Julie Miller has $1,000 to invest for 2 Years at an annual interest rate of 12%. - Julie Miller has $1,000 to invest for 2 Years at an annual interest rate of 12%.
- Annual FV2 = 1,000(1 + [0.12/1])(1)(2) = 1,254.40
- Semi FV2 = 1,000(1 + [0.12/2])(2)(2) = 1,262.48
Qrtly FV2 = 1,000(1 + [0.12/4])(4)(2) = 1,266.77 - Qrtly FV2 = 1,000(1 + [0.12/4])(4)(2) = 1,266.77
- Monthly FV2 = 1,000(1 + [0.12/12])(12)(2) = 1,269.73
- Daily FV2 = 1,000(1 + [0.12/365])(365)(2) = 1,271.20
- The result indicates that a $1,000 investment that earns a 12% annual rate compounded quarterly for 2 years will earn a future value of $1,266.77.

Julie Miller is borrowing $10,000 at a compound annual interest rate of 12%. Amortize the loan if annual payments are made for 5 years. - Julie Miller is borrowing $10,000 at a compound annual interest rate of 12%. Amortize the loan if annual payments are made for 5 years.
- Step 1: Payment
- PV0 = R (PVIFA i%,n)
- $10,000 = R (PVIFA 12%,5)
- $10,000 = R (3.605)
- R = $10,000 / 3.605 = $2,774
