All repairs and routine maintenance over the past year.
Lost production, idle labour, or missed revenue caused by this asset failing. Defaults to £0 if left blank.
50% Rule: If the repair cost exceeds 50% of the replacement cost, replacement is generally more economical. Below 30%, repair is usually the right call. 30–50% is a judgement zone.
3-year cost comparison: Repair path = repair cost + current annual maintenance spend × 3 + downtime cost × 3. Replace path = replacement cost + 40% of current annual maintenance × 3 + 40% of downtime cost × 3 (reflecting typical reliability improvements from a newer asset).
Age & criticality nudge: Assets older than 10 years in high or critical roles carry elevated risk of further failures. When both conditions apply, the calculator nudges the recommendation toward Replace or Marginal.
Results are estimates based on conservative industry benchmarks. Actual savings depend on asset type, operating environment, and specific circumstances. Use this as a starting point, not a substitute for a full life-cycle cost analysis.
