FTDNATiP™ (FamilyTreeDNA’s Time Predictor) is a program that predicts the time to the most recent common ancestor for two men based on their Y-chromosome STR matching and STR mutation rates. FTDNATiP™ provides powerful and precise calculations of Time to the Most Recent Common Ancestor (TMRCA) by incorporating mutation rates specific to each STR marker.

It is important to understand if the TiP calculator says you have, for example, an 80% chance to share a common paternal ancestor with someone else within 8 generations, this does not mean your common paternal ancestor existed 8 generations ago. It means there is an 80% chance your common paternal ancestor existed sometime between now and 8 generations ago.

To use FTDNATiP™:

  1. Sign in to your myFTDNA account.
  2. On your dashboard, select Matches in the Y-DNA section.
  3. On Y-DNA – Matches, click on the orange TiP icon next to a match’s name to run the FTDNATiP™ report for that match.
