What is Compound Interest?
Compound interest is the interest calculated on the initial principal and also on the accumulated interest of previous periods. It allows your investment to grow faster because interest is earned on both the principal and the interest.
Formula:
A = P × (1 + r/n)(n×t)- A = Total amount after time t
- P = Principal amount
- r = Annual interest rate (in decimal)
- n = Number of compounding periods per year
- t = Time period in years
