Question about Texas Instruments TI-83 Plus Calculator

How long will it take Wendy's $4000 investment, compounded at 5% annual interest, to earn an additional $2000

Press APPS and select the Finance app. Select the TVM Solver.

Enter -4000 for PV, 0 for PMT, 6000 for FV. Be sure you use the (-) key for PV, not the - key. P/V and C/Y should both be 1 and PMT should be END.

If you want 5% annual interest compounded month, enter 5/12 for I%. If you simply want 5% annual interest, enter 5 for I%. Go to N and press ALPHA ENTER to see the number of periods (months or years according to what you entered earlier in this paragraph).

With simple interest, there is no compounding. To earn 2200.50 interest in six years, you need to earn 2200.50/6 = 366.75 each year. In order to earn 366.75 at 10.5%, you need a principal of 366.75/10.5% = 3492.86.

If the interest is compounded annually then you only need to invest 2682.13.

A=P(1+i)^n, where P is the Principal, i is the interest rate per period, and n is the number of periods.

A=10,000(1+0.075)^3, assuming the interest is compounded annually

For 30 years, we would replace the number of period 3 with a 30.

Good luck,

Paul

But how often is the interest applied, yearly or monthly? If yearly, then the last 3 months don't earn anything at the 29 mo point. So $27624.

If applied monthly the usual trick is to simply divide the yearly rate by 12 = 1.32% per mo. So after 29 mo, $30132

Well if you started with zero in the first year, then $164494, of which $30000 was yours, so earnings are 134494.

If you started with $1000, then $181943, of which $31000 was yours, so earnings are $150943

Invest R10000 in a bank investing at 14% compounded twice a year.

A = P(1+i)^n, where A is the amount, P is the principal or initial investment, i is the interest rate per period, and n is the number of periods.

If the annual rate is 14%, the semi-annual rate is 7%. One year is now composed of 2 6-month periods.

So after one year, we have A = 10 000 (1.07)^2 or 11,449.

Good luck,

Paul

FV = 12,000

PV = -10,000

N = 5

I/Y = 3.71%

PV = -10,000

N = 5

Hmmm, I don't think the problem is with your calculator. I'd be checking the accounting question again as I don't think you've got your annuity question structured right.

4 Year Annuity

14% Annual Interest Rate

Your contributing $4,000 per year over the next 4 years

and you already know the future value is $50,069?

You'd have to make annual payments of $11,878.93 (4 of them) at that annual interest rate to get to a future value of $50,069 (which has a present value of $43,632.24).

Are you sure that the FV isn't the trade in value at the end of the 4 years?
