In numerology, every letter of the alphabet corresponds to a number. This is how your name is translated into a vibration how “Rahul” becomes a 5, how “Priya” becomes a 1, how any business or brand name becomes a single-digit energy that influences its trajectory. Two major systems assign these values differently, and this chart lays out both side by side.
The Two Major Systems
Chaldean (also called Vedic numerology in Indian practice) is the older system, originating in ancient Mesopotamia over 4,000 years ago. It assigns letters to numbers 1 through 8 only the number 9 is considered sacred and unassigned. This is the system used in most Indian name numerology consultations.
Pythagorean was developed by the Greek mathematician Pythagoras around 500 BCE. It is sequential A=1, B=2, C=3 and uses all nine numbers. This system is more commonly used in Western numerology.

How to Calculate a Name Using This Chart
Take each letter of the name, look up its value in the Chaldean column (or Pythagorean if you prefer that system), add all values together, and reduce to a single digit.
Example: Rahul (Chaldean)
R = 2, A = 1, H = 5, U = 6, L = 3. Sum = 2+1+5+6+3 = 17. Reduce: 1+7 = 8. Rahul’s name number in Chaldean numerology is 8 ruled by Saturn, the Executive archetype.
Example: Priya (Chaldean)
P = 8, R = 2, I = 1, Y = 1, A = 1. Sum = 8+2+1+1+1 = 13. Reduce: 1+3 = 4. Priya’s name number is 4 ruled by Rahu, the Builder archetype.
Example: Amazon (Chaldean)
A = 1, M = 4, A = 1, Z = 7, O = 7, N = 5. Sum = 25. Reduce: 2+5 = 7. Amazon’s brand vibration is 7 Ketu’s number, associated with mystery, research, and unconventional success. An interesting choice for a company that started as an online bookstore.
Why Chaldean and Pythagorean Give Different Results
The two systems can produce completely different name numbers for the same name. Taking “Rahul”: Chaldean gives 8, but Pythagorean gives R(9) + A(1) + H(8) + U(3) + L(3) = 24 → 6. The same name, depending on system, is either a Saturn energy or a Venus energy.
This is why it matters which system you use. For Indian contexts matching birth chart, choosing children’s names, business naming stick with Chaldean. For Western personal development contexts, Pythagorean is more common. Mixing them produces nothing reliable.
Special Rules in the Chaldean System
Three things to know when calculating Chaldean name numbers:
- No letter equals 9 in the Chaldean system. 9 is considered sacred and unassigned.
- Use the name you are called by. The most frequently-used form of the name carries the strongest vibration so if you go by “Priya” but your passport says “Priyadarshini,” calculate “Priya” for daily vibration.
- Include spellings exactly including double letters. “Anna” is A(1)+N(5)+N(5)+A(1) = 12 → 3. “Ana” is A(1)+N(5)+A(1) = 7. Same pronunciation, different vibration.
Frequently Asked Questions
Which numerology alphabet chart should I use Chaldean or Pythagorean?
For Indian contexts (birth chart matching, baby names, business names in India), use Chaldean. It is the system that aligns with Vedic astrology. For Western personal-development uses, Pythagorean is the common choice. Pick one and stick with it mixing the two produces inconsistent results.
Why is there no letter with value 9 in the Chaldean chart?
In classical Chaldean tradition, 9 was considered the divine number and kept reserved for the sacred realm. No letters were assigned this value. You can still have a Chaldean name number of 9 it emerges only through summing and reducing, never from a single letter.
Should I use my full name or my nickname?
Use the name people call you by most often. Vibrational numerology is activated by usage, not by what appears on official documents. If everyone calls you “Raj” even though your birth certificate says “Rajesh Kumar Sharma,” then “Raj” is your active vibration.
Do I include my middle name and last name?
Traditionally yes calculate your full name for your complete Naamank. Then also calculate just your first name separately for your daily-use vibration. Both are valid; the full name shapes long-term life path, the daily name shapes day-to-day experience.
What if my name has non-English letters (é, ñ, é)?
Strip the accent and use the base letter. “José” becomes J-O-S-E. For names in Indian scripts (Devanagari, Tamil, Bengali etc.), use the transliterated English spelling that matches how you write your name in English.
