How this works
This calculator models constant principal amortisation — the standard for Swedish mortgages — where you pay a fixed principal slice plus interest on the declining balance each month.
Break-even is when cumulative monthly savings exceed the switching fee. Asset Worth tracks loans and models the same refinance logic inside the app.
