Tools commonly used alongside this calculation
Labor Burden Calculator
Calculate the fully burdened labor rate for construction. Add payroll taxes (FICA, FUTA, SUTA), workers' comp, insurance, and benefits to a base wage to get the labor burden % and the true cost per productive hour for accurate bids. Free, no sign-up.
Man-Hours Calculator
Estimate construction labor man-hours, crew duration, and cost. Enter a quantity and a production rate or labor unit, your crew size, and a productivity factor to get total man-hours, work days, and labor cost. Free, no sign-up.
Change Order Calculator
Price a construction change order with overhead, profit, and bond markup. Add labor, material, equipment, and subcontractor costs to get the total price, the markup added, and the true margin vs markup. Free, no sign-up.
Explanation
An equipment rent vs buy calculator compares the fixed cost of owning a machine against the per-use cost of renting it, so you can see which is cheaper at your real utilization. Owning carries the same annual cost whether the machine sits or works; renting only costs you on the days you need it. The decision turns on how much you actually use the equipment — the break-even is the number of days per month where the two costs meet.
How the rent vs buy comparison works
Ownership cost is more than the loan payment. It is the depreciation you lose, the cost of the capital tied up in the machine, plus maintenance, insurance, storage, and taxes you carry that a rental house would otherwise cover. Dividing the annual total by twelve gives a fixed monthly cost to set against the rental. Equipment is one line of a job cost — pair this with the labor burden calculator for the labor side of the same bid.
capital cost/yr = (price + salvage) ÷ 2 × rate
ownership/yr = depreciation + capital + maintenance + insurance
break-even days = (ownership/yr ÷ 12) ÷ daily rental rate
| Term | Meaning |
|---|---|
| depreciation | Value lost over the ownership period |
| capital cost | Interest or opportunity cost on the average investment |
| daily rental rate | Rate converted to a per-day basis (weekly ÷ 5, monthly ÷ working days) |
| break-even days | Days per month of use where owning equals renting |
The 60% rule and break-even utilization
The industry rule of thumb is the 60% rule: if you use a machine more than about 60% of the available working days — roughly 12 to 14 days a month — owning usually beats renting. Below 40% utilization, renting is almost always cheaper and keeps your capital free. The 40–60% band is the judgment zone where the exact rates, tax treatment, and how reliably you can keep the machine busy decide it. When you forecast how many days the work needs the machine, the man-hours calculator helps turn the scope into crew days.
| Utilization | Guidance |
|---|---|
| Below 40% | Rent — ownership sits idle too often |
| 40–60% | Evaluate — weigh rates, taxes, and reliability of use |
| Over 60% | Buy — owning typically delivers better ROI |
Costs beyond the purchase price
Owning adds costs the sticker never shows: transport to and from job sites, secure storage, the downtime when a machine is in the shop, and the capital you cannot deploy elsewhere. On the other side, buying lets you depreciate the asset and may qualify for a Section 179 deduction of the full purchase price in the year of purchase, a real tax advantage renting does not offer. This tool compares typical ownership and rental costs; the rental rate is converted to a daily basis (weekly ÷ 5 working days, monthly ÷ your working days), and fuel and the operator are excluded because they apply either way. Confirm your actual rates, financing terms, and tax position before deciding.
