Oil Royalty Calculator

Use the oil royalty calculator below to calculate your decimal interest and then to estimate your monthly revenue. It’s simple and it’s free. Remember, oil prices and production rates continually change, so feel free to come back regularly to freshen your revenue estimate.

Also, use MineralWeb’s  Natural Gas Royalty Calculator if your well produces natural gas.  Combine the results from both calculators if you have a well that produces both oil and gas.
