How to Use This Interest-Only Loan Calculator

Enter the loan amount, rate, the length of the interest-only period, and the total term. The calculator shows the interest-only payment, the payment after that period, and the total interest versus a standard loan.

Understanding Interest-Only Loan Loans

Interest-only loans keep early payments low by deferring principal. The trade-off is a higher payment later and more total interest, since the balance stays put during the interest-only window.

Tips for Getting the Best Interest-Only Loan Rate

Plan for the payment jump before it arrives. If you can, make voluntary principal payments during the interest-only period to soften the later increase and cut total interest.

Frequently Asked Questions

For an initial period you pay only the interest, so payments are lower but the balance does not fall. When that period ends, payments jump as you begin repaying principal over the remaining term.
