Name Numerology Calculator

Numerology assigns a number to every letter of the alphabet. Enter a full name to see the three classic name numbers and exactly how each one is worked out.

For entertainment and self-reflection: Name numerology is a symbolic tradition with no scientific basis. The descriptions are traditional keywords, not an assessment of anyone’s character. Nothing on this page is a prediction, and it is not financial, medical, psychological or legal advice. Use it as a prompt for thought, not as a basis for decisions.

How name numerology works

Modern Western ("Pythagorean") numerology gives each letter a value from 1 to 9 by writing the alphabet out in rows of nine:

From a full name it then derives three numbers:

• Expression number (also called the destiny number): every letter in the name. It is said to describe your natural talents and the way you tend to go about things.
• Soul urge number (heart’s desire): the vowels only. It is said to describe inner motivation, what you want rather than what you show.
• Personality number: the consonants only. It is said to describe the side of you that other people see first.

For each number, this calculator adds the letters in each part of the name (first, middle and last), reduces each part to a single digit or a master number, then adds the parts and reduces again. Reducing means adding the digits together until one digit is left, except that 11, 22 and 33, the "master numbers", are kept and shown as, for example, 11/2. Reducing part by part is the most widely taught method. Some books add every letter at once instead, and that can occasionally give a different master number, so do not be surprised if another site disagrees.

The letter Y is a known grey area. Many numerologists count Y as a vowel when it sounds like one (as in "Lynn" or "Mary") and as a consonant when it does not (as in "Yolanda"). By default the calculator treats Y as a consonant; tick the box to count it as a vowel. Accented letters are converted to their plain form, so É counts as E.

For comparison the calculator also shows the Chaldean name number. The Chaldean system uses only the numbers 1 to 8 with a different, irregular letter table, adds the whole name at once and looks at the two-digit "compound" total before reducing it. Despite the name, there is no evidence that it comes from ancient Babylon; it was popularised in the early twentieth century by the palmist and writer known as Cheiro.

Worked example: John Smith

Expression. JOHN is J 1 + O 6 + H 8 + N 5 = 20, which reduces to 2. SMITH is S 1 + M 4 + I 9 + T 2 + H 8 = 24, which reduces to 6. Then 2 + 6 = 8.

Soul urge. The vowels are O (6) in John and I (9) in Smith. 6 + 9 = 15, which reduces to 6.

Personality. The consonants of JOHN are J 1 + H 8 + N 5 = 14, reduced to 5. The consonants of SMITH are S 1 + M 4 + T 2 + H 8 = 15, reduced to 6. 5 + 6 = 11, a master number, shown as 11/2.

Chaldean. With the Chaldean table, JOHN SMITH totals 35 and reduces to 8.

So, in numerology language, "John Smith" is an 8 expression (ambitious and capable) with a 6 heart (caring and responsible) and an 11 outer personality (intuitive, inspiring). The calculator shows all of this working for any name you enter, so you can check it yourself.

Where name numerology comes from

Linking letters and numbers is ancient. In Hebrew, Greek and Arabic, letters were also used as numerals, and the practice of finding meaning in the number values of words, called gematria in the Jewish tradition and isopsephy in Greek, goes back more than two thousand years. The Pythagoreans of ancient Greece taught that number underlies the order of the world, which is why modern numerology borrows their name, although nothing like the modern letter table appears in ancient sources.

The system used on this page is modern. It took shape in the United States in the early twentieth century, notably in the writing of L. Dow Balliett, and was developed by later writers including Juno Jordan, who founded the California Institute of Numerical Research and spent decades testing and teaching the name numbers. The idea of choosing or changing a name for its numerology also became popular in this period, and it is still common today in some countries, where people consult a numerologist about a baby’s name or a business name.

There is no scientific evidence that the numbers in a name affect personality or fortune. Psychologists have long noted, however, that general descriptions feel personal to most readers (the "Barnum effect"), which helps explain why numerology readings can feel accurate.

Using name numbers for reflection

Names carry a lot of meaning even without numbers: family history, culture, and the way we introduce ourselves. Some ways to use this calculator thoughtfully:

• Compare names you use. Your birth name, your everyday name and a nickname often give different numbers. Numerologists read the birth name as your core and the name you use as how you meet the world. It can be fun to compare them.
• Start a conversation. Whether the soul urge keywords fit can be a surprisingly good prompt for talking with a partner or friend about what you each value.
• Brainstorm names for fun. People sometimes use numerology when naming a pet, a project or a small business. Treat it as a tie-breaker for fun, after you have checked that the name is clear, available and easy to spell.
• Do not judge people by it. Keywords like "ambitious" or "private" are not a character assessment, and nobody should be hired, matched or ruled out because of a number.
