900 sq ft rec room
No bath, no egress, framing included, mid tier.
Often $50–$90/sf all-in — planner totals align with mid-five figures. Moisture line is mandatory before drywall.

Questions for contractors
- Moisture management plan before drywall?
- Egress designed for bedroom use?
- Return air path for HVAC comfort?
- Who handles radon retest after finish?
Quick answer
Finishing a basement commonly runs about $50–$90 per square foot all-in for mid-range LVP, lighting, and framing — more with egress windows, rough-in or full baths, and moisture remediation. Enter finish area and scope for budget line items, MEP trade order, and moisture-first checklist items.

Understanding the result
How to use this
Finish area, bath and egress scope → line-item budget, MEP sequence and hidden moisture costs.
How the math works
Finish square footage, bath scope, egress, ceiling mitigation, and finish tier scale moisture prep, framing, MEP, drywall, flooring, and permits. The model assumes you fix moisture before aesthetics — line items reflect that order, not a cosmetic-only finish.
Where to find each input
- Finish sq ft — measure interior perimeter minus utilities; do not include unfinished crawl
- Bath scope — rough-in vs full finish changes plumbing and permit set
- Egress — required for sleeping rooms; IRC clear opening dimensions on plans
- Ceiling — note beams below 7 ft clear; soffits add drywall labor
- Location factor — labor-heavy finish trades vary by metro
Worked examples
1,000 sq ft with egress bedroom
Egress window, rough-in bath, LVP, mid tier.
Egress and bath jump MEP and permit weeks. Verify AFCI/GFCI and emergency escape inspection sequence.
1,200 sq ft full bath
Full bath, egress, low ceiling soffits, premium tier.
Pushes toward upper five or six figures. Panel and radon retest after enclosure are common add-ons.
What this does not include
- Exterior foundation waterproofing mega-projects
- Walk-out door excavation
- Kitchenette gas line
- Soundproofing cinema build-outs
- Furniture and AV
Regional adjustment
Frost and water-table markets drive exterior waterproofing before finish. Radon zones (Upper Midwest, Rockies) often need mitigation after enclosure. Labor indices swing finish cost 25–40% between coasts and smaller metros.
Accuracy and references
Cost per square foot bands align with RSMeans basement finish medians and IRC egress/window well requirements for sleeping rooms. Moisture management precedes fiberglass or drywall per building science best practice.

Is this free?
Yes — runs in your browser, no account required.
Can I finish a damp basement?
Only after fixing the source — finishing over seepage guarantees mold failure.
Do I need a permit?
Yes for framing, electrical, plumbing, HVAC changes, and egress — cosmetic paint alone may not.
What ceiling height is required?
Often 7 ft clear in habitable rooms — local code may be stricter.
Is egress required?
For bedrooms below grade — emergency escape opening with sized well.
LVP or carpet?
LVP tolerates minor moisture swings; planner assumes hard-surface friendly finish.
How long does it take?
6–14 weeks typical with MEP and inspections — longer with exterior waterproofing.
Will taxes go up?
Assessors may add finished sq ft — varies by jurisdiction.
Rough-in vs full bath?
Rough-in is stub and drain; full includes fixtures, tile, and vent fan.
What is the biggest overrun?
Moisture remediation and panel upgrades discovered after layout.
Can I DIY part?
Turn off labor toggle to see material-heavy share — MEP usually requires licensed trades.
