Yes, there is a fixed monthly plan fee on each instalment plan. This monthly plan fee will be charged each month that the plan is active.   When a new plan is created, the term and fee options that are available will be shown, where Card Members can decide what works best for them. Until 30 September, the fee is fixed at 0.73% of the starting plan balance for all cards except the LOw Fee Rate and Essential card, which will incur a fee of 0.42%. Post this, the percentage fee of the starting plan balance will range from 0.42 to 1.04%, dependent on the type of American Express card held by the Card Member.
