How much does it cost to hire a contractor to finish a basement?
Labor to finish a basement runs $6 to $20 per square foot, or 20% to 40% of the total cost, on HomeGuide's published figures.
That is the number the cost guides bury, because they answer the total and this question is about the contractor's half of it. HomeGuide puts basement finishing labor at $6 to $20 per square foot, $3,000 to $30,000 in total, or 20% to 40% of the whole project. On top of that a general contractor charges $50 to $150 per hour, or 10% to 20% of construction costs, to coordinate the subcontractors and run the job.

This page is general information, not professional advice. Remodeling prices move with your local labor market, the condition of what is already there and what your building department requires, and the only number that counts is a written quote from a contractor who has walked the job.
What the whole job costs, so the share means something
HomeGuide publishes $30 to $50 per square foot to finish a basement, or $15,000 to $75,000 total for 500 to 1,500 square feet. Partially finishing one runs $2,500 to $20,000. Take its own 20% to 40% labor share against that and the contractor's portion of a mid-sized finish is a five-figure line inside a five-figure job — which is why the split is worth asking a bidder to show you.

How much does it cost to finish a basement of 2,000 square feet?
| Basement size | Open plan | Three rooms |
|---|---|---|
| 500 sq ft | $15,000 – $20,000 | $20,000 – $25,000 |
| 800 sq ft | $24,000 – $32,000 | $32,000 – $40,000 |
| 1,000 sq ft | $30,000 – $40,000 | $40,000 – $50,000 |
| 1,500 sq ft | $45,000 – $60,000 | $60,000 – $75,000 |
| 2,000 sq ft | $60,000 – $80,000 | $80,000 – $100,000 |

So a 2,000-square-foot basement is $60,000 to $80,000 open-plan and $80,000 to $100,000 divided into three rooms on HomeGuide's table, and the labor inside that is its $6 to $20 per square foot. The gap between the two columns is the walls: HomeGuide's own note is that an open floor plan saves on lumber, drywall and insulation.

Which specialists the contractor is paying
HomeGuide lists them with their own rates, and this is the useful part of a quote to read line by line. An architect charges $100 to $250 per hour for layout and structural design. A structural engineer charges $100 to $220 per hour, or 1% to 5% of the cost, where the work touches what holds the house up. An electrician charges $50 to $130 per hour, and wiring runs $4 to $9 per square foot with labor. A plumber charges $45 to $150 per hour, and new plumbing runs $450 to $1,800 per fixture. The finishing permit is $200 to $1,000, or 1% to 2% of the total.

Ask a bidder to separate labor from materials on the estimate. If the two are welded into one number, there is nothing in the quote you can compare against the next one.
What a contractor is worth on this particular job
A basement is the room where the building code has the most to say. HomeGuide notes that a basement ceiling has to be at least 7 feet, that a room needs a window, a closet and a door to count as a bedroom, that every basement living area needs an egress window or emergency exit at $2,000 to $5,000 installed, and that a finished basement must be heated for its square footage to count toward the home's living space at all. Its guidance is that permits are required for structural changes and that finishing without one can affect resale.
