Income Flashcards
Annuity
payments of predictable amounts paid at constant intervals. -1 in payment solve for FV
Ordinary annuity
payments at the end of the period
Annuity in advance
payments at the beginning of the period
What is the formula for change
End # / Begin # -1
How do you calculate the annual rate of change?
white keys, solve for i
If a value completely declines or erodes in value what is the change on a percentage basis
-100% or -1
How do you calculate a compounded interest rate? Is this direct cap or yield cap?
1-(1+(Y/n)^n or with the white keys solve for i
Yield cap
Sinking fund factor
amount per period to get a specific end value +1 in FV solve for PMT
Present worth factor
what is money in the future worth today? +1 in FV solve for PMT
Present worth of an annuity factor
PV of an income stream +1 in PMT solve for PV
Amortization factor
Loan constant +1 in PV solve for PMT
other terms for the mortgage constant
Annual Amortization factor, Rm, Amortization factor, loan constant, rate to mortgage, mortgage cap rate
what is the formula for the loan constant
Rm = Ym - change Vm*SFF
For a fully amortizing loan does the loan constant remain constant over time?
No. It declines every time a payment is made so the Rm goes up after each payment
What’s the difference between the Ym and the Rm
The Ym is the yield to the mortgage - this is the interest with no points. The Rm is the rate to the mortgage - this is the loan constant.
Im/Vm = Rm Im/Rm =Vm
What are four ways to describe the Ym
Yield to the mortgage, interest rate with no points, lender’s return on, borrowers cost of capital as a %, interest portion of loan payment (what the bank makes on the loan)
What are two ways to describe the Rm
lenders rate of return on & of, principal & interest (what you pay the bank)
Loan constant - how is it computed and expressed?
Rm the amount needed to amortize $. computed monthly, expressed annually
SFF- how is it computed and expressed?
SFF always calculated annually at the yield rate over the holding period. It is used to spread value change over the holding period
How do you calculate a loan balance
calculate payment, change n to reflect the payments made, calculate FV. OR change N to relfect payments to go and calculate PV.
