Gematria Calculator

Every letter has a number, and every word a total. This calculator computes the gematria value of any word or phrase in the Hebrew alphabet, in Greek isopsephy, and in three English systems, then reduces the total to the single number that carries its traditional meaning.

Updated August 23, 2026: standard Hebrew letter values, Greek isopsephy, and the three common English systems.

How Gematria Works

Gematria is the oldest letter-to-number system in the Western esoteric tradition. In the Hebrew alphabet every letter carries a value: Aleph is 1, Bet is 2, and so on up to Tav at 400. The value of a word is the sum of its letters, and the tradition reads words with equal values as connected. The classic example is the pair echad (one) and ahavah (love), both 13: the tradition reads the correspondence as a hint that unity and love are the same thing seen from two sides. The same practice, under the name isopsephy, runs through Greek: the values are the same idea in a different alphabet.

English gematria is younger but follows the same logic. The Ordinal system gives A=1 through Z=26. The Reduced system wraps the alphabet into 1 through 9 (A=1, I=9, J=1, R=9, S=1, Z=8), which connects English words to the same reduced numbers used in numerology. The English system follows the older 6-based tradition where A=6, B=12, C=18, and so on. The calculator shows all three, because the system changes the value but not the method: the total is still the sum, and the reduced reading is still the meaning.

How to Read the Result

Start with the exact value in the system you chose. In Hebrew and Greek, exact totals are compared between words: two words sharing a total are the correspondence to investigate. Then reduce the total by adding its digits (13 becomes 4, 400 becomes 4) until a single digit remains, keeping the master numbers 11, 22, and 33 as they are. The reduced number carries the traditional meaning printed under the result: it is the same vocabulary of numbers that numerology uses, which is how gematria and numerology meet.

The Hebrew and Greek readings in this calculator work from transliteration: you type the word in English letters, and the calculator maps them to the Hebrew or Greek letter with the closest sound (A to Aleph, B to Bet, Ch to Het, Sh to Shin, Th to Tav, and so on). For words that exist in the original languages, the transliteration is exact enough for the classical comparisons. For English words, the Hebrew value is a curiosity, and the English systems are the ones to use.

Frequently Asked Questions

What is gematria?

Gematria is the practice of assigning numerical values to letters and words, then reading the numbers that result. In the Hebrew tradition every letter has a value (Aleph is 1, Bet is 2, and so on), and words with the same total value are considered connected. The same idea appears in Greek isopsephy and in English letter-number systems.

How is Hebrew gematria calculated?

Standard Hebrew gematria uses the twenty-two letters of the Hebrew alphabet with their classical values: Aleph 1, Bet 2, Gimel 3, Dalet 4, He 5, Vav 6, Zayin 7, Het 8, Tet 9, Yod 10, Kaf 20, Lamed 30, Mem 40, Nun 50, Samekh 60, Ayin 70, Pe 80, Tsadi 90, Qof 100, Resh 200, Shin 300, Tav 400. The calculator transliterates the word you enter into Hebrew letters and sums their values.

What is the difference between gematria and numerology?

Numerology usually works from dates and names using the 1-9 Pythagorean chart. Gematria works from the spelling of any word or phrase in a sacred alphabet (Hebrew, Greek) and finds the total value, then often reduces it. The two traditions meet in the meaning of the reduced numbers, which is why this calculator gives both the exact value and its reduced reading.

What does it mean when two words have the same gematria value?

In the tradition, words sharing the same numerical value are considered to share a hidden relationship: the classic example is the Hebrew words for "one" (echad, 13) and "love" (ahavah, 13). The connection is read as a correspondence, not a proof, and it is one of the main uses of gematria in commentary.

Which English system should I use?

The calculator offers three: Ordinal (A=1 through Z=26), Reduced (A=1 through I=9, repeating), and English (A=6, B=12, and so on). The Ordinal system is the most common for English gematria; the Reduced system connects to the same 1-9 meanings used in numerology; the English system follows the older 6-based tradition.

Sources

The Hebrew values follow the standard twenty-two letter gematria (the Mispar hechrechi) as used in classical commentary. The Greek values follow the standard isopsephy table (Alpha 1 through Omega 800). The English systems follow the three conventions in common use: Ordinal (A1Z26), Reduced (the 1-9 cycle), and English (multiples of 6). The reduced-number meanings follow the traditional vocabulary shared by gematria and numerology.
