Equipment Lifespan Calculator
Estimates remaining life and replacement timeline for major equipment based on age and condition.
How it works
Lifespan: Pump 8-10yr, Filter Housing 10-15yr, Motor 10-12yr, Heater 8-15yr, Salt Cell 3-7yr, Cartridge 2-3yrReplacement 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.

Reference table
| Rule of thumb | What it means |
|---|---|
| The 50% rule | If a repair costs half the price of new, replacing is often smarter |
| Last year of life | Near the end of expected life, lean toward replacing |
| Efficiency gains | New 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.
