This is another detail where earlier and later calculators differ. The first business oriented device, the HP80, had its five TVM keys in the order n i PMT PV FV. So did the HP22, as well as this annuity program for the HP65. Later models however used n i PV PMT FV (which seems a bit more logical). This still is the standard today.
