What is an Interest Rate?
An interest rate is the percentage of a sum of money that is charged for its use. It represents the cost of borrowing money or the reward for lending it. Interest rates can apply to various types of financial products, including mortgages, credit cards, and savings accounts.
Rate of Return
The rate of return (RoR) is another critical application of interest rates. It represents the gain or loss on an investment over a specific period, expressed as a percentage of the investment’s initial cost. Understanding the RoR helps investors make smarter financial decisions.
Mortgage Loans: An Example
Consider a scenario where you take out a $250,000 mortgage loan at an interest rate of 6% with 4 discount points. Here’s how the numbers stack up:
- Contract Interest Rate: 6% - This rate determines your monthly payment amount.
- Discount Points: 4 points, which are fees paid upfront to reduce the loan’s interest rate.
- Effective Interest Rate: 6.39% - This incorporates the effects of the discount points and is the actual rate of return to the lender if the loan runs to maturity.
By understanding these elements, you can better comprehend how interest impacts your financial commitments.
