)×100%


SQL to Opportunity Conversion Rate: Percentage of SQLs that become opportunities.

SQL to Opportunity Rate = (Number of Opportunities ÷ Number of SQLs)×100%


Opportunity to Closed-Won Conversion Rate: Percentage of opportunities that result in a sale.

Opportunity to Closed-Won Rate = (Number of Closed-Won Deals ÷ Number of Opportunities)×100%


ROAS (Return on Ad Spend): The amount of revenue earned for every dollar spent on advertising.

ROAS = Revenue from Ad Campaign ÷ Cost of Ad Campaign


ROI (Return on Investment): A measure of the profitability of an investment.

ROI = (Net Profit ÷ Investment Cost)×100%


Rule of 40: A measure used in the SaaS industry that adds growth rate and profit margin. It's a simple and effective way to measure the companies ability to balance profitability and growth.


The goal for a healthy, mature company should be for its revenue growth rate and profit margin to exceed 40%. Sometimes, in the SaaS industry, businesses focus on growth at the expense of profitability and this metric keeps that in check.


For earlier stage startups whose business models are in flux, the Rule of 40 may not be as accurate and needs to be balanced with other KPIs.



Rule of 40 = Revenue Growth Rate + Profit Margin

Growth Rate = ARR in annual YoY Growth Profit Margin = EBITDA margin % = EDITDA ÷ Revenue



Run Rate / Runway: Estimates how long a company can operate before it runs out of cash.

Runway = Current Cash Balance ÷ Burn Rate


TAM (Total addressable market): Average revenue per user (ARPU) times the total number of potential customers in the target market.​

TAM = ARPU x Total potential customers


Time to Close: The average amount of time it takes to close a deal.

Time to Close = Average Number of Days from Opportunity to Close



These formulas provide a comprehensive view of various metrics crucial for understanding business performance, particularly in areas like marketing, sales, and financial management.


Optimizing Your Metrics for Maximum Efficiency

Metrics are the building blocks of meaningful analysis. They provide the data that drives decision-making and helps you uncover opportunities for improvement. However, it's important to optimize your metrics to ensure you are collecting the right data and measuring what matters most.


Imagine having a tool belt full of shiny gadgets, but not knowing which ones to use for the job at hand. By aligning your metrics with your marketing goals, you can focus on what matters and avoid drowning in a sea of irrelevant data.


Here are a few tips to optimize your metrics:

  • Define clear and specific goals for your marketing campaigns.

  • Identify the metrics that align with those goals.

  • Regularly review and refine your metrics to stay relevant.

  • Consistently track and analyze your data to identify patterns and trends.

When it comes to optimizing your metrics, it's crucial to start by defining clear and specific goals for your marketing campaigns. Without a clear direction, it's easy to get lost in the vast sea of data. By setting specific goals, you can narrow down your focus and determine which metrics are most relevant to your objectives.


Once you have established your goals, the next step is to identify the metrics that align with those goals. Not all metrics are created equal, and it's important to choose the ones that provide the most valuable insights. For example, if your goal is to increase website traffic, metrics such as page views, unique visitors, and referral sources may be more relevant than metrics like bounce rate or time on page.


However, optimizing your metrics is not a one-time task. It requires regular review and refinement to stay relevant. As your marketing strategies evolve and your goals change, so should your metrics. By regularly reviewing and refining your metrics, you can ensure that you are collecting the most accurate and up-to-date data.


Consistently tracking and analyzing your data is another key aspect of optimizing your metrics. Data alone is meaningless without analysis. By tracking your metrics over time and analyzing the patterns and trends that emerge, you can gain valuable insights into the effectiveness of your marketing efforts. This allows you to make data-driven decisions and identify areas for improvement.


By optimizing your metrics, you can swim through the data ocean with confidence, armed with the insights you need for success. So, take the time to define your goals, choose the right metrics, review and refine them regularly, and consistently track and analyze your data. With these steps in place, you'll be well on your way to maximizing the efficiency of your metrics and driving meaningful results for your business.

Applying the Right Metrics to Assess Your Marketing Campaigns

All marketing campaigns are not created equal, and neither should your metrics be. The metrics that matter most will vary depending on your campaign objectives, target audience, and industry. To effectively assess the success of your campaigns, it's crucial to apply the right metrics.


Let's explore some common marketing campaigns and the metrics that can help evaluate their performance:

1. Social Media Engagement:

When it comes to social media campaigns, metrics like likes, shares, comments, and click-throughs are your best friends. They indicate how well your content resonates with your audience and whether you're effectively driving engagement.


For example, measuring the number of likes on your posts can give you an idea of how well your content is being received by your audience. A high number of likes suggests that your content is engaging and valuable to your followers.


Similarly, tracking the number of shares can help you determine the reach of your campaign. If your content is being shared by your audience, it indicates that they find it interesting enough to share with their own networks, expanding your brand's visibility.


Comments on your posts provide valuable feedback and insights into how your audience perceives your content. Positive comments indicate that your campaign is resonating with your target audience, while negative comments can help you identify areas for improvement.


Click-throughs, on the other hand, measure how effective your call-to-action is in driving traffic to your website or landing page. By analyzing click-through rates, you can determine whether your social media campaign is successfully driving conversions.

2. Email Marketing:

Email marketing campaigns require metrics that focus on open rates, click-through rates, and conversion rates. These metrics help you measure the effectiveness of your subject lines, content, and calls-to-action.


Open rates indicate how many recipients opened your email, giving you an idea of how well your subject line captures attention. A high open rate suggests that your subject line is compelling and encourages recipients to engage with your email.

Click-through rates measure the number of recipients who clicked on a link within your email. This metric helps you assess the effectiveness of your content and calls-to-action, as a high click-through rate indicates that your email is successfully driving traffic to your desired destination.


Conversion rates are perhaps the most important metric for email marketing campaigns. They measure the percentage of recipients who completed a desired action, such as making a purchase or filling out a form. By tracking conversion rates, you can determine the overall success of your email campaign in driving meaningful actions.

3. Influencer Partnerships:

Metrics such as reach, engagement rate, and follower growth are essential when evaluating the success of influencer marketing campaigns. They help you gauge the impact of your collaborations and measure the return on your investment.


Reach refers to the number of people who have been exposed to your influencer's content. It helps you understand the potential audience size and the level of visibility your brand is receiving through the partnership.


Engagement rate measures the level of interaction and engagement generated by the influencer's content. It includes metrics like likes, comments, and shares. A high engagement rate indicates that the influencer's content is resonating with their audience and driving meaningful interactions.


Follower growth is another important metric to consider. It shows how many new followers your brand gained as a result of the influencer partnership. A significant increase in followers suggests that the collaboration has helped expand your brand's reach and attract new potential customers.

By tailoring your metrics to fit the specific nature of your campaigns, you can gain valuable insights and optimize your marketing efforts for maximum impact.
