    ISPMT vs IPMT (2002)

    I get the impression from the HELP menu that these are the same calculatons. Obviously, NOT as they return different results.
    What's the difference?

    Re: ISPMT vs IPMT (2002)

    They use different payment schemes.

    ISPMT assumes that the payments on the principal are constant over time, while the total payments (interest + payment on principal) vary over time.
    IPMT assumes that the total payments are constant over time, causing both payments on the principal and interest payments to vary, as in an annuity.
