How to Price Sawn Lumber: From Production Cost to the Right Selling Price

Most sawmills operating with tight margins share a common problem: they know the price they charge, but they don't know the cost that price needs to cover. This ignorance is expensive — and silent.

Pricing sawn lumber based only on the local "market price," without breaking down actual production costs, is a strategy that works when margins are comfortable — and fails when input costs rise, log prices increase, or competition intensifies.

In this article you'll learn the complete cost structure of a sawmill, how to calculate the cost per m³ sawn, and how to use that information to set prices that guarantee real profitability — not just cash flow.

The most common pricing mistake in sawmills

The mistake is simple: copying the competitor's price or using the "market price" as a reference without knowing whether that price covers your specific costs.

Two neighboring sawmills can have completely different cost structures: one buys cheaper logs by having direct access to forest producers; the other has more efficient equipment with lower kerf. Same dimensions, similar market prices, very different internal costs — therefore, very different margins.

The correct starting point is always cost, not the neighbor's price.

The components of sawmill production cost

1. Raw material cost (logs)

The most relevant component — typically representing 50–70% of total production cost. The log cost per m³ of sawn lumber depends on two factors:

• The log purchase price (per m³ of log)
• The conversion yield (% of sawn lumber per m³ of log)

Formula for raw material cost per m³ sawn:

Raw material cost = Log price (per m³) ÷ Conversion rate

Example: log at $50/m³, 55% conversion → Raw material cost = 50 ÷ 0.55 = $91/m³ sawn

This formula reveals something fundamental: each percentage point of yield directly impacts raw material cost. Raising conversion from 55% to 60% on the same log reduces raw material cost from $91 to $83/m³ — a saving of $8/m³ without changing any input price.

2. Direct operating costs

• Direct labor: saw operators, yard helpers, graders — including full payroll burden.
• Maintenance and blades: band saw blade changes, sharpeners, carriage and guide maintenance.
• Electric power: band saw motors consume 15–75 kW depending on size. Calculate in kWh per m³ sawn.
• Fuels: forklifts, yard loaders.

3. Fixed and structural costs

• Equipment depreciation: the saw, the carriage, conveyors.
• Space rental or opportunity cost: shed, log yard, drying area.
• Indirect labor: management, administration, sales.
• Insurance, taxes, accounting.
• Financing costs: if logs were purchased on credit or equipment is financed.

Calculating cost per m³ sawn

Total cost = Raw material cost + Direct operating costs + Fixed costs (for the period)

Cost per m³ = Total cost ÷ Volume produced (m³)

Practical example

Sawmill producing 80 m³ of sawn lumber per month:

Cost per m³ = $10,590 ÷ 80 = $132/m³

If the local market price for the produced dimensions is $152/m³, the gross margin is $20/m³ — or 13.2%. If the price falls to $140/m³ due to competitive pressure, the margin drops to $8/m³ — and any cost increase turns into a loss.

Pricing strategies for sawmills

1. Cost-plus pricing

The simplest and safest strategy for smaller sawmills:

Price = Cost per m³ + Desired margin (%)

If cost is $132/m³ and you want a 20% margin → Price = $132 × 1.20 = $158/m³

2. Dimension-differential pricing

Not all dimensions have the same production cost. A 6x12 beam requires a larger (more expensive) log, has more kerf in lateral cuts, and uses more machine time per m³ than a 2x4 stud. Pricing them at the same $/m³ distorts your margin.

3. Volume and relationship pricing

For customers who buy regularly and in large volumes, a small concession on price per m³ can be offset by reduced selling costs (less prospecting, better production predictability, lower per-delivery logistics costs).

4. Residue revenue as margin contribution

Sawdust and chips generated in the process have commercial value — for ceramics, poultry farming, energy generation. Quantifying this additional revenue and subtracting it from production cost reduces the net cost per m³ sawn and increases competitiveness.

The impact of conversion yield on pricing

This is the point most sawmills underestimate: conversion yield is the most powerful lever in pricing.

A 10-percentage-point improvement in yield (from 50% to 60%) reduces raw material cost by $17/m³ — without changing the log price, without adding employees, without any investment beyond more precise cut planning.

That's exactly the role of cut optimization in SawOptima: calculating the piece arrangement that maximizes yield within each log, reducing raw material cost per m³ sawn — which directly translates into higher margin or more competitive pricing.

Building your price list

With the cost per m³ calculated and desired margin defined, the final step is building a price list by dimension that reflects cost differences and market value perception.

A well-structured price list should include:

• Price per m³ for each main dimension
• Price per linear meter or per piece (for customers who buy that way)
• Payment terms and possible volume discounts
• Note on nominal vs. actual dimension delivered
• Lead time and freight conditions

Reviewing the price list monthly — or whenever log prices fluctuate more than 5% — is a minimum management practice for sawmills that want to protect their margin.

Conclusion

Pricing sawn lumber is an exercise that begins with honesty about costs. Without knowing what it costs to produce each m³, any price charged is a guess — sometimes too high, sometimes too low, but rarely in the right place.

The sawmill that knows its real cost has negotiating power. It can give a conscious discount to close a large client, can refuse an order that doesn't cover costs, can identify dimensions that drain margin and adjust the mix. Cost knowledge is decision power.
