Israeli public schools (both secular and religious) are free. The chareidi bais yaakov schools for girls are part of the system and are free, except for books and things, which can add up, but obviously nowhere near as high as US tuitions. There are private girls schools where parents pay as well. For boys, if they go to independent talmudei torah or chadarim, they pay tuition, which is minimal, around what takamamash said. Yeshiva ketana (boys’ high school equivalent) is more expensive.
