How to price a gutter job using your own costs

01Write the scope before you write a number

Decide what the job includes in one sentence a homeowner would understand: seamless 6-inch aluminum gutters on the whole roofline, four downspouts, tear-off of the old gutters, guard on the rear run. If the sentence has an “and maybe” in it, split it into an option with its own price. Scope creep starts on the estimate, not on the ladder.

02Count the quantities

Gutter feet per run, downspout feet per drop, the number of drops, inside and outside miters, end caps, and the footage of any guard or fascia. Walk the house and measure, or start from a roof outline and confirm each edge. Round runs up to the next foot. Downspouts are usually one to two feet longer than the wall height once you add the elbows.

03Material cost per foot

Take your supplier’s coil price and turn it into a per-foot figure, then add hangers, screws, sealant, and a waste allowance. Do the same for downspout, elbows, miters, end caps, outlets and guard. Materials move; update this table every time your supplier sends a new price sheet, not once a year.

04Labor cost per foot

Labor is where most rates go wrong because owners price their own time at zero. Use the loaded hourly cost of the crew (wages plus payroll taxes, workers’ comp, and any benefits), multiply by the hours a typical job takes including setup and cleanup, and divide by the footage. Keep a separate figure for second-story or steep-access work; it is not the same job.

05Job-specific costs

Dump fees for the old gutters, a permit if your town wants one, fuel and drive time, a lift rental, the rep’s commission. These belong on the job, not in overhead, because they change from job to job. Put them in as their own lines on the estimate so a discount never eats them by accident.

06Overhead

Rent, insurance, trucks, phones, software, the office, your own salary. Add it up for the year and divide by the number of jobs you actually complete, or by the feet you actually install. That gives you an overhead figure per job or per foot. If you do 300 jobs a year and overhead is $90,000, every job needs to carry $300 before you have made a dollar. Most contractors are shocked by this number the first time they run it, which is exactly why you should run it.

07Margin, not markup

Decide the margin you want on the price, then work backwards: price = cost ÷ (1 − margin). A 40% markup on cost is a 28.6% margin on price. If you want 40% margin, you need a 66.7% markup. Pick the margin that covers the slow season and the callback you will eventually eat. The profit calculator does this math and shows the formulas.

08A worked job, start to finish

Fictional single-story ranch, 148 feet of gutter, 42 feet of downspout in four drops, six miters, guard on the whole thing, old gutters removed.

Now turn that into per-foot rates for your pricebook so the next quote does not need a spreadsheet: on this example, once each line carries its share of overhead and margin, the gutter line (material plus install labor) works out to about $10.65 per foot, guard to about $19.45 per foot, and tear-off to about $2.25 per foot, with downspouts, miters, drops and fuel priced as their own lines. The estimate template on this site uses different made-up rates on purpose, so you can see the mechanics without mistaking either set for a market price.

09Final review before you hand it over

Read the estimate as the homeowner. Does every line say what it is and what it costs? Is the discount, if you gave one, applied after the job costs and not before? Is the deposit stated? Does the price still clear your margin after the commission? Three minutes here saves the call two weeks later where you explain why the number went up.
