How much for a private English lesson in Poland?

... in a small town in Western Poland?

50zl per hour, but some charge more and some charge less but this is about the norm

whatever you think the local market is willing to pay given demand, competition and how you want to position yourself

as ukpolska suggests, 50zl is a figure to start with

Are you looking to give lessons or receive them? If it's receive-I'm an English tutor, and I do online sessions via Skype. You can PM me for more details if you need to.

I'm an English teacher and I work in a private school, but someone outside school has asked me if i will give a private lesson.

40zł/45min to 50-60zł/60min, it's up to you

Ah :)

A bit too much for a small town. Check the rates here.

we settled on 70zł for 90 minutes - i think that thats reasonable.

I used to pay 35 zlotys for 45 minutes but not in Warsaw.

Depends on teacher's skills. Different case of polish second year student of english philogy, different of native speaker.
