Understanding Loan Types and How They Work
Amortized Loans: Fixed Payments Over Time
Amortized loans are the most common type of consumer loans. These loans require regular, fixed payments that cover both principal and interest until the loan is fully paid off. Common examples include:
- Home mortgages
- Auto loans
- Student loans
- Personal loans
In daily conversations, “loan” typically refers to this type. These loans are ideal for borrowers who prefer predictable payments and a clear payoff timeline.

Deferred Payment Loans: Lump-Sum Payment at Maturity
Deferred payment loans are often used in commercial or short-term lending. Instead of monthly payments, the full principal and interest are paid as one lump sum when the loan matures.
Balloon loans are a variant, sometimes requiring small periodic payments, but the main repayment still occurs at the end. This type of loan is suitable for borrowers expecting a large future cash inflow.
Bonds: Single Payment Plus Interest or Discounted Sale
Bonds function differently from traditional loans. A borrower issues a bond and agrees to repay the face value—also called par value—at maturity. The value of a bond can change with market conditions, but the repayment amount at maturity remains fixed.
There are two main types:
- Coupon Bonds: Pay interest periodically (usually semi-annually) based on a fixed percentage of the bond’s face value.
- Zero-Coupon Bonds: Sold at a discount, they do not pay periodic interest. Instead, the investor receives the full face value at maturity.
Our calculator supports zero-coupon bond computations for those looking to understand total future repayment.
Key Loan Concepts Every Borrower Should Know
Interest Rate
Interest is the cost of borrowing money. It’s typically shown as an APR (Annual Percentage Rate), which includes both the base interest and any fees. This differs from APY (Annual Percentage Yield), which is used for savings accounts and includes compounding interest.
Use our Interest Calculator to estimate how much you’ll pay in interest or visit the APR Calculator for more detailed analysis.
Compounding Frequency
Interest that compounds more frequently results in higher total repayment. Most loans use monthly compounding, but it’s helpful to explore how different compounding schedules impact your loan using our Compound Interest Calculator.
Loan Term
The loan term is the length of time you have to repay the loan. A longer term typically means lower monthly payments, but higher total interest paid over time. Choosing the right loan term is about balancing monthly affordability with overall cost.
Types of Consumer Loans
Consumer loans are classified into two major categories: secured and unsecured.
Secured Loans
These loans require collateral—something valuable you pledge to the lender. If you default, the lender can seize this asset.
Common secured loans include:
- Mortgages (home used as collateral)
- Auto loans (car used as collateral)
Since the risk to the lender is lower, secured loans often offer lower interest rates and higher approval odds.
Unsecured Loans
Unsecured loans don’t require collateral. Approval is based on the borrower’s creditworthiness, evaluated through the Five C’s of Credit:
- Character – Credit history and income reliability
- Capacity – Ability to repay based on debt-to-income ratio
- Capital – Other assets or savings that support repayment
- Collateral – Not applicable here but important in secured loans
- Conditions – Purpose of the loan and current economic climate
Because unsecured loans are riskier for lenders, they often come with higher interest rates, lower limits, and may require a co-signer.
Examples of unsecured loans:
- Credit cards
- Personal loans
Student loans
