This calculator reads a baby's name two ways at once. Numerologically, it reduces the name through the Chaldean letter table and checks that number against the child's Mulank (the birth day) and Bhagyank (the whole birth date). Astrologically, the Vedic Naamkaran rule prescribes the sound a name should begin with, taken from the Moon's nakshatra and pada at birth. The two rules are separate traditions and they frequently disagree - so this page shows both, marks which names satisfy which, and never quietly picks one.
The Vedic naming rule is about a sound. Each of the 27 nakshatras has four padas, and each pada carries one prescribed syllable (akshara); a child born in Ashwini pada 4 is named from 'La'. That rule says nothing at all about numbers.
Numerology is about a total. Each letter carries a value, the letters are added, and the total reduces to a root between 1 and 9 which is then compared with the child's Mulank and Bhagyank. That rule says nothing at all about sounds.
Neither tradition tells you how many numerology points a prescribed syllable is worth, so this page shows no combined score. Where they agree, the agreement is the finding. Where they disagree, the disagreement is the finding.
The name is reduced through the Chaldean table, in which every letter carries a value from 1 to 8 and no letter is ever given 9. The values are added to a compound total, and the total is reduced to a single digit. That single digit is the one compared with the Mulank and Bhagyank, because those are single-digit quantities too.
The Pythagorean expression number is shown beside it and is never merged into the comparison. Pythagorean reduction preserves the master numbers 11, 22 and 33, so it can return a two-digit result that has no counterpart on the Vedic side. Two systems, two scales, reported separately.
Under the strict rule - the one akshara the exact pada prescribes - it is common for no name on a shortlist to reach a friendly number. There are three honest ways forward and this page offers all three: widen to the nakshatra's other three sounds, which the tradition also accepts; choose a name from the numerological list and accept that the sound rule is unmet; or respell a name so that it keeps the prescribed sound and reaches a friendly number.
The third is usually the least disruptive, and every suggested respelling here is checked to leave the pronunciation intact - Lalita and Laalita are the same name said aloud, and only spellings that pass that check are offered.
