This calculator vs. a flat $8/ft leaf-filter special
Gutter-guard shops are shopped against a flat $8-a-foot leaf-filter special. That rate cannot see the job — stories, miters, extra downspouts, a clean-first pass through packed gutters, and fascia repair decide whether the footage pays, and two runs of the same length can differ by thousands of dollars in real cost.
What a flat $8/ft special is
A price per foot is the fastest number to advertise on a postcard or a coupon page: measure the run, multiply by a rate, read back a total. It is also the unit homeowners already bring with them when they call for a quote.
The rate was priced from a specific job — typically a one-story ranch with a clean, empty run and a handful of corners — and then reused for the next lineal-foot number that calls in, whether or not that next job shares any of those.
What this calculator is
This page keeps no account and sends nothing to a server. You enter lineal feet of gutter, stories, miters, extra downspouts, system type — screen, foam, reverse-curve, or micromesh — whether the gutters need a clean-first pass, fascia repair feet, occupied-home access, and steep-roof access, plus your own wage, payroll burden, travel and equipment, overhead, and target margin. It prices access hours, miters, downspouts, clean-first, and fascia separately — for this job, not a rate carried over from the last one.
| What a flat $8/ft rate does | What this calculator does instead |
|---|---|
| Charges the same $8/ft for a one-story ranch with empty gutters and a two-story colonial with packed gutters and rotten fascia, even though stories and prep are where the extra hours live. | Prices extra stories, a clean-first pass, and fascia repair as their own line items, so a harder job costs more without anyone eyeballing a surcharge. |
| Has no line for miters or extra downspouts — a run of four corners and a run of twelve get the same rate. | Prices miters and downspouts above the included count as their own hours and hardware. |
| Has no line for system type — a $2.25/ft screen coil and an $8.50/ft micromesh coil get quoted the same. | Prices coil or mesh material per foot by system type: screen, foam, reverse-curve, or micromesh. |
| Bundles clean-first and fascia repair inside the same blended per-foot number, if the crew notices them at all before quoting. | Nets clean-first hours and fascia repair hours and material out as their own lines, priced only when the job needs them. |
| Gives the crew a number to quote, not a number to check a quote against. | Reports the price per foot and the walk-away price alongside the total, so a shopped rate can be scored against real cost before you match it. |
Same $8/ft rate, two different jobs
Using this calculator's own shipped cost inputs — $36 hourly wage, 32% burden, $45 travel and equipment, 16% overhead, 28% target margin, 120 ft / 1 story / 4 miters / 3 downspouts included:
A 140 ft one-story ranch with empty gutters, 4 miters, no extra downspouts, and no fascia repair — close to the job an $8/ft special is shopped from — takes 2.7 crew-hours and prices at $786.71 for the job — $5.62 a foot, already under the flat special.
Bid a 220 ft two-story colonial instead — micromesh, 12 miters, 2 extra downspouts, a clean-first pass through packed gutters, and 16 ft of fascia repair — and it takes 15.3 crew-hours, costs $3,313.08 to run before a dollar of profit, and this calculator prices it at $4,601.50 — $20.92 a foot. Quoting that job at the flat $8/ft special reproduces $1,760.00 for 220 feet, which is $1,553.08 below the job's own break-even cost — before counting the $2,841.50 it falls short of this calculator's own price at a 28% target margin. Same advertised rate, one job that pays and one that loses money before the truck leaves.
Common questions
Why does a flat $8/ft leaf-filter special get a gutter-guard bid wrong?
Because lineal feet alone does not measure the job. A 140 ft one-story ranch with empty gutters -- close to the job the $8/ft special is shopped from -- takes about 2.7 crew-hours and this calculator prices it at $786.71, or $5.62 a foot, already under the flat special. The same $8/ft rate applied to a 220 ft two-story colonial with 12 miters, 2 extra downspouts, a clean-first pass through packed gutters, and 16 ft of fascia repair reproduces a $1,760.00 quote, on a job this calculator prices at $4,601.50 and that costs $3,313.08 to run before a dollar of profit -- so the flat rate does not just thin the margin, it quotes $1,553.08 under break-even.
What does a flat per-foot rate usually miss entirely?
Stories, miters, extra downspouts, whether the gutters need to be cleaned out before the guard goes on, and fascia condition. A flat rate has no line for a second story's ladder and staging time, no line for eight extra miters over the four a ranch run already includes, no line for two extra downspouts, no line for clearing a fall's worth of packed leaves first, and no line for rotten fascia that has to be replaced before anything can be hung.
How big is the pricing gap in practice?
Using this calculator's own shipped cost inputs: a 140 ft one-story ranch with empty gutters, 4 miters, no extra downspouts, and no fascia repair takes 2.7 crew-hours and prices at $786.71 -- $5.62 a foot, already under the $8 special. A 220 ft two-story colonial with 12 miters, 2 extra downspouts, a clean-first pass through packed gutters, and 16 ft of fascia repair takes 15.3 crew-hours, costs $3,313.08 to run before a dollar of profit, and this calculator prices it at $4,601.50 -- $20.92 a foot. Quoting that job at the flat $8/ft special reproduces $1,760.00 for 220 feet, which is $1,553.08 below the job's own break-even cost -- before counting the $2,841.50 it falls short of this calculator's own price at a 28% target margin.
Is a flat per-foot rate ever a reasonable shorthand?
For a narrow band of similar jobs -- one story, a handful of miters, empty gutters, sound fascia, the same system the rate was learned on -- a per-foot number can land close. The risk is quoting a two-story job, a packed clean-first, or rotten fascia the same way sight unseen, because the rate does not know the stories, the miters, or the fascia condition until the crew is on the roof, and by then the per-foot number has often already been quoted.
Does this calculator know my local labor rates or material costs?
No. It has no data on your local labor market or your supplier's coil and mesh pricing. It takes lineal feet, stories, miters, extra downspouts, system type, a clean-first pass, fascia repair, occupancy, and roof pitch, plus your own wage, payroll burden, travel and equipment, overhead, and target margin, and turns that into install hours and a price for this job -- the arithmetic a flat per-foot rate skips, not a market survey.
