Free Greek Gematria Calculator

What Is the Greek Gematria Calculator?

The Greek Gematria Calculator (also known as the Isopsephy Calculator) is a free online tool that converts any Greek word, phrase, or sentence into a single numerical value using the ancient system of isopsephy. Each letter in the Greek alphabet carries a fixed numeric value, and the calculator sums them instantly. Whether you are exploring Greek numerology, studying Ancient Greek gematria, or simply curious about the numeric meanings hidden in names and texts, this free Greek gematria calculator online provides a quick, accurate answer.

Understanding Isopsephy (Greek Gematria)

Isopsephy – from the Greek words isos (“equal”) and psephos (“pebble” or “counting”) – is the Greek equivalent of gematria. The method assigns a distinct number to every Greek letter and then adds these numbers together to produce a total value. Mathematically, the total value is $\text{Total} = \sum_{i=1}^{n} v_i$, where $v_i$ is the numeric value of the $i$-th letter. The resulting integer may hold symbolic or mystical significance, and the system was often used in ancient inscriptions, religious texts, and philosophical works.

Greek Letter Values Table

The table below lists all the letters used in isopsephy, their corresponding numeric values, and the nearest Latin equivalents for transliteration:

Greek Letter (Uppercase / Lowercase)	Numeric Value	Latin Equivalent(s)
Α α	1	A a
Β β	2	B b, V v
Γ γ	3	G g
Δ δ	4	D d
Ε ε	5	E e
Ϛ ϛ	6	—
Ζ ζ	7	Z z
Η η	8	—
Θ θ	9	—
Ι ι	10	I i, J j
Κ κ	20	C c, K k
Λ λ	30	L l
Μ μ	40	M m
Ν ν	50	N n
Ξ ξ	60	X x
Ο ο	70	O o
Π π	80	P p
Ϟ ϟ	90	—
Ρ ρ	100	R r
Σ σ ς	200	S s
Τ τ	300	T t
Υ υ	400	U u, Y y
Φ φ	500	F f
Χ χ	600	H h
Ψ ψ	700	—
Ω ω	800	W w
Ϡ ϡ	900	—

The archaic letters stigma (Ϛ/ϛ), koppa (Ϟ/ϟ), and sampi (Ϡ/ϡ) are included because they occasionally appear in historical gematria calculations.

How to Use the Isopsephy Calculator

Operating the tool is simple:

1. Enter your text in Greek. Type directly if you have a Greek keyboard, or transliterate a word from Latin letters using the table above. You can also copy individual Greek letters from the list provided.
2. The calculator immediately sums the numeric values of all letters.
3. The result appears instantly – the total isopsephy value.

Example 1: “Neuralink”

Transliterate the English word “Neuralink” to Greek: νευραλινκ.
Values from the table: ν=50, ε=5, υ=400, ρ=100, α=1, λ=30, ι=10, ν=50, κ=20.
Sum: 50 + 5 + 400 + 100 + 1 + 30 + 10 + 50 + 20 = 666.

This result is often quoted because of its famous biblical association.

Example 2: “λόγος” (Logos)

The Greek word λόγος was central to classical philosophy.
Letter values: λ=30, ο=70, γ=3, ο=70, ς=200.
Total: 30 + 70 + 3 + 70 + 200 = 373.

Example 3: “Καλημέρα” (Good Morning)

The common greeting Καλημέρα (Kalimera) breaks down as: Κ=20, α=1, λ=30, η=8, μ=40, ε=5, ρ=100, α=1.
Sum: 20 + 1 + 30 + 8 + 40 + 5 + 100 + 1 = 205.

Practical Tips

• The calculator expects Greek characters only. If you enter Latin letters, it will not convert them automatically; you must supply the Greek text.
• Spaces and punctuation are ignored, so you can enter entire sentences as a continuous string.
• The tool is completely free and works instantly in your browser, with no downloads or registration.
