Refinery Yield Calculator

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

About Refinery Yield Calculator

Refinery yield is the volumetric split of crude into products. Light product yield — gasoline plus diesel and jet — is the key value driver, since those streams carry the highest margins. Volumetric yields often sum above 100% because cracking and reforming reduce average density, an effect known as processing gain.

Formula

Refinery yield

Product volume = crude charged x product yield %; light product yield = gasoline % + diesel and jet %

Worked example

With the default values below, Refinery Yield Calculator returns Light Product Yield of 77.00%. Change any input above and every figure here is recalculated in your browser.

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 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

Why can yields exceed 100%?

Conversion units break heavy molecules into lighter, less dense ones, so total product volume exceeds crude volume even though mass is conserved. Processing gain is typically 2-6%.

What sets the achievable yield?

Crude quality and refinery configuration. A simple hydroskimming refinery on heavy crude yields mostly fuel oil; a complex coking and hydrocracking refinery converts nearly everything to light products.
