Decision guide
Repair it, or replace it?
There is one rule everybody quotes and a second one that disagrees with it. This page works both out for all 12 appliance types and for the 89 repairs priced on this site, because the answer is not a rule — it is a number, and it is a different number on a $200 garbage disposal than on a $1,200 refrigerator.

The two rules, and where they part company
Both are worth knowing because they answer slightly different questions, and on an appliance that is more than a few years old they routinely disagree.
Rule one
Half the price of a new one
If the repair quote is more than half the price of an equivalent new unit, replacement is usually the better spend. Below half, repair almost always wins on cost per remaining year of service.
It needs one number you can look up, which is why every technician quotes it. Its weakness is that it ignores age completely: it gives the same answer on a two-year-old machine and a twelve-year-old one.
Rule two
Half of what yours is worth today
The stricter version is to spend no more than half of what the appliance is worth today, which is the ceiling the value estimator returns. At age zero the two rules give exactly the same number, because a brand-new unit is worth what a new unit costs. Every year after that they diverge: the price of a replacement stays where it is while the value of yours falls.
It is the stricter test and it is the one the value estimator reports as your repair ceiling, because it accounts for age: an eight-year-old refrigerator is not worth half of a new one, it is worth half of an eight-year-old one.
Then check the age against expected lifespan. An appliance past roughly three-quarters of its expected life has little runway left to earn back a large repair, so the threshold drops as the machine gets older — on an old unit, a repair at a third of new price can still be the wrong call.
The line, appliance by appliance
Where each appliance's fixed threshold sits, how long it is expected to last, the ages at which this site's value model changes its verdict, and the last year the cheapest priced repair on that appliance still pays back. Sorted commonest first.
| Appliance | New unit | Replace above | Expected life | Borderline from | Replace from | Cheapest repair pays through |
|---|---|---|---|---|---|---|
| Refrigerator | $1,200 | $600 | 14 yr | 10 yr | 12 yr | Year 12 |
| Washer | $800 | $400 | 11 yr | 8 yr | 10 yr | Year 9 |
| Dryer | $750 | $375 | 12 yr | 8 yr | 11 yr | Year 7 |
| Dishwasher | $700 | $350 | 10 yr | 7 yr | 9 yr | Year 6 |
| Oven & Range | $1,000 | $500 | 14 yr | 10 yr | 12 yr | Year 15 |
| Microwave | $250 | $125 | 9 yr | 6 yr | 8 yr | New only |
| Garbage Disposal | $200 | $100 | 10 yr | 7 yr | 9 yr | New only |
| Ice Maker | $400 | $200 | 8 yr | 6 yr | 7 yr | Year 4 |
| Freezer | $600 | $300 | 15 yr | 10 yr | 13 yr | Year 10 |
| Wine Cooler | $500 | $250 | 10 yr | 7 yr | 9 yr | New only |
| Range Hood | $350 | $175 | 14 yr | 10 yr | 12 yr | Year 6 |
| Trash Compactor | $800 | $400 | 10 yr | 7 yr | 9 yr | Year 9 |
"Replace above" is half the price of a mainstream new unit. "Borderline from" and "replace from" are read off this site's value model rather than asserted — the page probes the same function the estimator runs, so these ages cannot drift out of step with the tool. The last column applies the stricter rule to the least expensive repair priced for that appliance, which is the bluntest reading available: once even that job is over the ceiling, nothing else on the menu clears it either.
Where the two rules disagree
Taken at roughly half of each appliance's expected life: how many of its priced repairs the fixed rule still approves, against how many the value-today ceiling still approves. The gap is the argument.
| Appliance | At age | Ceiling then | Repairs the fixed rule allows | Repairs the ceiling allows |
|---|---|---|---|---|
| Washer | 6 yr | $186 | 8 of 8 | 1 of 8 |
| Dishwasher | 5 yr | $147 | 8 of 8 | 1 of 8 |
| Refrigerator | 7 yr | $245 | 8 of 8 | 2 of 8 |
| Wine Cooler | 5 yr | $132 | 6 of 8 | 0 of 8 |
| Trash Compactor | 5 yr | $211 | 8 of 8 | 2 of 8 |
| Dryer | 6 yr | $174 | 8 of 8 | 3 of 8 |
| Ice Maker | 4 yr | $100 | 6 of 8 | 1 of 8 |
| Freezer | 8 yr | $141 | 6 of 8 | 1 of 8 |
| Range Hood | 7 yr | $91 | 5 of 6 | 0 of 6 |
| Oven & Range | 7 yr | $259 | 8 of 8 | 4 of 8 |
| Garbage Disposal | 5 yr | $42 | 4 of 4 | 0 of 4 |
| Microwave | 5 yr | $53 | 3 of 7 | 0 of 7 |
Which one should you use
The fixed rule if the appliance is young, the value-today ceiling if it is not, and both if the quote lands between them — that gap is where the decision is genuinely a judgement rather than a calculation. Neither rule knows how well the machine has been looked after, and that is the input you have and they do not.
Why the gap is widest on cheap appliances
A repair has a floor: a technician has to drive to you, diagnose the fault and fit a part, and that costs roughly the same whether the appliance cost $200 or $1,200. So on an inexpensive appliance the ceiling passes under the floor early, and the answer stops depending on which fault you have.
What your appliance is actually worth
The ceiling is half of a value, so the value has to come from somewhere. This site computes it from four inputs and publishes all four.
Input one
The price of a new one
An editorial estimate per appliance type, from $200 to $1,200 for a mainstream unit. Everything else multiplies this.
Input two
The brand tier
A single multiplier on that starting price, and the only thing brand does here. It does not change the expected life or the rate of depreciation.
Input three
Age, compounded
Three depreciation curves assigned by appliance type. A garbage disposal is on the fast curve, a freezer on the slow one, which is why their ceilings fall at different rates from different starting points.
Input four
Condition, honestly
The one input the model cannot check and the one that moves the answer most at the bottom end. Rating a broken appliance kindly is how you get a flattering number.
Every ceiling on this page is half the value the estimator gives a unit of that age in excellent condition. Excellent is deliberately the generous end of the model — it values the appliance as it will be once the fault is fixed, which is what the repair is actually buying. Rate your own unit honestly in the estimator and every figure here moves down.
Appliance Blue Book
Run the four inputs on your own appliance
Everything on this page is the mainstream case. The estimator takes your appliance type, brand, age and condition and returns what it is worth today, how much of its life is left, and the repair ceiling that follows — with the whole method written out so you can judge it rather than trust it.
Three things the arithmetic does not know
The thresholds are a starting point. These override them, and two of the three push in the opposite direction to what the numbers say.
- What replacement really costs
- Every threshold here is built from the price of the appliance, which is not the price of the job. A built-in, stacked, ducted or plumbed appliance carries cabinetry, ductwork, plumbing or an electrical connection with it, and those push the real line higher than the arithmetic suggests. That is why the same fault can be worth repairing on a built-in unit and not on the freestanding version of it. Each appliance page below sets out what replacing that one actually involves.
- What breaks next
- A repair does not buy a new appliance, it buys one new part in an appliance where everything else is the same age and has done the same work. On most machines the failures come in a recognisable order, so the honest comparison is not this quote against a replacement but this quote plus the next one or two. A second failure on the same machine inside a year is that argument arriving on its own.
- What is not a cost decision
- Three things override the arithmetic entirely. Safety is not a cost decision: an appliance that is a fire, gas, water or electrical hazard comes out of service regardless of what a repair would cost. A part that is discontinued ends the conversation whatever the quote was going to be. And a second failure on the same machine inside a year is telling you about the rest of the components, not about the one that just broke.
None of this includes the diagnostic fee, which is charged for the visit and the diagnosis whether the verdict is good or bad. Many shops credit it against the repair if you approve the work the same day and many do not, so ask before the van is dispatched rather than after.
Work it out for one appliance
Each page takes that appliance's priced repairs, judges every one against both rules, and sets out what makes the decision different there — including what replacing it actually involves and what tends to fail next.
The four appliances that anchor the range
Every other appliance sits between these, and knowing which end yours is nearer is most of the answer before you look up a single figure.
Highest line
$600
Refrigerator
A $1,200 replacement leaves room for almost everything on its repair menu. The expensive faults are the ones that open the sealed system.
Lowest line
$100
Garbage Disposal
A $200 appliance sets a line that very few repairs with labour attached stay under. Here the fitted price of a replacement matters more than the sticker.
Longest life
15 yr
Freezer
On the holds value well curve, so its ceiling stays useful for longer than its modest replacement price suggests.
Shortest life
8 yr
Ice Maker
The clock runs out first here, which is why its verdict turns borderline at year 6 — sooner than on anything else listed.
Typical repair bands for comparison: $200–$400 on a refrigerator, $85–$250 on a garbage disposal. Set each against its own line rather than against the other, which is the mistake that makes an expensive appliance look unrepairable and a cheap one look worth saving.
