Understanding Loan Structures

Loans can be structured in different ways, affecting how and when you pay them back. Our calculator can model three common types:

How It Works

Select Loan Type: Choose between "Amortized Loan," "Deferred Payment," or "Bond" using the tabs at the top of the calculator.
Enter Your Details: Input the required information, such as the loan amount, interest rate, and term. The results will update instantly.
Review Your Payments: The summary section will show you your estimated monthly payments or the final lump-sum amount, along with the total interest you will pay.

Amortized Loan

This is the most common type of consumer loan, including mortgages and auto loans. You make fixed, periodic payments that cover both principal and interest. Over time, the portion of your payment going toward principal increases as the interest portion decreases. For tracking your monthly budget, including loan payments, use our ClarityBudgets tool.

Deferred Payment Loan

Common for short-term or commercial loans, this structure requires a single lump-sum payment of both principal and all accrued interest at the end of the loan term. No periodic payments are made.

Bond (Zero-Coupon)

Bonds are a form of loan where you, the borrower, receive a discounted amount upfront and agree to pay back a predetermined lump sum (the face value) at maturity. Our calculator handles zero-coupon bonds, which do not pay periodic interest. The "interest" is the difference between the discounted price and the face value. This can be compared against other opportunities in our Investment Growth Calculator.
