Technical name for Amortization with fixed principal amortization and increasing interests

Fixed amortization with increasing interest

A guy showed me an amortization schedule with fixed principal amortization each period but the interest part increases each period so payment due is larger in each consecutive period. What is the technical name for this kind of schedule?



Is it because the principal payments are lower than the mandatory amounts? If so, that would be capitalization of interest

Yea I ain’t clicking that.

its common (normal) in switzerland to have a fixed rate & this wonkey mortage…

interest is tax deductible, so I think it’s setup like this to have constant tax effects as the principle on the fixed loan reduces.

but I know zero about mortgages, so could be totally wrong.
