Buy it or hire it in? The numbers that decide

Divide the annual net cost of owning the machine by the daily rate to hire the same thing in. That is the number of days a year at which owning starts to win. For the $110,000 telehandler below it is 95 days — about one working day in three. Below that, hire in. Above it, owning wins by more the further above you go. But do not buy at the crossover: the downside if the work does not arrive is far larger than the upside if it does.

Ask the question properly

"Should I buy it or hire it in?" is really three questions wearing one coat, and people argue past each other because they are answering different ones.

  • How many days a year will I need it? This decides the arithmetic, and it decides it almost on its own.
  • How certain am I about that number? This decides how much of a margin you need before ownership is worth the risk.
  • What else could that capital do? A deposit spent on a telehandler is a deposit not spent on the machine you are short of every week.

Get the first one right and the other two become judgement calls you can actually make. Get it wrong and no amount of careful thinking about the other two will save you.

What owning really costs

Ownership costs are overwhelmingly fixed. Once the machine is on your yard, the finance payment, the insurance, the registration and the depreciation all run whether it works two hundred days a year or twenty. Only maintenance, fuel and tyres vary much with use, and on many machines they are a small share of the total.

Hiring in is the mirror image: almost entirely variable. You pay for the days you use and nothing on the days you do not. That single difference is the whole of the rent-versus-buy decision. You are choosing between a low cost per day with a high commitment, and a high cost per day with no commitment at all.

Worked example

A $110,000 telehandler, kept five years

Cash movement over five yearsAmount
Deposit paid on day one−$33,000
60 loan instalments at $1,561−$93,677
Maintenance, insurance, registration, overhead share−$42,800
Sold at the end of year five+$46,000
Net cost of owning it for five years−$123,474

That is $24,695 a year, and it barely moves whether you use the machine every day or leave it parked.

The crossover

Hiring the same class of machine in costs, say, $260 a day including delivery on a short hire. Owning becomes cheaper than hiring at:

$24,695 ÷ $260 = 95 days a year.

Below roughly 95 days — about one working day in three — hiring in wins. Above it, owning wins, and the further above it you go the wider the gap becomes.

Where the crossover lands for you

The number 95 is specific to that machine, that finance deal and that hire rate. What is general is the method: divide your annual net cost of ownership by the daily hire-in rate. Two things move the answer a long way.

Annual cost of owningHire-in at $200/dayat $260/dayat $350/day
$15,00075 days58 days43 days
$25,000125 days96 days71 days
$40,000200 days154 days114 days
$60,000300 days231 days171 days

Read the bottom row carefully. If a machine costs $60,000 a year to own and you can hire the same thing for $260 a day, you would need it on site 231 days a year — effectively every working day — before ownership pays. Very few contractors need any single machine that much. This is precisely why the large, expensive, occasional-use items are the ones that should almost always be hired, and the cheap, everyday items are the ones worth owning.

The part the arithmetic misses

Suppose your crossover is 95 days and you expect to need the machine 120 days a year. Ownership wins by about $6,500 a year. Now ask what happens if the two contracts you were counting on slip a quarter, and you use it 70 days instead. You lose about $6,500 the other way, and you still owe the same instalment every month for the remaining four years. The upside is capped and the downside is not.

That asymmetry is why sensible operators do not buy at the crossover. They buy when the expected use is comfortably above it — half as much again is a common rule — and hire in everything else. The margin is not a fudge factor, it is the price of not being locked in.

Things that push the answer towards owning: steady, predictable, year-round work; a machine you can also cross-hire to other contractors on idle days; a strong second-hand market for that model; long finance at a good rate; and enough scale to service it properly in-house.

Things that push it towards hiring in: lumpy or seasonal demand; a machine you need in a size you cannot predict; fast-moving technology; anything requiring specialist certification, training or inspection; and a business where capital is the binding constraint on growth.

The question people forget: what else could that money do?

The $33,000 deposit is not the only cost of owning. It is $33,000 you cannot use for anything else, and the right comparison is not against zero — it is against the best alternative use.

For a rental business that alternative is usually obvious: another machine, in a class where you are turning work away. If a second unit of your busiest class would return 25 per cent a year on its cost, then a telehandler returning 12 per cent is not a good investment even though it is a profitable one. Being profitable and being the best use of the money are different tests, and only the second one grows the business.

For a contractor the alternative is often working capital — the ability to take on a bigger job, or to survive a customer paying late. Capital tied up in a machine that works a third of the year is capital not available on the day you need it most.

The options between renting and buying

The choice is rarely binary, and the middle ground is where a lot of well-run businesses live:

  • Long-term hire. Three, six or twelve months at a heavily reduced monthly rate. You get most of the cost advantage of ownership without the residual-value risk or the balance-sheet commitment. Ideal when the work is certain but only for a season.
  • Rent to own. Part of the hire charge is credited against the purchase price if you decide to buy. You pay a premium for the option, which is fair — an option has value. Worth it when the deciding factor is a contract you have not yet won.
  • Buy and cross-hire. Own the machine, use it for your own work, and hire it out to other contractors on the idle days. This is how a contractor's crossover point drops dramatically, and how many rental businesses started. It also brings maintenance, insurance and administration you may not want.
  • Buy used. A three-year-old machine costs far less and depreciates far more slowly in percentage terms, which pulls the crossover point down sharply. It costs more to maintain and is harder to finance.

One argument for owning that the five-year model hides

In the example, the loan finishes at month 60. If you keep the machine for another three years, those years cost you only maintenance, insurance and overhead — roughly $8,500 a year instead of $24,695. The crossover for years six to eight falls from 95 days to about 33.

That is a real and often decisive advantage, and it is why fleets that hold machines eight or ten years can price below fleets that renew every five. The catch is that it only works if the machine is still reliable, still marketable, and still the size your customers ask for. Deciding to keep a machine past the loan is a bet on the next three years being like the last five, which is exactly the bet that a well-run fleet reviews rather than assumes.

Common questions

What is the break-even point for buying versus renting equipment?

Annual net cost of ownership divided by the daily hire-in rate. Net cost of ownership means the deposit plus all the instalments plus running costs, less what you will get when you sell, spread over the years you hold it. On a $110,000 telehandler costing $24,695 a year to own against a $260 hire-in rate, the crossover is 95 days a year. Cheaper machines cross over sooner; expensive occasional-use machines almost never cross over at all.

Is it cheaper to rent or buy heavy equipment?

It depends entirely on how many days a year you need it, and the answer flips sharply. Ownership costs are almost all fixed, so the cost per day of use falls the more you use the machine. Hiring in costs the same per day whether you need it twice or two hundred times. There is no general answer, only a crossover point, and it is different for every machine and every finance deal.

Does leasing change the answer?

It changes the cash profile and the balance-sheet treatment more than the underlying economics. An operating lease is closer to long-term hire: you avoid residual-value risk and pay a premium for it. A finance lease is closer to buying with debt. Work out the total cash out over the term in each case, including any balloon payment and end-of-lease condition charges, and compare like with like.

What if I can hire the machine out to others when I am not using it?

That changes everything, because it converts idle days into revenue and pulls the crossover point down sharply. It also brings maintenance, insurance, administration, damage disputes and a duty of care you may not want. Model it as two separate income streams — your own use and third-party hire — and be conservative about the second, because it is the one that disappears first in a downturn.

Should I buy used instead?

Often, yes. A three-year-old machine costs far less and, on a declining-balance curve, loses a smaller number of dollars each year than a new one, which pulls the crossover point down considerably. Against that, maintenance costs more and is less predictable, finance is harder and dearer, and downtime risk is higher. It suits businesses with their own workshop far better than those without.

Model the purchase before you commit

Enter the machine, the finance and the days you expect to use it. You get the annual cost of ownership, the payback month and the return — the three numbers the decision rests on.
