be well off

1. To be wealthy. Because my grandparents are well off, they very graciously agreed to pay for my education. The Millers must be pretty well off if they can afford multiple trips to Europe like that. They used to be so well off, but that was before the economy crashed and their business closed.

2. To be in a favorable state or situation. If you have a job, you're well off in my book—I've been unemployed for the last six months. Man, you've got a beautiful woman who loves you—trust me, you're well off. Do you know how many hungry kids are out there in the world? You go to bed with a full stomach every night, so you're well off compared to them!
