"Work out" and "pan out" both describe things turning out well, but they describe two different mechanisms — one is about effort, the other is about a hoped-for result simply landing or not.
"Work out" implies resolution through effort or problem-solving, and it's frequently transitive: you work out a deal, work out the details, work out your differences. "Pan out" is strictly intransitive, implies no effort or deliberate resolution, and is closer to a bet or gamble paying off than a problem being solved.
Work out: effort, often with an object
"We worked out the pricing details after three rounds of back-and-forth."
Someone is actively resolving something here — negotiating, adjusting, problem-solving until it lands. The object ("the pricing details") is what's being resolved.
Pan out: no effort implied, no object possible
"We took the bet on the smaller vendor, and it panned out — on-time delivery and lower cost."

The overlap that trips learners up
A learner who knows "we worked out our differences" cannot substitute "pan out" in the same slot — "we panned out our differences" doesn't exist, because there's no object slot in "pan out" at all. The two verbs aren't variants of the same pattern; only one of them has a pattern that takes an object.
The rule
If the sentence describes someone actively resolving something through effort or negotiation, and names what's being resolved, use "work out." If the sentence is reporting whether a hoped-for outcome happened — with no object, no effort implied — use "pan out."
Practice scenarios
Practice choosing between pan out and work out in situations like:
- describing active negotiation that resolved a specific issue
- reporting whether a bet or gamble delivered on its hoped-for result
- catching a sentence that wrongly gives "pan out" an object
Useful practice phrases:
- "We worked out the pricing details after three rounds of back-and-forth."
- "We took the bet on the smaller vendor, and it panned out."
- "The differences got worked out; whether the partnership pans out is still open."
Effort resolving something, or a hoped-for result simply landing — that's the line between these two.
