Compound interest On my Sharp EL 531W calculator, can you tell me how to calculate interest compounded daily for two years at 4.25% on $400?

Fixed deposit calculations can be done by both manual and automatic methods.Now let us figure out the fd calculation in both ways:
1.) Manual Calculation Technique: It is the conventional process to know your Fixed deposit interest calculation. The formula for manual fd calculation is used as below:

Where,A = Final Amount
P = Principal Amount (initial investment)
r = Annual Nominal Interest Rate (as a decimal, not in percentage)
n = Number of times the interest is compounded per year
t = Number of years

2.) Online Calculator Technique: Nowadays online FD calculator is very amazing technique and it is a very useful online tool that helps you to easily calculate your Fixed deposit return. Online FD calculators uses simple technique in which you need to put your amount, tenure, interest rate and can get accurate results instantly. You can easily calculate and compare the interest receivable by changing the deposit amount.

premium X % X time
so 380,00000 X4/100 X 1 year
it calculated as the amount ( premium ) multiplied by the percentage of 100 multiplied by the period in years or parts of a year
so it can be 100 X 25% or 1/4(25/100) by the period (5 years or daily (1/365 of a year)
This is known as simple interest
compound interest is calculated on remaining premium after payment X the interest rate by the day or week or month
so for example 100 X 4/100 X 1/12 is the first calculation for the month and for the next month the calculation will be premium of 80 ( if a 20 payment was made in the month X 4/100 X 1/12 and so on if payment are made on time
pm the other hand if no payment are made then the premium goes up by the interest rate
so for the next month it is 104 X 4/100 X 1/12 and the month after that 108.16 X 4/100 X 1/12.and so on
banks use compound when calculating home loan repayments and simple interest when paying interest on your deposits
( has to be in the bank for 367 days to get the interest paid )

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.

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

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

Assuming the 28k is put in as one lump sum each year and that the interest is compounded annually, then after 15 years I calculate $453,329
You can use the following online calculator to make adjustments, check my calculations, modify any factors, etc...

Your result is for the 6.75% interest compounded monthly. The problem states that the interest is compounded semiannually. This makes a difference in the effective interest rate.

A 6.75% APR compounded semiannually gives an effective interest rate of about 6.864%:
Press 2 , 6 . 7 5 2nd >EFF

Converting this to APR gives about 6.657%:
Press 1 2 , 6 . 8 6 4 2nd >APR

If you use 6.657 for the interest rate instead of 6.75 you should get the correct result.

No solution, but I have the exact same problem with a Sharp EL-531W calculator. Doesn't matter whether mode is degrees, radians, etc., and resetting with button in back has no effect.

Yes you can use it, here is the formula: Y= V(t+ (i/c))^(tc) V=amount put in, t=time, i=intrest rate, c= amount of times it is compounded.
(I know this because I have a TI-83 calculator)

Please see attached image.

The formula in C3 is =C2+((C2*(A3/100))/365). This is replicated down the spreadsheet.
Obviously you would have to put in the daily interest rate.

Hope this helps
