New Jersey Statutes Title 18A. Education 18A § 68-11.4

An institution of higher education may make educational loans and may charge and collect interest thereon at a rate not in excess of 1% per month on the first $10,000.00 of the principal sum owing on all such loans for the payment of which a person is liable to the institution in any capacity, and 3/4 of 1% on the excess over $10,000.00 owing on all such loans for the payment of which a person is so liable to the institution of higher education. Interest shall be calculated according to the actuarial method, pursuant to which payments made on the loan are applied first to accumulated interest on the principal amount of the loan and the remainder applied to the unpaid principal balance of the loan in reduction thereof. All payments shall be applied no later than the next day, other than a Sunday or a public holiday, after the date of receipt, and a day shall be counted as one-three hundred sixty-fifth of a year.
