How Much Native American Am I? | Blood Quantum Calculator & Chart

Just got your DNA test and want to know more?

Or maybe you want to validate the family stories about your heritage?

If so, you may ask, “How much Native American do I have in my blood?” It is no surprise that many of us have a mixture of ethnicities in our blood. One of those dominates comes directly from our parents but if we consider our grandparents or our great-grandparents then the story changes a little.

A very frequently asked question is the percentage or fraction of Native American a person is and there are many ways to depict that but first, we must clear out some things so that the calculations are clearer, easier, and more accurate. The real question is what percentage of a particular ethnicity you have on paper in comparison to what you have genetically. Keep in mind that having Native American ancestry in your DNA does not make you part of a tribe. Being a certain percentage Native American is more than just blood; it's about being a part of a tribe, community, and culture.

If you look at the oral history of the family that tends to be a little inaccurate as it becomes either diluted or condensed as the time passes. 

An example of this can be seen in that if someone's grandmother claims that she is 3/4th, she might not be that because maybe she has more ethnicities that came from her grandparents further. Plus how does one have exactly 2/3rd of ethnicity because each person has four grandparents? So yes there can be some sort of ambiguity so the story that you hear might not be the whole truth.

It takes two people in each generation so the fraction can only be divisible of 2 or 4 but not 3. So in the case of grandparents it ¼ and in the case of great-grandparents, it's 1/8. This is the mathematical form to add some sort of clarity.

It is not as hard as it sounds just because it has math in it.

Let’s take a look at it.

How To Calculate Blood Quantum

First and foremost we must know that the DNA of a person is diluted in half so for that reason each ancestral generation is reduced to half because it makes more sense this way. So if for instance, a person's mother has 1/8 of a particular ethnicity then the person they would have a fraction of 1/16 because they inherited half of their mother's DNA. So by this, you can calculate. After that, you find the common denominator. I know this is a lot of math but we are dealing with genetics here so this is necessary.

So if you have, let's say the numbers 1/16 and 2/16 then they are easy to add because they have the same denominator. However, if you have two numbers with different denominators like 2/16 and 3/32 then you will make their denominators the same to add them. So you multiply 2/16 with two and you get 4/32. Now you can add both these fractions. Now once you are done with this, you move on to adding the numerators or the top numbers together.

Once you have added those you have the fraction of the Native American Ethnicity that you have in you on paper and you can now convert that into percentage form and know exactly. For this, you must know fractions in your family tree to make sure those are accurate.

So in simpler words, we get the equation:

Mothers blood degree + Fathers blood degree = Total blood degree/Total divided by half = Childs blood degree

All this mathematical game was too easy to be true.

But now you have to figure out how to prove this particular information. This is where genetics step in. If we talk about Native ancestry then the answer varies on the purpose i.e. general interest, tribal identification or tribal membership, etc. For this, you can, of course, take a DNA test from Family Tree DNA called Family Finder which will further provide you with the percentage of ethnicity you have including Native American with the addition of the list of cousin matches. You are also offered additional tests in the case of relevance to figure out if you descend from the Native person paternally (male) or matrilineally (for both the sexes). Information that will be useful is that the Y DNA is inherited by males from their fathers and the mitochondrial DNA is always inherited by their mothers. These particular tests of the mitochondrial and Y give you very specific information.

On the other hand, Family Finder provides you with the information of your ethnicity judging by all your lines giving you more in-depth and accurate information. The only thing it cannot tell you is from which lines or lines the Native American heritage came. The information is such that a person can be considered a full Native tribal member although the person might have just half Native American Heritage. So what do we learn from this?

It is that you should always enjoy and cherish your family history and heritage. Another thing that you must keep in mind is that tribal memberships were not based on percentages in history at least not until the 1800s and early 1900s. You must also know that your ancestor was either an Indian tribal member or was not one and this is based on the tribal status of their mothers. In history, there was no concept of halfway or mixed so percentages and fractions did not matter.

By DNA testing, the percentages will also help you figure out where you got the Native American heritage from. The calculations are translated as: For instance, if you are 50% / Half Blooded Quantum meaning One Parent If you are 25% / One-Fourth Blood Quantum meaning One Grandparent 12.5% is One-Eighth Blood Quantum meaning One Great-Grandparent 6.25% is One-Sixteenth Blood Quantum meaning One Great-Great-Grandparent And so on, showing that this is how the percentage helps pinpoint where you got your Native American heritage from.

If you want to confirm Native American heritage then a DNA test is the best way. It can also do so in a variety of ways such as how is the heritage descended on you with the tests of Y and mitochondrial DNA. Depending on whether the person is a male or a female and how the person descends from his or her Native ancestors. If the person gets the Y or the mitochondrial DNA test done then there could be an abundant amount of information added in the person’s family history. In the case of some people, DNA testing is used to deduct and discover if they have a Native ancestor. So if accurate information without any ambiguity is what you are looking for then the best way to find out is through DNA testing and also finding out the percentage you have on paper.

    My maternal great-grandmother told me stories about our Family as Choctaw. Her father my great great grandfather is registered as full blooded Mississippi Choctaw. I was also able to trace the tribal names in Mississippi. I have the identification for Mississippi Choctaw information from 1901 not sure if they’re still valid. And did a genealogy test with me having indigenous American DNA. Where can I go to access the records of tribal members of the 1800-1900s?

    This is truly sad. I was adopted at birth and have only found out of my Native American heritage through DNA, there was some speculation of course, I have black hair and dark brown eyes and olive skin and my family are all western European (blonde, blue eyes, fair skin). I have since found my biological mother however she was ALSO adopted. We were both raised in the Four Corners area and we have lots of DNA relatives but how are we supposed to find where WE fit in this world, the privilege of having those stories told to us was stripped. We didn’t get a say in that. We both have a strong connection to the tribes in our area and with the culture but that does not get us tribal rights because we DON’T belong.

    Apologies for trying to understand this discussion. I do not mean to be offensive. But I must say that theories that separates human groups by ‘blood quantam’ has been, historically, and currently, a tool of racist oppression. I am from Virginia: Virginia eugenics laws (Racial Integrity Act and Eugenical Sterilization Act both in the same year) were used oppress groups in horrible ways because of ‘blood quantam’, with ‘purity’ of north european ‘blood’ to be being the highest in the hierarchy. The ‘one drop’ rule – one drop of non-north european ‘blood’ pushed you down the hierarchy. Of course these eugenical theories were/are horribly un-scientific, un-ethical, and un-just. And the horrible results of such theories and laws is well known. So, shouldn’t the discussion of heritage, and pride in heritage, be undertaken in some other terms than racist-eugenical ‘blood quantam’? Thank you.

My Grand mother and grand father nor my father and mother had no recorded Native American blood, what % of Cherokee blood would that make me ? Thanks

    My mother was a purebred Choctaw and through Ancestry I am finding many relatives in Mississippi who are recorded as “Mulatto”. They had a close relationship as a mixed African Americans with the Creek and Choctaw.

    I want to know can Mulatto be half Indian too because there are not any Caucasian in our family in the 1700-1900’s?

    Hello! It is my understanding that 23&Me & use some government documents for your estimate. It is only an estimate. The percentages, I’m told, don’t work like a pie chart. For example if it says 50% Italian & 2% Chinese, …, it doesn’t mean you are half Italian. It means you have a higher chance of having ancestors from Italy than from China based on their estimate & these estimates change over time. Also, they do not have all the samples, so they may not have a sample group for your ancestors. As for the government documents, they may be inaccurate. Some of your native ancestors who lived off the reservation may be documented on the census as “white” sometimes, at other times “black”, yet other times “mulatto” based on the census takers knowledge & experience. … I was told again that your best bet is to go by what your elders have said. They are more trustworthy than someone who stands to make money off of you. As for native heritage & nations, if someone on the nation recognizes your family as being part of their nation, then you descend from there. However, the connection may have been lost & things not documented. It doesn’t mean you can’t learn about that part of your heritage, just that you can’t be member of a tribe. Blood quantum shouldn’t matter for you the way it does with the tribes. …

          There is no DNA test you can do to provide proof and no DNA test is usable to enroll in the tribe. If you can prove you are a direct decsendant from am enrolled member on the final roll cards no matter what the blood quantum is you can enroll

        No, if you are 1/16, you kids would be 1/32, which isn’t enough DNA to be considered for membership. It takes a minimum of 1/16th to be considered a member.

      • Avatar for MarkAnthony Ramsey

        Yes as long as you can provide direct lineage to a member on the final roll card you are eligible for membership no matter what the blood quantum is there is no minimum qualifications for Cherokee Nation. This does not count Eastern Band they require 1/4 any one tells you different they don’t know what they are talking about

    • Avatar for Tony Howell

      This article oversimplifies the DNA aspect. We inherit 1/2 of our DNA from our father and 1/2 of of our DNA from our mother. However, we don’t inherit exactly 1/4 of the DNA from each of our grandparents due to the randomness of what DNA is passed to us from our parents. So, we could actually have more or less DNA from a particular grandparent. On average, we could possibly get 25% of our DNA from each of our grandparents, but our actual DNA ethnicity percentages will usually not match exactly what we show “on paper.” If siblings take the same DNA test, each of their ethnicities can vary.

    • Avatar for Tricia



      It’s nice you can say you’re recognized as full blood but I disagree that just because one is not full traditions are lost. I’m nowhere near full and I know my history and where I came from on my moms side and so do my cousins and friends that have gone on to have mixed children as well. It’s too bad tribes took away the right to be enrolled after you drop below a quarter because I look and know more then some that are considered more then me.

    My grandfather was 100%. So I would be 1/4 at least,( my mother has some not sure how much.) I can go on the registry. My youngest brother is already on it and he is part Italian because of his mom. I consider myself native. I just don’t hold very much of anything else and don’t look the part at all. Native genes are dominate I guess? But should I? Or having 1 grandfather 100% pointless? I’m not sure how much my father is I just know he was what they said like 80%. Is it worth the research to find out how much I am?

    • Avatar for Tricia



      If you can prove your grandfather is or was considered a full blood Native American in that tribe that would make you a quarter of your mother or father were mixed with something else. To prove it like I did to use the IHS hospital other then where my mom was enrolled I had to show her enrollment papers and match it to my birth certificate. My grandfather was considered half because only one parent was considered full blood and he married outside making my mom a quarter which makes me able to prove myself as a descendant that way. My mom had brought me and my brothers off and on to the IHS where she is from so I was always able to go there whenever I wanted with no questions ask but I moved further away from that reservation and wanted to use White Earth in Minnesota’s hospital which is another Chippewa reservation. I was told as long as I could prove I was a descendent I would be ok. Look into it and if you can find documentation and have your birth certificate to prove who your parents are against the enrolled member you can take it from there. I had my mothers original paper and ID put away after she passed and already knew where I stood before her passing. I look more native to some then French, German or black accept I stick out more I think when I let my big curls down, but the way I look at it, it’s not my fault I’m not considered more.
      Good Luck!

    My grandfather is 100%, I have no idea the percentage my grandmother was. My father would be 1/2 at least so I would be 1/4? My mother has native blood aswell so I’m not too sure how much.

    By census I am roughly 3% Croatan and Pee, by blood I’m less than 1%. Was raised Croatan, was told I was Native American all my life. DNA tests and blood percentage are just another way I feel that people are trying to extinguish our culture and people. They say we’re white people playing Indian, not upholding sacred teachings and ways of life of a people destroyed by disease, war and over 100 years of racism. I wish we could do away with these concepts and live how our grandfathers and grandmothers believed.

    My grandmother (maternal) was born on the Indian Territories before it became Oklahoma. the 1910 US Census state that she and my Great Grandmother were “Indian” The family “tradition is that my Great Grandmother was found by settlers on the Trail from Missouri to thre territories and was brought into the family , and that she was considered “Black Dutch”. My Grandmother stated to me that her mother was from the Kiowa-Apache tribe near the Stockade of Ft. Sill. No birth records from the pre statehood days is making it hard for me to trace true lineage. the K-A were not listed as a tribe on the Dawes Rolls, so i am at a quandry.

    I do not claim any Native heritage. I am Welsh on my fathers side and English on my mothers side by birth, and yet since childhood I have identified with the Navajo people, I love to read about the country and have three Navajo pen pals.

      I have nothing in the blood. It only shows DNA markers to link me to a 4th great grandmother and her parents. They were Creek. But as the blood quantum calculator proves, this is how that blood is watered down. So I’m completely white. I am not allowed to claim them, and any no one in the Creek or Seminole tribes will bother with me. According to the DNA, the 5th great grandfather was someone well known. But again, I am not allowed to claim him, as too many white people do that. Even though I have DNA links to his other living descendants, and a direct line from his daughter. I may as well have never found out.
