A brilliant young scientist is killed in a plane crash

Subject:FinancePrice:2.86 Bought8

A brilliant young scientist is killed in a plane crash. It is anticipated that he could have earned $370,000 a year for the next 40 years. The attorney for the plaintiff's estate argues that the lost income should be discounted back to the present at 5 percent. The lawyer for the defendant's insurance company argues for a discount rate of 11 percent.

What is the difference between the present value of the settlement at 5 percent and 11 percent? Compute each one separately.

The difference is $3036973.15.

Step-by-step explanation

This is an ordinary annuity.

The present value formula for an annuity is as follows;

Present value=payment*(1-(1+r)-n/r)

We are given the following data;

Payment=$370,000

Interest rates(r)=5%,11%

Number of periods(n)=40 years

Discount rate of 5%

Present value=370000*(1-(1.05)-40/0.05)

=370000*17.15908635

=$6348861.95

Discount rate of 11%

Present value=370000*(1-(1.11)-40/0.11)

=370000*8.951050817

=$3311888.802

The difference is as follows;

$6348861.95-$3311888.80

=$3036973.15

The difference between the two discount rates is $3036973.15.
