Scientific calculator

You need a financial calculator rather than a scientific one.
I have always used a HP 10bll+ for all my Acca exams.
Not sure if that is the best you can get but I never had a problem with it.

The difference is that financial calculators are pre-programmed with many different financial algorithms (e.g. compound interest payments, margin, mark-up, IRR…).
In a scientific calculator you will find things like cos, sin, tan and so on that are not relevant for Acca.
Of course, you can do everything financial with a scientific calculator but you can do it faster with a purpose-built calculator (provided that you learn how to use it properly by reading the instructions…)

Of course it is!!
What is :”allowed in Acca exams in the uk” supposed to mean?
Acca exams regulations apply equally everywhere. The only calculators which are not allowed are those which can store or display text.
