Question

I am having trouble in personal finance and need to learn how to figure out S=P(1+rt) and P=S(1+rt). Can someone assist me in learning these formulas?

Answer 1

A=p(1+rt)
A=future value
P=present value
R=interest rate
T=time
If you want to find present value
P=A/(1+rt)
If you want to find interest rate
R=[(A/p)-1]divided by t
Finally if you want to find time
T=[(A/p)-1]divided by r
