Your Name Numbers
Each letter mapped to its Pythagorean (P) and Chaldean (C) value.
The two most widely used name numerology systems each assign different values to letters, often producing different results for the same name. Seeing both together gives you a richer, more layered interpretation.
Developed in ancient Greece and popularised in Western numerology, Pythagorean assigns values 1–9 sequentially: A=1, B=2, C=3 … I=9, then J=1 again, and so on. It is the most widely used system today and is straightforward to apply.
The older of the two, rooted in ancient Babylonian tradition. Chaldean assigns values based on sound vibration rather than alphabetical sequence, and treats 9 as sacred — no letter is assigned the value 9. Many traditional numerologists consider Chaldean the more precise system.
Neither is definitively correct — they represent different traditions and interpretive frameworks. Pythagorean is more widely used in modern Western numerology. Chaldean is considered more precise by many traditional practitioners. Comparing both gives you a broader view of the energies carried by your name.
Most numerologists recommend using your full birth name as it appears on your birth certificate for the most significant reading. You can also calculate nicknames or married names to understand how those names influence your current energy.
Master numbers — 11, 22, and 33 — are not reduced to a single digit because they carry heightened spiritual significance. They represent elevated potential and intensified energy, though they also come with greater challenges and responsibilities.
In some numerology systems, Y is treated as a vowel when it functions as one phonetically. This calculator treats Y as a consonant for consistency, which is the most common approach in both Pythagorean and Chaldean practice.
