Time Value of Money Problems

Calculating Future Values

Assume you deposit \$10,000 today in an account that pays 6% interest. How much will you have in five years?

= \$10,000 (FVIF of 6%, 5years)

= \$10,000 * 1.3382

= \$13,382

Calculating Present Values

Suppose you have just celebrated your 19th birthday. A rich uncle has set up a trust fund for you that will pay you \$150,000 when you turn 30. If the relevant discount rate is 9%, how much is the fund worth today?

We know,

Present Value = Future Cash Flow / (1 + Required Rate of Return) ^Number of Years You Have To Wait For The Cash Flow

Given,

Present value = \$150,000 / (1 + .09) ^ 11

= \$150,000 / 2.5804

= \$ 58,130

Therefore,

The present value is thus about \$58,130.

Calculating Rates of Return

You’ve been offered an investment that will double your money in 10 years. What rate of return are you being offered? Use the Rule of 72 to calculate the answer.

Suppose, we spend \$1,000, than according the question the money will be double in 10 years which will \$2,000. So,

Present value = \$1,000

Future Value = \$2,000

Time = \$ 10 year

\$2,000 = \$1,000 * (1 + r)^10

2 = (1 + r) ^10

2(1/10) = 1 + r

r = 7.18%
