Definition
An interest rate floor is a predetermined minimum interest rate agreed upon in a loan or derivative contract that protects lenders from falling rates. If interest rates drop below this set level, the lender receives at least the floor rate, ensuring a baseline yield on their investments.
Interest Rate Floor vs Interest Rate Ceiling Comparison
| Feature | Interest Rate Floor | Interest Rate Ceiling |

| Definition | Minimum interest rate in a loan or contract | Maximum interest rate in a loan or contract |
| Purpose | Protects lenders from low returns | Protects borrowers from high payments |
| Impact on Payments | Ensures a minimum payment regardless of market rates | Limits payment amounts even if market rates soar |
| Common Use | Adjustable-rate mortgages (ARMs) and derivatives | ARMs and floating rate loans |

Examples and Related Terms
- Adjustable-Rate Mortgage (ARM): A mortgage with an interest rate that may change periodically based on changes in a corresponding financial index.
- Derivatives: Financial contracts whose value depends on the price of an underlying asset, interest rates, or other variables.

1Payment = Principal × (Max(Floor rate, Current rate))
Where Current rate is the rate at which you would otherwise refinance if not for the floor.
