When A Repair Stops Being Worth It

A quote to repair an ageing appliance invites a decision that usually gets made on feeling. It can be made on numbers instead, and the numbers are ones a household already has.

The comparison is cost per remaining year

A repair buys some further period of service. Divide its cost by the years it plausibly adds, and compare that against the price of a replacement divided by its expected life.

A modest repair on a machine with years left almost always wins. A large repair on a machine near the end of its typical life usually does not.

The figure that decides it is expected remaining life, which is the part people guess at without realising they are guessing.

Typical service life is knowable

Most appliance categories have a well-understood span, and repairers see enough units to know it. Asking the person quoting how long the machine should last is a reasonable question.

Usage intensity shifts that span considerably. A machine run several times a day ages far faster than the same model run twice a week.

Where a machine is well past the typical span, a repair is buying a shorter period than the same repair on a younger one.

Diagnosis costs are already spent

Many repairers charge to attend and diagnose, deducting it from the repair if the work proceeds. That structure means declining the repair still costs the diagnosis.

Since it is spent either way, it should not enter the comparison. The decision is between the remaining repair cost and a replacement.

Treating it as part of the repair price is a common error that pushes households towards replacement more often than the arithmetic supports.

Running cost belongs in the calculation

For appliances that consume significant energy or water, a newer machine may cost less to run. That difference accumulates over the life of the replacement.

Where a machine runs constantly, the running-cost difference can outweigh a moderate repair bill within a few years.

Where it runs occasionally, the difference is small and the repair almost always wins on cost.

Timing is part of the answer

A machine that has already needed two repairs is telling you about its remaining life, and a third quote should be evaluated against that history rather than in isolation.

Replacing at a moment of your choosing is cheaper than replacing under pressure, because urgent purchases are made from whatever is available at whatever price.

A failing machine that still works is therefore the best possible position from which to buy a new one.

That position also allows the replacement to be chosen on merit rather than on what can be delivered this week, which is often where the larger saving sits.
