Where can I find a compound interest table that shows from 3% to 10% over 40 years?

I would just use Excel to produce such table.

That depends on how often the interest is compounded.

The formula is \nI = Prt,\nwhere P is the principal, r is the interest rate and t is the number of years.\nThus,\nI = 400(.11)(1)\n= 44

Any major financial news site or paper will have them.\n\nhttp://www.bloomberg.com/markets/rates/

Yahoo! Finance, of course.\nhttp://finance.yahoo.com/q/hp?s=%5EDJI\nYou can set the date range or download it to Excel.

This website gives return on the  S&P 500 for 1,3,5, and 10 years at the bottom of the page.  Since 1926 it has returned ~10.4% a year.

The equal, annual payment for years 24 - 40 would be $40.\n\nIt's a multi-step process. First you must find the present value of the security at the end of year 23 - which is $364.87. Then you can find the payment amount using the PMT formula in Excel. The rate =.08, the NPER=17 (number of periods), the PV=$364.87 (present value), the FV=0 (future value) and the type=0 (payment at end of period) for an answer of $40.00049067.

I = Prt\nwhere I is the interest, P is the principal, r is the interest rate, and t is the time (in years)

Microsoft Excel can help with these kinds of calculations.  Though, an interest formula like this fails to take into account future additions to the principle of your retirement account.  Most people take some of each paycheck and put it into a retirement account rather than depositing a lump sum and forgetting about it.\n\nDon't forget to factor in inflation and taxes somehow!

if interest is compounded daily, don't forget to...\n\n1.  divide 5.16% by 365 to get the daily rate\n2.  use 30 days as your period "n"\n3.  don't use the avg daily balance.  you must use the initial principal balance at the beginning of the 30 day period.\n\ni haven't worked it out, but if your formula is correct, the future value will work.\n\nif you have a business calculator (preferrably from HP)\n\nPV = initial principal balance\ni = 5.16% divided by 365 days\nn = 30 days\n\nsolve for FV

one formula you can use is\n\nF = P(1 + i)^n\nwhere,\n\nF = future worth of the money\nP = present worth of the money\ni = interest rate\nn = number of years\n\nsince the future worth of the money will be twice of the present worth, then we can say that,\n\nF = 2P\n\nusing this in the formula you'll come up with,\n\n-> 2P = P(1 + i)^n  \n(divide the whole equation by P)\n-> 2 = (1 + i)^n \n(n is 20 years)\n-> 2 = (1 + i)^20\n(raising the whole equation by 1/20)\n-> 2^(1/20) = 1 + i\n-> 1.035264 = 1 + i\n-> i = 0.035264\n-> i = 3.5264%

I'm not a teacher, but I came across this site: www.dinkytown.net\n\nIt has over 250 types of financial calculators.  I used the one that showed how overpaying one mortgage payment would factor out through the life of the loan.  It was a great tool to see the power of compounding interest or the reverse of that--how much you can save by paying a little extra now translating to big savings later.

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.

Try this web site\n\nThey have a calulator to adjust prices to different years.

There is not enough information in your question to determine what it is you are trying to find out.\n\nDo you mean to get your $30 back? If it is a dividend of $3 once a year then you would get your money back after ten years.

You will use the formula\nA = Pe^(rt)\nA = 25,000\nsince the question is asking for how long, this means you are looking for t.\nYou need to know the interest rate (r) and the principal (P).
