Downspout cost calculator
Budget the downspouts: pipe by the linear foot plus elbows and fittings, from the prices you enter. A planning estimate, not a bid.
Calculator
3 downspouts of 20 ft at $6.00/ft plus 13 elbows is about $425.00. Enter your own prices — a planning estimate, not a bid.
Downspouts are the cheap part of a gutter job until the fitting count sneaks up. This adds the two lines that matter: pipe (downspouts × length × your $/ft) and elbows (count × your price each).
Every price is yours — off a real quote or store receipt. Nothing is hardcoded, so the number stays honest whatever prices do. The labeled band below is a sanity check, not a source of truth.
Pull your counts from the count & sizing and elbows & offsets tools, then price them here.
Formula
total = downspouts × length_ft × price_per_lf + elbows × price_per_elbow
Pipe cost plus fitting cost. Extensions and straps, if you buy them, add as more fittings.
Worked example
3 downspouts, 20 ft each at $6/ft, plus 13 elbows at $5:
Pipe: 3 × 20 × $6 = $360. Elbows: 13 × $5 = $65. Total = $425.
Copper or 3×4 aluminum runs higher per foot; drop your real numbers in and the total follows.
What this covers (and what it doesn’t)
Length ≈ wall height. A downspout drops eave to grade, so a two-story run is roughly double a single-story one — and adds height/access to any labor line.
Count fittings honestly. Elbows, offsets, straps and any extension pieces all cost money; the elbows & offsets calculator gets the elbow number right.
Material moves the price. Aluminum is the value default; copper is a premium look at a premium per-foot rate. Enter whichever you are actually buying.
This is a materials planning estimate for the downspouts only — not labor, not a full install. For the whole job, use the gutter installation cost tool. Get itemized written quotes from licensed, insured contractors before you commit.

| Item | Typical installed |
|---|---|
| Downspout pipe (aluminum, per linear foot) | $5.00–$12.00/ft |
| Elbow / fitting (each) | ~$3–12 |
Copper and larger 3×4 outlets run higher. Bands vary by material, size, height and local labor — get itemized written quotes.
