What Is Gematria? A Simple Guide to How Gematria Works

Gematria is a system that gives every letter in an alphabet a numeric value. Add up the values of the letters in a word and you get a single number — the word's gematria. The same idea works in any language whose letters can be mapped to numbers. English, Hebrew, and Greek are the three traditions you'll see most often, and a gematria calculator is just a tool that automates the lookup and the addition.

Different traditions use different ciphers, which is why the same word can have several “correct” gematria values depending on which cipher you choose. The math is simple. The interesting part is knowing what the result does — and doesn't — mean.

The procedure is the same in every language:

1. Pick a cipher — a table that pairs each letter with a number.
2. Look up the value of each letter in the word.
3. Add the values together.

That's it. The result is the word's gematria under that cipher. The arithmetic is identical to summing a list of numbers; what changes from cipher to cipher is the lookup table.

Every calculator on this site is transparent about which cipher it's using and shows the per-letter values so you can verify the total by hand.

English ciphers are modern. They came out of nineteenth- and twentieth-century occult and esoteric writing, not the original Hebrew or Greek traditions. The most common English ciphers are:

• English Ordinal — A=1, B=2, C=3 … Z=26. The simplest cipher and the one most people mean by “English gematria”.
• English Reverse Ordinal — Z=1, Y=2 … A=26. Same idea, mirrored.
• English Reduction — after looking up each letter in the ordinal, reduce values above 9 to a single digit (K=11→1+1=2). Sometimes called Pythagorean.
• Sumerian / Simple × 6 — English Ordinal multiplied by 6, popularized in the late 1990s.

Our English gematria calculator shows all four side by side, so you can see how the same word looks under each cipher and pick the one your source is using.

Hebrew gematria is the original. Hebrew letters have done double duty as numerals since at least the second century BCE. There was no separate set of digits for centuries — a Hebrew letter on its own was already a number, and a string of letters was a sum. The standard cipher pairs each of the twenty-two Hebrew letters with a value:

• א 1 · ב 2 · ג 3 · ד 4 · ה 5 · ו 6 · ז 7 · ח 8 · ט 9
• י 10 · כ 20 · ל 30 · מ 40 · נ 50 · ס 60 · ע 70 · פ 80 · צ 90
• ק 100 · ר 200 · ש 300 · ת 400

Hebrew also has five “final” letter forms (ך ם ן ף ץ) that appear at the end of words. In standard Hebrew gematria, finals share the same value as their non-final counterpart — ך equals כ (20), ם equals מ (40), and so on. Some specialized ciphers assign the finals 500–900 instead, but the standard cipher most calculators report does not.

The Greek equivalent of gematria is called isopsephy (literally “equal pebbles”). Greek letters were used as numerals in classical Greece, and the standard isopsephic cipher pairs each letter — including a few archaic numeric symbols — with a value:

• α 1 · β 2 · γ 3 · δ 4 · ε 5 · ϛ 6 · ζ 7 · η 8 · θ 9
• ι 10 · κ 20 · λ 30 · μ 40 · ν 50 · ξ 60 · ο 70 · π 80 · ϟ 90
• ρ 100 · σ 200 · τ 300 · υ 400 · φ 500 · χ 600 · ψ 700 · ω 800 · ϡ 900

Polytonic accents do not change the underlying letter, so the calculator normalizes them before lookup — ψυχή sums the same as ψυχη. Our Greek gematria calculator does this automatically and prints the value of every letter.

Three short examples that show the same idea applied across the three traditions:

Numbers like these are easy to verify by hand. The calculator saves you the lookup, but every total on the result panel is just the sum of the per-letter values.

Gematria can do a few useful things. It connects you to a long interpretive tradition in Hebrew literature. It gives you a reliable, repeatable way to compute a number from a word. It makes certain rabbinic and patristic commentaries — which assume their reader is comfortable with letter values — much easier to follow.

What gematria cannot do is decide which interpretations are true. Two unrelated words often share a value because there are far more English words than there are small numbers, so coincidences are statistically unavoidable. Claims that a matching gematria total proves a hidden code, a prophecy, or a secret connection between two unrelated subjects don't hold up to either basic probability or to mainstream scholarship.

Treat the number as data. Treat any interpretation built on top of it as commentary — interesting, sometimes illuminating, but not self-validating just because the totals line up.

A short checklist when you find a gematria match online:

• Which cipher was used? The same word can have very different totals across ciphers — pick one, stick with it, and say which one you used.
• Is the underlying word right? Spelling, transliteration, and accent rules all change the number.
• Could the match be coincidence? Small numbers will almost always have multiple unrelated word-level matches.
• Is the source overclaiming? Phrases like “hidden code”, “cosmic proof”, or “decoded prophecy” are red flags. Real scholarship is more careful than that.

The calculators on this site report the math and the cipher. Anything beyond that is your reading, not ours.

A fair question to ask of any gematria tool is who decided that A is 1. For the six ciphers this site computes, the answer is either arithmetic you can check yourself or a traditional alphabetical order that long predates any modern source, and it is worth being precise about which is which.

• English Ordinal is the position of the letter in the alphabet: A = 1 through Z = 26. Nothing is interpreted; it is counting.
• English Reverse Ordinal is the same count backwards, A = 26 through Z = 1.
• English Reduction folds the ordinal value to a single digit, so I = 9 but J = 1 rather than 10.
• English Sumerian is the ordinal value multiplied by six, so A = 6 and Z = 156. The name is conventional rather than historical and the arithmetic is the whole of it.
• Hebrew Standard and Greek Isopsephy use the traditional alphanumeric values of those alphabets, in which the letters run 1 to 9, then 10 to 90, then 100 upward. Those assignments are the historical numbering systems of the scripts themselves, not a modern invention.

These tables are this site's own, and are presented as such. No reference work is credited for them, deliberately. It would be easy to attach a scholarly-sounding citation to a letter-value table, and it would be wrong unless that work actually printed the same table. A previous version of the gematria pages on this site did credit a reference work for a table it does not contain, which is exactly the mistake this note exists to avoid repeating.

What that means practically: check the arithmetic rather than trusting the attribution. Every value above can be verified by counting, and every total the calculators report can be verified by adding up the per-letter values they show alongside it.
