Whole house paint calculator
Repainting a whole house? Rough math: a 2,000 sq ft home needs ~12 gallons interior + ~8 gallons exterior + 2 gallons trim — about $1,200 in paint at premium prices. Use the inputs below for a more precise estimate; we'll bundle Kompozit ONE for interior, PRO for exterior, and PRO Semi-Gloss for trim.
Estimates round up to the nearest quart and are based on Kompozit's published coverage. Buy slightly more for touch-ups and color changes.
Quick reference numbers
- 1,000 sq ft home: ~6 gal interior + ~4 gal exterior + ~1 gal trim
- 2,000 sq ft home: ~12 gal interior + ~8 gal exterior + ~2 gal trim
- 3,000 sq ft home: ~18 gal interior + ~12 gal exterior + ~3 gal trim
Phasing the work
Don't try to do interior + exterior simultaneously. Most homeowners do exterior in summer (paint needs 50°F+ for several hours), interior any time. Spread the cost over a season if you're DIY; a contractor will compress it to ~2 weeks.
FAQ
Yes if it's rated for both — Kompozit ONE and PRO are interior/exterior. Buying one product instead of two simplifies inventory and lets you use leftovers across surfaces.
Solo DIY: 4–6 weekends. Two people: 2–3 weekends. Pro crew: 5–10 days for a 2,000 sq ft house including prep.
