A fibre laser cutting machine can increase capacity, reduce subcontracting and give a fabrication business greater control over production. However, those benefits do not automatically make every machine a good investment.
Return on investment depends on the work available, the machine specification, operating hours and the costs it replaces. A laser that runs consistently on suitable work may recover its cost far more quickly than a higher-powered machine that spends much of the week standing idle.
The calculation therefore needs to go beyond the purchase price. Installation, finance, labour, assist gas, servicing and material handling all need to be considered alongside the additional output and savings the machine may generate.
What does return on investment mean?
Return on investment measures the financial benefit produced by the machine against the total amount invested in it.
A simple calculation is:
ROI = annual financial benefit ÷ total investment × 100
The annual financial benefit may include subcontracting costs removed from the business, additional profit from increased production, labour savings and reductions in other manufacturing costs.
The total investment should include more than the machine invoice. Depending on the project, it may also include installation, extraction, electrical work, compressed air, gas systems, software, training, automation and material-handling equipment.
This gives a more useful figure than comparing the machine price with projected sales alone.
Start with the work the machine will process
The strongest business cases normally begin with a clear understanding of the work that will be moved onto the laser.
This may be subcontracted cutting that can be brought in-house, work currently completed on a slower machine or additional orders that cannot be accepted because production is already at capacity.
Before calculating a return, the business should identify:
- The number of cutting hours expected each week
- The materials and thicknesses involved
- Current subcontracting expenditure
- Existing production times
- Labour used by the present process
- Expected demand over the next few years
- Any additional work the machine could make possible
A realistic workload is more valuable than an optimistic sales forecast. The calculation should be based on work the company already has or can reasonably expect to secure.
Reducing subcontract laser cutting costs
Bringing subcontracted laser cutting in-house is one of the clearest ways a machine can produce a return.
The potential saving is not simply the amount currently paid to the subcontractor. Internal cutting still has costs, including electricity, gas, labour, consumables and servicing. These must be deducted before treating the remaining difference as a saving.
For example, if a company spends £200,000 a year on subcontract cutting, it should not assume that the whole £200,000 becomes additional profit. The correct comparison is between the complete subcontract cost and the cost of producing the same work internally.
There may also be wider benefits that are harder to express as a single figure. These can include shorter lead times, fewer transport movements, greater control over priorities and the ability to make replacement parts without waiting for an external supplier.
Increased cutting capacity
A fibre laser may allow more parts to be produced during each shift, particularly when it replaces a slower cutting process or older laser technology.
Higher throughput can create value in several ways. Existing orders may be completed sooner, urgent work can be fitted into the schedule more easily and the business may be able to accept work it would previously have turned away.
Cutting speed alone does not determine output. Overall productivity is also affected by:
- Sheet loading and unloading
- Program preparation
- Material availability
- Part sorting
- Exchange-table speed
- Piercing performance
- Machine utilisation
- Downstream production capacity
A fast machine will not achieve its potential if it regularly waits for material, operators or the next process. The ROI calculation should therefore consider the complete production flow rather than the cutting speed shown on a specification sheet.
Labour savings and better use of operators
A new fibre laser does not always reduce the number of employees required. In many cases, the benefit comes from allowing skilled operators to produce more during the same shift.
Exchange tables, automatic nozzle changing, autofocus cutting heads and improved nesting software can reduce manual intervention. Automated loading and unloading may allow the machine to continue processing sheets with less direct operator involvement.
Labour savings should be calculated carefully. If an operator is moved to another productive task, there may be a genuine benefit. If the same labour cost remains and no additional output is created elsewhere, it should not be treated as a complete saving.
The business should also allow for programming, maintenance, material movement and part sorting. These activities remain necessary even where the cutting process itself is highly automated.
Material utilisation can improve the return
Sheet material is often one of the largest costs in fabricated components. Small improvements in nesting efficiency can therefore have a meaningful effect over a full year.
Modern nesting software can arrange parts to reduce scrap, use remnants more effectively and combine different orders on the same sheet. The actual saving depends on part geometry, order quantities and the range of materials being processed.
Material utilisation should be measured against the company’s present performance. It is safer to use historical nesting and scrap data than to assume a fixed percentage improvement across every job.
Improved cut accuracy may also reduce rejected parts and rework, although this depends on correct programming, machine condition and operator practice.
Running costs must be included
A fibre laser has ongoing costs from the first day it enters production. Ignoring them can make the projected return look much stronger than the result the business eventually achieves.
The main operating costs normally include:
- Electricity
- Nitrogen, oxygen or compressed air
- Protective lenses, nozzles and ceramics
- Extraction filters
- Chiller maintenance
- Routine servicing
- Software and support agreements
- Operator labour
Gas consumption can vary substantially according to material, thickness, nozzle size and cutting parameters. A business cutting thin mild steel with compressed air will have a different cost profile from one processing stainless steel with high-pressure nitrogen.
Our guide to fibre laser cutting machine running costs covers the main costs that should be included in the calculation.
Installation costs form part of the investment
The machine price is not always the final amount required to put the system into production.
Site preparation may involve electrical upgrades, extraction, compressed air, assist-gas storage, foundations, safety barriers and changes to material handling. Operator training and commissioning also need to be allowed for.
These costs vary between sites. A factory replacing an existing laser may already have much of the necessary infrastructure, while a first-time buyer may need to prepare the production area from the ground up.
They should be included in the initial investment rather than treated as unrelated factory expenditure. The practical requirements are explained in our guide to fibre laser cutting machine installation.
Automation can improve utilisation
Automation can strengthen the return where it allows the machine to spend more time cutting and less time waiting to be loaded.
Loading systems, unloading systems and material towers can support longer production runs and reduce dependence on manual sheet handling. They may be particularly valuable for businesses operating multiple shifts or producing repeat batches.
However, automation adds to the initial investment and requires enough suitable work to justify it. A loading tower offers limited value if the machine only runs for a few hours each day or frequently processes one-off jobs requiring constant operator involvement.
The calculation should compare the additional cost of automation with the extra productive hours it is expected to create.
Laser power does not guarantee a better return
A higher-powered laser may cut faster and process thicker material, but it is not automatically the most profitable choice.
The machine must be matched to the company’s actual workload. If most production consists of relatively thin sheet, the additional purchase and utility costs of a much higher-powered system may not produce a proportionate financial benefit.
Higher power can make sense where the work includes thicker material, large production volumes or time-sensitive contracts. It may also provide useful capacity for future growth, but that growth should be based on a credible plan.
The differences between common power levels are covered in our comparison of 3kW, 6kW and 12kW fibre lasers.
How to calculate the payback period
The payback period estimates how long it will take for the financial benefit created by the machine to equal the original investment.
A basic calculation is:
Payback period = total investment ÷ annual net financial benefit
If the complete project costs £300,000 and creates a verified annual net benefit of £100,000, the simple payback period would be three years.
This is only a simplified calculation. It does not account for finance charges, tax treatment, depreciation, changes in demand or the time value of money. A formal investment appraisal may also consider net present value, internal rate of return and alternative uses of the company’s capital.
For an initial machinery comparison, however, a realistic payback calculation can help identify whether the proposed machine is commercially viable.
Build the calculation from evidence
The figures used should come from production records wherever possible.
Useful evidence may include subcontract invoices, existing machine hours, operator timesheets, material usage, scrap records, order values and historic lead times.
It is sensible to prepare more than one forecast:
- A conservative case based on existing confirmed work
- An expected case based on normal growth
- A higher-output case showing the result if additional capacity is sold
This gives decision-makers a clearer view of the risk. If the investment only works under the most optimistic scenario, the business case may need to be reviewed.
Consider the cost of downtime
Production reliability has a direct effect on return.
A machine cannot generate revenue while it is waiting for an engineer or replacement part. Buyers should therefore assess service response, spare-parts availability, remote support and the experience of the supplier’s technical team.
The lowest purchase price may not produce the lowest cost of ownership if poor support leads to repeated disruption.
Machine lifespan and long-term reliability should also form part of the decision. Our article on how long a fibre laser cutting machine lasts explains the factors that affect its useful working life.
Finance affects cash flow and overall return
Buying outright, using hire purchase or arranging another form of asset finance will affect cash flow differently.
Finance may allow the machine to begin generating revenue without the business paying the full cost at the outset. It will also introduce interest and fees, which must be included in the total project cost.
The monthly repayment should be compared with the expected monthly benefit produced by the machine. A machine can be profitable over its full life while still creating pressure on cash flow during quieter periods.
The final decision should be reviewed with the company’s accountant or finance adviser using the actual funding terms available to the business.
New and used machines produce different calculations
A used fibre laser may reduce the initial investment and shorten the apparent payback period. It may also carry greater uncertainty around condition, remaining warranty, software support and future repair costs.
A new machine generally provides the latest controls, a full warranty and a more predictable starting point, but requires more capital.
The right choice depends on the workload, available budget and the importance of production continuity. Our guide to new and used fibre laser cutting machines examines the main differences.
Questions to answer before investing
Before approving the purchase, the business should be able to answer the following questions:
- Which existing work will be processed on the machine?
- How many productive hours will it run each week?
- What subcontracting expenditure will genuinely be removed?
- What additional work can the business realistically secure?
- Which materials and thicknesses will be cut most frequently?
- What are the expected gas, energy and labour costs?
- Does the factory need electrical, extraction or gas-system upgrades?
- Is automation required immediately or can it be added later?
- Can downstream processes handle the additional output?
- What technical support is available if the machine stops?
If these questions cannot be answered with reasonable confidence, the proposed return is likely to be based on assumptions rather than a firm production plan.
Choosing a machine that can produce a return
The best investment is not necessarily the cheapest machine or the one with the highest laser power.
It is the machine that matches the company’s current workload, provides enough capacity for realistic growth and is supported throughout its working life.
Machine specification should be based on material range, thickness, sheet size, production volume, automation requirements and available factory space. Our guide to choosing the right fibre laser cutting machine covers these points in more detail.
A carefully specified machine with a clear workload can become a valuable long-term production asset. A poorly matched machine may increase capacity on paper without delivering the financial return expected from it.
Frequently Asked Questions
How do you calculate the ROI of a fibre laser cutting machine?
Calculate the annual net financial benefit produced by the machine and divide it by the total project investment. The net benefit should include genuine savings and additional profit after electricity, gas, labour, servicing and other operating costs have been deducted.
How quickly can a fibre laser cutting machine pay for itself?
There is no standard payback period. It depends on the machine cost, operating hours, subcontract expenditure, production volume, material mix and the profit generated from additional capacity.
Can bringing laser cutting in-house reduce costs?
It can reduce subcontracting, transport and lead-time costs where there is enough suitable work to keep the machine productive. Internal running costs must still be deducted when calculating the saving.
Does automation improve fibre laser ROI?
Automation can improve ROI when it increases productive cutting hours, reduces loading delays or supports unattended production. It is less likely to be justified where production volumes are low or work changes constantly.
Is a higher-powered fibre laser always a better investment?
No. Higher power only produces a stronger return when the workload benefits from the additional cutting speed or thickness capacity. An oversized machine may add cost without creating enough extra output.
Should installation costs be included in the ROI calculation?
Yes. Electrical work, extraction, gas systems, compressed air, training, commissioning and material handling all form part of the investment required to put the machine into production.
How do running costs affect the payback period?
Higher electricity, gas, consumable and servicing costs reduce the annual net benefit and lengthen the payback period. Estimates should be based on the materials and thicknesses the business expects to process.
Should a fibre laser be purchased outright or financed?
The right option depends on available capital, cash flow, finance costs and the company’s wider investment plans. Any interest and fees should be included when comparing the complete cost of each option.
Can a used fibre laser provide a better return?
A used machine may require less initial capital, but its condition, service history, warranty and likely repair costs must be considered. A lower purchase price does not always result in a lower total cost of ownership.
What is the biggest factor affecting fibre laser ROI?
Machine utilisation is one of the most important factors. A correctly specified machine processing profitable work for a high proportion of the available production time is more likely to produce a strong return.
