A variable-rate loan, also known as an adjustable-rate loan, is a type of loan where the interest rate can change over time based on market conditions. Unlike fixed-rate loans, which have a constant interest rate, the interest rate for variable-rate loans can fluctuate, often tied to a benchmark interest rate or index.
Historical Context
Variable-rate loans gained popularity in the late 20th century as financial markets became more dynamic and interest rates began to fluctuate more frequently. They offered a flexible alternative to the more traditional fixed-rate loans, appealing to borrowers who anticipated falling interest rates or who sought lower initial payments.

Detailed Explanations
How Variable-Rate Loans Work
Variable-rate loans have interest rates that are periodically adjusted based on a reference rate (e.g., LIBOR, Prime Rate) plus a margin determined by the lender. These adjustments can occur monthly, quarterly, annually, or at other specified intervals.
Mathematical Formula
The interest rate for a variable-rate loan is typically calculated as:
Example:
- Reference Rate: 3%
- Margin: 2%
- Interest Rate: 3% + 2% = 5%
