Interior Painting Budget: Paint, Supplies, Prep and Labor
Paint is often a smaller share of a painting project’s cost than people expect. Rollers, brushes, tape, patching compound and drop cloths add up, and if you hire a painter, labor typically dwarfs materials. This guide lists every cost so your budget is complete, whether you paint yourself or get quotes.
1. Paint and primer
Start with quantity. The Interior Paint Calculator gives you gallons for walls, ceiling and primer. Then decide on quality: higher-priced lines typically offer better hide, washability and durability, which can mean fewer coats. Price the actual product you’ll buy rather than an average.
Sheen matters for budget too. Flat and matte finishes hide wall imperfections; eggshell, satin and semi-gloss are easier to clean and are common in kitchens, bathrooms and trim. Trim paint is a separate purchase.
2. Supplies checklist
If you’re starting without any painting gear, here is what a typical room calls for. Many items are reusable across rooms.
| Item | Notes |
|---|---|
| Roller frame and covers | Nap length depends on texture: shorter for smooth walls, longer for textured. |
| Angled sash brush | For cutting in along ceilings, corners and trim. |
| Paint tray and liners, or a bucket and grid | A bucket and grid is faster for large rooms. |
| Extension pole | Makes ceilings and tall walls safer and faster. |
| Painter’s tape | Optional if you cut in freehand. |
| Drop cloths | Canvas is reusable; plastic is cheaper but slippery. |
| Patching compound, putty knife, sanding sponge | For nail holes and dings. |
| Caulk and caulk gun | For gaps between trim and wall. |
| Step ladder | Most rooms need one. |
| Rags, cleaner, stir sticks, can opener | Cheap but easy to forget. |
Enter the total in the calculator’s supplies field. Tax is applied to paint and supplies together.
3. Prep and repairs
Good paint jobs are mostly prep. Budget time and materials for washing walls (especially kitchens), filling holes, sanding patches, spot-priming repairs, and removing outlet covers. If walls have water stains or peeling paint, find the cause first; repainting over a moisture problem won’t last.
If your home was built before 1978, existing paint may contain lead. Sanding or scraping it can create hazardous dust. In that case, test before you disturb any paint, and if you hire someone, the U.S. EPA requires contractors working on pre-1978 homes to be certified in lead-safe practices.
4. Labor, if you hire it
Painters may quote per square foot of wall, per room, or as a flat project price. Whichever way they quote, ask what’s included so quotes are comparable:
- Are paint and supplies included, or billed separately? Whose brand and product line?
- How many coats are included?
- Is wall repair and patching included, and how much?
- Are ceilings, trim, doors and closets included?
- Will they move furniture and cover floors?
- Are they insured, and do they offer a workmanship guarantee?
The calculator accepts either a per-square-foot rate or a flat quote, so you can test different quotes against the same room.
5. DIY vs. hiring: the honest trade-off
Doing it yourself saves the labor cost, but it costs time, and the first room often takes longer than expected while you learn cutting in. Ceilings, stairwells and tall walls are where many homeowners decide a professional is worth it. A middle path is to do the prep yourself and hire out the painting, or the reverse. Get the number for each scenario before you decide.
6. A small contingency
A modest buffer covers an extra gallon, a second roller cover, or a repair you didn’t see until the furniture moved. Keep it separate so you can tell when you’ve used it.
