When to Repair vs Replace: Singapore Homeowner Guide

The Repair vs Replace Dilemma

Every homeowner faces this question: Is it worth fixing, or should I just buy new? This guide helps you make smart decisions based on costs, age, and value.

The 50% Rule

General guideline: If repair costs exceed 50% of replacement cost, consider replacing.

But also consider:

• Age of the item
• Frequency of repairs
• Energy efficiency of new models
• Warranty on repairs vs new

Cost Comparison Calculator

Quick Formula

Repair Value = (Expected remaining life × Annual value) - Repair cost
Replace Value = (New item lifespan × Annual value) - Purchase cost

Choose the higher value option.

Example: 8-year-old Aircon

• Compressor repair: $500
• Expected remaining life after repair: 3 years
• New unit cost: $1,500
• New unit lifespan: 10 years

Analysis:

• Repair: 3 years of use for $500 = $167/year
• Replace: 10 years of use for $1,500 = $150/year

Verdict: Replace (better long-term value)

Energy Efficiency Factor

Older appliances often use more electricity. Consider:

A new efficient appliance may pay for itself in electricity savings.

Questions to Ask

Before deciding, ask:

1. How old is it? Near end of typical lifespan?
2. What's the repair cost? Over 50% of new?
3. Is this a recurring issue? Multiple repairs recently?
4. Will parts be available? Older models may lack parts
5. What's the energy impact? New models more efficient?

When Repair Always Makes Sense

• Item is under warranty
• Minor issue, low repair cost
• Relatively new (under 3 years)
• High-quality item worth maintaining
• Sentimental value

When Replace Always Makes Sense

• Safety concerns
• Obsolete technology (R22 aircon)
