You need to know the interest rate in order to find the amount in the account after 4 years.\nLet r = interest rate\nA = 8000(1+(r/12))^(4*12)\nA = 8000(1+(r/12))^48  Now plug in the r.\n\nTo double:\n2 = (1+(r/12))^(12n)\nTake the natural log of each side\nln(2) = (12n)*ln(1+(r/12))\nn = [ln(2)]/[12*ln(1+(r/12))] \nnow plug in r and simplify.

Use the compound interest formula:\n\nA(t) = A (1+r/n)^(nt)  where A(t) is final value, A is starting value, r is interest rate, n is number of times interest is counted in a year, t is number of years. In this case we want to figure r.  Thus,\n1690 = 1255 (1+ r/4)^(2.75)(4)\n1690/1255 = (1+ r/4)^(11)\n1.3466 = (1+ r/4)^(11)\n(1.3466)^(1/11) = (1+ r/4)\n1.0274 = (1+ r/4)\n.0274 = r/4\nr = .1096 or 10.96%

$3156.19 compounded annually after four years with an initial deposit of $2500.00 at a 6% interest rate.  (The shortcut to this calculation is to take $2500 and multiply it by 1.06 four times.)

I have found the best way of saving.  I was able to put away approximately $8000 in 18 months.  Look for www.sharebuilder.com.  Its an investment site.  You can purchase stock for $4.00, no matter how much stock you buy.  Do some research.  I chose companies based on the products i use in my daily life.  I found it be fun to save and also enjoyed shopping for new stocks.  The dividends usually pay better than any savings account, so give it a try.  It worked for me.

OK, I have been in banking for 13 years and I cannot understand your question- Am going to try to explain what\nI THINK I understood. \n3 month cd or treasury bills, the rate you are quoted is the APY 4% - that is the annual percentage yield - the interest you would make on that money if it was to stay in that account for 12months at that rate. But since it is a 3- month, you will have to take the money out and invest it in something else. You cannot compound it because the deal expires after 3 months - Now does that make sense ?

An Interest Rate of 5.000 % compounded Annually\nWith an Initial Amount of $ 4000.00 over an 8 year term:\n\nYr   Ending Balance\n1    4200.00\n2    4410.00\n3    4630.50\n4    4862.02\n5    5105.13\n6    5360.38\n7    5628.40\n8    5909.82\n\nFinal Savings Balance: $ 5909.82\nInitial Investment plus Monthly Contributions: $ 4000.00\nTotal Interest Earned: $ 1909.82\n\nThis should answer your specific question, however, please know that most banks compound interest daily in that scenario you would have earned $ 1967.13 for a total of $5967.13.\n\nHope this helps!

First, pay off any and all of your debts leftover from it. Second, treat yourself to something nice. If you don't want to and/or have many leftover after that, third, you can put that money into a high-interest bearing CD for 2 or 3 years yielding 4 or 5%. I would normally suggest a mutual fund with moderate risk (60% stocks/40% bonds) but the way the markets are right now, it may be a mistake. If you want a promising return, put the money into a IRA and either invest in mutual funds or individual stocks. Some good mutual funds right now are probably International Stocks/Bonds, US Bonds, Money Market Funds, and Balanced funds (containing bonds and equities).

It is already been pointed out that the 4.23% is an annual rate.  Banks compound interest daily using the annual rate divided by 360.  This means that if you put $20,000 in the bank for a year, you should have:\n\n$20,000 * (1+.0423/360)^365 = $20,867.36\n\nat the end of the year.  That averages out to $73.03 per month (though it is less in the early months and more in the later months).

to be able to solve this, first you have to determine the amount of money in the fund after 30 years of annual deposit. to solve this you'll use the formula for annuity, which is,\n\nP = A [1 - (1+i)^-n] / i\n\nP = is the pricipal, in this case this would be the amount of the fund after 30 years.\n\nA = is the annual withdrawal, which is 50,000\n\ni = is the interest rate, which is 10%\n\nn = is the number of years, in this case it would be 20 years\n\nsubstitute the values of A, i, and n\n\nP = 50,000 [1 - (1 + .1)^-20] / .1\n\nP = 425678.19, this would be the amount of the fund after 30 year\n\nfrom this you can get the annual deposit in the account, you'll be using this formula,\n\nF = A [(1+i)^n - 1] / i\n\nF = is the future amount, in this case it would be the amount of the fund after 30 years, which is 425678.19\n\nA = is the annual deposit, which we are looking for\n\ni = is the interest rate, 10%\n\nn = is the number of years, this time it would be 30 years\n\nsubstituting,\n\n425678.19 = A [(1+.1)^30 - 1] / .1\n\nA = 2587.80

If you pay on 07/01/06, ie loan term 1 year and 3months, the interest  should be $475.46. \n\nBut hope the person who calculates it agrees with the three above.

100 Rs become Rs 200 in 8 years if we add 12.5 Rs every year. So rate of interest should be 12.5 %

depends how many stocks and which industires ther invested in.... i have invested 10,000 CDN dollars  and in just 6 months it has almost doubles, (18,256), however currently i have only made 2,500 in these 3 months, it fluncuates

well, you didn't mention the compounding factor, so....\n\nsimple interest\nA sub t is the value (amount) after "t" time\nP is the initial amount invested\nr is the interest rate\nt is time ( in years)\n\n    A sub t  = P ( 1 + r) ^ t\n\nfor compound interest rate\nn is the number of times that the interest is compounded per year\n\n    A sub t = P ( 1 + r/n) ^ (n*t)\n\n\nnow, you have another problem...\nsome CDs only pay interest yearly....\nsome quarterly, some monthly...\nsince your interest rate is different from your APR, \nI'll assume a monthly compounding\n\n     Amt = $2000 ( 1 + (.0489/12)) ^ (12* (11/12))\n\nnote: the  time is 11/12 because interest is figured on a yearly basis and 11 months is 11/12 of a year\n\n  if my calculator does not deceive me\nyou should get   $2091.50

It naturally depends on what your starting capital is - and what your investment horizon is. Thus if you already have $1mn in the bank, and you leave it in a check account which yields 1% p.a., then after one year the bank will add $10,000 to your account :)

First, I should not that the "yield" I have been reporting is the interest earned.  Add $10,000 for the total amount in the account at the end of the investment period.\n\nSecond, you wrote the formula incorrectly.  The formula for continuous compounding has to include the interest rate, so\nA = Pe^(rt)\n\nGiven the information from the previous question ($10,000 at 10% for 2 years), continuous compounding would yield $2,214.03.\n\nIf we know that the bank returned $15,000 on a $10,000 deposit at 10%, the length of time must have been 4.05 years.\n\nIn 6.93 years, a deposit will have doubled.\n\nI apologize for the delay on responding to these questions--I have been on vacation.

There are countless ways to reach $2 million, but each would require substantial investment (either initially or over time) or interest or other increases in your investment which are many times the normal return.  An interesting rule to compute how your investment increases is the rule of 72.  Your investment money doubles in accordance with the rule of 72.  An example is, it takes 7.2 years for money to double if it is earning 10% interest (7.2x10=72).  If you are only earning 6% interest then it will take 12 years for your money to double (6x12=72).

it depends if you are going to invest it take the up front. your opportunity cost of not getting even the modest 3.5% gain from a CD would be worth the getting the 4mil up front. if you plan or know your going to go nuts take the over time so at least you cant blow it all at once
