Fixed, Floating, and Variable Rates

Rate structures that distinguish locked pricing, benchmark-linked resets, broader variable terms, blended balances, and contract rates.

This branch explains how a contractual rate behaves after the initial quote. Fixed Interest Rate covers rates locked for a defined period, while Floating Interest Rate focuses on benchmark-plus-margin formulas.

Variable Interest Rate is the broader category for rates that can change under contract terms. Contract Interest Rate identifies the operative rate in the agreement, and Blended Rate combines rates across balances or tranches.

When reviewing any rate, verify the benchmark, margin, reset date, lookback, floor, cap, notice terms, balance method, day count, fees, and payment consequences. Similar labels do not guarantee identical legal or cash-flow treatment.

Blended Rate

Weighted-average interest rate across loans, balances, tranches, or funding sources, calculated using comparable amounts and rate conventions.

Contract Interest Rate

A contract interest rate is the operative rate stated directly or determined by a formula in a loan, bond, deposit, or other agreement.

Fixed Interest Rate

A fixed interest rate stays unchanged for an agreed period, providing rate certainty while fees, balances, or total payments may still vary.

Floating Interest Rate

A floating interest rate resets from a reference benchmark plus or minus a contractual spread, subject to timing rules, caps, and floors.

Variable Interest Rate

A variable interest rate can change under contractual rules tied to an index, an administered rate, or another stated adjustment mechanism.
