What this mortgage comparison calculator does
This mortgage comparison calculator lets you model two mortgage scenarios side by side using the same calculation engine, assumptions, and currency formatting.
Enter values for mortgage 1 and mortgage 2 to instantly compare:
- Monthly repayment
- Total paid over term
- Total interest paid
- Interest rate (annual)
- Remaining balance over time
- Yearly amortisation schedule for each mortgage
All calculations update instantly in your browser. No data is stored or transmitted.
This comparison page works globally. You can change country and currency in the header at any time.
How mortgage comparisons are calculated
Both scenarios are calculated independently using the same deterministic model, then compared KPI by KPI.
For repayment mortgages, each monthly payment includes interest and principal. For interest-only mortgages, monthly payments cover interest only and the principal remains outstanding at the end of term unless repaid separately.
Comparison deltas are shown directly in the KPI cards so you can see which scenario is more or less expensive over time.
What your comparison results show
- Primary KPI values for the active scenario
- Direct baseline comparison values
- Difference text in natural terms (for example, more per month or less over full term)
- Chart overlays for mortgage 1 vs mortgage 2
- Separate yearly schedules for both scenarios
You can adjust either scenario at any time to model different rates, terms, repayment types, or optional monthly payment constraints.
Assumptions and limitations
This mortgage comparison calculator provides deterministic estimates based on fixed inputs.
Results assume:
- A constant interest rate for each scenario over the full term
- Monthly compounding
- No refinancing or rate changes
- No lender-specific charges, penalties, or fees
- No taxes, insurance, escrow, or legal fees
Actual mortgage costs may vary depending on lender terms and local regulations.
Frequently asked questions
Can I compare repayment and interest-only side by side?
Yes. Each scenario can use its own mortgage type, term, interest rate, and monthly payment assumptions.
Do both scenarios use the same currency format?
Yes. Country and currency selection in the header is applied consistently to both scenarios and all outputs.
Does this page run on the same logic as the mortgage calculator?
Yes. Both pages use the same shared calculation logic and rendering pipeline so updates apply consistently.
