What this part and part mortgage calculator does

This page models two mortgage parts together and shows one combined result set. Enter values for Mortgage 1 and Mortgage 2, then review one merged output for monthly repayment, total paid, total interest, chart trend, and yearly schedule.

Use this when a property loan is split into two mortgage segments but you want to understand full combined cost in one place.

How combined totals are calculated

Each mortgage part is calculated independently using the same deterministic mortgage engine. The page then combines both parts into one merged monthly timeline.

Assumptions and limitations

Results use a fixed-rate, deterministic model for each mortgage part. Lender-specific fees, penalties, taxes, and insurance are not included unless manually modelled.

Actual mortgage outcomes can vary based on lender products, rate changes, and legal terms.

Frequently asked questions

Does this show combined repayment for both mortgage parts?

Yes. The main headline repayment and totals are combined values from Mortgage 1 and Mortgage 2.

Are charts and yearly schedule combined too?

Yes. The chart and yearly schedule are rendered from combined totals rather than side-by-side comparison cards.

Can Mortgage 1 and Mortgage 2 use different terms or rates?

Yes. Each part can use different amount, term, rate, and mortgage type. The result cards then show merged totals.
