A sourcing option can be cheaper at low utilisation and more expensive at high utilisation. The difficult part is not calculating the crossover point. It is deciding whether the organisation will actually operate on the side of the threshold it expects.
The 2015 examination includes a simple equipment question comparing renting with leasing.
The source provides:
- rental cost of $100 per day;
- leasing maintenance of $3,000 annually;
- leasing operating cost of $70 per day.
The breakeven equation is straightforward:
Renting cost = Leasing cost
100d = 3,000 + 70d
30d = 3,000
d = 100 days
So, using only the examination assumptions, the two options are equal at 100 days of use.
The more valuable leadership question is what comes after the arithmetic.
The Strategic Context
Procurement choices frequently contain fixed and variable cost.
Owning or leasing may create:
- fixed commitment;
- maintenance;
- financing;
- storage;
- insurance.
Renting may reduce fixed commitment but create a higher cost per use.
At low utilisation, flexibility can be more valuable.
At high utilisation, the fixed-cost option may become economically superior.
This logic appears across:
- construction equipment;
- vehicle fleets;
- manufacturing assets;
- software licences;
- temporary facilities;
- specialist test equipment;
- warehouse space.
Breakeven is therefore a capital-allocation tool.
What Leaders Commonly Misread
The first mistake is treating the breakeven point as the decision.
It is only one input.
The second is assuming forecast utilisation will occur.
If the organisation expects 130 days of use but actual utilisation is 60, the “cheaper” lease may become more expensive.
The third is ignoring obsolescence.
A long-term commitment to rapidly changing equipment creates risk not captured by daily cost.
The fourth is ignoring availability.
Rental may be cheaper but useless if equipment cannot be obtained when critical.
The fifth is ignoring strategic reversibility.
A flexible option can preserve the ability to change direction.
Reframing the Issue
Use the ERANORTH Breakeven Sourcing Model:
Fixed cost + variable cost + expected use + uncertainty + reversibility
The arithmetic identifies the crossover.
The strategic analysis asks whether the organisation should commit.
Fixed cost
What must be paid regardless of utilisation?
Variable cost
What changes with usage?
Expected use
What is the realistic operating demand?
Uncertainty
How wide is the utilisation range?
Reversibility
How easy is it to exit or change the arrangement?
This is a stronger sourcing decision than comparing day rates.
Strategic Analysis: Expected Usage Is a Distribution, Not One Number
Suppose a project forecasts 120 days of equipment use.
At first glance, the exam model suggests leasing.
But leadership should test scenarios.
If delay compresses the work, use may fall to 80 days.
If scope expands, it may rise to 160.
If the equipment is required intermittently, storage and mobilisation may matter.
If rental supply is scarce, availability may outweigh price.
The decision should therefore examine the probability around the threshold.
A sourcing choice is more robust when it remains acceptable across several plausible scenarios.
Capital and Opportunity Cost
The source question compares rental and leasing cost only.
A real enterprise decision may also involve capital constraints.
Money committed to one asset cannot be invested elsewhere.
That matters especially where the equipment is not strategically distinctive.
A business may rationally pay a higher nominal rental rate because it values flexibility and prefers to allocate capital to core production assets.
Conversely, repeated rental of a highly utilised critical asset may signal that the organisation is paying a premium for flexibility it no longer needs.
Strategic Analysis: Breakeven Can Reveal Capability Strategy
Repeated sourcing decisions can reveal a deeper organisational question.
If a company continually rents the same specialist equipment above the economic crossover point, perhaps the requirement is no longer temporary.
It may have become a recurring capability need.
Conversely, owning an underutilised asset simply because “we have always owned one” can conceal capital trapped in non-core capacity.
Breakeven analysis can therefore become a trigger for a strategic capability review.
Ask:
- Is this demand recurring across multiple projects?
- Does ownership create operational advantage?
- Is specialist knowledge built around the asset?
- Would internal availability improve customer response?
- Is the technology stable enough to own?
- Could external market capacity disappear at critical times?
This goes beyond the examination calculation.
The source gives a clean mathematical crossover at 100 days.
ERANORTH extends that into a portfolio question:
At what point does repeated external sourcing indicate that the organisation should own the capability rather than keep buying access to it?
That question matters for manufacturing equipment, test capability, digital platforms, engineering software, temporary facilities and technical specialists.
The answer may still be “continue renting”.
But it should be a strategic choice rather than an accumulation of isolated purchase orders.
Strategic Analysis: The Threshold Should Be Recalculated as Reality Changes
Breakeven decisions are often made once and then forgotten.
That is risky because utilisation, rental rates, maintenance cost and technology can change.
A project that expected 80 days of equipment use may expand to 150.
A lease that looked attractive may become inefficient if maintenance rises or the asset becomes obsolete.
The decision should therefore be revisited when major assumptions move.
This is particularly important across multi-year programs, where temporary requirements can become persistent and market pricing can shift materially.
A simple quarterly or annual review of high-value rented and leased assets can identify where the original sourcing logic no longer holds.
The enterprise benefit is not sophisticated mathematics.
It is preventing yesterday's threshold from becoming tomorrow's hidden cost.
Decision Framework
Use five steps.
1. Calculate the crossover
Identify the usage level where costs are equal.
2. Model utilisation scenarios
Low, expected and high.
3. Add omitted costs
Maintenance, finance, storage, mobilisation, insurance and administration where relevant.
4. Assess operational risk
Availability, reliability, technical support and replacement.
5. Assess strategic reversibility
How much does each option lock the organisation into one technology, capacity or operating model?
The final decision should combine economics and optionality.
From Strategy to Execution
Immediate action: require breakeven analysis for recurring rent-versus-lease decisions above an appropriate threshold.
Medium-term capability building: track actual utilisation against forecast.
Long-term strategic positioning: use utilisation data to decide which assets should become internal capability and which should remain variable external capacity.
This turns procurement history into capital-allocation intelligence.
Signals to Monitor
Watch for recurring rentals above the breakeven threshold, leased equipment with low utilisation, sourcing decisions based only on unit rate, large idle fleets, rapid technology change, or projects keeping equipment “just in case” without recognising the cost of optionality.
Questions for the Leadership Team
- What is the true breakeven usage?
- How certain is the utilisation forecast?
- Which costs are missing from the simple model?
- What happens if demand is materially lower?
- How important is guaranteed availability?
- What capital or flexibility do we sacrifice?
- Is this asset becoming a strategic capability or remaining a temporary need?
Closing Perspective
Breakeven analysis turns procurement into a threshold decision.
But the crossover number is not enough.
The better enterprise choice depends on whether utilisation, uncertainty and strategic flexibility support committing beyond it.
