What is the amount of each annuity payment if a 5 year ordinary annuity has a future value of 1000 with an interest rate of 8%?
FVA = $75 × (1.09)1 × 15- 1(0.09) = $2,202 .07 Financial Calculator: N = 15 I/Y = 9% PMT = -75 Hit FV key, or Compute Key then FV key FVADue = PMT [(1 + APRm )mn-1(APRm)](1 + APRm) Example: What is the future value of a 15 year, 9%, annuity due of $75/year? FVADue = $75 [(1.09)15- 1(0.09)] (1.09) = $2,400.25 Why is the FVDue larger than the future value of an ordinary annuity? Financial Calculator - may have an annuity due button. Example: Suppose you plan to purchase an automobile upon graduating from EWU. You plan to graduate in twelve months, and would like to have a down payment saved up by then. If you save $40 every month in an account that pays 7.5 percent compounded monthly, how big will your down payment be? FVA = $40 (1 + 0.07512) 12 × 1- 1(0.07512) = $496.85 Financial Calculator: I/Y = 0.625; PMT = 40; n = 12; Hit FV, or CPT and FV
Formula: Take the FVA formula: FVA = PMT (1 + APRm)mn-1( APRm) The present value of an annuity can be written as: FVA/(1 + APR/m)nm Therefore: PVA = FVA(1 + APR m)mn= [PMT (1 + APRm)mn -1(APRm)](1 + APRm)mn= PMT[ (1 + APRm)mn-1][1(1 + APRm)mn ]APRmPVA = PMT[1 - 1(1 + APRm)mn ]APRm - or -PVA = PMT[1(APR m) - 1APRm(1 + APRm)mn] PVA = $6,200 × [1 - 1(1.14)17] 0.14 = $39,511.73 Financial Calculator: N = 17; PMT = 6200; I/Y = 14; Hit PV, CPT then PV Example: You have just won the lottery and you can choose between receiving $200,000 a year for four years with payments beginning in one year, or you can receive $200,000 now and receive payments of $75,000 per year at the end of each year for the next ten years. If the appropriate discount rate is 13 percent, which should you choose? PVA = $200,000 × [1 - 1(1.13)4]0 .13 = $594,894.27PV = $200,000 + $75,000 × [1 - 1(1.13)10 ]0.13 = $606,968.26 Example: John pays a $137 car payment each month. He will have the loan paid off in 4 years if he continues to make his monthly payments. How much would John need to pay off his car loan today? Assume he has just made a payment and that
the interest rate he is charged on this loan is 8.3 percent compounded monthly? Financial Calculator Note: PVIFAr,n - always smaller than number of years the annuity runs. FVIFAr,n - larger than number of years assuming K > 0.PVADue = PMT[1(APRm) - 1APRm( 1 + APRm)mn](1 + APRm) Example: What is the present value of an 17 year annuity due which pays $6,200 per year if the interest rate is 14 percent? PVADue = $6,200[1(0.14) - 10.14(1.14) 17]×1.14=$45,043.37
PVP = PMT/(r/m) This is just a special case of the present value of an annuity formula where n = ∞: PVP = PVA = PMT [1(APRm)−1(APRm)(1+APRm)m∞ ] = PMT[1(APRm)−1( APRm)(1+APRm)∞] = PMT [1(APRm)−1(APRm)∞] = PMT [1(APRm)−1∞] = PMT[1 (APRm)−0] PVP = PMT(APRm)PV = $7,000[1 - 1(1.03)1,000,000 0.03] = $233,333.33 PV = 7000/0.03 = $233,333.33
A financial calculator can be used to solve this problem.
PVA = PMT[1(APRm)−1(APRm)(1+APRm) mn]PMT = PVA[1(APRm)−1(APRm )(1+APRm)mn]PMT = Principal[1(APR m)−1(APRm)(1+APRm)mn] Each Payment part interest, part principal Example: You borrow $12,000 to purchase a boat. The interest rate is 12½ percent compounded monthly, and the term of the loan is 3 years. What are the monthly payments? PMT = $12,000[1 - 1(1 + 0 .12512)360.12512] = $401.44
Let m = 10 billion; r = 1 (1 + 1/10,000,000,000)10,000,000,000 = 2.71828182832
FVn = PVer(n) ; PV = FVne-r(n) where: r = stated annual interest rate n = number of years e = 2.7183
The generalized effective periodic rate formula: Effective Rate = (1 + APRm)s−1 Where: APR = Annual Percentage Rate or
stated rate of interest
What is the present value of a $1000 ordinary annuity that earns 8% annually for an infinite number of periods?What is the present value of a $1,000 ordinary annuity that earns 8% annually for an infinite number of periods? $2.84 (You must calculate both the monthly deposit amount for an ordinary annuity ($286.13 = $1M/[FVIFA 1%,360]) and an annuity due ($283.29 = $1M/[(FVIFA 1%,360)(1.01)]).
What is the present value of a 5 year ordinary annuity with annual payments of 200?What is the present value of a 5-year ordinary annuity with annual payments of $200, evaluated at a 15 percent interest rate? Financial calculator solution: Inputs: N = 5; I = 15; PMT = -200; FV = 0. Output: PV = $670.43.
What is the formula to find the amount of ordinary annuity?The formula for determining the present value of an annuity is PV = dollar amount of an individual annuity payment multiplied by P = PMT * [1 – [ (1 / 1+r)^n] / r] where: P = Present value of your annuity stream. PMT = Dollar amount of each payment. r = Discount or interest rate.
How do you calculate the future value of an annuity?How to calculate the future value of an annuity? Define the periodic payment you will do (P), the return rate per period (r), and the number of periods you are going to contribute (n). Calculate: (1 + r)ⁿ minus one and divide by r. Multiply the result by P and you will have the future value of an annuity.
