Per this year's Census Bureau report on public school financing, New Jersey schools have total per pupil revenues of $20,531, which puts it fourth nationally. This is 2014 data, the most recent available.
The big surprise is that DC, the perennial leader in this area, remained (barely) under $30,000 in total revenues per student. DC again provides the timely example that more money doesn't solve the schools' problems if the educational model is wrong.
In NJ the difference between the money squandered on urban students is much larger than that spent on real schools with real students; the worst districts spend the most per pupil.
