How the Name Compatibility formula works (simple breakdown)

Under the hood, this calculator turns the letters of both names into numbers, blends them together, and then compresses that into a clean 0–100 score. It’s not astrology, psychology, or science – it’s structured, playful math.

First, both names are cleaned so the calculator is fair: only A–Z letters are used, everything is converted to uppercase, and extra symbols or emojis are ignored. “Alex 😊” becomes “ALEX”, “O’Connor” becomes “OCONNOR”. This keeps the math consistent.

Each letter gets a simple alphabet score: A = 1, B = 2, C = 3 … Z = 26. The calculator adds up the values in each name to get a name total. Longer names naturally carry more “weight”, but extra logic later prevents long names from automatically winning.

The totals for both names are added together and then wrapped into a 0–100 range using a modular step (a fancy way of saying “if it goes over 100, loop it back around”). This base score gives a first compatibility reading based purely on the letters used.

Names that share a lot of letters (like “Liam” and “Mila”) get a synergy bonus because they look and sound naturally close. Names with similar length also get a small bonus – “Leo” and “Mia” feel more balanced than “X” and a very long name. On the other hand, extremely unbalanced vowel–consonant patterns between the two names can slightly reduce the score, to keep things interesting.

If you pick a context like “Crush / dating vibes”, “Friends / BFF energy” or “Coworkers”, the calculator adds a very small adjustment to help the text feel more specific. This does not drastically change the score – it just changes the flavor of the explanation (for example, more romantic for “crush”, more teamwork-focused for “coworkers”).

• 85–100: Very strong name match – the combo looks and sounds naturally satisfying. Great for fictional couples, ship names, duo channels or character pairs.
• 70–84: Strong compatibility – letters and rhythm play nicely together. You could easily imagine the two names side by side on invites, credits, or social bios.
• 50–69: Mixed but interesting – not a perfect mirror, but the contrast itself can be fun. Think chaotic besties, rivals, or “opposites attract” stories.
• 0–49: Low match on this particular formula – but sometimes the best duos are the ones that don’t look “perfect” on paper.

Imagine “Liam” and “Mila”. They share the same letters, so their shared-letter bonus is high and their lengths are identical. That nudges the score upward. Now consider “X” and “Anastasia” – the letters barely overlap and the lengths are wildly different, so the score tends to be lower. In both cases, the tool is measuring name aesthetics, not emotional reality.

Frequently Asked Questions

• Is this a real compatibility test?

  No. This is a playful name-based calculator inspired by numerology-style games and personality quizzes. It does not measure feelings, values, or relationship skills – just how two names combine according to a fun formula.

• Do longer names always get higher scores?

  Not automatically. While longer names can have larger raw letter totals, the score is wrapped into a 0–100 range and adjusted using shared letters, length balance and vowel/consonant patterns. Short names can still do very well, especially when they sync nicely together.

• Can I use this for baby names or brand names?

  You can absolutely use it for fun inspiration – for baby names, couples names, character names, or brand ideas. Just keep in mind it’s entertainment-only. For serious decisions, consider meaning, culture, pronunciation and personal taste too.

• Will changing spelling or using nicknames affect the result?

  Yes. This calculator is letter-based, so each spelling is treated as its own name. “Katherine” vs “Catherine”, “Jon” vs “John”, and nicknames like “Liz”, “Lizzy” or “Eliza” will all give slightly different scores. That’s part of the fun – experiment and compare.

• Does a low score mean we shouldn’t be friends or date?

  Definitely not. Real compatibility depends on communication, values, respect, kindness and a thousand tiny choices over time. A name formula can’t see any of that – it only sees letters. Treat low scores as a meme, not a verdict.

• Are my names sent to a server or used for training AI?

  No. This calculator runs fully in your browser. The score is calculated on your device, and saved results are stored only in your local storage. Nothing is uploaded, and no AI model is called in the background.

Fun ways to use your Name Compatibility score

• Post side-by-side screenshots of different spellings and ask followers which one “feels” like the real match.
• Run it at parties and let people test their crush, their best friend, and their favorite fictional ship.
• Compare your name with celebrities, characters or historical figures to see which combo gets the highest score.
• Test baby-name ideas or brand names and share the funniest results as a light-hearted “vibe check”.
• Create “name wars” in group chats: everyone runs their name pair and posts the score + explanation.
