(1) For working out the maximum annual percentage rate under a credit contract, the rate must be worked out as a nominal rate for each year, together with the compounding frequency, in accordance with this section.

(2) The maximum annual percentage rate is worked out as follows:

_{}

(3) In subsection (2):

** n **is the number of
repayments per year to be made under the credit contract annualised, except
that—

(a) if repayments are to be made weekly or fortnightly—"n" is to be 52.18 or 26.09, respectively; and

(b) if the
contract does not provide for a constant interval between repayments—"n"
is to be derived from the interval selected for the purposes of the definition
of ** j **(see subsection (4)).

** r **is the solution of the following:

_{}

(4) In subsection (3):

** j **is the time, measured as
a multiple (not necessarily integral) of the interval between contractual
repayments that will have elapsed since the first amount of credit is provided
under the credit contract, except that if the contract does not provide for a
constant interval between repayments an interval of any kind is to be selected
by the credit provider as the unit of time.

** t **is the time, measured as a
multiple of the interval between contractual repayments (or other interval so
selected), that will elapse between the time when the first amount of credit
is provided and the time when the last repayment is to be made under the
contract.

** Aj **is the amount of credit to be provided under the contract at
time

** Rj **is the repayment to be made at time

** Cj **is the fee
or charge (if any) payable by the debtor at time

(5) The maximum annual percentage rate must be correct to at least the nearest 0.001% for each year.

(6) In applying the formulas in this section, reasonable approximations may be made if it would be impractical or unreasonably onerous to make a precise calculation.

(7) The tolerances and assumptions under the code, section 158 to section 160 apply in working out the maximum annual percentage rate.

(8) If the credit contract is a continuing credit contract (within the meaning of the code), the following assumptions also apply in working out the maximum annual percentage rate:

(a) that the debtor has drawn down the maximum amount of credit that the credit provider has agreed to provide under the contract;

(b) that the debtor will pay the minimum repayments stated in the contract;

(c) if credit is provided for payment by the credit provider to a third person in relation to goods, services or cash supplied by the third person to the debtor from time to time—that the debtor will not be supplied with any more goods, services or cash;

(d) if credit is provided for cash supplied by the credit provider to the debtor—that the debtor will not be supplied with any more cash.

(9) For the maximum annual percentage rate—

(a) the amount of credit is the amount (or the maximum amount) required by the debtor; and

(b) the term for which credit is provided is the term (or the maximum term) required by the debtor.
