Greek Gematria Calculator
Convert any text into its Greek gematria (isopsephy) score.
Supports Latin transliteration and the archaic Greek letters stigma, koppa, and sampi.
Updated August 12, 2026
Introduction / overview
The Greek Gematria Calculator, also known as an isopsephy calculator, turns any word, name, or phrase into a single number. Every Greek letter has a fixed classical value — from up through the hundreds to and the archaic sampi at 900 — and the calculator adds them all together for you. You get both the running total and a letter-by-letter breakdown, so you can see exactly where the score comes from.
You can type in Greek letters directly, or just use Latin letters — they are transliterated to their Greek equivalents automatically, so test scores exactly like its Greek spelling would.
Who is this for?
- Anyone reading classical Greek or studying how words were assigned numbers in antiquity.
- People curious about the isopsephy value of a name, a motto, or a favorite word.
- Anyone who wants a quick way to double-check a hand-computed score.
How to use / quick start
Type your text
Enter a word, name, or phrase into the “Text to translate” box. Greek letters work as-is; Latin letters are converted automatically. No Greek keyboard handy? Click the letters in the Greek letters panel below the field to type them one at a time.
Read the result
The “Greek Gematria” section shows the total as the Value, with each letter’s contribution spelled out in Letter values.
Adjust and compare
Edit or clear the text and the score updates instantly — try a name, a phrase, or the same word in both alphabets.
A quick example
Type the Latin word test. The calculator transliterates each letter (t → τ, e → ε, s → σ) and sums their values:
So test scores . The two each contribute 300 — repeated letters simply add their value again, just like counting.
Calculation method
The score is the sum of the value of every character in the text:
where S is the total score and v(cᵢ) is the value of the character at position i.
How the Greek letter values work
Greek numerals give each unit (1–9), each ten (10–90), and each hundred (100–900) its own letter — 27 values in all. The 24-letter alphabet is extended by three obsolete letters: stigma (ϛ) = 6, koppa (ϟ) = 90, and sampi (ϡ) = 900.
| Group | Range | Letters and values |
|---|---|---|
| Units | 1 – 9 | α=1 β=2 γ=3 δ=4 ε=5 ϛ=6 ζ=7 η=8 θ=9 |
| Tens | 10 – 90 | ι=10 κ=20 λ=30 μ=40 ν=50 ξ=60 ο=70 π=80 ϟ=90 |
| Hundreds | 100 – 900 | ρ=100 σ=200 τ=300 υ=400 φ=500 χ=600 ψ=700 ω=800 ϡ=900 |
Latin letters are transliterated first
Type in Latin letters and the calculator maps each one to its Greek equivalent before scoring. The letter has no equivalent, so it contributes 0. The mapping used:
a→α b→β c→κ d→δ e→ε f→φ g→γ h→χ i→ι j→ι k→κ l→λ m→μ n→ν o→ο p→π r→ρ s→σ t→τ u→υ v→β w→ω x→ξ y→υ z→ζ
q → (none) = 0
A phrase with a space shows this clearly — Omni Calculator becomes Ο(70) μ(40) ν(50) ι(10) + space(0) + Κ(20) α(1) λ(30) κ(20) υ(400) λ(30) α(1) τ(300) ο(70) ρ(100), which totals .
Two things that might surprise you
Case doesn’t matter
Uppercase and lowercase letters score identically, so TEST, Test, and test all give 805.
Greek accents are ignored
Accented letters count as their base letter, so Καλημέρα and Καλημερα both total 205. Spaces and punctuation inside the text contribute 0.
Frequently asked questions
Why does the Latin letter q give 0?
The transliteration table has no Greek equivalent for q (the Greek alphabet has no letter that matches it), so it simply contributes nothing to the total. Only the letters listed in the mapping produce values.
Will an accented Greek word change the value?
No. Accents are ignored, so Καλημέρα (with the accent on the epsilon) and Καλημερα (without it) both total 205. The calculator scores the base letter.
Is this the same as the Gematria calculator?
Not quite. This page uses the Greek isopsephy table (α = 1 … ϡ = 900). The separate Gematria Calculator on this site works with the Jewish (Hebrew), English, and Simple systems, which assign numbers differently — the same text will usually produce a different score in each system.
Limitations
- •The calculator scores Greek and Latin letters; characters from other alphabets, numbers, and symbols contribute 0.
- •It converts text into a number only — there is no reverse direction from a value back to a word.
- •Because case and accents are ignored, two different spellings can share the same total, which is expected for this kind of counting.
- •The numerical “meaning” people attach to a score is a matter of tradition and interpretation, not mathematics. This tool only computes the sum — it does not interpret the result and makes no claim that a word’s value carries hidden significance.
