Which term describes the index rate prevailing at origination, plus the margin that will apply after the expiration of an introductory interest rate?

• A. Note Rate
• B. Annual Percentage Rate
• C. Fully Indexed Rate
• D. Teaser Rate

Answer: (C)

The fully indexed rate is the rate that will apply after the introductory period ends, calculated by taking the index rate in effect at origination and adding the loan’s margin. This combination sets the baseline for future adjustments—the rate used if the introductory period expires immediately and the loan follows its typical adjustment schedule. Think of it as the true underlying rate builders use to determine future payments: the index value at closing plus the margin. It’s not the teaser rate, which is just the temporary low starting rate, and it isn’t the note rate or the APR, which are different concepts used for disclosure and terms. For example, if the index at origination is 3.0% and the margin is 2.75%, the fully indexed rate would be 5.75%, subject to any caps or adjustments defined in the loan.
