Get a Lower Mortgage Payment with an interest-only mortgage payment.
Use this calculator to estimate the interest-only portion of a mortgage payment, then review how the payment may change after the interest-only period ends. This page is for planning and education only — a licensed loan officer can help you compare options based on your goals.
Estimate the interest-only payment
Adjust the loan details below to estimate the monthly interest-only payment and compare it with a fully amortized payment.
This estimate reflects principal and interest only. Property taxes, insurance, association dues, and other costs are not included.

Helpful notes
How an interest-only mortgage works
During the interest-only period, the scheduled payment is based on interest due rather than principal repayment. When that period ends, the loan typically converts to payments that repay principal and interest over the remaining term.
Pros and considerations to weigh carefully
An interest-only mortgage can fit some financial plans better than others. Reviewing both the initial payment and what happens later can help you decide which questions to ask next.
Potential advantages
This structure may create lower scheduled payments during the interest-only period, which can provide flexibility for borrowers who understand the tradeoffs and have a clear plan.
Payment change later
When principal repayment begins, the monthly payment may increase because the balance is repaid over fewer remaining years.
Principal balance
If only the scheduled interest-only payment is made, the principal balance generally does not decrease during that period.
Compare alternatives
It can help to compare this structure with fixed-rate, adjustable-rate, or other loan options to see which fits your timeline and risk comfort.
