The African Ancestral Calculator (by Batetela) is a free Global25 ancestry calculator (Calculateur, G25, Scaled). The African Ancestral Calculator is a free Global25 (G25) ancestry calculator by Batetela that breaks your DNA down into the deep ancestral layers of Africa and of the out-of-Africa world. African sources include ancient hunter-gatherers from South Africa (Oakhurst, Ballito Bay), Central African rainforest hunter-gatherers (Mbuti-like and Biaka-like), West African farmers (Esan-like, Nigeria), a Mota-like East African forager from Ethiopia, Dinka-like East African pastoralists and Ancestral North Africans from the Green Sahara (Takarkori, Libya). Out-of-Africa references range from Upper Paleolithic Eurasians (Ust-Ishim, Kostenki, Zlaty kun, Tianyuan, Villabruna) and Anatolian farmers to modern Papuans, Onge, Aboriginal Australians, Han Chinese, Karitiana, Georgians, Yemenite Jews, Finns and English. It is made for African and African diaspora profiles, and for anyone curious about how deep African ancestry is shared out. Paste your scaled G25 coordinates to get your best-fit mix, computed directly in your browser. Its reference panel holds about 44 reference populations, grouped mainly as South AfricanHG/North, OOAII, South AfricanHG/South, West African Farmer/Esan-like, Ancestral North African/Para-Eurasian, East AfricanHG/Mota-like, East AfricanPastoral/Dinka-like, CAHG East/Mbuti-like.The panel was built or amended by Batetela.Last updated: November 2026.
People who already have their Global25 (G25) coordinates, for example from a raw DNA file converted with our G25 coordinates service, and want to see how a specific reference panel reads them. Different calculators use different panels, so the same person can get different percentages, and comparing several is more informative than trusting one.
Paste your coordinates, choose a run mode and start the calculation. Each result line is a reference population followed by the share of your ancestry it explains, the shares add up to 100%. Very small shares (below roughly 1 to 2%) are usually noise rather than real ancestry. The distance value tells you how well the mixture reproduces your coordinates: the lower, the better, and a high distance means this panel does not describe you well. For example, a result of "Polish 60 / Ukrainian 25 / Lithuanian 15" means your coordinates are best rebuilt from those three populations in those proportions, not that you descend from three separate groups.
