Comparing Fixed vs. Adjustable Rate Mortgages: Key Calculations

FAQ

What is the difference between fixed-rate and adjustable-rate mortgages?

A fixed-rate mortgage has a constant interest rate over the life of the loan, while an adjustable-rate mortgage has an interest rate that can change at specified times based on market conditions.

How do I calculate monthly payments for a fixed-rate mortgage?

You can calculate monthly payments for a fixed-rate mortgage using the formula: M = P[r(1 + r)^n] / [(1 + r)^n – 1], where M is the monthly payment, P is the loan amount, r is the monthly interest rate, and n is the number of payments.

What factors should I consider when choosing between fixed and adjustable rates?

Consider your long-term vs. short-term financial goals, your risk tolerance regarding interest rate fluctuations, and the current market conditions that may affect adjustable rates.

Can I save money with an adjustable-rate mortgage?

Yes, you may save money with an adjustable-rate mortgage initially due to lower starting interest rates, but be aware of potential rate increases in the future.

What are rate caps and floors in adjustable-rate mortgages?

Rate caps limit the amount by which your interest rate can increase during an adjustment period, while rate floors are the minimum interest rate that can apply to your loan.

How can I assess the total costs of each mortgage type over time?

To assess total costs, calculate the total interest paid over the life of the loan for both fixed and adjustable mortgages, factoring in any potential rate adjustments for adjustable loans.
