Forestry Mulcher Rent vs Buy Calculator
Should you buy a mulcher or keep renting? Enter your utilization and financing and get the honest break-even — built by a company that does both sides of this math for a living.

Planning math, not financial or tax advice — Section 179 and bonus depreciation can materially change ownership economics. Run the final numbers with your accountant.
How the break-even is calculated
Ownership cost per year = depreciation + financing interest + insurance + wear parts. Depreciation spreads the difference between purchase price and expected resale across the years you keep the machine. Interest uses a standard amortization on the financed balance (up to a 5-year term). Insurance is estimated at 2.5% of machine value per year for inland marine plus liability. Wear parts and maintenance — teeth, knives, filters, hydraulics — are charged per working week ($2,500/week high-HP, $1,800 mid-size, $1,200 skid steer class), because mulchers wear when they work, not when they sit. Renting is simply the published weekly rate times your weeks of work: no capital, no depreciation, wear parts and service included. The break-even is the number of working weeks per year where the two lines cross. Default purchase prices are typical new-machine figures — edit them to match your actual quote. Resale defaults are deliberately conservative: dedicated forestry mulchers are a thin, specialized resale market — they take a major depreciation hit the day they leave the dealer, and finding a buyer can take months. If you would not run the machine to the end of your horizon, weight the math further toward renting. This is planning math, not financial or tax advice: Section 179 expensing and bonus depreciation can materially improve the ownership side, so run the final decision with your accountant.

How to read the break-even
The calculator finds the annual utilization — how many weeks a year the machine actually works — at which owning costs less than renting. Below that number, renting wins on pure cost. Above it, ownership starts to pay, provided you can keep the machine fed with work you control.
The line most buyers underestimate: resale
Depreciation is the largest item in the ownership column and it is heavily front-loaded. Selling these machines can be tough — the buyer pool is small, regional, and particular about hours and head condition — and a machine purchased new takes a major depreciation hit almost immediately. If your plan depends on recovering most of the purchase price in three years, stress-test that assumption before you let it drive the decision.
What ownership adds that the sticker price does not show
Financing interest. Insurance carried year-round rather than only on rental days. Wear parts, which are genuine consumables in heavy brush. Scheduled service and the shop time around it. Transport equipment, or hired hauling every time the machine moves. And the cost of downtime, which on a one-machine fleet is total: when your mulcher is down, your production is zero. A rental fleet absorbs all of that and prices it into the week.
When renting keeps winning
Seasonal or project-driven work. An unpredictable pipeline. Jobs that need different machine classes — a high-HP dedicated machine this month and a CAT 275 XE next. Renting also keeps you on current equipment without owning last season’s, and it moves breakdown risk off your balance sheet. Current pricing is on the rental rates page.
When buying starts to make sense
Consistent, near-year-round utilization on work you originate yourself. An operator on staff who already knows the platform. A shop or a supplier relationship that can turn wear parts around without stalling a job. If all three are true, the math usually favors ownership, and the calculator will show you roughly where the line sits. If only one or two are true, run the numbers honestly before signing.
The third option people forget
Neither renting nor buying is mandatory. If the constraint is operator availability rather than machine cost, hiring turnkey mulching at $4,000 per day plus transport for high-HP work, or $3,000 per day including transport for skid steer work, often beats both.
