12 CFR Appendix K to Part 1026, Total Annual Loan Cost Rate Computations for Reverse Mortgage Transactions
(a)Introduction. Creditors are required to disclose a series of total annual loan cost rates for each reverse mortgage transaction. This appendix contains the equations creditors must use in computing the total annual loan cost rate for various transactions, as well as instructions, explanations, and examples for various transactions. This appendix is modeled after appendix J of this part (Annual Percentage Rates Computations for Closedend Credit Transactions); creditors should consult appendix J of this part for additional guidance in using the formulas for reverse mortgages.
(b)Instructions and equations for the total annual loan cost rate 
(1)General rule. The total annual loan cost rate shall be the nominal total annual loan cost rate determined by multiplying the unitperiod rate by the number of unitperiods in a year.
(2)Term of the transaction. For purposes of total annual loan cost disclosures, the term of a reverse mortgage transaction is assumed to begin on the first of the month in which consummation is expected to occur. If a loan cost or any portion of a loan cost is initially incurred beginning on a date later than consummation, the term of the transaction is assumed to begin on the first of the month in which that loan cost is incurred. For purposes of total annual loan cost disclosures, the term ends on each of the assumed loan periods specified in § 1026.33(c)(6).
(3)Definitions of time intervals.
(i) A period is the interval of time between advances.
(ii) A common period is any period that occurs more than once in a transaction.
(iii) A standard interval of time is a day, week, semimonth, month, or a multiple of a week or a month up to, but not exceeding, 1 year.
(iv) All months shall be considered to have an equal number of days.
(4)Unitperiod.
(i) In all transactions other than singleadvance, singlepayment transactions, the unitperiod shall be that common period, not to exceed one year, that occurs most frequently in the transaction, except that:
(A) If two or more common periods occur with equal frequency, the smaller of such common periods shall be the unitperiod; or
(B) If there is no common period in the transaction, the unitperiod shall be that period which is the average of all periods rounded to the nearest whole standard interval of time. If the average is equally near two standard intervals of time, the lower shall be the unitperiod.
(ii) In a singleadvance, singlepayment transaction, the unitperiod shall be the term of the transaction, but shall not exceed one year.
(5)Number of unitperiods between two given dates.
(i) The number of days between two dates shall be the number of 24hour intervals between any point in time on the first date to the same point in time on the second date.
(ii) If the unitperiod is a month, the number of full unitperiods between two dates shall be the number of months. If the unitperiod is a month, the number of unitperiods per year shall be 12.
(iii) If the unitperiod is a semimonth or a multiple of a month not exceeding 11 months, the number of days between two dates shall be 30 times the number of full months. The number of full unitperiods shall be determined by dividing the number of days by 15 in the case of a semimonthly unitperiod or by the appropriate multiple of 30 in the case of a multimonthly unitperiod. If the unitperiod is a semimonth, the number of unitperiods per year shall be 24. If the number of unitperiods is a multiple of a month, the number of unitperiods per year shall be 12 divided by the number of months per unitperiod.
(iv) If the unitperiod is a day, a week, or a multiple of a week, the number of full unitperiods shall be determined by dividing the number of days between the two given dates by the number of days per unitperiod. If the unitperiod is a day, the number of unitperiods per year shall be 365. If the unitperiod is a week or a multiple of a week, the number of unitperiods per year shall be 52 divided by the number of weeks per unitperiod.
(v) If the unitperiod is a year, the number of full unitperiods between two dates shall be the number of full years (each equal to 12 months).
(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:
Symbols used in the examples shown in this appendix are defined as follows:
(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 unitperiod (the loan cost rate per unitperiod is then multiplied by the number of unitperiods 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:
(ii) In using these iteration procedures, it is expected that calculators or computers will be programmed to carry all available decimals throughout the calculation and that enough iterations will be performed to make virtually certain that the total annual loan cost rate obtained, when rounded to two decimals, is correct. Total annual loan cost rates in the examples below were obtained by using a 10digit programmable calculator and the iteration procedure described in appendix J of this part.
(9)Assumption for discretionary cash advances. If the consumer controls the timing of advances made after consummation (such as in a credit line arrangement), the creditor must use the general formula in paragraph (b)(7) of this appendix. The total annual loan cost rate shall be based on the assumption that 50 percent of the principal loan amount is advanced at closing, or in the case of an openend transaction, at the time the consumer becomes obligated under the plan. Creditors shall assume the advances are made at the interest rate then in effect and that no further advances are made to, or repayments made by, the consumer during the term of the transaction or plan.
(10)Assumption for variablerate reverse mortgage transactions. If the interest rate for a reverse mortgage transaction may increase during the loan term and the amount or timing is not known at consummation, creditors shall base the disclosures on the initial interest rate in effect at the time the disclosures are provided.
(11)Assumption for closing costs. In calculating the total annual loan cost rate, creditors shall assume all closing and other consumer costs are financed by the creditor.
(c)Examples of total annual loan cost rate computations 
(1)Lumpsum advance at consummation.
(2)Monthly advance beginning at consummation.
(3)Lump sum advance at consummation and monthly advances thereafter.

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.
