n
PV is starting amount; r is rate; n is number of periods.
FV=PV(1+r)n=1(1+0.05)20=2653.3dollars
Where:
- A = Future value
- P = Principal amount
- r = Annual interest rate
- n = Compounding frequency
- t = Time in years
This formula shows how investments grow over time.
Simple Interest Formula
For basic interest calculations:
I=P×r×t
Where:
- I = Interest earned
- P = Principal
- r = Interest rate
- t = Time
Loan Payment Formula
