An amortised loan would involve more frequent payments (e.g., monthly) that include both principal and interest, with the principal portion of each payment increasing over time. In this use case, the borrower pays the principal in large, lump-sum installments, in addition to paying the interest. The interest is recalculated upon the large repayments. Check out the demo video below to see how these repayments are created. {% @arcade/embed flowId="nNh9Pkak0MDJhKZrA4K0" url="" %}
