Payment Calculations for Mortgage-Backed Securities

Product Overview

Payment Calculations for

Single Family Mortgage-Backed Securities

The formulas listed below illustrate calculations of the interest payments and principal payments for

Freddie Mac¡¯s Single Family mortgage-backed securities products.

Examples of how a July payment is calculated are depicted below for 45-day, 55-day and 75-day securities.

For 55-day securities, the ¡°Payment Date¡± is the 25th day of each month, or if the 25th day is not a business day,

the next business day applies.

For 45-day and 75-day securities, the ¡°Payment Date¡± is the 15th day of each month, or if the 15th day is not a

business day, the next business day applies.

July Payment Example

55-DAY SECURITIES

Interest Payment = (PAR) (June Factor) (Rate/12)

Principal Payment = (June Factor ¨C July Factor) (PAR)

45-DAY SECURITIES

Interest Payment = (PAR) (June Factor) (Rate/12)

Principal Payment = (June Factor ¨C July Factor) (PAR)

75-DAY SECURITIES

Interest Payment = (PAR) (May Factor) (Rate/12)

Principal Payment = (May Factor ¨C June Factor) (PAR)

DEFINITIONS: PAR - Original Security Balance at Issuance; Rate - Security Coupon Interest Rate; Factor - Eight digit decimal

which represents the percentage of the original balance of the pool or tranche that is outstanding as of a given date
