Definition

An interest rate buffer is the margin between what you can afford and what your current payments are, deliberately kept so a rate rise does not break your cover. Lenders build one into their affordability tests; prudent borrowers build their own.

In plain terms

It is the shock absorber on your borrowing — the room to keep paying comfortably even if rates climb.

Why it matters for your company

Borrow with a buffer, not to the limit, so a rise is an inconvenience not a crisis. See how to stress-test a loan against rate rises.
