幸虧 xìngkuī幸亏 xìngkuī is neutral and general — any stroke of luck qualifies. 多虧 duōkuī多亏 duōkuī narrows the credit to someone or something specific, and can attach to a bare noun or pronoun.
虧得 kuīde亏得 kuīde reads as the more literary register of both — until a stray 還 hái还 hái or 竟然 jìngrán竟然 jìngrán flips it into “fancy that,” a dry, reproachful jab.

虧得 kuīde亏得 kuīde — the word with two faces
As a literary stand-in for 幸虧 xìngkuī幸亏 xìngkuī or 多虧 duōkuī多亏 duōkuī, 虧得 kuīde亏得 kuīde is sincere. But add a 還 hái还 hái or 竟然 jìngrán竟然 jìngrán, and the same word turns into dry sarcasm — “fancy that,” mocking someone for falling short of what their role or claim should guarantee.

2 Common Mistakes
These three words look interchangeable — until structure or tone gets in the way.
❌
幸虧你，我才找到這份工作幸亏你，我才找到这份工作
✅
多虧你，我才找到這份工作多亏你，我才找到这份工作
幸虧/幸亏 xìngkuī幸亏 xìngkuī must combine with a full clause describing the lucky situation — it can’t attach directly to a bare pronoun or noun the way 多虧/多亏 duōkuī多亏 duōkuī can.
❌
虧得你考了滿分，真厲害亏得你考了满分，真厉害
✅
多虧你這麼用功，才考了滿分，真厲害多亏你这么用功，才考了满分，真厉害
Without a marker like 還/竟然 hái/jìngrán还/竟然 hái/jìngrán to signal irony, 虧得 kuīde亏得 kuīde can default to sounding sarcastic in a compliment. For a sincere compliment, 多虧/幸虧 duōkuī/xìngkuī多亏/幸亏 duōkuī/xìngkuī avoids the ambiguity entirely.
