This is a calculation and planning tool for estimating mortgage repayments with advanced rate schedules.
No loans, no applications, no brokerage.
The app does not provide financial services, does not connect you to lenders, and does not support any payments or transactions.
Model realistic scenarios such as:
・0.5% for the first 10 years → 1.2% from year 11
・step-up rates, or potential increases in variable rates
Key Features
1. Flexible rate schedules
Define interest rates by period to simulate step-up plans or future rate changes.
2. Save & load scenarios
Store multiple scenarios on your device and revisit them anytime.
3. Export & share
Export results (e.g., text/PDF) to share with your spouse or keep for your personal records.
4. Minimal, distraction-free design
A calm charcoal-and-silver theme with no unnecessary distractions.
