Disadvantages

  • MAU alone does not reflect the quality or depth of user engagement, potentially masking inactive or low-value users.
  • Can be artificially inflated through marketing promotions or incentives without sustainable growth.
  • Does not account for user churn or retention, limiting insight into long-term customer loyalty.

Icon

Industry Benchmarks

Top digital banking platforms typically reach over 1 million MAU within 2 to 3 years of launch, signaling strong market adoption and scalability. Benchmarks vary by region and target market, but this threshold is a common indicator of competitive positioning. Monitoring MAU against these standards is vital for assessing growth and investor confidence.

Icon

How To Improve

  • Enhance user experience through intuitive design and personalized AI-driven financial solutions to boost engagement.
  • Implement targeted marketing campaigns based on user segmentation to attract and retain high-value customers.
  • Introduce rewards and loyalty programs that incentivize frequent platform use and deepen customer relationships.

Icon

How To Calculate

Calculate MAU by counting the number of unique users who have logged into or actively used the digital banking platform at least once during the month.

MAU = Count of unique users active in the platform during the month

Icon

Example of Calculation

If NovaBank Digital had 150,000 unique users log in or perform transactions in March, the MAU for that month is 150,000.

MAU = 150,000 unique users in March

  • Design deposit products with competitive rates that balance customer attraction and funding costs.
  • Leverage AI-driven pricing models to dynamically adjust interest rates in response to market changes.

Icon

How To Calculate

Net Interest Margin is calculated by subtracting interest expenses on deposits from interest income on loans, then dividing by average earning assets, and expressing the result as a percentage.

NIM = ((Interest Income from Loans – Interest Expense on Deposits) / Average Earning Assets) × 100%

Icon

Example of Calculation

Suppose NovaBank Digital earned $5 million in interest from loans and paid $1.5 million in interest on deposits. The average earning assets during the period were $150 million. The NIM calculation would be:

NIM = (($5,000,000 – $1,500,000) / $150,000,000) × 100% = (3,500,000 / 150,000,000) × 100% = 2.33%

This indicates NovaBank’s net interest margin is slightly below the digital banking average, suggesting room for improvement in lending or deposit strategies.


Icon

Tips and Trics

  • Regularly segment loan and deposit portfolios to identify high-margin opportunities.

Icon

How To Improve

  • Implement automation and AI-driven workflows to reduce manual processing costs.
  • Adopt cloud infrastructure to lower IT and maintenance expenses.
  • Optimize staffing levels by focusing on lean operations and cross-functional teams.

Icon

How To Calculate

The cost-to-income ratio is calculated by dividing operating expenses by operating income, then multiplying by 100 to express it as a percentage.

Cost-to-Income Ratio = (Operating Expenses / Operating Income) × 100%

Icon

Example of Calculation

Suppose NovaBank Digital reports operating expenses of $4 million and operating income of $10 million for the quarter. The cost-to-income ratio would be:

(4,000,000 / 10,000,000) × 100% = 40%

This 40% ratio indicates NovaBank Digital is operating efficiently, well below the traditional bank average, highlighting strong digital banking operational efficiency.

  • Streamline onboarding processes to reduce drop-offs and speed up customer activation.
  • Leverage data analytics to identify and invest in the most cost-effective acquisition channels.

Icon

How To Calculate

Calculate CAC by dividing the total marketing and sales expenses within a period by the number of new customers acquired during that same period.

CAC = (Total Marketing + Sales Expenses) / Number of New Customers Acquired


Icon

Example of Calculation

If NovaBank Digital spends $50,000 on marketing and sales in a month and acquires 1,000 new customers, the CAC is calculated as follows:

CAC = $50,000 / 1,000 = $50 per customer

This means NovaBank spends $50 to acquire each new user, which falls within the acceptable industry range for digital banks.


Icon

Tips and Trics

  • Always compare CAC with Customer Lifetime Value (LTV) to ensure acquisition costs are justified.
  • Track CAC by channel to identify which marketing efforts deliver the best ROI.
  • Monitor CAC trends monthly to quickly detect inefficiencies or seasonal impacts.
  • Integrate CAC analysis with churn rate data to understand the true cost of acquiring long-term customers.
