Gutter installation cost calculator, by the foot and the drop
Installed 5 inch aluminum K-style gutter costs about $12.65 to $21.53 per foot in 2026 once downspouts, corners and labor are counted, against $3.75 to $5.80 a foot for the gutter metal alone. Enter gutter footage, downspout count and length, and the corners on your sketch, and this gutter cost calculator prices the trough, hidden hangers, pipe, elbows, miters, splash blocks and labor line by line. A 160 foot one-story job with four downspouts totals $2,024 to $3,445.
Worked example: 160 ft gutter length, 4 drops downspouts, 10 ft downspout length, 4 miters corners
That takes 80 hangers (Hidden hangers at 24 inches on center). National-average costs:
| Line | Quantity | Cost range |
|---|---|---|
| 5 inch K-style aluminum gutter | 160 ft | $600 to $928 |
| Hidden hangers | 160 ft | $304 to $472 |
| 2x3 downspout | 40 ft | $108 to $168 |
| Downspout elbows | 4 sets of 3 | $38 to $59 |
| Miters | 4 miters | $33 to $51 |
| Splash blocks | 4 blocks | $26 to $41 |
| Gutter hanging labor | 160 ft | $720 to $1,360 |
| Downspout labor | 4 drops | $140 to $280 |
| End caps, outlets, sealant, rivets and screws | 5% | $55 to $86 |
| Estimated total | $2,024 to $3,445 |
Enter the total gutter footage along the eaves, the number of downspouts and how long each one runs, and the corner count off your sketch. The interactive calculator on this page recomputes these numbers for your dimensions and adjusts for any US state.
How to measure for gutter work
List the runs, not just the total
Tape each fascia board that will carry gutter and list the runs by length. A 160 foot house could be four 40 foot runs or one 70 and three 30s, and the second layout needs more end caps and drops.
Count corners and drops on a sketch
Draw the roof from above. Each inside or outside corner is a miter, each open end is an end cap, and a downspout goes at a low end roughly every 40 feet of gutter.
Measure the drop height
Downspout length is roughly the eave height to the ground. A one-story eave around 10 feet takes about 10 feet of pipe per drop, and a two-story eave takes 20 or more.
Size it to the roof
A 2x3 downspout drains about 600 square feet of roof and a 3x4 about 1,200. Roof planes bigger than that, or steep ones that shoot water over the lip, are where 6 inch gutter earns its extra $1.50 a foot.
What this calculator assumes
- Costs are 2026 national averages for 5 inch aluminum K-style gutter formed on site and hung on a one-story house.
- Hangers go every 24 inches and are priced per foot of gutter. Each downspout gets three elbows and a splash block.
- Labor includes pulling and hauling the old gutter on standard one-story eaves.
- The 5 percent allowance covers end caps, outlets, sealant, rivets and screws.
- Fascia repair, gutter guards, underground drain tie-ins and second-story or steep-site premiums are not in the total.
- Gutter carries no waste factor because each run is rolled to its exact length.
Cost factors in gutter work
Second-story eaves
High runs need taller ladders, stabilizers and sometimes a lift, and they hang at a fraction of the one-story pace. Give them a separate labor line instead of averaging them into the ranch rate.
Gutter size and metal
6 inch K-style runs $5.05 to $7.85 a foot in material against $3.75 to $5.80 for 5 inch, and it pairs with 3x4 downspout. Heavier .032 coil stands up better to ladders and ice. Half-round and copper are different jobs at about 2.2 and 5.5 times the 5 inch price per foot.
Gutter guards
Guard adds $4.20 to $6.50 a foot in material, more than the 5 inch trough it covers. Quote it as its own line with its own labor so the gutter price still compares fairly against other bids.
Fascia and roof edge
Soft fascia will not hold a hanger. Replacing it is carpentry, and wrapping it in aluminum coil adds about $2.30 to $3.60 a foot in material before labor.
Where the water lands
A drop that dumps at the foundation is the first callback after a storm. Extensions at $9.50 to $14.75 or a tie-in to an underground drain cost more than a splash block but keep water away from the footing.
Frequently asked questions
How much does gutter installation cost per foot?
About $12.65 to $21.53 per foot for 5 inch aluminum K-style on a one-story house in 2026, downspouts included, on a 160 foot job with four drops. The trough and hangers alone are $5.65 to $8.75 a foot in material. The rest is downspout pipe, fittings, an allowance for small parts, and labor.
How many gutter hangers do I need?
One every 24 inches, so half the gutter footage: 80 hangers for 160 feet. Where snow and ice load the front edge, many installers tighten to 16 or 18 inches, which takes 120 or 107 hangers on the same run.
What does each added downspout cost?
On this calculator, one more 10 foot 2x3 drop with three elbows and a splash block moves the total by about $80 to $140: $42.95 to $66.90 in material, the 5 percent parts allowance on that, and $35 to $70 to install. A two-story drop doubles the pipe and adds ladder time.
Is 6 inch gutter worth the extra cost?
On big or steep roof planes, usually yes. 6 inch K-style costs about $1.50 a foot more than 5 inch in material and pairs with a 3x4 downspout, which drains about 1,200 square feet of roof against roughly 600 for a 2x3. That often means fewer drops on a long run.
What does Staxen cost for gutter installers?
It is $59 per month per AI employee, or $149 per month for all three, and the first 7 days are free in the app. Say the footage, corners and downspouts from the driveway and Eddie the Estimator prices the job line by line, then texts the homeowner a link to sign and pay the deposit.
