Is this sentence right?
 

Hello guys! *First post btw :)*

I just started out with speaking Japanese and I could use some support by you! If you could help me it would be awesome!
So I want to say:
'I have money.'
In Japanese. Should I say:

'Watashi wa okane ga aru.'

Again thank you already!

Koekoeka

Watashi no okane ga aru

What does the 'no' after watashi mean? Or doesnt it have an english equivalent?

I was about to say (watashiniha)okane ga arimasu...in brackets only for grammatical purpose coz I doubt you will find it.
Dependng on what your English phrase means I think you can even say okane wo motteimasu.

(But I am a student like you, thus always doubt my words :) ).

I dont think "Watashi no okane ga aru" is good; "no" is the possessive particle, here it would mean "I have my money".

"Watashi ha okane ga aru" is good.

"Watashi ha okane wo motte iru" is also good (and would say better)

I am a student and can be wrong though, but I'm confident :)

This means "My money is there." or "My money exists." or "I have my money (as opposed to someone else's money)."

First of all, you don't need "watashi". Only use it when there could be confusion you are talking about someone else.

I would say "Okane ga aru" or "Okane motteiru".

Wow! Fast replies! Thank you all! I've learned alot by you!

I would say "Okane ga aru" because "Watashi no okane ga aru" translates more to "My money exists" rather than "For me, money exists."

I should say okane ga arimasu!

Hm I agree with MMM, you should say "okane wo motteiru" ^^ there's no need to say "watashi" except if you're with someone who has no money ^^
