LB-EIA World Calculator (by C.S. ) is a free Global25 ancestry calculator (Calculateur, G25, Scaled). Usage tips: removing sources that don't apply to you Not British? Remove PreRoman_Britain. Italian? Remove Bulgaria_EIA, Macedonia_IA and the other Thracian coordinates. Albanian? Rename Thracian to Illyrian. Western or Southern European with some Western Iranic input? Remove Western Iranic. Italian with heavy Celtic or Germanic input? Remove one or the other. Slavic with some Thracian input? That is expected, keep it. Not Iberian? Remove Iberian. Its reference panel holds about 204 reference populations.The panel was built or amended by C.S..Last updated: October 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.
