How Does the Length of a Loan Affect Its Total Cost?

When you compare loans, it can be tempting to focus on the repayment amount alone. A lower weekly or fortnightly repayment may look easier to manage, but that does not necessarily mean the loan will cost less overall.

The relationship between a loan term and total cost is usually straightforward. A longer term may reduce each scheduled repayment, but it can increase the amount of interest you pay. A shorter term can reduce the total interest, although your regular repayments will generally be higher.

Moneysmart explains that shorter loan terms can mean less interest overall, while longer terms may lower repayments but increase the total cost.

Understanding this trade-off can help you compare loans more carefully and choose a repayment schedule that is manageable without keeping the debt in place unnecessarily.

What Is a Loan Term?

A loan term is the period you agree to repay the money you borrow.

Depending on the credit product, it may be expressed in:

• Days.
• Weeks.
• Months.
• Years.

For example, a short-term personal loan may run for several weeks or months, while a car loan or home loan may continue for several years.

The term can affect:

• How many repayments you make.
• The amount of each scheduled repayment.
• How long interest may be charged.
• Whether recurring fees apply for longer.
• The total amount you repay by the end of the contract.

Your loan term is different from your repayment frequency.

For example, your term might be six months while you make repayments weekly or fortnightly.

What Does Total Loan Cost Mean?

There are two related figures worth understanding when you compare loans.

The cost of borrowing generally refers to the interest, establishment fees and other charges you pay for access to credit.

The total amount repaid generally includes:

• The original amount borrowed, known as the principal.
• Interest.
• Establishment or application fees.
• Regular account fees, when applicable.
• Late-payment, default or other conditional fees, when applicable.

Always check what is included when you see the phrase “total cost”.

One figure may include the original amount you borrowed, while another may refer only to the interest and fees paid above the principal.

How Are Loan Term and Total Cost Connected?

Assuming the amount borrowed, interest rate and fee structure stay the same, the differences will generally look like this:

This does not mean choosing the shortest available term is automatically the right decision.

Your repayments still need to fit within your budget. A shorter term that leaves you struggling to pay for rent, groceries, transport or other essential expenses may create more financial pressure.

Before agreeing to a loan, check that you are likely to have enough money available when repayments are due and understand any fees that could apply if a repayment is missed.

Why Does a Longer Loan Term Usually Cost More?

Interest May Be Charged for Longer

Interest is the amount charged for providing credit.

On many loans, extending the repayment period gives interest more time to accumulate. Even when the interest rate stays the same, paying down the balance more slowly can increase the total amount of interest charged.

Your individual repayment may be smaller, but you may make more repayments before the debt is cleared.

Some Fees May Apply Repeatedly

The effect of a longer term also depends on the loan’s fee structure.

A one-off establishment fee may remain the same regardless of the term. In contrast, an account-keeping or administration fee charged each month can add to the cost when a loan continues for longer.

When comparing loan terms, check:

• Which fees apply once.
• Which fees apply regularly.
• Whether missed-payment or default fees may apply.
• Whether there is an early repayment fee.
• Whether changing your repayment arrangements attracts a fee.

Looking at interest alone may not give you a complete picture of what a loan will cost.

The Balance May Reduce More Slowly

Your repayments generally cover interest, applicable fees and part of the principal.

With a longer term and smaller repayments, the principal may reduce more gradually.

Depending on how interest is calculated under your contract, that can leave a larger balance outstanding for longer.

Can a Shorter Loan Term Save You Money?

A shorter term can reduce your overall borrowing cost when it allows you to repay the principal sooner and reduces the period over which interest is charged.

It may also help you:

• Clear the debt sooner.
• Make fewer scheduled repayments.
• Reduce your exposure to recurring fees.
• Free up room in your future budget earlier.

However, the higher repayment amount still needs to be affordable.

Before selecting a shorter term, prepare a realistic budget that includes your essential expenses and allows for less predictable costs such as:

• Car repairs.
• Medical expenses.
• Annual bills.
• Unexpected household costs.

Our guide to managing your budget can help you review your income and expenses before deciding which repayment amount may be manageable.

Is a Longer Loan Term Always a Bad Choice?

Not necessarily.

A longer term may provide lower scheduled repayments, which can make each payment easier to accommodate within your regular budget.

The trade-off is that you may pay more interest overall.

The goal is not simply to choose the shortest or longest possible term. You should consider the balance between:

• An affordable repayment amount.
• The total interest and fees.
• How long you will remain in debt.
• Enough room in your budget for essential living costs.
• Some flexibility for unexpected expenses.

Repayments that are too high can increase the risk of missed payments.

At the same time, extending a loan longer than necessary may increase its total cost.

Does Repayment Frequency Affect the Total Cost?

Repayment frequency describes how often you make payments, such as weekly, fortnightly or monthly.

More frequent repayments can sometimes reduce a loan balance sooner, but only when the repayment structure means you are paying more over the same period or the way interest is calculated creates a saving.

Simply changing from monthly repayments to fortnightly repayments does not automatically guarantee a lower total cost.

Check the actual:

• Repayment amount.
• Number of repayments.
• Loan term.
• Interest calculation method.
• Contract conditions.

Before making additional repayments, you should also confirm:

• Whether extra payments are allowed.
• Whether they reduce your principal immediately.
• Whether any fees or limits apply.

Moneysmart notes that making additional repayments can reduce total interest and help you repay a personal loan sooner, but you should check the applicable terms and fees first.

You can also read our guide to paying back a loan faster. Your own credit contract should always be your starting point before changing a repayment arrangement.

How to Compare Different Loan Terms

When you have more than one term available, compare the complete repayment information rather than looking only at the smallest scheduled repayment.

1. Compare the Same Loan Amount

Make sure each option is based on the same amount borrowed.

Comparing a six-month loan for one amount with a 12-month loan for a different amount will not show you the effect of the term alone.

2. Check the Total Amount Repayable

Look at how much you would have paid by the time all scheduled repayments were completed.

This can give you a clearer picture of the overall cost than the weekly or fortnightly repayment alone.

3. Separate Interest From Fees

Check how much of the borrowing cost comes from interest and how much comes from establishment, ongoing or conditional fees.

A personal loan calculator may help illustrate how different terms affect estimated repayments and total repayments.

Remember that calculator results are estimates and may not include every fee or condition applying to a particular loan.

4. Check Whether the Rate Is Fixed or Variable

A fixed interest rate generally remains unchanged for the agreed fixed-rate period, while a variable rate can change.

If you are considering a variable-rate loan, a longer term may leave you exposed to possible rate changes for a longer period.

5. Test the Repayment Against Your Budget

Consider whether you could make each repayment after paying for essential living expenses.

Try not to base your decision on your best financial week. Allow for ordinary variations in expenses and some unexpected costs.

6. Read the Early Repayment Conditions

Paying a loan out early can reduce interest in some circumstances, but individual credit products may have different fees, restrictions and calculation methods.

Check your contract rather than assuming an early repayment will always produce the same saving.

How Our Loan Terms Work

We provide unsecured Medium Amount Credit Contracts to eligible Australian consumers.

Our current product features include:

You can review our loan costs for more information about these charges and our current representative repayment example.

You can also repay your loan with us early without an early payout fee.

Repaying the loan sooner may reduce the interest you pay because interest will no longer continue to accrue on the outstanding balance after it has been repaid.

We assess every application individually.

As part of our responsible lending obligations, we:

• Make reasonable inquiries about your financial situation.
• Make reasonable inquiries about your requirements and objectives.
• Take reasonable steps to verify relevant financial information.
• Assess whether the proposed credit contract would be unsuitable for you.
• Do not enter into a credit contract that is unsuitable for you.

Approval is never automatic and remains subject to our eligibility requirements, assessment and approval.

Before you apply, we encourage you to review our eligibility requirements and consider whether the repayments can be made without creating financial hardship.

Consider Alternatives Before Borrowing for Longer

Borrowing is not the only way to manage a one-off expense.

Before taking out a loan or extending a borrowing period simply to lower your repayments, you may want to consider whether you could:

• Use available savings.
• Delay a non-essential purchase.
• Request a payment plan from the service provider.
• Ask whether hardship assistance is available.
• Review your budget for temporary savings.
• Compare other suitable credit options.
• Check whether you qualify for a No Interest Loan or community-based lending program.

A longer loan term can make each repayment smaller, but it will not fix an ongoing gap between your regular income and essential expenses.

If you are having trouble paying for ordinary living costs or existing debts, taking on further credit may make your financial position harder to manage.

Frequently Asked Questions

Does a Longer Loan Term Reduce My Repayments?

A longer term will often reduce each scheduled repayment because the balance is spread across more payments.

However, you may pay more interest overall because the balance remains outstanding for longer.

Does the Shortest Loan Term Always Have the Lowest Cost?

A shorter term will generally reduce interest when the amount borrowed, interest rate and other loan features remain the same.

However, fees, interest-calculation methods and contract conditions can affect the final amount you repay.

You should also make sure the higher repayments are affordable within your budget.

What Should I Compare Besides the Interest Rate?

We recommend looking at:

• The total amount repayable.
• Establishment fees.
• Ongoing fees.
• Default fees.
• Repayment frequency.
• The loan term.
• Early repayment conditions.

You should also check whether the interest rate is fixed or variable, when relevant.

Can I Change My Loan Term After Accepting the Contract?

Your options will depend on your credit contract and circumstances.

Changing an agreed repayment arrangement may require a contract variation or another arrangement with your credit provider.

If you have a loan with us and think you may have difficulty making a scheduled payment, contact us as early as possible so that we can discuss which options may be available.

Will Paying a Loan Off Early Reduce Its Total Cost?

It may.

Paying a loan out early can reduce the period during which interest is charged, although the outcome depends on your contract and whether early repayment fees apply.

With our current loans, you can repay your loan early without an early payout fee.

How Do I Choose an Affordable Loan Term?

Start by reviewing your income and essential expenses.

Compare the total cost of the available terms and consider a repayment amount that leaves room for ordinary living costs and unexpected bills.

Avoid choosing a repayment amount based solely on the maximum you could afford during an unusually good week.

Review Both the Repayment and the Total Cost

Your loan term affects more than the date of your final repayment.

It can influence:

• Your scheduled repayments.
• The amount of interest charged.
• The fees you may pay.
• The total amount you repay.
• How long the debt remains in place.

A shorter term may reduce your overall borrowing cost but result in higher regular repayments.

A longer term may reduce each repayment while keeping the debt in place for longer and potentially increasing the interest you pay.

Before deciding, compare the complete cost of the loan, check the repayments against your budget and consider whether there are suitable alternatives to borrowing.
