FAQ
Does 0% interest work here?
Yes. At 0% interest, both methods reduce to evenly splitting the principal across the term with no interest added.
What is the difference between amortized and equal principal?
Amortized repayment keeps the payment amount mostly stable, while equal principal keeps the principal portion fixed and makes the payment decline over time.
What does the repayment schedule show?
It shows how much of each payment goes to principal and interest, plus the remaining balance after every month, which makes side-by-side method comparison easier.
