Repair or replace: how to decide using total cost, not just price

Compare repair, useful life, energy use, warranty and replacement costs before deciding what to do with a faulty product.

A cheap repair can extend a product’s life by years; another may merely postpone an inevitable replacement for a few weeks. Making a comparison means considering safety, age, reliability, energy use, warranty coverage and total cost, rather than applying a universal percentage rule.

Check your rights and get a diagnosis

Review the receipt, purchase date, warranty and any manufacturer campaigns or recalls. Describe the fault precisely and request a diagnosis when reasonable. Do not open or repair equipment if doing so could create a hazard or invalidate applicable coverage.

The European Commission promotes information and options that make products more durable and repairable. Specific rights depend on the product, purchase date and country, so consult official sources.

Compare two complete scenarios

For a repair, add the cost of diagnosis, parts, labour, transport and time without the product. Ask what warranty covers the repair and what useful life can reasonably be expected afterwards. For a replacement, include delivery, installation, removal, accessories and financing costs.

  • Will the product still meet your needs?
  • Does the fault affect safety, or is it likely to happen again?
  • Is there a meaningful improvement in energy use or maintenance?
  • Can you wait and save for a better replacement?

Do not let urgency make the decision alone

Keep a small fund for household maintenance and record previous repairs. If you replace the product, compare the estimated annual cost based on its useful life, not only the purchase price. If you repair it, keep the invoice and a record of the parts replaced.

Kinset can display your household’s maintenance and purchase history so you can compare both options using real data. Technical and safety assessments should be carried out by qualified professionals.

If you would rather not organise receipts, bills, and statements by hand, Kinset can process them and help compare months, categories, and people in your household.
