Does anyone have Loan Amortization Schedule with Extra Payments

I am looking for a loan amortization schedule with extra payment options to analyze loans. Thanks

@Cerbat my knowledge in this regard are zero. There are some exercises on the German website of LibreOffice. In the Calc exercises under position

“7. Amortization calculation for investment decisions”.

Maybe you’ll take a look at it and you may be able to customize it for your needs.

I wish you success!
