How Do You Calculate Mineral Interest Using Royalty Calculator?

It is quite common that mineral and royalty owners don’t know exactly how much interest they own and yet it’s one of the most important things they need to be aware of as a responsible interest owner.

Some of the most common terms used to describe the amount of mineral and royalty interest include: Net Royalty Acre (NRA), Net Mineral Acre (NMA), and Division of Interest (DOI), which is commonly referred to as Net Revenue Interest (NRI).

Knowing your NRA, NMA, and DOI information is important for several reasons including:

  • Provides a clear understanding of the owner’s financial interest as it relates to their mineral and royalty interests.
  • Facilitates decision-making regarding the management of their mineral assets (i.e. revenue potential, negotiations for the lease, or sales of their interests).
  • Provides transparency in the calculation of payments and helps to avoid disputes with the Lessee or Operator, and/or other mineral and royalty owners.
  • Clarifies the ownership and revenue sharing arrangement between multiple parties that have mineral and royalty interests in a tract of land and/or producing unit.
  • Represents the actual amount of revenue from a producing well the owner will receive after the Operator deducts various taxes and expenses, and after accounting for any leased or sold mineral rights.

What Is A Mineral Acre?

Referred to as a Net Mineral Acre, or NMA, it is a representation of the net acreage owned by a mineral owner from under the gross acres of a particular parcel or tract of land. 

For example: If the gross acres of a tract of land are 40 gross acres and you are stated to own half of the minerals in that particular tract of land, then your net mineral acres owned are equal to 20 net mineral acres.

What Is A Royalty Acre?

A Net Royalty Acre, or NRA, is similar but different to that of a Net Mineral Acre. A Net Royalty Acre is a net mineral acre that is subject to an oil, gas, and mineral lease with a certain royalty percentage granted and provided for within that lease. It becomes a NRA once a mineral interest has been leased, otherwise it remains a net mineral acre (NMA). 

Net royalty acre is the most common term used today for mineral buyers so it is very important to know the difference between Net Mineral Acres and Net Royalty Acres.
