The math, shown transparently

No black box. Here is exactly what the calculator computes. (Source: Cat Performance Handbook for fuel burn rates, Fecon/Rayco catalogs for teeth pricing)

// Daily cost: sum of all fixed and variable costs

daily_cost = machine_payment/mo / working_days

+ insurance/mo / working_days

+ fuel_gal_per_hr x fuel_cost x 8 hrs

+ teeth_per_hr x teeth_cost x 8 hrs

+ operator_wage x 8 hrs

// Day rate: cost divided by inverse of margin

day_rate = daily_cost / (1 - target_margin / 100)

Worked example

Mid-size machine, $3,000/mo payment, 20 working days, 5 gal/hr at $4/gal, 3 teeth/hr at $20, $30/hr operator, 30% margin:

machine = $3,000 / 20 = $150/day

fuel = 5 gal x $4 x 8 hrs = $160/day

teeth = 3 x $20 x 8 hrs = $480/day

labor = $30 x 8 hrs = $240/day

daily_cost = $150 + $160 + $480 + $240 = $1,030/day

day_rate = $1,030 / 0.70 = $1,471/day

Why most operators undercharge

Teeth are the hidden killer. At 3 per hour and $20 each, that is $480 per day in teeth alone. Most operators remember fuel and labor but forget teeth, insurance, and the days they do not work.

A machine that sits idle still costs you the monthly payment and insurance. If you work 20 days a month but pay for 30, your real daily cost is 50% higher than what a simple calculation shows. That is why the calculator divides monthly fixed costs by working days, not calendar days.

The margin is not pure profit either. It covers callbacks, weather days, quoting time, bookkeeping, and the truck that gets you to the job. A 30% margin sounds generous until you account for the 10 days a month you are not billing.

Frequently asked questions

How much should I charge per day for forestry mulching?

Most forestry mulching contractors charge between $1,500 and $3,500 per day depending on equipment size, operating costs, and target profit margin. A mid-size excavator with mulcher head running 8 hours burns through $1,000-$1,500 in daily operating costs (fuel, teeth, labor, insurance, machine payment). Adding a 30-40% profit margin puts the day rate at $1,500-$2,500 for smaller machines and $2,500-$3,500 for large dedicated mulchers.

What is a good profit margin for land clearing?

Industry-standard profit margins for forestry mulching and land clearing range from 25% to 45%. New contractors often start at 25-30% to win jobs, while established operators with a reputation and backlog command 35-45%. Below 25% leaves too little buffer for unexpected costs (broken teeth, hydraulic issues, weather delays). The calculator shows you both break-even and your chosen margin rate so you can decide what works for your market.

How do I calculate fuel cost per day for a mulcher?

Multiply your fuel burn rate (gallons per hour) by hours worked per day, then by your local diesel price. A mid-size excavator with mulcher burns 4-6 gallons per hour (Cat Performance Handbook data). At $4.00/gallon and 8 hours, that is $128-$192 per day in fuel. Large dedicated mulchers burn 6-8 gallons per hour, costing $192-$256 per day.

How much do mulcher teeth cost per day?

Mulcher teeth (carbide tips) cost $15-$30 each and a typical mulcher consumes 2-4 teeth per hour depending on vegetation and rock content. At $20/tooth and 3 teeth/hour for 8 hours, that is $480 per day in consumables. Rocky ground accelerates wear significantly. Some operators report 5-6 teeth per hour in rocky conditions.
