New gutters are priced per linear foot of eave, and this calculator estimates that footage from house size — 180 feet for a medium home. In k-style aluminium with no guards that comes to $1,450–$2,950 installed, of which labour is $270–$540 and a downspout allowance is a flat $100–$250.
Profile does not change the estimate
This calculator does not model a price difference by gutter profile. Its profile multiplier is 1.0 for k-style, half-round and fascia alike, so the three return the same figure for a given material and home size. Published estimates of a price difference by style disagree with each other by a wide margin and none traces to a manufacturer price list or trade association, so no per-style figure is modelled.
Treat that as a floor on a half-round job. Half-round gutter takes longer to hang than k-style — it needs different brackets and it is less forgiving on a wavy fascia — and neither the material nor the labour line here reflects that. Get a style-specific quote from a local installer.
Profile is also not purely cosmetic. K-style holds appreciably more water per inch of face height than half-round of the same nominal size, which is why it dominates on new build. Half-round is chosen for period-correct appearance, so it suits older and historic houses whose architecture it matches and looks out of place on most new builds.
The labour band is the part that travels least well between markets. The Bureau of Labor Statistics reports 124,600 of the 135,490 US roofers (SOC 47-2181) working in foundation, structure and building exterior contracting — the trade that hangs gutters — at a May 2025 mean hourly wage of $27.95 and a 10th-to-90th-percentile spread of $18.01 to $39.29. On a job where labour is a fifth or less of the total, that spread moves the bottom line less than it does on a repair or a cleaning contract, which is why installation quotes cluster more tightly than service quotes do.
Methodology
Linear footage by house size, per-foot material rates by material, the profile multiplier (1.0 for every style — no per-style price difference is modelled, because no primary source for one was found), the $1.50–$3.00 per foot labour band, the guard rates and the flat downspout allowance are the constants held in this calculator's own module, and every figure above is computed from them.
