How to use the sump pump cost calculator
- Choose new install or replacement. New install uses three independent averages. Replacement in an existing pit uses two sources and is disclosed as n = 2.
- Optionally add a battery backup as a Fixr add-on price of $150–$250 (install labor may be extra) or as Angi $1,000–$2,000 installed. Those figures are not blended into one line.

How the typicals are built
New-install typical $1,400 is the median of HomeGuide $1,600, Fixr $1,400 and Angi $1,100. The displayed range $600–$2,500 follows HomeGuide’s published installed band. Replacement typical $612.50 is the median of HomeGuide $400–$700 (mid $550) and Fixr $350–$1,000 (mid $675), range $350–$1,000, disclosed as n = 2. This Old House and Bob Vila derive from Fixr or Angi and are not counted. HomeAdvisor is the same company as Angi and is counted once.
Worked examples
A new install with no backup has a typical of $1,400 ($600–$2,500). Adding the Fixr battery add-on at the $200 midpoint brings the typical to $1,600 (the battery line is Fixr’s add-on price; install labor may be extra). A replacement with no backup has a typical of $612.50 ($350–$1,000).
Sources & assumptions
How this calculator gets its numbers. Full method: our methodology.
- New-install typical is the median of three independent published averages: HomeGuide $1,600, Fixr $1,400, Angi $1,100 → $1,400. Displayed range $600–$2,500 follows HomeGuide’s published installed band.
- Replacement in an existing pit is n = 2: HomeGuide $400–$700 (mid $550) and Fixr $350–$1,000 (mid $675); typical $612.50; range $350–$1,000. Disclosed as two sources.
- This Old House and Bob Vila derive from Fixr or Angi and are not counted. HomeAdvisor is the same company as Angi and is counted once.
- Battery backup is exposed as two optional add-ons because published figures conflict: a Fixr add-on price of $150–$250 (mid $200; install labor may be extra) versus Angi $1,000–$2,000 installed (mid $1,500). HomeGuide’s $150–$800 is for a whole battery-powered sump pump and is not used.

- HomeGuide, Sump Pump Installation Cost. Installed $600–$2,500, average $1,600. Replacement $400–$700. Battery-powered sump pump (whole pump, unit only) $150–$800 — a different item from a backup add-on, not used for the battery line.
- Fixr, Sump Pump Installation Cost. Average $1,400; $800–$2,000 typical band. Replacement $350–$1,000. “Adding battery backup to a sump pump costs $150 to $250” — used for the Fixr battery add-on line.
- Angi, Sump Pump Installation Cost. Updated Oct 5, 2026: average $1,100; most $800–$1,500. Battery backup add-on $1,000–$2,000 installed.

Frequently asked questions
How much does a new sump pump install cost?
The three-source typical is $1,400, in a $600–$2,500 range. A written local bid wins.
How much to replace a sump pump in an existing pit?
The two-source typical is $612.50, in a $350–$1,000 range, disclosed as n = 2.
Why are there two battery backup options?
Published figures conflict: Fixr puts adding a battery backup at $150–$250 (install labor may be extra), while Angi puts an installed add-on at $1,000–$2,000. (HomeGuide’s $150–$800 is for a whole battery-powered sump pump and is not used.) The page keeps them as two optional add-ons rather than blending them.
Are This Old House and Bob Vila counted?
