Check my decimal against the unit

Estimator

Estimate your royalty for this lease

A rough check before you look at a statement: the state volumes times your decimal, priced at WTI and Henry Hub.

Estimator

What could your check be?

Your decimal interest is the small number on your division order that says what share of the whole lease (8/8ths) is yours. Type it in and we apply it to what the state says KEY, E. sold each month.

For example 0.00097656, or a fraction like 1/1024.

Dollars per barrel. Your statements show the gap your operator uses. Leave 0 to price oil at WTI.

Your estimate appears here

Enter your decimal to see an estimated royalty for each of the last 12 months this lease reported. Nothing you type leaves your browser.

An estimate, not your check

It ignores gathering and processing fees, taxes, plant products and the price your operator actually gets, so your statement will differ. Use it as a ceiling to compare against.

How to read this page

Questions owners ask

What is a decimal interest?

It is your share of the whole lease, written as a decimal. A 1/4 royalty on 5 net acres in a 1,280-acre unit is 1/4 × 5 ÷ 1,280 = 0.00097656. Your division order states yours.

How do I use this page to check a royalty check?

Take the “Oil sold” volume for the month the check covers and multiply it by your decimal. The answer should match the barrels on your statement. If it does not, upload the statement and we will show where the two differ.

Why is the newest month Jun 2026?

The Railroad Commission publishes production two to three months after the fact and revises recent months. We re-pull the latest three months on every update.

Does this page show what my check should be?

No. It shows what the state recorded. Prices, fees and taxes depend on your lease and on what your operator gets for the oil and gas. The estimator gives a ceiling to compare against.
