Evaluate shortening or extending your mortgage term
Why Term Change Matters
Refinancing to a different loan term is a powerful strategy for aligning mortgage payments with financial goals. Switching from a 30-year to a 15-year mortgage dramatically reduces total interest paid and builds equity faster, while extending a term can lower monthly payments for homeowners needing cash flow relief. This calculator models the trade-offs between different terms, helping agents advise clients on the option that best fits their stage of life and financial priorities.

Yes, 20-year terms are available from most lenders and offer a middle ground between 30-year and 15-year options. The payment is lower than a 15-year but the interest savings are still significant compared to a 30-year term. The calculator lets you compare any term lengths to find the sweet spot for your budget and timeline goals.
Extending your term lowers monthly payments but increases total interest paid. If the alternative is missing payments or depleting emergency savings, refinancing to a longer term can provide critical financial relief. However, explore other options first: payment forbearance, loan modification, or cutting expenses. The calculator helps you see exactly how a term extension affects both monthly payments and long-term costs.
