4. Investment planning is something that many people need to be aware of. Planning for your future requires research because bad choices can be very costly. Interest paid on money invested is usually in the form of compound interest. The formula to calculate compound interest is: T = P * (1 + r)n T is the total value of the investment, P is the principal sum invested, r is the interest rate per time period converted to a decimal (for example, 5 % is 0.05), n is the number of time periods.
