Frequently Asked Questions
What is a repayment mortgage?
You pay both interest and principal each month. By the end of the term, the loan is fully paid off.
What is an interest-only mortgage?
You pay only the interest each month. You must repay the full principal at the end of the term, usually via savings, investments, or selling the property.
How is the monthly payment calculated?
Repayment mortgages use standard amortization. Interest-only payments equal the loan balance multiplied by the monthly interest rate.
Does this include fees?
No. This calculator shows principal and interest only. Arrangement fees, valuation fees, and other charges are not included.
