Quick answer
To test whether new equipment will pay for itself, estimate the extra monthly profit it will create or the costs it will save, subtract its running costs, and compare the result with the monthly finance repayment. Then work out the payback period. If the equipment comfortably covers its repayments and pays back well within its useful life, borrowing to buy it can make sense.
Key points
- Start with the extra profit or savings, not the price.
- Include running, maintenance and training costs.
- Compare net monthly benefit with the finance repayment.
- Payback should be well inside the asset's useful life.
Checklist
- Extra jobs or output estimated
- Cost savings estimated
- Running and maintenance costs included
- Finance repayment calculated
- Payback period worked out
- Downside case tested
New equipment is one of the most common reasons businesses borrow, and one of the most common sources of regret. A machine that sits idle half the week still has repayments every month. A simple payback test, done before you sign, separates equipment that will earn its keep from equipment that will quietly drain cash.
Step 1: Estimate the benefit
Most equipment creates value for a business in two broad ways:
- Extra revenue: more jobs, larger contracts, new services or faster turnaround.
- Cost savings: less labour, fewer subcontractors, lower maintenance on old gear, less waste or energy.
Base estimates on evidence: jobs you currently turn away, quotes that require the equipment, time sheets showing hours spent on manual work. Be conservative about how quickly the benefit will arrive.
Step 2: Count the full cost of owning it
| Cost | Examples |
|---|---|
| Finance repayments | Monthly repayment on the loan or lease |
| Running costs | Fuel, power, consumables |
| Maintenance | Servicing, parts, repairs |
| Insurance and registration | Where applicable |
| Training and setup | Staff time, installation, software |
Step 3: Calculate net monthly benefit
Net monthly benefit = extra monthly profit + monthly savings − running, maintenance and other monthly costs.
Then compare it with the monthly finance repayment. If the net benefit comfortably exceeds the repayment, the equipment is likely to pay its way. The repayment coverage calculator helps check the effect across all your commitments.
Step 4: Work out the payback period
Payback period = purchase cost ÷ net monthly benefit (before finance).
The payback should be comfortably shorter than the asset’s useful life. If a machine will last five years and pays back in eighteen months, the case is strong. If it pays back in four and a half years, there is little margin for error.
Step 5: Test the downside
Reduce your revenue estimate and increase your cost estimate. Does the equipment still cover its repayments? If the answer depends on everything going right, consider a smaller or used machine, a lease with an upgrade path, or waiting until demand is proven. Our guide to leasing or buying and financing used equipment cover those alternatives.
Choose the right finance
If the numbers stack up, equipment finance usually suits, with the asset as security and a term matched to its working life. Avoid funding equipment from a line of credit or short-term loan, which can create repayment pressure before the benefit arrives.
An illustrative example
A made-up automotive workshop is considering an alignment machine. It currently refers alignment work elsewhere and estimates it could do a steady number of alignments per week at a conservative margin, plus save time on related repairs. After running costs, the net monthly benefit comfortably exceeds the finance repayment, and payback is well inside the machine’s expected life. Even with half the expected jobs, repayments are covered. The workshop proceeds.
Signs the purchase is premature
- Demand is hoped for rather than evidenced.
- The machine would be idle most of the week.
- The repayment is only covered in a best-case scenario.
- A cheaper used option or subcontracting would meet current demand.
Revisit after purchase
Track actual benefit against your estimate for the first six months. If it is falling short, adjust: market the new capability, change pricing or reassign work to the machine.
Counting your own time honestly
Owners often value their own time at zero when assessing equipment, which can make manual work look cheaper than it is. If a machine would free several hours of your week, ask what you would do with those hours: quote more jobs, manage staff, rest. If the freed time would genuinely produce income or prevent burnout, include a realistic value. If it would simply be absorbed, leave it out.
Capacity and demand
Equipment only creates value when there is work for it. Before buying, check that you have the demand, the staff and the space to use it. A second machine without a second operator, or a larger truck without larger contracts, adds repayments without adding revenue. Sometimes the right first step is winning the work, then buying the equipment.
Comparing new, used and outsourced
Run the same test for a new machine, a used one and continuing to outsource the work. Used equipment may pay back faster despite higher maintenance; outsourcing may remain cheaper until volume grows. Putting the three options side by side often makes the decision obvious.
Ready to finance equipment that pays its way?
If your numbers show the equipment will earn its keep, make one enquiry. There is no credit check when you first enquire, a real person reviews it and your details go to one lending partner rather than a list. Include the equipment, its price and how it will be used in your enquiry.
Frequently asked questions
What is a payback period?
The time it takes for the extra profit or savings from an investment to cover its cost. Shorter payback means lower risk.
How do I estimate extra revenue from equipment?
Base it on real demand: jobs you currently turn away, contracts that require the equipment, or capacity you can fill. Avoid assuming the machine will run flat out from day one.
Should I include tax benefits in the calculation?
You can, but test the decision without them first. Tax benefits should be a bonus, not the reason the numbers work.
What if the equipment only saves time?
Time saved has value if it is used: more jobs, less overtime, fewer subcontractors. If the saved time is not used productively, the saving is smaller than it looks.
Is leasing better if the payback is uncertain?
Leasing or a shorter-term commitment can reduce risk when demand is uncertain, though it may cost more overall.
What is a reasonable payback period?
It depends on the asset's life and your risk appetite. The key test is that payback is comfortably shorter than the asset's useful life.
How do I test a downside scenario?
Reduce your revenue estimate or increase costs and see whether the repayment is still covered. If not, reconsider the size of the purchase or the finance structure.
Should I include depreciation in the payback test?
The simple payback test uses cash: purchase cost against net monthly benefit. Depreciation matters for tax and accounting, which your accountant can add to the picture.
What if the equipment is required by a contract?
If a contract requires the equipment and the contract revenue clearly covers it, the payback case can be strong. Check the contract length against the finance term.
Can I use the payback test for vehicles?
Yes. Estimate the extra work or savings the vehicle enables, subtract running costs and compare with the repayment. Include fuel, registration, insurance and servicing.
