Definition
A rate floor is the mirror image of a cap: it sets the lowest your variable rate can go. Many facilities include a zero-floor on the reference rate, so if the benchmark turns negative you still pay the margin. Floors protect the lender’s minimum return.
In plain terms
It stops your rate falling as far as the benchmark might. In a falling-rate environment, the floor is where your saving stops.
Why it matters for your company
Check whether your facility has a floor — it caps how much a rate cut will help you. See rate cap and collar.
