1. What Is The Prime Rate?

The Prime Rate is the interest rate that commercial banks charge their most creditworthy customers, typically large corporations. It serves as a benchmark for many other interest rates in the economy, including rates for mortgages, small business loans, and credit cards.

2. How Does The Calculator Work?

The calculator uses the standard Prime Rate formula:

Where:

• \( Fed\ Funds\ Rate \) — The target federal funds rate set by the Federal Reserve
• \( Spread \) — Typically 3%, representing the bank's margin over the risk-free rate

Explanation: The Prime Rate is calculated by adding a standard spread (usually 3 percentage points) to the current federal funds rate. This spread covers the bank's operating costs and provides a profit margin.

3. Importance Of Prime Rate Calculation

Details: The Prime Rate is crucial because it influences borrowing costs throughout the economy. It affects everything from business loans and credit card rates to home equity lines of credit. Understanding how it's calculated helps businesses and consumers anticipate changes in borrowing costs.

4. Using The Calculator

Tips: Enter the current federal funds rate as a percentage. The spread is pre-set to 3% (the typical margin) but can be adjusted if needed. All values must be valid non-negative percentages.
