What’s the difference between a 15 and 30-year fixed-rate mortgage?

Both 15 and 30-year mortgage loans have a fixed interest rate, giving you the peace of mind that your monthly payment will always be the same. However, the amount of that monthly payment and the total interest you’ll pay can vary greatly between the two options.

The key difference is that with a 15-year mortgage you will typically enjoy lower interest rates and with a 30-year mortgage you'll benefit from lower monthly payments.

Knowing what your monthly payment may be with a 15 or 30-year mortgage can help you decide which loan you’d be more comfortable with. Use the mortgage calculator above to see which option offers more cost savings for you.
