Equipment Lifespan Calculator

Estimates remaining life and replacement timeline for major equipment based on age and condition.

Repair or replace?

How it works

  • Lifespan: Pump 8-10yr, Filter Housing 10-15yr, Motor 10-12yr, Heater 8-15yr, Salt Cell 3-7yr, Cartridge 2-3yr
  • Replacement trigger: Repair >50% replacement cost OR age >75% lifespan
You enter
Equipment type (pump/filter/heater/salt cell/motor), purchase date or age (years), manufacturing date/serial, repair cost estimate, last major repair date
You get
Typical lifespan (years), estimated replacement year, repair vs replacement threshold, condition warning level

How accurate is it? Lifespans vary by quality/maintenance; usage affects longevity; professional installation extends life.

These are estimates, not quotes. See How We Estimate.

Worked example

Pump purchased 6 years ago, 10-year typical life, recent $300 repair vs $1200 replacement: At 60% of lifespan, repair justified; plan replacement in 2-3 years.

Rule of thumbWhat it means
The 50% ruleIf a repair costs half the price of new, replacing is often smarter
Last year of lifeNear the end of expected life, lean toward replacing
Efficiency gainsNew variable-speed pumps can pay back through lower power bills

When to use it

Plan major capital expenditures; budget for equipment replacement before failure; evaluate repair vs replace.

Long-term maintenance planning, budget forecasting 3-5 years, repair vs replace decisions, evaluating upgrade ROI.
