Timber Yield Calculator

Work out timber yield instantly with clear inputs, formula shown and shareable results.

About Timber Yield Calculator

Scales stem volume per tree to the whole stand and applies the mill recovery rate to give sawn timber output.

Formula

Timber yield

Standing volume = volume per tree x trees per hectare x hectares; sawn timber = standing volume x recovery rate

Worked example

With the default values below, Timber Yield Calculator returns Sawn timber recovered of 1,440.00. Change any input above and every figure here is recalculated in your browser.

Inputs used

Stem volume per treeaccepts 0.01–50 m3: 1.2 m3
Trees per hectareaccepts 1–5,000: 400
Areaaccepts 0.01–100,000 ha: 5 ha
Sawn timber recoveryaccepts 20–90: 60

Results

Sawn timber recovered: 1,440.00 m3
Standing stem volume: 2,400.00 m3
Standing volume per hectare: 480.00 m3/ha
Residue and offcuts: 960.00 m3

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

What recovery is typical?

45 to 65% for sawlogs depending on log size, taper and sawing pattern; the rest becomes chips and sawdust.

Does small log size reduce recovery?

Yes, markedly. Slabbing losses are proportionally larger on small-diameter logs.
