How this calculator works
Side-by-side material cost for PEX vs copper by linear foot. Planning estimates only — verify measurements and local codes on site. Cost = linear ft × $/ft + fittings allowance for each material. Example: 60 ft run: PEX $1.2/ft vs copper $3.5/ft → ~$72 vs ~$210 materials.
Cost = linear ft × $/ft + fittings allowance for each material.
Example: 60 ft run: PEX $1.2/ft vs copper $3.5/ft → ~$72 vs ~$210 materials.
When to use this PEX vs Copper Cost

What you get
- Fields: Linear feet, PEX ($/ft), Copper ($/ft), Fittings allowance ($)
- Cost = linear ft × $/ft + fittings allowance for each material.
- Example on the page: 60 ft run: PEX $1.2/ft vs copper $3.5/ft → ~$72 vs ~$210 materials.
How to Calculate PEX vs Copper Cost Step-by-Step
- 1Enter Linear feet, PEX ($/ft), Copper ($/ft), then the remaining fields. Use the values you have, not a catalog average, unless that is all you know.
- 2Cost = linear ft × $/ft + fittings allowance for each material.
- 3Worked case: 60 ft run: PEX $1.2/ft vs copper $3.5/ft → ~$72 vs ~$210 materials.
- 4Buy materials after you walk the job. This is a first-pass quantity, not a purchase order.
Governing formula
Cost = linear ft × $/ft + fittings allowance for each material.
60 ft run: PEX $1.2/ft vs copper $3.5/ft → ~$72 vs ~$210 materials.
Example: set Linear feet = 60, PEX ($/ft) = 1.2, Copper ($/ft) = 3.5, then read the result.
