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

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.

### An original investment of 10,000 earns 7.50% interest compound continously, What will the investment be worth in 3 years? 30 years?

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

### COMPOUND INTEREST

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

### Compound interest

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

### I want to invest R10000 in a bank investing at 14% compounded twice a year

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

### We are not obtaining the correct answer when computing the I/Y. The problem is N=30, PV=-500, PMT = 0, FV = 10000. We are getting 126.01

Since you didn't specify what result you were expecting, I can only guess at what you want.

The answer is correct assuming 12 periods per year. To have 500 increase to 10000 in 30 months, you need an annual interest rate of 126%. For a more realistic result, set the number of periods per year to one by pressing 1 SHIFT [P/YR] then repeat the calculation. This will produce 10.5% for the annual interest rate.

Alternatively, if the interest is compounded monthly, specify 360 for N. This will give a value closer to 10% annually, compounded monthly.

### I want to invest \$5000 for 10 years through internet at 9% , how much would i get in return?

FV=PV (1+(i/12)^12n
Assuming it's compound interest.
FV=Future Value i= interest Rate n=interest period PV =Present Value
\$12,260

### What buttons do I push in what order to figure compound interset. if I start with\$15,000.00 at 6% interset for 25 years. I am on a texas instrument ba 2 plus

If the interest is compounded monthly:

2nd [CLR TVM] (clear any existing results)
1 5 0 0 0 _/- PV (present value, negative because you're paying it out)
6 I/Y (annual interest rate)
25 2nd [*P/Y] N (25 years)
CPT FV (compute future value, see 66,974.55)

If the interest is compounded annually:

2nd [CLR TVM] (clear any existing results)
1 5 0 0 0 _/- PV (present value, negative because you're paying it out)
6 I/Y (annual interest rate)
2nd [P/Y] 1 ENTER 2nd [QUIT] (one compounding period per year)
25 N (25 years)
CPT FV (compute future value, see 64,378.96)

### I have a TI30XA and i'm trying to use it to find the balance of a compound interest problem. the problem is \$5000 is invested at an annual interest rate of 6% for 10 years how can i use the calcuator find...

A = P(1 + r/q)nq is the formula you use. first write it all out, where P is the principle or \$5000, r is the rate of 6%, q is the times per year so it would be 12 if done monthly, and n is how many years which would be 10. hope this helps.
