Chaldean numerology is the system most practitioners use for business names, because it assigns letter values by sound rather than by alphabetical position. This calculator gives you the compound number, the single digit and the ruling planet of any business name.
Chaldean Numerology Calculator for Business Name
Check your business name's Chaldean compound number, single digit, and ruling planet instantly. This free calculator uses the ancient Chaldean alphabet-to-number system — the method professional numerologists prefer over Pythagorean for business name analysis.
How this calculation works
Chaldean numerology assigns each letter a value from 1 to 8. The number 9 is never assigned to a letter — it is treated as sacred and appears only as a total. The values follow the sound and vibration of each letter, which is why they do not run in alphabetical order:
| Value | Letters |
|---|---|
| 1 | A, I, J, Q, Y |
| 2 | B, K, R |
| 3 | C, G, L, S |
| 4 | D, M, T |
| 5 | E, H, N, X |
| 6 | U, V, W |
| 7 | O, Z |
| 8 | F, P |
The calculator adds the values of every letter, giving the compound number. It then reduces that total to a single digit, except when the total is 11, 22 or 33 — the master numbers, which are kept intact.
Legal suffixes are stripped before calculating. Pvt Ltd, LLP, Inc, and Co are registration formalities, not part of the name customers use, so they are excluded.
How to read your result
Two numbers come out, and they answer different questions.
The single digit names the ruling planet and tells you the broad character of the business — how it sells, who it attracts, what it is naturally good at.
The compound number is the finer reading. Two names can both reduce to 5 while one sits on 23, a compound traditionally regarded as one of the most fortunate in business, and the other sits on 32, which behaves quite differently. The compound is where the specific advice lives.
Compounds fall into three groups: favourable (19, 21, 23, 24, 25, 27, 37, 41, 51), warning (13, 16, 18, 26, 29), and neutral — everything else. The full 10 to 99 table gives the meaning of each.
What to do if the result is poor
A warning compound is not a verdict that the business will fail. It describes a pattern of recurring obstacles in a specific area — 26 tends to show up as partnership and financial trouble, 16 as sudden reversals after periods of success.
If your name lands on one, work through this order:
- Run the name correction calculator to find spellings that keep the brand recognisable while shifting the compound.
- If a legal change is impractical, change the display spelling on signage, website and marketing — the name as written and used daily is what numerology reads.
- Strengthen the supporting layers: planet-aligned colours, launch timing, and the business phone number.
What this calculator does not tell you
This calculator reads the business name alone. It does not know your date of birth, so it cannot tell you whether the name suits you — the most common source of a name that looks strong but never settles. For that, use the date-of-birth calculator.
It also reads one spelling at a time. If you are choosing between candidates, run each separately and compare the compounds.

Frequently Asked Questions
Why does Chaldean numerology have no letter with the value 9?
In the Chaldean system 9 is treated as sacred and is never assigned to a letter. It still appears as a total — a name can reduce to 9 — but no single letter carries it.
Should I include Pvt Ltd in the calculation?
No. Legal suffixes are registration formalities rather than part of the name in daily use. The calculator strips Pvt Ltd, LLP, Inc, Co and similar automatically.
Which is more accurate for business names, Chaldean or Pythagorean?
Most practitioners use Chaldean for business names because it works from sound rather than alphabetical order, and business names are spoken far more often than they are read letter by letter. Pythagorean remains useful for reading how a name presents itself publicly.
What if my name reduces to a master number?
Master numbers 11, 22 and 33 are not reduced further. They carry an amplified version of their base energy — 2, 4 and 6 respectively. Read the master numbers page for what each means in business.
