School in Frankfurt

If you are only concerned about cost, go for public schools (which are free). Many have (also free) preparatory classes to bring foreign kids up to the needed levels. Kids learn fast: At only 7 years of age, after 6-  12 months yours will be more fluent in German than in your language.
Some private schools are subsidized by the organization that runs it (e.g. church, or EU) and may thus be cheaper, but none is cheap - budget at least €1000/month (and count yourself lucky if you get a place in a cheaper one).
The teaching quality is not usually better than public schools - unless you opt for one of the elite boarding schools that cost several thousand per month.

Thanks Beppi. Where should I connect for public school admission? Can't see it on google.!!.

Of course such information is finable at Google.  The thing is that it’s not possible to know your kid’s eventual school until you have found a place to live. Frankfurt is a large city and there are many schools.

Thanks.
Will he be admitted to school as he doesn't know German as a language? How difficult will it be from kids perspective?

It’s a legal requirement for kids to go to school and the public schools have to take them – and find a way to integrate them. From your side you should not wait to start getting him German lessons. Likely he’ll have to be in a special program to concentrate on langue which might basically cost him a year academically. But you will have to discuss this with the school.

For school admission, contact the individual school - or the local "Schulamt" if you didn't decide on a school yet.
As Tom wrote above, depending on your kid's age and abilities the preparatory class will "cost" him/her 6-12 months.

"langue" should be " language"...

Thanks a lot!!
