Agree With vs. Agree On
Agree With vs. Agree On separates directly documented constructions and keeps the distinction narrow rather than turning a context-sensitive pattern into a universal preposition rule.
Use agree with for sharing a person’s opinion; use agree on when people reach or share a view about a subject, point, or arrangement.
Key details
Choose the right form

Quick tests
Relationship test
Is the complement the person or view you are in agreement with?
If yes: Use “agree with.”
If no: If people are settling or sharing a position on a topic/arrangement, “agree on” may be the better fit.
Caveat: “Agree” also combines with other prepositions, including “to,” so do not turn this comparison into a universal two-option rule.
Examples
I agree with your explanation.
The sentence expresses agreement with a view.
We agreed on a launch date.
The group settled the date.
We agreed with a launch date.
Better: We agreed on a launch date.
For settling the date itself, “agree on” is the natural construction.
Further guidance
Core difference
Cambridge gives agree with someone and agree on/about a subject when people have the same opinion.
Style Boundary
Agree also takes to for accepting a proposal or arrangement, so the choice depends on the grammatical relationship rather than a single preferred preposition.
