Free Painting Estimate Template (Excel, Google Sheets & PDF)
Interior painting prices off paintable square footage — walls and ceilings, measured after subtracting doors and windows — not floor area. A 5-room interior repaint (3 bedrooms, living room, dining room, two coats, trim included) runs about $4,605, or roughly $921 per room. Below is a free layout for Excel, Google Sheets, or PDF, plus that job broken down line by line.
Painting is the trade clients feel most entitled to negotiate, because the “materials” look cheap — a $45 can of paint covers a wall that took a day to prep and two coats to finish. A one-line quote (“Interior paint — $4,800”) reads like you’re charging for the gallons. A quote that separates prep, primer, paint gallons by coat, trim, and labor hours shows the client where the money actually goes, and that most of it is your time, not your Home Depot receipt.
What every painting estimate needs
Miss one of these and the client assumes you’re charging retail for a can of paint:
- Room list and paintable square footage — walls and ceilings separately, net of door/window area — not a vague “whole house.”
- Prep and surface repair as its own line — patching nail holes, caulking trim, sanding, protecting floors and furniture — since this is often 20–30% of total labor and completely invisible in the final photo.
- Primer, when needed — full coat vs. spot-priming repaired areas or stain-blocking — called out separately from finish paint.
- Coats specified — one vs. two — since it roughly doubles paint volume and application labor.
- Paint gallons by area — walls, ceiling, and trim often use different sheens and different paint, so price them on separate lines.
- Sundries — tape, plastic sheeting, caulk, brushes, rollers, sandpaper — a real cost that’s easy to under-bid if it’s not its own line.
- Application labor as hours, or a per-room / per-square-foot rate the client can compare across bids.
- What’s NOT included — furniture moving, wallpaper removal, ceiling texture repair — stated explicitly so it isn’t assumed free.
A real painting estimate, line by line (3-bedroom interior repaint)
Three bedrooms, a living room, and a dining room — about 3,200 sq ft of paintable wall and ceiling surface, two coats, trim included:
| Line item | Detail | Amount |
|---|---|---|
| Prep & surface repair | patch nail holes, caulk trim, sand, mask/protect floors | $440 |
| Primer | 2 gal, spot-prime repaired areas & stain-blocking | $64 |
| Wall & ceiling paint | 19 gal, 2 coats, ~3,200 sq ft @ 350 sq ft/gal/coat, eggshell walls/flat ceiling | $855 |
| Trim & door paint | 3 gal semi-gloss, baseboards, casing, doors | $156 |
| Sundries | tape, plastic sheeting, caulk, brushes/rollers, sandpaper | $180 |
| Application labor | 42 hrs (32 walls/ceiling + 10 trim) @ $55/hr | $2,310 |
| Subtotal | $4,005 | |
| Price @ ~15% margin | ÷ 0.87 | $4,605 |
That’s about $1.44/sq ft of paintable surface, or $921/room across the five rooms — a normal mid-range price for a full two-coat repaint with trim. Most painters ask for a modest deposit (10–20%, roughly $460–$920 here) to cover the paint order, with the balance due at the final walkthrough once the client has approved the finish in daylight.
Per-room vs. per-square-foot pricing
Small jobs (a single bedroom, a hallway) usually quote cleaner as a flat per-room price — easy for the client to compare and approve. Whole-house or open-concept jobs quote better per square foot of paintable surface, since “per room” breaks down once rooms flow into each other with no clear wall boundary. Either way, show your math (square footage, gallons, hours) underneath the flat number so it doesn’t read like a guess.

Paint grade, markup, and the coverage math that saves your margin
Coverage math is where painting bids quietly lose money: a gallon of quality paint covers about 350–400 sq ft per coat on primed drywall, but textured walls, dark color changes, or a third coat for full hide can drop that to 250–300 sq ft/gallon — buy short and you’re making an emergency paint-store run on your own dime mid-job. Most painters mark up paint 10–20% over what they pay at the counter to cover the trip and the account discount they’re not passing on to a retail client; keep that on the materials line, not folded into labor.
Color changes, extra coats, and getting the estimate signed
A dramatic color change (dark over white, or vice versa) commonly needs a third coat or a tinted primer — price that as an optional add-on line the client can accept or decline, rather than discovering it after two coats don’t fully cover. If the client changes colors mid-job after paint is already mixed, that’s a written change order, not a courtesy re-do. A signed estimate with a deposit line turns your quote into a job you can actually schedule paint and labor against.
Once the repaint above is done, bill it out with the matching Painting Invoice Template so the client sees the same rooms and coats they approved. Before you bid the next one, the Paint Calculator turns room dimensions into gallons and coats in seconds.
Frequently asked questions
How much does it cost to paint the interior of a house?
A 5-room interior repaint (3 bedrooms, living room, dining room, two coats, trim included) runs about $4,605, or roughly $921 per room and $1.44 per square foot of paintable surface. Color changes, textured walls, and extra coats push that higher.
Should I quote painting per room or per square foot?
Per room works cleanly for small, separate jobs like a single bedroom. Whole-house or open-concept jobs quote better per square foot of paintable wall and ceiling surface, since rooms without clear boundaries don’t divide evenly.
How much paint do I need per room?
Figure roughly 350–400 sq ft of coverage per gallon per coat on primed drywall. Textured surfaces, dark color changes, or a needed third coat can drop coverage to 250–300 sq ft per gallon.
What’s a fair markup on paint materials?
10 to 20% over counter cost is common, covering the supply run and the trade discount you’re not passing straight through to the client. Keep it on the materials line, separate from labor.
Do I need to charge extra for a dramatic color change?
Often yes. Going dark-over-light or light-over-dark can require a third coat or tinted primer for full hide. Price it as an optional line so the client agrees before you start, not after two coats don’t cover.
