Principal and Interest
The principal is the original amount of money you borrow from a lender. It doesn't include interest or fees. As you make payments, a portion of each payment goes toward reducing the principal.
Interest is the cost of borrowing that principal. It's calculated as a percentage of the outstanding balance. Over the life of a loan, interest can add significantly to the total cost.
- Principal: The amount you borrow before interest and fees.
- Interest: The charge for borrowing, typically expressed as an annual percentage rate.
- On an amortizing loan, early payments go more to interest, while later payments go more to principal.
APR vs. Interest Rate
The interest rate is the basic percentage the lender charges for borrowing the principal. The Annual Percentage Rate (APR) includes the interest rate plus certain fees and costs, giving a more complete picture of what you'll pay over a year.
When comparing loans, APR is often a more accurate measure of total cost than the interest rate alone. However, APR may not include every fee, so it's important to read the loan estimate carefully.
- Interest Rate: The base cost of borrowing, expressed as a percentage of the loan amount.
- APR: Interest rate plus certain fees, such as origination fees and points, expressed as a yearly rate.
- Use APR when comparing loans with different fee structures.
Amortization and Amortization Schedule
Amortization is the process of paying off a loan over time through regular payments. Each payment is split between interest and principal. With a fixed-rate loan, the payment amount stays the same, but the proportion of interest to principal changes over time.
An amortization schedule is a table that shows each payment's breakdown—how much goes to interest and how much to principal—for the life of the loan. It also shows the remaining balance after each payment.
- Amortization: Paying down a loan with scheduled, regular payments.
- Amortization Schedule: A table listing each payment date, payment amount, interest portion, principal portion, and remaining balance.
- With a standard amortizing loan, you pay less interest over time as the principal balance decreases.
Loan Term and Loan Tenure
The loan term (or tenure) is the length of time you have to repay the loan. Common terms for mortgages are 15, 20, or 30 years; auto loans often range from 3 to 7 years; personal loans might be 1 to 5 years.
A longer loan term means lower monthly payments but more total interest over time. A shorter term means higher monthly payments but less interest paid overall.
- Loan Term: The time you agree to repay the loan in full.
- Example: A 30-year mortgage has 360 monthly payments.
- Choose a term based on your budget and how much interest you want to pay over time.
Prepayment and Payoff Amount
Prepayment is paying off part or all of your loan before the scheduled due date. Some loans have prepayment penalties, so check your loan agreement before making extra payments.
The payoff amount is the total needed to completely repay the loan as of a specific date. It includes the remaining principal, accrued interest, and any fees or penalties. Because interest accrues daily, the payoff amount changes until the loan is closed.
- Prepayment: Paying more than the required amount or paying off early.
- Payoff Amount: The exact sum to fully satisfy the loan on a given date.
- Request a payoff statement from your lender to get the current figure.
Frequently asked questions
What is the difference between APR and the interest rate?
The interest rate is the percentage you pay on the principal. APR includes the interest rate plus certain fees, so it gives a more complete view of the annual cost. When comparing loans, APR is often the better figure to use.
How does amortization affect my monthly payment?
With amortization, your monthly payment stays the same (for a fixed-rate loan), but the split between interest and principal changes. Early on, most of the payment goes to interest; later, more goes to principal. An amortization schedule shows this breakdown.
What is a loan term and how does it affect my payments?
The loan term is how long you have to repay the loan. A longer term lowers your monthly payment but increases total interest. A shorter term raises monthly payments but saves you interest overall.
What is the payoff amount on a loan?
The payoff amount is the total needed to completely repay the loan on a specific date. It includes the remaining principal, accrued interest, and any fees or penalties. Because interest accrues daily, the amount changes over time.
Can I pay off my loan early?
Yes, many loans allow prepayment without penalty, but some charge a prepayment penalty. Review your loan agreement carefully before making extra payments or paying off the loan early.
