1. What Is Mortgage Prime Rate?

The mortgage prime rate is the interest rate that commercial banks charge their most creditworthy customers. It serves as a benchmark for various lending products, including mortgages, personal loans, and credit cards.

2. How Is Prime Rate Calculated?

The prime rate is calculated using the formula:

\[ \text{Prime Rate} = \text{Benchmark Rate} + \text{Spread} \]

Where:

\( \text{Benchmark Rate} \) — The base interest rate set by central banks or market indices
\( \text{Spread} \) — The additional percentage points banks add to cover costs and profit

Explanation: The benchmark rate represents the fundamental cost of borrowing, while the spread accounts for the bank's operational costs, risk premium, and profit margin.

3. Importance Of Prime Rate Calculation

Details: Accurate prime rate calculation is crucial for determining mortgage affordability, comparing loan offers across different lenders, and understanding the true cost of borrowing for home purchases.

4. Using The Calculator

Tips: Enter the benchmark rate and spread as percentages. Both values must be non-negative numbers. The calculator will compute the resulting prime rate.
