Frequently Asked Questions
How do I compare an ARM vs a fixed-rate mortgage? +
An ARM typically offers a lower initial rate for a set period (often 5, 7, or 10 years), then adjusts to market rates. The Mortgage and ARM vs Fixed Rate Calculator shows the breakeven reset rate, which is the future rate at which total interest costs become equal between the two options.
What is the mortgage breakeven rate between ARM and fixed? +
The breakeven rate is the ARM reset rate at which total interest paid equals the fixed-rate mortgage cost over the full loan term. If rates reset below this threshold, the ARM saves money. The Mortgage Calculator identifies this exact crossover point and visualizes it on an interactive chart.
Is a 7-year ARM worth it compared to a 30-year fixed? +
Many homebuyers find that if they plan to sell or refinance within the ARM's fixed period, the lower initial rate can result in meaningful savings. One important consideration is what happens if plans change. This calculator models both scenarios so you can see the potential cost difference at various future rate levels.
How does applying extra principal payments affect an ARM mortgage? +
When ARM payments are lower than a comparable fixed-rate payment, directing that difference toward extra principal builds equity faster and reduces the remaining balance before the rate resets. This calculator includes a toggle to model this strategy, showing the equity advantage and interest savings over time.
How much total interest will I pay over the life of a 30-year mortgage? +
On a typical 30-year mortgage, total interest paid often exceeds the original loan amount. For example, a $500,000 loan at 7% results in roughly $698,000 in total interest. The amortization schedule in this calculator breaks down every payment so you can see how principal and interest shift month by month.
