Crop Yield Calculator

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

About Crop Yield Calculator

Scales a sample plot harvest to a hectare and adjusts for grain moisture above the standard trading level.

Formula

Crop yield

Yield per hectare = plot yield / plot area x 10,000; moisture-adjusted yield = yield x (1 - excess moisture fraction)

Worked example

With the default values below, Crop Yield Calculator returns Yield of 4.5000. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 3 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 4 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 is standard moisture?

Commonly 14% for wheat and maize and 13% for soybean, though trading standards vary by market.

How many sample plots are needed?

At least three to five well-separated plots, since within-field variation is often 20% or more.
