How to Estimate and Bid Paint Jobs
To estimate a paint job, calculate your variable costs (labor hours times labor rate, plus materials), then add markup to cover overhead and profit. Smaller companies should target at least a 30% margin after variable costs; larger companies at least 50%. Many painting contractors are concerned about estimating, and rightly so: price too high and you lose the job, too low and you lose money. This guide covers bidding residential interior and exterior work with an accurate, exact price, not a ballpark. These formulas have been used nationwide for over a decade by thousands of painters.
The Foundation: What Estimating Is Actually For
The purpose of estimating is not to win the job; that's the job of your sales process, reputation, and quality of work. The purpose of estimating is to come up with the correct price, which is a calculated number based on your variable costs, your overhead, and your target profit margin. Winning lots of jobs because you have the lowest price is not a great way to run a business.
- Variable costs: labor (total hours x labor rate) plus paint and supplies for the job.
- Fixed costs: marketing, office staff, warranty, website, accounting. Small companies have very little; larger companies have more.
- Profit: smaller companies should aim for no less than 30% margin after variable costs; larger companies no less than 50%.
Example: if labor plus materials will cost $1,000, a small company should bid at least $1,450 to cover insurance, warranty, marketing, accounting, and profit. A larger company should bid that same job around $2,000 to cover estimators, project managers, software, and hiring costs, plus profit. Bigger business, more costs, and more value delivered to justify the price.
When should you raise prices?
Aim for at least 20% net profit after all expenses. When you add overhead, raise prices slightly more than the new cost: if a new hire adds 7% of cost, raise prices 8%. One of the biggest mistakes in this industry is under-pricing jobs and working for too little. You are the business owner; you determine your pay.
How Do You Estimate Exterior Painting?
An exterior bid comes down to three inputs: total hours for prep work, total hours for application, and total material cost. Then:
- Total labor cost: total hours x labor rate. $20/hour is a safe nationwide starting point.
- Total material cost: gallons needed x price per gallon, plus sundries.
- Total job cost: labor + materials.
- Final price: job cost + your company markup for overhead and profit (see the margin guidance above).
Accurate prep and application hours require detailed standards based on what you're painting and its condition. Not all surfaces are equal: second-story trim takes longer, stucco takes longer, wood windows take longer. Break the job down in detail to get a consistent price that's fair to everyone. Our free estimating guide includes the full labor standards for prep hours, application hours, and materials.
How Do You Estimate Interior Painting?
Interior estimating is harder than exterior because more factors are involved, and almost every interior formula breaks down somewhere. Here's the simplest reliable method:
- Break the estimate into individual rooms. Draw a mini floor plan and list each room: kitchen, living room, dining room, hallway, bathroom, bedrooms.
- Estimate each room one at a time, working from a base price and adjusting up or down.
Our base price is a 10x12 bedroom with 8-foot ceilings and a normal amount of trim, two coats, labor plus materials included:
- Walls: $350–$400
- Trim: $100–$125
- Ceiling: $100–$125
- Total: $550–$650
If a room is bigger or has more trim, add to the base price; if smaller, take a little out. Then add the extras:
- Doors: $50 per door
- Closets: $50–$150 by size; treat a large walk-in as a small room
- Shelving: $10–$25 per shelf
- Prep: add time based on condition
- Moving furniture: $50 per hour, agreed with the homeowner
- Wall decorations: ask the homeowner to remove these
Worked example: three rooms
Using the 10x12 base standards on a real floor plan with an office, dining room, and living room, the total came to $2,135–$2,697:
- Office (121.9 sq ft, 1.5% larger than base): walls $355–$406, trim $102–$127, ceiling $102–$127, closet $50–$150, door $50. Total $659–$860
- Dining room (141.6 sq ft, 17% larger): walls $410–$469, trim $135–$169, ceiling $135–$169, closet $50–$150. Total $731–$957
- Living room (162 sq ft, 35% larger): walls $474–$541, trim $135–$170, ceiling $135–$170. Total $745–$880
Why You Shouldn't Bid Paint Jobs by Square Foot
Square-foot pricing is the most common approach in the industry, and it's a mistake. Imagine two 2,500 sq ft homes: they'll use about the same paint, but one has far more prep and trim detail than the other, and labor is where the money is. Bid by square foot and you'll underprice detailed houses and overprice simple ones. Estimating is a science, not an art, and per-square-foot pricing oversimplifies it.
Frequently Asked Questions
What profit margin should a painting company target?
At least 30% gross margin after variable costs for small companies, 50% for larger ones, and at least 20% net profit after all expenses.
What labor rate should I use in a painting estimate?
$20 per hour is a safe nationwide starting point; multiply by total prep and application hours to get labor cost.
How much should I charge to paint a standard room?
A 10x12 bedroom with 8-foot ceilings runs $550–$650 total with two coats: $350–$400 walls, $100–$125 trim, $100–$125 ceiling, labor and materials included.
What happens if I get an estimate wrong?
You'll mess up some estimates; everyone does. You have to price incredibly low to actually lose money on a job, so learn from each mistake, adjust your standards, and never make the same one twice.
