4000(1 + .06/4)^4*x\n4000(1 +.06/4)^20 = $21227.27\n\n4000(1 + .08/4)^4*x \n4000(1 + .08/4)^20 = $21648.64

the equation for interest is I=p*r*t\n\nso plug in 400 for I, 5000 for P and 4 for T(time) in years:\n\n400=5000*r*4\n\nthen you just solve for R\n\n\nhope that helped

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.

Usually, they go by average daily balance for the month and then compound it every month.  At least this is what my bank does.  I guess this is simulated by compounding it every day and added the interest once a month.\n\nThe daily interest is annual interest divided by 360.

Call the number on your statement.  It is probably a fixed rate account in a variable annuity or variable life insurance policy.

Formula:\n\n\n\nP is the principal (the initial amount you borrow or deposit) \n\nr is the annual rate of interest (percentage)\n\nn is the number of years the amount is deposited or borrowed for.\n\nA is the amount of money accumulated after n years, including interest. \n\nWhen the interest is compounded once a year: \n\nA = P(1 + r)n \n\n\nHowever, if you borrow for 5 years the formula will look like: \n\nA = P(1 + r)5\n\nThis formula applies to both money invested and money borrowed.\n\nFrequent Compounding of Interest:\n\nWhat if interest is paid more frequently? \nHere are a few examples of the formula: \n\nAnnually = P × (1 + r) = (annual compounding) \n\nQuarterly = P (1 + r/4)4 = (quarterly compounding)\n\nMonthly = P (1 + r/12)12 = (monthly compounding)\n\n\nApprox. $716.43 I believe

Choose x to stand for the amount invested at 10%.  The remaining amount would be 15,000 - x.  It's invested at 6%\n\nChange the percents to decimals, multiply them by their amounts, and add them up to get the total interest:\n\n.10(x) + .06(15000 - x) = 1260\n\nDistribute the .06: .10x + 900 - .06x = 1260\n\nCombine like terms: .04x + 900 = 1260\n\nSubtract 900 from both sides:  .04x = 360\n\nDivide both sides by .04: x = 9000\n\nFind the other number:  15000-9000=6000\n\nSo, $9000 at 10% and $6000 at 6%.\n\nHope that makes sense!

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.

I think what you are referring to is called compound interest.  That is when your interest is paid on a regualr basis, like mnthly.  So in the following month you get interest on your principle and the interest you received from the previous months.  This reults in a overall higher rate of return.

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%

Let us suppose interest rate is ‘r’ and the principal amount was ‘P’\nThen for two years;\n\nSimple Interest = 2rP\nCompound interest = P(1+r)^2 – P\nSince we know both the amount of Simple interest and the compound interest we get a set of two simultaneous equations\n\n2rP = 400(1)\nP(1+r)^2 –P = 420(2)\n\nFrom first equation we get \nP=400/2r or P = 200/r\n\nSubstituting in Eq (2)\n\n(200/r)(1+2r+r^2)-200/r = 420\n200/r(1+2r+r^2-1) = 420\n1/r(2r+r^2) = 420/200\n2+r = 420/200\nr = 420/200-2\nr = 2.10-2\nr = 0.10\nSolving for P in eq(1)\nP = 400/2r\nP = 200/r\nP = 200/0.10\nP = 2000\n\nSo the principal amount is 2000.

COMPOUND INTEREST\n---------------------------------\n\n S = P (1 + I) n \n\nwhere:\n\nS = the future value\n\nP = the principal amount\n\nI = the periodic rate of interest*\n\nn = the # of compounding periods for the term of the loan\n--------\n\nFor example,\n\nIf the principal amount is $10,000, the periodic rate of interest is 10% and the # of compounding periods is 6, what is the value at maturity?\n\nS = P (1 + I) n \n\nS = $10000 (1 + .10) 6\n\nS = $ 17715.61\n\nhttp://homepages.cambrianc.on.ca/tutorial/thetutorialcentre/mathscience/math/compound_interest.htm\n\n\nSIMPLE INTEREST \n------------------------------\n\nAt start:\n\nT = P\n\nAfter 1 period:\n\nT = P + Pr = P(1 + 1r)\n\nAfter 2 periods:\n\nT = P + Pr + Pr = P + 2Pr = P(1 + 2r)\n\nAfter 3 periods:\n\nT = P + Pr + Pr + Pr = P + 3Pr = P(1 + 3r)\n\nAfter n periods:\n\nT = P(1 + nr)\n\n--------------------\nWhen money is borrowed, interest is charged for the use of that money for a certain period of time. When the money is paid back, the principal (amount of money that was borrowed) and the interest is paid back. The amount to interest depends on the interest rate, the amount of money borrowed (principal) and the length of time that the money is borrowed. \nThe formula for finding simple interest is: Interest = Principal * Rate * Time. If $100 was borrowed for 2 years at a 10% interest rate, the interest would be $100*10/100*2 = $20. The total amount that would be due would be $100+$20=$120. \n\nSimple interest is generally charged for borrowing money for short periods of time. Compound interest is similar but the total amount due at the end of each period is calculated and further interest is charged against both the original principal but also the interest that was earned during that period. \nhttp://www.learningwave.com/lwonline/percent/interest.html\n\n\n\nhttp://www.aaamath.com/g84-simple-interest.html \na calculater ..

That depends on how often the interest is compounded.

You must add one important detail: is it 4.8% per annum (yearly) or monthly?\n \nIf it's per annum:\n1000 * [1 + 0.048/12]^months\n \nIf it's per month:\n1000 * [1 + 0.048]^months\n \nTo find out how much after 1yr and after 2yrs, subtitute months by 12 and 24.\n \n \n\nIn Reply to the Mar 6, 2006 addition\n  \nLynn, you did say "compounded monthly" and people will almost always take this as "per annun with monthly componding" and almost always, it is. But it's not necessarilly so. It could be 4.8% per month with monthly compounding, for example. Ok, I'm kind of pushing it, but it's still true. You should be aware of these trick questions.\n \nAlso be aware that there are countless ways to calculate interest. I've worked with finance all my life and am a PhD student now and still see new ways once in a while. There are several things that may affect the result and the way to work thru the problem. The kind of interest you are learning now is a very basic form and for now you should only be aware that the way the interest rate is expressed must refer to a period. This period has no relation to the compounding period. Usually, it will be per annum but doesn't have to. For example, my bank informs me of the overdraft interest rates as a monthly rate, it is compounded daily but in a completely diferent way than the one you're learning. So keep in mind that you might be asked a question in which the rate is (for example) 5% per semester with semi-monthly compounding, over a period of one year. That is a legitimate question and will result in more than 10% per year. Good luck.
