When a major appliance breaks down, most Australians face the same moment of indecision: Is it cheaper to fix this, or should I buy new? Without a clear framework, the answer always feels like a guess. You look up the repair cost, check the price of a replacement, and still are not sure which number wins.
This guide gives you a clear, practical framework for making the repair or replace decision across the major appliances in your home, including fridges, washing machines, dishwashers, and ovens.
The Core Framework: Three Numbers You Need
Every repair or replace decision comes down to three numbers and the relationship between them.
- The first number is the repair cost. This is the full, all-in cost of the repair including parts, labour, and any call-out or diagnostic fee. Always get a proper diagnostic and written quote before using this number.
- The second number is the replacement cost. This is the cost of purchasing a comparable new appliance of similar capacity and quality tier. If you have a 500-litre fridge, the relevant comparison is a 500-litre fridge, not the cheapest possible small alternative.
- The third number is the remaining useful life of your appliance. This is where most people’s thinking is haziest. An appliance at the halfway point of its expected lifespan has very different repair economics than one that is approaching the end.
The 50 Percent Rule
The most widely referenced guideline in appliance repair economics is the 50 percent rule: if the repair cost exceeds 50 percent of the cost of a new comparable appliance, replacement is generally the better financial decision.
This rule has merit as a quick filter. If your dishwasher would cost $900 to replace and the repair quote is $200, you do not need a complex analysis. Repair wins clearly. If the repair quote is $600, you need to think more carefully and bring in the other factors.
Expected Lifespans for Major Australian Appliances
Understanding where your appliance sits in its expected lifespan is critical to making a sound decision. Here are realistic average lifespans for common Australian home appliances under normal household use.
Fridges and refrigerators in Australia have an average lifespan of 14 to 17 years for quality brands. Budget brands are 10 to 13 years.
Washing machines last 10 to 13 years for standard front-load and top-load models. Premium European brands can last 15 years or more with proper maintenance.
Dishwashers have an average lifespan of 9 to 12 years for standard models and 12 to 15 years for premium European brands like Bosch and Miele.
Electric ovens and cooktops tend to last 13 to 15 years under regular household use.
Air conditioning systems, including split systems, last 10 to 15 years depending on maintenance frequency and usage intensity.
These are averages. A well-maintained appliance from a quality brand can exceed these figures. An appliance that has been poorly maintained or used intensively may fall short.
The Age-Adjusted Repair Rule
The 50 percent rule works well for appliances in the middle of their expected lifespan but becomes less useful at the extremes. Here is a more nuanced age-adjusted framework.
If your appliance is in the first third of its expected lifespan, repair always makes sense unless the fault is catastrophic. A fridge that is five years old with a failed fan motor is worth repairing regardless of the cost relative to replacement, because you have ten or more years of service life remaining to recover that investment.
If your appliance is in the middle third of its expected lifespan, the 50 percent rule applies cleanly. Use the repair cost divided by replacement cost as your primary decision variable, with brand quality and energy efficiency as secondary factors.
If your appliance is in the final third of its expected lifespan, the calculation shifts. A fridge that is 14 years old and at the end of its expected life may not justify even a moderately priced repair, because the money you invest in the repair may only buy you another one to two years of service before another fault appears. Here, replacement makes more sense unless the repair is genuinely minor and inexpensive.
The Repair or Replace Calculator: Applied to Each Appliance
Here is how to apply the framework practically for each major appliance category.
Fridge
Expected lifespan: 14 to 17 years (quality brands).
Typical replacement cost in Australia: $900 to $3,000 depending on size and brand.
Repair cost threshold (50 percent rule): $450 to $1,500.
Common repairs and their Brisbane cost:
Thermostat replacement ($120 to $200),
Fan motor replacement ($150 to $280),
Defrost system repair ($180 to $320),
Compressor replacement ($400 to $800 in parts plus labour).
Quick calculation: Take the repair quote, divide it by the replacement cost, and multiply by 100 to get a percentage. If the result is under 50 and the fridge is not in its final third of lifespan, repair is the right call.
Washing Machine
Expected lifespan: 10 to 13 years.
Typical replacement cost in Australia: $600 to $2,500 depending on type and brand.
Repair cost threshold (50 percent rule): $300 to $1,250.
Common repairs and typical Brisbane cost:
Pump replacement ($120 to $220),
Door seal replacement ($150 to $300),
Bearing replacement ($200 to $400), exceeding to 600+ for premium machines.
Control board replacement ($250 to $500).
Note: Washing machine bearing failure is a nuanced situation. The repair itself can be moderately expensive and labour-intensive, but on a quality brand like Bosch or Miele with several years of life remaining, it is worth it. On a budget brand near the end of its lifespan, replacement is the better call.
Dishwasher
Expected lifespan: 9 to 12 years for standard, up to 15 for premium.
Typical replacement cost in Australia: $700 to $2,200.
Repair cost threshold: $350 to $1,100.
Common repairs and typical Brisbane cost:
Pump or motor replacement ($180 to $350),
Door latch or seal ($80 to $180),
Control board ($200 to $450),
Spray arm or filter cleaning and replacement ($60 to $150).
Most dishwasher repairs fall well below the replacement cost threshold, making repair the sensible choice in the majority of cases.
Oven and Cooktop
Expected lifespan: 13 to 15 years.
Typical replacement cost in Australia: $600 to $3,000 depending on type.
Repair cost threshold: $300 to $1,500.
Common repairs and typical Brisbane cost:
Element replacement ($100 to $220),
Thermostat replacement ($130 to $250),
Door seal or hinge ($80 to $180),
Control board ($200 to $450).
Ovens and cooktops tend to have highly cost-effective repair options because the most common faults involve discrete, replaceable components that are widely available.
The Hidden Costs of Replacement
Many Australians underestimate the true cost of replacing an appliance. The sticker price of the new unit is only the beginning. Delivery and installation fees add $100 to $300 for most major appliances. Old appliance removal and disposal, if the retailer does not include it, can add another $50 to $150. If a new fridge or dishwasher requires modifications to cabinetry, plumbing, or electrical connections, costs can rise further.
There is also the time cost. Researching, purchasing, coordinating delivery, and waiting at home for the installation takes a meaningful chunk of time out of your week.
For most single-fault appliance repairs, a competent technician can diagnose and fix the issue in one same-day visit, getting your household back to normal with minimal disruption.
Energy Efficiency: The Long-Term Running Cost Factor
For appliances that have been running for ten years or more, it is worth considering the energy efficiency gap between your current appliance and a modern replacement. This is relevant for fridges and air conditioning systems, which run continuously or near-continuously.
Modern appliances carry an Energy Star Rating label in Australia. A new fridge with a higher star rating will use measurably less electricity than a ten-year-old equivalent running at reduced efficiency due to age. Depending on your current electricity tariff in Queensland, this saving can be $50 to $150 per year.
To factor this in, estimate how many years of service life your repaired appliance has remaining, multiply the annual energy saving by those years, and subtract from the repair cost differential. In many cases this does not tip the calculation strongly either way, but for older, energy-hungry appliances nearing end of life it can be a meaningful addition to the analysis.
What a Good Technician Will Tell You
Here is something that separates great appliance repair technicians from average ones: the willingness to tell you honestly when replacement makes more sense than repair.
A technician who is looking out for your interests will give you the repair quote, tell you honestly about the remaining life of the appliance, flag if any other components are showing signs of early wear, and tell you whether they believe the repair represents good value for your specific situation.
The team at Ideal Refrigeration and Appliance Services approaches every job this way. Technicians has been reviewed multiple times for giving honest advice, including telling customers when a new appliance is the better financial call. That kind of transparency builds trust and helps Brisbane homeowners make genuinely informed decisions.

Frequently Asked Questions
Is there an actual appliance repair or replacement calculator I can use?
While there is no single standardised calculator, this framework effectively functions as one. Take the repair cost as a percentage of replacement cost, check the appliance’s age against its expected lifespan, and factor in running cost and brand quality. These four variables will give you a clear answer in most cases.
Should I repair a cheap appliance or just replace it?
For very low-cost budget appliances, the economics of repair are less favourable because the replacement cost is already low and the build quality means further faults will follow. Apply the 50 percent rule for budget appliances and lean toward replacement when the calculation is borderline.
Does it make sense to repair a commercial refrigerator in Brisbane?
Yes, very much so. Commercial refrigeration equipment is expensive to replace and built to be serviced. A professional diagnosis and repair from a qualified commercial refrigeration technician always delivers better value than full replacement.
How do I know if my repair quote is reasonable?
A transparent, qualified technician will break down the quote into parts and labour and explain what is being replaced and why. Compare the quote against the replacement cost using the 50 percent rule and seek a second opinion if the quote feels unusually high for the described fault.
What is the most common appliance repair that is definitely worth doing in Australia?
Fridge fan motor repairs, thermostat replacements, and dishwasher pump repairs are consistently cost-effective repairs across Australia. They resolve specific, contained faults at a fraction of replacement cost, with genuine life remaining in the appliance.
