    Finding Principal, please help!

    How much principal is repaid in the 74th payment interval on a $142300 25-year mortgage? The mortgage is amortized over 25 years and the payments are monthly. The interest rate is 7.44% compounded monthly.

    Solve for the monthly payment R.
    Then calculate directly with R(1.0062)^(-(300-74+1))
    Or you could torture yourself (while verifying) with the so called retrospective method.
    You really ought to read your book.
