- Equipment cost = $1800.00 (estimate)
- 8Hp Diesel motor (entry model) OR 3Kw single-phase electric motor pellet mill operating at max. 80% power
- Production output about 20kg/hr (max. 30kg/hr but we will use 20kg/hr for this illustration)
- Cost includes lubricant, 1 extra set of roller/die & one moisture content tester
- Cost includes shipping, custom and delivery charges
- Raw material cost = $375.00 (estimate)
- 1 ton (1000kg) of fine sawdust cost about $60.00 (including delivery)
- 1kg of sawdust can produce about 0.8kg of wood pellets (20% leave the compression chamber as unprocessed sawdust waste which can be reused)
- To produce 5000kg of wood pellets, we need about 5000/0.8 = 6250 kg of sawdust
- Cost of 6250kg of sawdust cost = 6250kg/1000kg x $60 = $375.00

- Electricity cost = $189.00
- Grid power = $0.30 for 1kWh (average)
- Number of hours to produce 5000kg of wood pellets = 5000/20 = 250 hours
- Add 5% more of 250 hours for preparing of die/maintenance = 12.5 hours
- Electric motor operates at max. 80% of 3Kw
- Therefore, estimate electricity cost = (250 + 12.5) hours x $0.3/kWh x (0.8 x 3Kw) = $189.00

- Diesel fuel cost = $1102.50
- Diesel per litre around $1.4 (estimate)
- Diesel fuel consumption (estimate) = est. 3L per operation hour
- Number of hours to produce 5000kg of wood pellets = 5000/20 = 250 hours
- Add 5% more of 250 hours for preparing of die/maintenance = 12.5 hours
- Therefore, estimate diesel fuel cost = (250 + 12.5) hrs x 3L/hr x $1.4/L = $1102.5

| Estimate cost of producing 5000kg wood pellets at home (Using single-phase electric motor home pellet maker)
= item 1 + item 2 + item 3
= $1800 + $375.00 + $189.00
= $2364.00
|
Estimate cost of producing 5000kg wood pellets at home (Using diesel engine motor home pellet maker)
= item 1 + item 2 + item 3
= $1800 + $375 + $1102.60
= $3277.50
