If $4000 is invested in an account for which interest is compounded quarterly, find the amount of?

well, you find out how many installments in 5 years, then you do one, add to total, do the next add to total...etc.\n\n4000*.06=240 240+4000= 4240, and so on

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.

Pretend that she invested x dollars at 6.5% and y dollars at 7%. You know that x+y=5000 (because she invested $5000 total), and .065x+.07y=340 (the amount of interest from both). From there, you are solving a system.\n\nWith a little help from my graphing calculator, I find that x=2000, y=3000.\n\nLet's check. $2000 dollars at 6.5% would give $130, and $3000 at 7% will give $210. $2000+$3000=$5000, and $130+$210=$340.

$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.)

Simple interest is hardly ever used anymore.\n\nIt is certainly compound interest.

The formula for compound interest calculation is  \nFuture Value = Principal (1 + monthly interest rate*12/100 )^no. of years\nHence $100 would become = 100(1+ 1.67*12/100)^5\n= $ 100(1+20.04/100 )^5\n= $ 100 ( 1.2004)^5\n= $ 100 * 2.4924697\n= $ 249.25 (rounded to two decimals)

80,000(1+(.1/4))^(4(5))\n= 131,089.32\n\nso then:\n131,089.32 - 80,000 =\n$51,089.32 in interest.

first, start with how much money you have, then find the rate, and the time\n\nfor example:\nI have $20,000, at a rate of 12% for 36 months. The interest would be $20,000 times .12 times 36.

assume $Y grows at 10% every year. after 1year\ninterest=Y*(1.1^1)-Y\n\nSo after X years\ncompound interest= Y*(1.1^X)-Y\n\nan example: $1000 grows at 10% every year for 20 year will have compound interest of\n1000(1.1^20)-1000=$5727.5   ( as suppose to $2000 which is what you will have if you earn 10% every year but not compound)\n\nAnother one: $1000 grows at 15% every year for 20 year will have compound interest of\n1000(1.15^20)-1000=$15366   ( as suppose to $3000 which is what you will have if you earn 15% every year but not compound)\n\nenjoy

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%

Your question needs clarification.\n\nIf you are calculating simple interest only, then those who answered $4,331.25 are correct.\n\n\nIf interest is being compounded, then the formula is A=P(1+(r/m))^mt where...\n\nP - principle\nr - rate, yearly\nm - number of times compounded (this assumes you are compounding interest monthly)\nt - time, in years\nSolve for A.\n\nA=3500(1+(.095/30))^30*2.5\nA=3500(1.0031666667)^70\nA=3500*1.247718188\nA=4,367.01\n\nSo, compounded monthly it is $4,367.01.\n\n\nCompounded yearly would be $4,391.40. The formula is A=P(1+r)^t.\n\n\n[For information overkill] If you are compounding continuously (using e), the formula is A=Pe^rt, where e=2.7183.  This gets an answer of $4,438.27.\n\n\nALL of this assumes that you aren't paying anything until 30 months down the road.  If you are paying back month-by-month, then you will need to find a mortgage calculator.\n\nEDIT: I just realized that you are probably looking at a car loan.  The link below shows a monthly payment of $131.53 for a total of $3,945.90 over the life of the loan.  This would assume no additional fees were incurred in the loan process.

This may seem tricky, but it's not that hard.  The formula to calculate the monthly interest needs APR (Annual Percentage Rate), and you have the APY (Annual Percentage Yield).  We can approximate the APR from the APY, so, again it's not a big deal.\n\nThe formula is monthly_interest = APR/365 * days_in_month * monthly_balance.  As you know, leaving the monthly interest in your savings account will increase your balance, giving you more interest the next month.  An APY or 4.8% is likely based on an APR of 4.7%.  An APR of 4.7% actually gives an APY of 4.8026%  Confirm the actual APR with your bank.  \n\nUsing 4.7% as the APR and your current balance of $113.94, we get the first month's interest of .047/365*30*113.94 = $0.440152 or 44 cents.  Notice that I assumed the month has 30 days.  Longer months will get you a few more cents of interest.\n\nBest of Luck.
