Starting with total cost, not just the rate
A common mistake when evaluating refinancing is comparing only the interest rate on the current loan against the rate on a new one, without accounting for the full picture. A more accurate approach typically starts by working out the total cost of continuing with the current loan over a defined period, including interest, any ongoing fees, and remaining loan term, and comparing this against the total cost of the new loan over the same period, including its interest, fees and any establishment costs. This total-cost approach captures the reality that a lower rate doesn't automatically mean lower overall cost if the new loan carries higher fees, a longer term that increases total interest paid, or other costs not immediately obvious. It's also important to compare like-for-like loan features, since a new loan with fewer features, such as no offset account or redraw facility, might look cheaper on paper but could cost more in practice depending on how the borrower uses the loan. Getting a clear breakdown of all costs, ideally from both the current and prospective lender, is the foundation for any genuine refinancing comparison, and this should include indicative figures only since exact costs can change until settlement.
Understanding break costs
Break costs, where applicable, are typically charged when a borrower exits a loan before the end of a fixed-rate period or fixed term, and they exist because the lender has generally priced the loan based on funding arrangements tied to that fixed term. If market rates have moved since the fixed rate was set, the lender may incur a cost when the loan is repaid early, and this cost is often passed on to the borrower as a break fee. Break costs are typically calculated based on factors such as the remaining fixed term, the difference between the original fixed rate and current market rates, and the outstanding loan balance, though the exact calculation method varies by lender and is usually set out in the loan contract. Because break costs can sometimes be significant, particularly with a large loan balance and a long remaining fixed term, it's important to request an indicative break cost figure directly from the current lender before proceeding with refinancing plans. Variable rate loans typically do not carry break costs in the same way, though other exit fees or discharge fees may still apply, so checking the specific loan contract terms is essential regardless of whether the loan is fixed or variable.
Other costs that affect the comparison
Beyond break costs, several other costs typically need to be factored into a refinancing comparison. These can include discharge fees from the current lender for closing the loan, application or establishment fees for the new loan, and costs such as valuation fees, legal or settlement fees, and any government charges that may apply depending on the type of loan and security involved. Some new loans may also carry ongoing account-keeping fees that differ from the current loan, which affects the long-term comparison even if the upfront costs are similar. If the current loan has features being given up, such as an offset account, it's worth considering the value of interest savings that feature was providing, since this is a real cost of switching even though it isn't a standalone fee. Some new lenders offer cashback or fee waivers as an incentive to refinance, which can offset some switching costs, but these should be weighed against the ongoing cost of the new loan over its full term rather than treated as a reason to refinance on their own. Collecting a full list of one-off and ongoing costs from both lenders is essential before calculating whether refinancing pays off.
Calculating the break-even point
The break-even point is typically the point in time at which the cumulative savings from a lower-cost loan equal the total upfront costs incurred to switch, such as break costs, discharge fees and new establishment costs. A simple way to think about this is dividing the total switching costs by the estimated ongoing monthly or annual saving from the new loan, which gives an approximate timeframe for when the switch starts to genuinely pay off. For example, if switching costs total a certain amount and the new loan saves a certain amount per month compared with the old loan, dividing the former by the latter gives an approximate number of months to break even. If a borrower expects to keep the loan, or stay in the property or business arrangement it relates to, well beyond this break-even point, refinancing is more likely to be worthwhile financially. Conversely, if the borrower expects to repay the loan, sell the asset, or refinance again within a shorter period than the break-even point, the switching costs may not be recovered, making refinancing less attractive despite an apparently lower rate. This calculation should use indicative figures confirmed with actual lenders rather than assumptions, since fees and costs vary.
Practical steps before refinancing
Before proceeding with a refinance, it's worth requesting a written breakdown of all costs from both the current lender, including any break costs and discharge fees, and the prospective new lender, including all establishment and ongoing costs. Comparing these figures alongside the interest rate and loan features side by side, rather than relying on a single headline rate, gives a more accurate picture of whether refinancing makes sense. It's also worth considering how long the loan or facility is likely to remain in place, since this directly affects whether the break-even point will realistically be reached. If the numbers are close or unclear, discussing the specific figures with the current lender, the new lender, or an independent adviser can help clarify the decision. It's important to remember that every lender's fee structure and break cost calculation method can differ, so figures should always be confirmed directly rather than estimated from general assumptions. Because refinancing decisions can have long-term financial implications, taking the time to work through the full calculation, rather than acting on an attractive advertised rate alone, is generally the safer approach.
Key points
- Compare total cost of both loans, including fees, not just the headline interest rate.
- Break costs typically apply to fixed-rate loans repaid early and vary by lender and remaining term.
- Discharge fees, establishment costs and lost features all factor into the true cost of switching.
- The break-even point is when cumulative savings equal total switching costs.
- Refinancing is generally worthwhile only if you expect to hold the new loan beyond the break-even point.
Frequently asked questions
Do variable rate loans have break costs?
Variable rate loans typically do not carry break costs in the way fixed-rate loans do, though discharge or exit fees may still apply. It's important to check the specific loan contract to confirm what costs apply on exit.
How do I get an accurate break cost figure?
The most reliable way is to request an indicative break cost calculation directly from your current lender, since the method and inputs used can vary and figures change with market conditions and time remaining on the fixed term.
Is refinancing worth it if I plan to sell soon?
If you expect to sell or exit before reaching the break-even point, refinancing may not recover its switching costs, so it's worth calculating the break-even timeframe against your realistic plans before proceeding.
