One calculated name number opens up several interpretive themes. These five perspectives are not five separate numbers.

How the numbers are calculated
A name calculated in parts, not a Pythagorean sum
This calculator follows the approach popularized by Cheiro. Letters take values from 1 through 8; none is assigned 9. Each part of the name you commonly use is calculated separately and reduced to a single digit. Those roots are then added to produce the name key.
Compound numbers remain visible because they add a second layer of traditional interpretation. Your birth day is considered separately, including its two-digit compound when applicable.
How the calculator works
How Chaldean numerology calculates your name
Chaldean numerology uses a letter chart traditionally associated with the system popularized by Cheiro. Letters are assigned values from 1 through 8, with no letter given the value 9. A calculation can still reduce to 9; the difference lies in the letter assignments, not in the range of possible results.
NumberAIO calculates the name you commonly use one part at a time. It totals the letters in each part, reduces those totals to single digits, and then combines the roots to obtain the name key. Your day of birth is calculated separately. Both the root and an eligible two-digit compound remain visible, because two different compounds can share the same final digit.
The name people know you by
Use your commonly used first and last name, rather than automatically substituting your complete birth name. The breakdown shows every word and its individual letter values.
Compound and root
The compound preserves a traditional layer of meaning before the final reduction. A result of 23/5 therefore differs in its origin from 14/5, even though both have root 5.
The birth-day number
Only the day of the month is used for this separate value. Someone born on the 29th keeps compound 29 and reduces 2 + 9 = 11, then 1 + 1 = 2.
Worked example
A worked example with CHEIRO
You can check the Chaldean letter chart with the six letters in CHEIRO. This demonstrates a single-name calculation; a multi-part name is calculated word by word before its reduced values are combined.
- C = 3 · H = 5 · E = 5 · I = 1 · R = 2 · O = 7.
- 3 + 5 + 5 + 1 + 2 + 7 = 23.
- Compound number: 23, traditionally called the Royal Star of the Lion.
- 2 + 3 = 5. The root number is 5.

Letter values used by this calculator
These values differ from the Pythagorean alphabet. The same name may produce different totals in the two methods, even when every letter is entered correctly.

Frequently asked questions
Questions about Chaldean name numerology
Why is no letter assigned the number 9?
In the Chaldean table associated with Cheiro, letters receive values from 1 through 8. Nine can still appear as a root: for example, the total 18 reduces to 1 + 8 = 9.
What is a compound number?
A compound is a number kept before the final reduction to one digit. Compounds such as 14 and 23 both reduce to 5, but the traditional interpretations associated with them are different.
Should I enter my birth name or the name I use now?
This calculator follows the commonly used name approach associated with Cheiro. Enter the name people generally use for you. You can explore another spelling if it is genuinely part of how you are known.
How is this different from Pythagorean numerology?
The Chaldean letter assignments do not include 9 and give special attention to compound numbers. NumberAIO’s Pythagorean tool uses your birth name and date to build a more extensive chart with cycles and other positions.
Are the readings predictions?
No. The numbers and compound associations are part of a symbolic tradition, not a scientifically validated assessment of personality or a forecast of events. They can be used as prompts for reflection.
