Key takeaways

• Two kinds of saving: Refinancing can cut your total interest, or lower your monthly repayment to ease cash flow. They are not the same thing, so be clear which you are chasing.
• Rate cuts compound: Even a one or two percentage point drop on a large balance can save thousands over the life of the loan.
• Consolidation saves on fees: Rolling several facilities into one can strip out duplicate monthly and account fees on top of any rate benefit.
• Costs eat into the gain: Exit fees, establishment fees, and a longer term all reduce the net saving, so always calculate the total cost of ownership, not just the price tag.
• Run your own numbers: Savings depend entirely on your balance, rate, term, and fees, so a comparison against your actual loan is the only way to know.

Refinancing a business loan is often pitched as a way to save money, but how much you actually save depends on your specific loan and what you are trying to achieve. With the Reserve Bank cash rate sitting at 4.35 per cent in mid-2026 after a series of increases, the cost of borrowing has climbed, which makes it more important than ever to know whether your current loan is still working for you. This guide walks through where the savings come from, how to estimate them for your own loan, and the costs that can quietly reduce the benefit.

Where refinancing savings actually come from

Before you can estimate a saving, you need to know which lever you are pulling. Refinancing delivers value in a few distinct ways, and they do not all reduce the total cost of your loan:

• A lower interest rate: This is the classic saving. A lower rate on the same balance and term reduces both your monthly repayment and the total interest you pay. This is the only lever that reliably cuts total cost.
• A longer term: Stretching the loan over more months lowers each repayment, which helps cash flow, but usually increases total interest. This is relief, not a saving.
• Consolidating facilities: Combining several loans into one can remove duplicate account fees and monthly facility fees, and may secure a better blended rate than the individual loans carried.
• Lower fees: A product with the same rate but fewer ongoing charges saves money without touching the interest rate at all.

Knowing which of these applies to your situation is the difference between a real saving and simply moving the cost around. Cutting the rate lowers what the loan costs you. Extending the term lowers what you pay this month but often raises what you pay overall.

A worked example

The clearest way to see the effect is with numbers. Take a business carrying a $150,000 loan over a five-year term. The table below shows indicative monthly repayments and total interest at a few different rates, to illustrate how much a rate change can be worth. These are illustrative figures only, not a quote:

In this example, dropping from 12 per cent to 8 per cent saves roughly $296 a month and around $17,700 in total interest over the five years. Even a two point cut, from 12 per cent to 10 per cent, saves close to $9,000 across the loan. That is the power of a rate reduction on a sizeable balance: small percentage differences compound into real money over a full term.

How to estimate your own saving

Your saving will not match the example unless your loan does. To estimate your own, work through these steps:

• Pull your current numbers: Note your outstanding balance, your current interest rate, your remaining term, and every fee you pay, including monthly and annual charges.
• Get comparable offers: Find the rate, term, and fees on the products you could switch to. Compare like for like, since a lower rate over a longer term can still cost more overall.
• Compare total cost, not the rate alone: Add establishment fees and ongoing fees to the interest for each option. The cheapest headline rate is not always the lowest total cost.
• Subtract the switching cost: Deduct any exit or discharge fees on your current loan and establishment fees on the new one. What remains is your genuine net saving.

A refinancing calculator can speed this up, but the discipline is the same: measure the full cost of staying against the full cost of switching, including every fee on both sides.

The costs that reduce your saving

A saving on paper can shrink once the costs of switching are counted. The main ones to watch:

• Exit or discharge fees: Your current lender may charge to close the loan early, particularly on fixed rate facilities. This is a one-off cost that eats into the first year of savings.
• Establishment fees: The new lender may charge a setup or application fee, often a percentage of the facility. Strong borrowers can sometimes have this reduced or waived.
• A longer term: Extending the term lowers your monthly repayment but adds interest over the extra months. Lower repayments do not always mean a lower total cost.
• Break costs on fixed loans: Exiting a fixed rate loan early can trigger break costs that can be significant depending on the loan and timing.

None of these should necessarily stop you refinancing, but they need to be in the calculation. A switch that looks like a strong saving on the rate can turn marginal once a hefty exit fee and a longer term are counted in.

A realistic scenario

Picture a hospitality business carrying a $120,000 equipment loan at 12 per cent with two years left, plus a separate small working capital facility with its own monthly fee. Cash flow is steady but the repayments feel heavy, and the owner has never checked whether the rate is still competitive.

A comparison shows the business now qualifies for around 9 per cent, thanks to three solid years of trading since the original loan. Consolidating the working capital facility into the refinanced loan also removes a duplicate monthly fee. After accounting for a modest discharge fee and a new establishment fee, the owner comes out ahead on both the monthly repayment and the total interest, and drops from two repayment dates to one. The saving is real because the rate genuinely fell and a fee was removed, not because the term was stretched to mask the cost.

Frequently asked questions

How much can I realistically save?

It depends entirely on your balance, current rate, term, and fees. Savings can range from a few hundred dollars to many thousands over the life of the loan. The only reliable figure is one calculated against your actual loan, including all switching costs.

Does a lower monthly repayment always mean I am saving?

No. A lower monthly repayment often comes from a longer term, which can increase the total interest you pay. A lower repayment helps cash flow, but a true saving on total cost comes from a lower rate or lower fees.

Is it worth refinancing if I only have a year or two left?

Sometimes. With a short remaining term, the interest saving is smaller and switching costs weigh more heavily, so the maths is tighter. It can still make sense for consolidation or to clear a balloon, but check that the net benefit survives the fees.

What matters most

The honest answer to how much you could save is: it depends, and the only way to know is to run your own numbers. Be clear whether you are chasing a lower total cost or a lower monthly repayment, compare offers on total cost rather than the headline rate, and subtract every switching fee before you decide. Done properly, refinancing a business loan can save thousands. Done on the rate alone, it can quietly cost you. This is general information, not financial advice, so confirm the figures with your accountant against your own loan.
