How do you claculate APR?
338417
The APR calculation can differ from bank to bank and it is like a "3 page calculation". At least that's how my bank's interest group explained it to me when my group was trying to answer client's questions.\n\nIt's obviously not that bad, but this link gives you a good idea:

For compound Interest.\nA = a*(1+p/n)^(y*n)\n\nA = Final amount\na = Original amount\np = interest percentage (in this case = 6.5/100)\nn = no of times calculated/year\ny = no of years\n\n18000 = 9000(1.0325)^2y\n2 = 1.0325^2y\n\ny = [Log(with base 1.0325) 2] / 2\n\nRemembered anohter thing to help...Change of base rule\n\nlogx(b) = loge(b) / loge(x)\n\nSo next step would be..\n\ny = [ln(2) / ln(1.0325)]/2\n  = 10.836\n~~ 11 yrs

Let's define some variables for the equation.\n\nD = monthly deposit ($200)\nr = annual interest rate (10% is 0.1)\nn = compound frequency (12 months in a year)\nA = account balance\ni = compounded interest\n\nLet's start the account this month, or month 0.\n\nA(0) = D\n\nOne month later, you make another deposit and earn some interest. But you only earn 1/12 of the 10% with you existing balance, which is r/12.  \n\nA(1) = D + A(0) + i(1)\n\nwhere, i(1) = A(0) * r/n. Which makes\n\nA(1) = D + A(0) + A(0) * r/n , or\nA(1) = D + A(0) * (1 + r/n ), or\nA(1) = D + A(0)*R, if R = 1 + r/n, but A(0) is D, so\nA(1) = D + D*R\n\nTwo months later, you make another deposit and earn some interest on the balance A(1). Similarly calculating,\n\nA(2) = D + A(1) * R, or\nA(2) = D + (D + D*R) * R, or\nA(2) = D + D*R + D*R^2\n\nKeep on going to three months later, \n\nA(3) = D + A(2) * R, or\nA(3) = D + D*R + D*R^2 + D*R^3, or\nA(3) = D * (1 + R + R^2 + R^3)\n\nFollowing this pattern, k months later, we get\n\nA(k) = D * (1 + R + R^2 + ... + R^k)\n\nNow, let's calculate the general expression (1 + R + R^2 + ... + R^k) in a closed form.\n\nLet S = (1 + R + R^2 + ... + R^k). Multiply R on both sides, we get\nS*R = (1 + R + R^2 + ... + R^k) * R, or\nS*R = R + R^2 + ... + R^k + R^(k + 1)\n\nSubtracting the two equations S*R and S on both sides, we get\n\nS*R - S = R + R^2 + ... + R^k + R^(k + 1)  - (1 + R + R^2 + ... + R^k)\n\nNotice the terms R all the way through R^k on the right hand side are cancelled and only left with R^(k + 1) - 1. So we have,\n\nS*R - S = S(R - 1) = R^(k + 1) - 1\n\nDividing (R - 1) on both side, we get\n\nS = [R^(k + 1) - 1] / (R - 1)\n\nRewriting the account balance at month k,\n\nA(k) = D * (1 + R + R^2 + ... + R^k), or\nA(k) = D*S = D * [R^(k + 1) - 1] / (R - 1)\n\nNow, 26 years make 26 * 12 = 312 months. But since you start with 0, so your k is actually 311. R = 1 + r/n = 1 + 0.1/12, and D = 200. So\n\nA(311) = 200 * [(1 + 0.1/12)^(311 + 1) - 1] / (1 + 0.1/12 - 1), or\nA(311) = 295667.15330119169 = 295667.15 (round to nearest penny)

I assume you mean arp in command propt, there isa full list of functions and switchs if u type apr/help at the command prompt

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%

Calculating the Effective Annual Rate\n\nBasic Financial Calculator Suppose that you have determined that the monthly rate of return on a certain investment is 0.21307991 (%). That's the monthly rate. You can multipy that number by 12 to get the nominal annual rate of about 2.55696%. But suppose you would like to know the effective annual rate (EAR)?\n\nThe effective annual rate is the annual interest rate that would yield the same result if interest was compounded annually rather than monthly.\n\nThe formula for calculating the equivalent annual rate from a monthly rate is\n1 + EAR = (1 + MR)^12\nor\nEAR = ((1 + MR)^12) - 1\nwhere EAR is the effective annual rate and MR is the monthly rate and both numbers are expressed as absolute decimals (rather than as percentages).\nPrepare the calculator\n\nIn order to work through the following example, you should prepare the calculator by first tapping the CLR key and then tap\n0 . 2 1 3 0 7 9 9 1 Enter +\nAn Example\n\nSuppose that you have calculated a monthly interest rate of 0.21307991% using your basic financial calculator. The first step in converting this to an effective annual percentage rate is to convert the monthly rate from a percentage to an absolute rate. Divide the percentage rate by 100 to convert to an absolute (fractional) rate. Tap\n1 0 0 /\nThe number that is displayed on the screen should now be 0.0021307991. The next step is to add one and then raise the result to the 12th power. Tap\n1 + 1 2 y^x\nThe number is now 1.0258714. Subtract one to get the absolute (fractional) rate, and then multiply by 100 to convert the fractional rate to a percentage. Tap\n1 - 1 0 0 X\nThe answer is 2.58714%.

This is my source: http://faculty.elgin.edu/mpelczarski/cis207/loanformulajava.htm.\nM = p * (a-1) / (1-a^-n)\n\nwhere\n\nM = monthly payment\np = loan principal\nn = number of months\ni = interest rate (%)\na = amortization factor = (1 + ((i/100)/12))\n\nFor example, for a loan of $200K with fixed rate of 6.0% over 30 years:\n\na = (1 + ((5/100/12)) = 1.005\nM = 200000 * (1.005 - 1) / (1 - 1.005^-360)\n\nor\n\nM = $1199.10

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.

If it is a compounding interest, use this formula: $X x (1+interest rate)^Period. For your eg, if you are referring to 5% per annum, the answer is: $150 x (1.05)^(420/12) = $827.4, i.e. 5.516 times your original capital.
