I am in Zimbabwe and work for a local bank, kindly help me with a mathematical model/formula/computation that i can use in determining FD investment rates to offer our clients, given our Reserve bank isnt guiding us with such.
If you're serious, please provide an example.
As is, your request is incomplete/unclear.
You ask about calculating rates, but give no background.
Your question is a bit like:
how can I set the price of apples if the Head Grocer is on holidays?
