INR = [PTpatient Ã· MNPT]ISI. The INR has no units (it is a ratio) and is determined to one decimal place. The first step of the INR calculation is to ânormalizeâ the PT by comparing it to the mean normal prothrombin time (MNPT), the geometric mean of the prothrombin times of the healthy adult population. In the second step, this ratio is raised to a power designated the ISI, or international sensitivity index.
NAR is calculated using a formula where the numerator is equal to interest received, plus late fees received, minus the 1% service fee paid. If Borrower payments on a Note are not received, the interest, and late fees received and service fee paid in that period will be zero.
