101.26 is what you'd get for 5% APR compounded monthly for three months. 115.76 is what you'd get for 5% APR compounded yearly for three years. Make sure that the compounding interval and the interest rate are consistent.

final value = principal value x (1+I)^n

I= interest rate for n say 10% it would be 0.10

if n= 1 year then interest rate if

one year interest rate so if 5 years n= 5

if interest rate is monthly then divide year int rate by 12

and increase n by 12 so 5 years equals 60 terms of interest calculation.

cost of equity would be pv + pv * CPI

if CPi was 2.5% as an example

cost of equity for year one= PV + (PV * 2.5/100)

fv = pv*(1+2.5/100)^1

if cpi is different each year then

fv= pv1(1+2.5/100)^1 + pv1(1+cpi2/100)^1 + pv1(1+cpi3/100)^1

If CPI is same for each year then FV = PV (1+0.025)^number of years.

^ 2 is like squared

Hi there,

First make sure all previous amounts stored are cleared by pressing 2nd F MODE.

Then type in the original value 20 000 and press PV.

Type in the interest 13 and press I/Y.

(If i assume that the interest is compounded yearly my calculation is more simple)

press 5 and N

Press COMP FV and your answer will be - 36 848.70

(If I assume that the interest is compounded monthly, i need to input a little bit more data into my calculator)

Press 2nd F I/Y (to get to payments per year) and press 12 and ENT. Press ON.

Then press 5 and 2nd F N and then press N again.

Now calculate FV by pressing COMP FV which should give you - 38 177.13.

Take this value and subtract the PV from it to get the amount of interest earned.

The 107,186.37 is what the future value would be if the interest per month is 0.58%, which is 6.96% per year. Try the following:

2nd [CLR TVM] 1 2 N 7 I/YR 1 0 0 0 0 0 PV CPT FV

As for rounding, you can change the calculator display to any number of digits (up to a limit, of course) by pressing 2nd [FORMAT] and then a number specifying the number of desired digits after the decimal point or 9 for floating decimal.

Did you fix this? I am having the same problem.

What you've done is calculate the future value after 3 months, not 3 years.

Press 1 SHIFT [P/YR] to set the payments per year to one. Now the FV key should give you 115.76

Press 1 SHIFT [P/YR] to set the payments per year to one. Now the FV key should give you 115.76

The I/YR key on the top row, with or without the shift key.

Typing 1 2 5 0 PV 1 5 2 0 +/- FV 4 N I/YR should give you 5.01

Typing 1 2 5 0 PV 1 5 2 0 +/- FV 4 N I/YR should give you 5.01

Hi there,

Firstly, can i recommend resetting the calculator (There is a reset button on the back). (Or in general press 2ndF MODE to clear all the saved data).

Set your MODE to BEGIN by pressing 2ndF FV.

press 180 N

press 9 i/y

press 2ndF I/Y - press 12 ENT (this puts in your compounding intervals).

Press on

press +/- 35 000 PV

press 446 659 FV

Press COMP PMT.

This should give you the answer of -819.23 as expected :)

Hey,

Just found out the answer!

Apparently you can't have both FV and PV positive. Try the calculation with one of them being negative.

You have the payments-per-year set to 12. For this pair of problems, it needs to be set to 1.

Press 2nd [P/Y] 1 ENTER.

Press 2nd [P/Y] 1 ENTER.

PV=1,077,202 while FV=1,000,000 ? I wonder somebody will lent me $1,077,202 and accept to get back $1,000,000 in 10 years later.

Your example's got prob, guy !
