Rent vs Buy: A Decision Framework for Used Heavy Equipment

There is no universally right answer. The right answer for a 200-hour-per-year contractor is different from the right answer for a 1,500-hour-per-year operation. Here is the framework we use when buyers call us asking whether they should buy or keep renting.

The single most important number

Hours per year is the variable that drives everything else. Estimate honestly. If you are not sure, look at your operations:

• Under 400 hours/year: renting is almost always cheaper. The depreciation, insurance, storage, and maintenance overhead of ownership does not pay back at this utilization.
• 400 to 800 hours/year: gray zone. Depends on equipment type and your access to good rental supply.
• Over 800 hours/year: buying almost always wins. You are paying rental margins for hours you could be amortizing into your own asset.
• Over 1,200 hours/year: buying used is the cheapest dollar-per-hour you will ever spend.

The numbers behind the rule

Rough monthly rental rates we see in the Northeast US, with mid-size used equipment (mid-life condition):

Equipment	Monthly rent	Used buy (good condition)	Break-even (months)
35-ton excavator	$11K-$14K	$160K-$200K	14-18 months
Mid-size screener	$8K-$11K	$180K-$240K	22-28 months
Horizontal grinder	$18K-$25K	$400K-$600K	22-28 months
Crawler dozer (D6 size)	$9K-$12K	$140K-$190K	14-18 months
Wheel loader (3-yard)	$7K-$10K	$90K-$140K	12-16 months

Break-even assumes you can keep the machine working at average utilization. Empty time still counts against you in ownership economics.

What rental costs miss

The headline rental rate is only part of the cost:

On top of monthly rent, factor in:

• Delivery/pickup — $500-$3,500 per move depending on size and distance
• Insurance damage waiver — often $200-$800/month if you do not have your own coverage
• Fuel — your responsibility under most agreements
• Wear and damage assessments at return — variable, sometimes surprising
• Operator if renting unmanned — your own labor cost

Real all-in monthly rental of a 35-ton excavator delivered, insured, and fueled for a month of use is typically $14K-$18K — not the $11K-$14K headline.

What ownership costs really include

Buyers who run the math against the headline purchase price miss the full picture:

On top of purchase price, budget for:

• Insurance — 0.8% to 1.5% of value annually
• Storage — yard space, security, weather protection
• Routine maintenance — varies, but plan 8-12% of purchase price annually for equipment in active use
• Tires/tracks/undercarriage — large machines eat $20K-$80K in undercarriage over a normal ownership cycle
• Major component replacement — engine rebuild, hydraulic pump, swing motor. Plan one major event per 10,000 operating hours.
• Resale risk — what you can actually sell it for in 5 years is not what it cost you minus a straight-line depreciation schedule

True annual cost of ownership for a $150K used mid-size excavator at moderate use is roughly $25K-$40K. That includes maintenance, insurance, undercarriage, and depreciation against realistic resale.

The decision tree

Walk through these questions:

1. Will you use it more than 800 hours this year? If yes, lean buy.
2. Do you have storage and basic maintenance capacity? If no, weight rentals more heavily — storage and minor wrenching costs eat into ownership savings.
3. Is this a permanent operational need or a one-time project? Project work = rent. Permanent fleet = buy.
4. Can you finance the purchase at under 10% APR? If yes, ownership math gets even better. Cash-rich buyers should think about opportunity cost.
5. How easy is rental supply in your area? Tight rental markets push toward ownership. Available rental markets reduce the urgency to buy.

Common scenarios

Scenario 1: Small land clearing contractor, 600 hrs/yr on a mid-size excavator
Verdict: borderline. If rental supply is reliable and you can predict your jobs 60 days out, rent. If you turn down jobs because no rental is available on short notice, buy.

Scenario 2: Aggregate operation, 1,500 hrs/yr on a screener
Verdict: buy. At this utilization, rental margins are eating $80K+ per year you could be putting into an owned asset.

Scenario 3: Recycling startup, year 1 cash-tight, projected 900 hrs/yr
Verdict: rent for 6-12 months to validate the business, then buy used. Owning an underutilized $200K machine while you are figuring out the business is a fast way to fail.

Scenario 4: Established forestry contractor with multiple crews, 1,800 hrs/yr on each grinder
Verdict: buy and run a planned replacement cycle. Trade in or sell at 8,000-10,000 hours and roll the equity into the next unit.

What we tell buyers at RPG Equipment

We sell used equipment, so it would be self-serving to say "always buy." We do not say that. We tell buyers: be honest about your hours, factor in the full cost of both sides, and make the call your business needs — not the call the salesperson wants.

If you want a second opinion on a specific decision, call (508) 625-9271. We will tell you when renting is the smarter call, even if it means losing a sale.
