12 C.F.R. Appendix K to Part 1026
(3) Definitions of time intervals.
(4) Unit-period.
(i) In all transactions other than single-advance, single-payment transactions, the unit-period shall be that common period, not to exceed one year, that occurs most frequently in the transaction, except that:
(5) Number of unit-periods between two given dates.
(6) Symbols. The symbols used to express the terms of a transaction in the equation set forth in paragraph (b)(8) of this appendix are defined as follows:
Aj = The amount of each periodic or lump-sum advance to the consumer under the reverse mortgage transaction.
i = Percentage rate of the total annual loan cost per unit-period, expressed as a decimal equivalent.
j = The number of unit-periods until the jth advance.
n = The number of unit-periods between consummation and repayment of the debt.
Pn = Min (Baln, Valn). This is the maximum amount that the creditor can be repaid at the specified loan term.
Baln = Loan balance at time of repayment, including all costs and fees incurred by the consumer (including any shared appreciation or shared equity amount) compounded to time n at the creditor's contract rate of interest.
Valn = Val0(1 + σ) y, where Val0 is the property value at consummation, σ is the assumed annual rate of appreciation for the dwelling, and y is the number of years in the assumed term. Valn must be reduced by the amount of any equity reserved for the consumer by agreement between the parties, or by 7 percent (or the amount or percentage specified in the credit agreement), if the amount required to be repaid is limited to the net proceeds of sale.
σ = The summation operator.
Symbols used in the examples shown in this appendix are defined as follows:

w = The number of unit-periods per year.
I = wi × 100 = the nominal total annual loan cost rate.
(7) General equation. The total annual loan cost rate for a reverse mortgage transaction must be determined by first solving the following formula, which sets forth the relationship between the advances to the consumer and the amount owed to the creditor under the terms of the reverse mortgage agreement for the loan cost rate per unit-period (the loan cost rate per unit-period is then multiplied by the number of unit-periods per year to obtain the total annual loan cost rate I; that is, I = wi):

(8) Solution of general equation by iteration process.
(i) The general equation in paragraph (b)(7) of this appendix, when applied to a simple transaction for a reverse mortgage loan of equal monthly advances of $350 each, and with a total amount owed of $14,313.08 at an assumed repayment period of two years, takes the special form:

Using the iteration procedures found in steps 1 through 4 of (b)(9)(i) of appendix J of this part, the total annual loan cost rate, correct to two decimals, is 48.53%.
(c) Examples of total annual loan cost rate computations—(1) Lump-sum advance at consummation.
Lump-sum advance to consumer at consummation: $30,000
Total of consumer's loan costs financed at consummation: $4,500
Contract interest rate: 11.60%
Estimated time of repayment (based on life expectancy of a consumer at age 78): 10 years
Appraised value of dwelling at consummation: $100,000
Assumed annual dwelling appreciation rate: 4%
P10 = Min (103,385.84, 137,662.72)

i = .1317069438
Total annual loan cost rate (100(.1317069438 × 1)) = 13.17%
(2) Monthly advance beginning at consummation.
Monthly advance to consumer, beginning at consummation: $492.51
Total of consumer's loan costs financed at consummation: $4,500
Contract interest rate: 9.00%
Estimated time of repayment (based on life expectancy of a consumer at age 78): 10 years
Appraised value of dwelling at consummation: $100,000
Assumed annual dwelling appreciation rate: 8%

Total annual loan cost rate (100(.009061140 × 12)) = 10.87%
(3) Lump sum advance at consummation and monthly advances thereafter.
Lump sum advance to consumer at consummation: $10,000
Monthly advance to consumer, beginning at consummation: $725
Total of consumer's loan costs financed at consummation: $4,500
Contract rate of interest: 8.5%
Estimated time of repayment (based on life expectancy of a consumer at age 75): 12 years
Appraised value of dwelling at consummation: $100,000
Assumed annual dwelling appreciation rate: 8%

Total annual loan cost rate (100(.007708844 × 12)) = 9.25%

The cost of any reverse mortgage loan depends on how long you keep the loan and how much your house appreciates in value. Generally, the longer you keep a reverse mortgage, the lower the total annual loan cost rate will be.
This table shows the estimated cost of your reverse mortgage loan, expressed as an annual rate. It illustrates the cost for three [four] loan terms: 2 years, [half of life expectancy for someone your age,] that life expectancy, and 1.4 times that life expectancy. The table also shows the cost of the loan, assuming the value of your home appreciates at three different rates: 0%, 4% and 8%.
The total annual loan cost rates in this table are based on the total charges associated with this loan. These charges typically include principal, interest, closing costs, mortgage insurance premiums, annuity costs, and servicing costs (but not costs when you sell the home).
The rates in this table are estimates. Your actual cost may differ if, for example, the amount of your loan advances varies or the interest rate on your mortgage changes.
