How they differ

遅れる describes being late or being delayed relative to a schedule (often an outcome), while 遅くなる emphasizes a change in timing — that something or someone will be later than before — and is used more for the time itself or the state becoming late rather than an external delay.

When to use each

When to use 遅れる: Prefer 遅れる when you want to say someone or something is delayed or will not arrive on time.

When to use 遅くなる: Prefer 遅くなる when you want to say that the time or someone's schedule will become later (e.g., 'I'll get home late').

Side-by-side examples

  1. 電車が事故で遅れる。

  2. 今日は帰りが遅くなりそうだ。

Register & nuance: 遅くなる is neutral and commonly used in everyday spoken Japanese.
