Question for Maths/Finance people

If someone has 1 million in a bank account (any currency-say CND) how much interest is realistically paid on it a month?

I’m trying to figure something out after reading abt GB “brain drain” to nations which are first world but have weak exchange rates v GBP.

Say baks pay 3-4% on accounts with over 500K in them.

Thanks
