This is called the Dark L vs Light L, and it's one of the defining features of casual American English. It comes out as BEH·nuh·FIH·shuhl. Stress falls on the third syllable — keep everything else short and quick.

Common pronunciation mistakes in American English.
The textbook way isn't wrong — it's just not how anyone actually says it.
01
Treating every L the same.
The L in "beneficial" is a dark L — the back of the tongue rises toward the soft palate, adding a small "uh" quality before the L. Dark L adds a small schwa-like "uh" before the L. The back of the tongue lifts toward the soft palate.
beneficial→BEH·nuh·FIH·shuhl
02
Stressing the wrong syllable.
Stress falls on the third syllable, not the others. Stretch FIH — keep everything else short and quick.
BEH·NUH·fih·SHUHL→BEH·nuh·FIH·shuhl
03
Pronouncing the unstressed syllable too fully.
Don't pronounce the first syllable too fully. The unstressed syllable reduces to a schwa — the lazy "uh" sound — in casual speech.
beh·NUH·FIH·shuhl→BEH·nuh·FIH·shuhl
Questions
Questions people ask about this.
How is "beneficial" stressed in American English?
Stress falls on the third syllable — say "FIH" with a longer, fuller vowel and keep every other syllable short and quick. The respell "beh-nuh-FIH-shuhl" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.
Why does the second syllable in "beneficial" reduce to "uh"?
Unstressed syllables in American English collapse toward a schwa — a lazy, neutral "uh" sound. The full vowel is what textbooks teach, but in actual American speech every unstressed vowel reduces. The respell "beh-nuh-FIH-shuhl" shows the reduced form so you can hear the casual rhythm directly.
Is the American pronunciation of "beneficial" different from British English?
American English uses different vowel shapes, a relaxed retroflex R, and connected-speech tricks like flap-T and glottal-stop T that British Received Pronunciation generally avoids. The respell "beh-nuh-FIH-shuhl" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
