Short Answer
Loan terms affect the cost of credit mainly through the loan’s repayment period, interest rate, fees, and payment schedule. A longer loan term usually lowers the monthly payment but increases the total interest paid because you borrow the money for a longer period. A shorter term usually means higher monthly payments but less interest and a lower total borrowing cost, assuming other terms are similar.
What Are Loan Terms?
Loan terms are the conditions that determine how you borrow and repay money. They can include:
- Loan amount
- Interest rate
- APR
- Repayment period
- Monthly payment
- Fees and charges
- Payment frequency
- Prepayment conditions
These terms determine both your regular payment and the total amount you may pay over the life of the loan.
The cost of credit can include interest and certain fees charged for obtaining the loan. APR provides a broader way to compare borrowing costs because it can include the interest rate and certain additional charges.
How Does the Loan Term Affect Total Cost?
The length of a loan is one of the most important factors affecting its total cost.
A longer repayment period spreads the balance over more payments. This generally makes each monthly payment smaller, but interest continues to accrue for a longer period.
A shorter repayment period generally results in larger monthly payments, but you repay the balance sooner and usually pay less interest overall.
For example, the CFPB gives an example of a $20,000 auto loan at 4.75% interest:
| Loan Term | Monthly Payment | Total Interest |
|---|---|---|
| 36 months | $597 | $1,498 |
| 48 months | $458 | $1,999 |
| 60 months | $375 | $2,508 |
| 72 months | $320 | $3,024 |
This example shows the basic tradeoff: extending the loan lowers the monthly payment but increases the total interest paid.
Longer Loan Terms
A longer loan term can make borrowing easier to manage from a monthly-budget perspective.
For example, someone might choose a six-year auto loan instead of a three-year loan because the monthly payment is lower.
However, the lower payment does not mean the loan is cheaper.
If the interest rate and other terms remain the same, you generally pay interest over a longer period. This increases the total amount paid over the life of the loan.
The CFPB specifically advises borrowers to consider the total cost of a loan rather than looking only at the monthly payment.
Shorter Loan Terms
A shorter loan term usually means you have to make larger monthly payments.
The benefit is that you repay the debt faster. Because the outstanding balance is paid down sooner, you generally pay less interest over the life of the loan.
For example, a three-year loan may require a higher monthly payment than a six-year loan, but the borrower may pay substantially less interest overall.
For mortgages, the CFPB similarly explains that shorter terms typically have higher monthly payments but can result in a lower total loan cost.
How Interest Rates Affect the Cost of Credit
The interest rate is another major part of the cost of borrowing.
A higher interest rate generally means you pay more for borrowing money. A lower rate can reduce the interest cost, assuming other loan terms are comparable.
The loan term and interest rate can work together.
For example, consider two loans with the same amount borrowed and the same interest rate:
Loan A has a three-year term.
Loan B has a six-year term.
Loan B may have a lower monthly payment, but you generally pay interest for a longer period.
If the shorter-term loan also comes with a lower interest rate, the difference in total cost can be even greater.
APR and the Cost of Credit
When comparing loan offers, it is important to understand APR.
APR stands for Annual Percentage Rate. It is a broader measure of borrowing cost than the stated interest rate because it can include certain fees and charges associated with the loan.
For example, two loans might have similar interest rates but different fees.
Looking at the APR can help you compare the overall cost of those offers more effectively.
However, APR should not be viewed in isolation. The loan term, monthly payment, fees, and other conditions should also be considered.
Why Monthly Payment Can Be Misleading
One of the biggest mistakes borrowers can make is choosing a loan based only on the monthly payment.
Suppose you are offered two loans:
Loan A has a $400 monthly payment.
Loan B has a $300 monthly payment.
At first glance, Loan B may look better because you pay $100 less each month.
But if Loan B has a significantly longer repayment period, you could make many more payments and pay considerably more interest.
This is why the total amount paid over the entire loan term is important.
The CFPB recommends comparing the loan amount, APR, interest rate, loan length, and monthly payment rather than focusing only on the monthly payment.
Loan Fees Also Affect the Cost
Loan terms can include fees that increase the overall cost of borrowing.
Depending on the type of loan, these can include:
- Origination fees
- Documentation fees
- Application fees
- Late fees
- Points
- Other lender charges
For personal installment loans, the CFPB notes that fees and charges can add to the overall cost in addition to interest.
Therefore, a loan with a slightly lower interest rate is not necessarily cheaper if it has substantially higher fees.
Loan Term and Mortgages
Loan terms can have a particularly large effect on mortgage costs because mortgages are often repaid over many years.
For example, a 15-year mortgage generally has higher monthly payments than a 30-year mortgage, but the shorter term can result in significantly less interest paid over the life of the loan.
The CFPB also notes that choosing a shorter mortgage term generally means a higher monthly payment but can reduce the amount of interest paid over time.
Loan Term and Auto Loans
The same principle applies to auto loans.
A longer auto loan can reduce the monthly payment, but it generally increases the total interest paid.
Longer auto loans can also increase the risk that you owe more on the vehicle than it is worth, which is known as negative equity.
For this reason, borrowers should consider both affordability and the total cost before selecting a repayment period.
How to Choose a Loan Term
There is no single loan term that is right for everyone.
When choosing a term, consider:
- Whether the monthly payment fits comfortably within your budget
- How much total interest you will pay
- The loan’s APR
- Fees and other charges
- Whether the interest rate changes
- Whether you can make extra payments
- Whether there is a prepayment penalty
- The total amount you will repay
A shorter term can reduce interest costs, but the payment should still be affordable. Choosing a payment that is too high can create financial strain even if the loan costs less overall.
Example of Loan Terms Affecting Credit Cost
Imagine you borrow $25,000 at the same interest rate.
You have two choices:
Option A: 4-year term
Option B: 7-year term
Option A will generally have a higher monthly payment because you have fewer months to repay the $25,000.
Option B will generally have a lower monthly payment because the balance is spread across more months.
However, if the interest rate is the same, Option B generally results in more total interest because the balance remains outstanding for longer.
Therefore, the lower monthly payment does not necessarily mean the lower total cost.
How Can You Reduce the Cost of Credit?
You may be able to reduce your total borrowing cost by:
- Comparing multiple lenders
- Looking at APR rather than only the advertised interest rate
- Choosing a shorter term when the payment is affordable
- Negotiating applicable fees
- Making additional principal payments when permitted
- Avoiding unnecessary loan add-ons
- Checking for prepayment penalties
- Comparing the total amount you will repay
For some loans, making additional principal payments can shorten the repayment period and reduce future interest, although the effect depends on the loan’s terms and how payments are applied.
Loan Term vs. Interest Rate
Loan term and interest rate are different factors.
The loan term determines how long you have to repay the money.
The interest rate determines the rate at which interest is charged on the outstanding balance.
For example:
A shorter loan with a high interest rate may not always be cheaper than a longer loan with a substantially lower rate.
That is why borrowers should compare the complete loan offers rather than assuming that a shorter term automatically provides the lowest total cost.
APR, total interest, fees, and total repayment amount can provide a clearer picture.
Final Answer
Loan terms directly affect the cost of credit because they determine how long you make payments and how long interest can accumulate. A longer loan term usually gives you a lower monthly payment but can result in more total interest and a higher overall borrowing cost. A shorter term usually increases the monthly payment but can reduce the total interest paid. To compare loans properly, look at the interest rate, APR, loan term, fees, monthly payment, and total amount you will repay.
