did the job for free/free of charge/for free of charge

[Tan Elaine]

1. I did the job for free.
2. I did the job for free of charge.
3. I did the job free of charge.

Which is the correct sentence?

Thanks.

Well, i am a student.

Sentence 2 is wrong.

Sentence 1 and 3, both are right.But in my opinion sentence 3 is better because it is more clear. You can also write it in this way.

"I did the job free of cost"


You are welcome.

Right, 2 is wrong.

[Tan Elaine]

Thanks, Konungursvia

Can I say "I did the job free of cost", as suggested by Nekbyte?

Thanks again.

[Doran]

I did the job free of charge sounds most professional.

[Tan Elaine]

Thanks, Doran.

[konungursvia]

Yes, free of cost is probably inaccurate, as it implies no consideration was given up by the doer of the favour.

Thanks, Konungursvia.
