For many organisations, growth has traditionally meant increasing sales, entering new markets, or launching new products.
Yet the most successful organisations understand a fundamental truth:
Profitability is not created by growth alone. It is created by the relationship between cost optimisation, operational efficiency, and return on investment (ROI).This distinction matters more than ever.
According to Deloitte’s CFO Insights, more than one-third of CFOs identified cost management as a top strategic priority, but the focus is increasingly shifting from traditional cost-cutting to cost optimisation; freeing up capital that can be reinvested into long-term growth initiatives rather than simply reducing expenses.
For CEOs and CFOs, the challenge is no longer how to spend less.
The challenge is how to create more value from every naira, cedi, or shilling invested in the business.
Why Cost Optimisation Is Different from Cost Cutting
Many organisations still approach profitability through periodic cost-cutting exercises.
Budgets are reduced.
Hiring is frozen.
Projects are paused.
The problem is that these measures often weaken long-term competitiveness.
Deloitte’s research on cost optimisation argues that organisations should focus on strategically reallocating resources toward areas that create sustainable value rather than pursuing blanket reductions in expenditure. According to Deloitte, modern cost optimisation aims to release capital for innovation, capability building, and market expansion while maintaining operational resilience.
In other words:
- Cost Cutting = Spending Less
- Cost Optimisation = Generating More Value from Existing Resources
- The distinction may appear subtle, but it has significant implications for profitability and growth.
The Three Metrics Every CEO and CFO Must Track
While organisations monitor dozens of KPIs, three metrics consistently determine whether growth translates into profitability:
1. Return on Investment (ROI)
ROI measures how effectively capital generates value.
Formula:
ROI (%) = ((Net Profit from Investment – Cost of Investment) ÷ Cost of Investment) × 100
Example:
If you invest $100,000 in a digital transformation initiative and generate $150,000 in additional profit:
ROI = (($150,000 – $100,000) ÷ $100,000) × 100
ROI = 50%
Every technology purchase, expansion initiative, hiring program, procurement investment, and transformation project should be evaluated using ROI analysis.
According to McKinsey, leading organisations increasingly evaluate operational and technology initiatives based on measurable value creation rather than implementation success alone.
2. Operating Margin
Operating Margin shows how efficiently revenue is converted into operating profit.
Formula:
Operating Margin (%) = (Operating Income ÷ Revenue) × 100
Example:
Revenue = $10 million
Operating Income = $2 million
Operating Margin = 20%
A rising operating margin often indicates successful cost optimisation and stronger operational discipline.
3. Revenue per Employee
One of the most powerful productivity indicators available to executives is revenue generated per employee.
Formula:
Revenue per Employee = Total Revenue ÷ Total Number of Employees
Example:
Revenue = $50 million
Employees = 500
Revenue per Employee = $100,000
This metric helps leaders determine whether workforce growth is translating into business value.
The Operational Efficiency Formula
Many organisations focus on revenue growth while overlooking operational efficiency.
However, McKinsey’s operational excellence research suggests that productivity improvements remain one of the strongest drivers of long-term performance. The firm’s 2024 productivity survey highlights operational excellence as a critical lever for unlocking sustainable productivity gains across organisations.
A practical operational efficiency formula is:
Operational Efficiency Ratio = Operating Expenses ÷ Revenue
Example:
Operating Expenses = $7 million
Revenue = $10 million
Operational Efficiency Ratio = 70%
The lower the ratio, the more efficiently the business converts revenue into profit.
Many high-performing organisations continuously seek to reduce this ratio through automation, workflow redesign, procurement optimization, and improved resource allocation.
The Business Process Optimisation Formula
One of the most overlooked drivers of profitability is business process optimization.
What is business process optimization?
Business process optimization is the systematic improvement of workflows to reduce waste, improve speed, eliminate duplication, and increase output.
A simple business process optimization example is procurement automation.
Consider an organisation where procurement approvals require multiple emails, spreadsheets, and manual reviews. Each request takes five days to process.
After digitisation:
- Approval time drops to one day
- Administrative effort reduces significantly
- Procurement visibility improves
- Supplier management becomes more efficient
The impact can be measured using:
Process Efficiency Improvement (%) = ((New Process Time – Old Process Time) ÷ Old Process Time) × 100
If procurement processing time reduces from five days to one day:
Efficiency Improvement = ((1 – 5) ÷ 5) × 100
Efficiency Improvement = -80%
This represents an 80% reduction in processing time.
According to McKinsey’s research on next-generation operational excellence, organisations that combine process improvement with technology and analytics create faster, smarter, and more resilient operations.
The Profitability Formula Most Leaders Ignore
The most important profitability formula is not revenue growth.
It is:
Profitability = Revenue Growth + Productivity Growth – Cost Growth
Many businesses focus exclusively on increasing revenue while allowing costs and complexity to rise at the same pace.
The result?
Revenue grows.
Margins stagnate.
Research from PwC highlights that organisations leveraging data, analytics, and operational improvements outperform peers by approximately 5% in productivity and 6% in profitability.
This demonstrates why productivity improvement strategies often create greater shareholder value than revenue growth alone.
The CEO and CFO Playbook
If you want sustainable profitability, focus on five priorities:
- Evaluate every major investment using ROI analysis.
- Measure operating margins consistently.
- Monitor revenue per employee.
- Invest in business process optimization initiatives.
- Build an organisation-wide operational efficiency strategy.
The most successful companies are not necessarily those that spend the least.
They are the ones that consistently convert resources into value more effectively than competitors.
As McKinsey notes in its operational excellence research, productivity is not simply an operational metric; it is a strategic capability that directly influences financial performance and long-term competitiveness.
For today’s CEOs and CFOs, the formula for sustainable growth is increasingly clear:
Cost Optimisation + Operational Efficiency + Disciplined ROI = Sustainable Profitability.
And in a world where capital is expensive and competition is increasing, that formula may be your strongest competitive advantage.
