Texas royalty estimator

Estimate a monthly royalty check from lease production. Every input is shown and editable. This is a gross estimate before severance taxes and any post-production deductions your lease allows, so your actual check will usually be lower.

Oil + condensate produced in the month (BBL) Oil price ($/BBL)

Default: WTI Cushing spot, monthly average, September 2026: $97.31 (U.S. EIA). Your purchaser's price will differ; use the price on your check stub if you have it.

Gas produced in the month (MCF) Gas price ($/MCF)

Default: Henry Hub spot, monthly average, September 2026: $2.95 per million Btu (U.S. EIA). EIA quotes $/MMBtu, not $/MCF; gas heat content varies, so edit this if your stub shows a different price.

Your decimal interest (from your check stub or division order)

Don't know it? Estimate it below as royalty rate × (your net mineral acres ÷ unit acres).

How the estimate works

Royalty ≈ (oil volume × oil price + gas volume × gas price) × your decimal interest. Your decimal interest is normally your lease royalty rate multiplied by your share of the pooled unit (net mineral acres ÷ unit acres); the operator states it on your division order.

Production volumes for any lease are on its Extrxct page and in the RRC Production Data Query. Not tax or legal advice.
