Part and Part Mortgage Calculator
A part and part (split repayment) mortgage puts some of the loan on repayment and the rest on interest-only. Tell us your monthly budget and this calculator works out how much could sit on each part, so the two payments add up to what you can afford.
The interest-only part is not paid off by your monthly payments. You would still owe it when the term ends and would need a plan to repay it.

Illustrative only. Interest-only borrowing needs a way to repay the loan at the end of the term, such as savings, investments or selling the property, and lenders will ask what yours is. Not every lender offers part and part, and lending is subject to affordability and criteria. This is not personal advice.

Frequently Asked Questions
It splits your borrowing in two. One part is on repayment, so you pay off the capital and the interest. The other is on interest-only, so you pay just the interest and still owe that part at the end of the term.
It takes your monthly budget and finds the amount on repayment that, together with the interest on the rest, uses that budget exactly. A longer term or a lower rate puts more of the loan on repayment.
It is still owed in full. You would need to repay it from another source, such as savings, investments or selling the property. Lenders will ask for your plan before they lend.
If your budget already covers a full repayment mortgage over the term you choose, nothing needs to be interest-only. The calculator then shows what is left over each month.
Not every lender offers part and part, and those that do apply their own affordability checks, loan size limits and repayment plan rules. An adviser can tell you which lenders might consider your case.
