Paint Calculator Canada 2026
Our free paint calculator instantly works out how much paint, primer, and labour your project needs anywhere in Canada, with 2026 pricing built in for every province and territory. Enter a room or a full takeoff, pick interior or exterior, and get litres, cans, and a dollar total in seconds. Updated for current paint prices, labour rates, and the latest provincial sales tax, the paint calculator gives homeowners and contractors a real number to plan around, not a rough guess.

How Our Paint Calculator Works
The tool runs the same math a professional estimator runs, just faster. Four steps and you've got your answer.
Enter Your Area, or Let It Measure for You
Start with the surface you're painting. Type the room length, width, and height, plus the doors and windows to deduct, and the paint calculator works out the paintable area for you. Already pulled the square footage off a takeoff? Switch to "I know my area" and type it straight in.
Here's the thing about area: paint covers walls, not floors. A 12 by 12 foot room with 8-foot ceilings has about 384 square feet of wall, not 144. That's the number that drives everything, and it's the one most people get wrong.
Your Province Sets the Price
Choose your province first, because location moves the total more than almost anything else. The paint calculator pulls your local labour rate and the correct 2026 sales tax the moment you select it.
Each region prices differently. British Columbia sits high because WorkSafeBC rules on multi-storey work and heavy coastal rain that demands moisture-resistant coatings both push costs up. Alberta runs leaner, with deep skilled labour and the lowest tax in the country at 5 percent. Ontario lands in the middle. The calculator handles these gaps so a painting cost calculator search in Ontario, Alberta, or anywhere else lands on the right figure.
Pick Interior, Exterior, and Your Coats
Choose interior or exterior, because it changes both the surfaces and the coverage. Interior gives you walls and ceilings on smooth, lightly textured, or knockdown finishes. Exterior gives you siding, soffits, and substrates like wood, fibre cement, vinyl, stucco, and brick.
Then set your coats. Two is standard for an even, lasting finish, so the tool defaults to two. Exterior paint spreads thinner and almost always needs two coats to hold up against weather. Going light over dark, or dark over white? You're looking at a primer coat first.
Dial In Prep, Primer, and Markup
Last step is the detail that separates a real estimate from a guess. Set your prep level, toggle primer, choose a paint quality tier, and the result updates live.
Prep is the quiet cost driver. A wall in good shape needs light prep. An older surface with patching, caulking, and sanding adds 10 to 25 percent to labour time, and the calculator reflects that in the prep setting. Contractors get extra controls too: trim by linear foot, per-door pricing, a minimum job fee, and a markup field that turns cost into a bid price.
Now Come to the Results
Here's where your money goes. The paint calculator splits the total into the same lines a professional estimate carries, so nothing hides.
Paint and Primer
Paint volume comes from your area, your coats, and the coverage rate. Manufacturer data sheets from Benjamin Moore and Behr list 350 to 400 square feet per gallon on one coat, or about 10 square metres per litre on smooth interior walls. Exterior drops to 8 to 10 square metres per litre on smooth siding, and as low as 4 to 6 on stucco or rough masonry.
Primer counts on its own line because it covers and costs differently than topcoat. The tool prices it at about 11 square metres per litre for one coat and rounds everything to real Canadian can sizes: 946 mL, 3.78 L, and 18.9 L. No half-cans, no guessing what to buy.
Labour: Where Most of the Money Goes
Labour is the big number. In 2026, Canadian painters charge 40 to 90 dollars an hour, and a skilled painter covers 100 to 120 square feet of flat wall per hour. That's why labour eats 60 to 85 percent of a typical bill while the paint itself is a small slice.
The calculator prices labour two ways: by hourly production rate, or by square foot of painted surface. Pick whichever matches how you quote. Homeowners painting it themselves flip on the DIY option, which drops labour and shows just paint and supplies.
Supplies and Prep
The small stuff adds up. Tape, drop cloths, roller covers, brushes, and caulk all land on the supplies line, and prep work scales your labour up or down based on the wall's condition. Skip these and your estimate comes in light every time.
Sales Tax by Province
Tax changes the second you cross a provincial line, so the calculator applies your local rate to the total. Alberta sits at 5 percent. Ontario is 13 percent. New Brunswick, Newfoundland and Labrador, and Prince Edward Island all charge 15 percent. The result is a number that matches what you'd actually pay where you live.
Paint Quality Levels Explained
Paint quality changes the price per gallon and how many coats you need. Pick the tier that fits the job, then let the paint calculator price it.
- Coverage: 350 to 400 sq ft per gallon, one coat
- Coats: Usually 2 to 3, since hide is thinner
- Best for: Rentals, flips, ceilings, low-traffic rooms
- Trade-off: More coats and shorter lifespan than premium
- Coverage: 350 to 400 sq ft per gallon, one coat
- Coats: 2 for most colour changes
- Best for: Living rooms, bedrooms, hallways, most repaints
- Trade-off: None major; the practical everyday pick
- Coverage: 400 sq ft per gallon, often fewer coats
- Coats: 1 to 2 on many colours
- Best for: High-traffic areas, bold colour changes, trim, cabinets
- Trade-off: Higher upfront cost, lower labour over its life
Common Mistakes That Blow Your Paint Budget
We work with homeowners, painting contractors, and subcontractors, and the same mistakes show up again and again. Here's what catches people.
Measuring the Floor Instead of the Walls
The biggest one. Floor area and wall area are different numbers, and paint covers walls. That 12 by 12 room has 144 square feet of floor but close to 384 of wall. Price off the floor and you'll buy half the paint you need.
Forgetting the Second Coat
One coat rarely covers. Most walls need two for an even finish, which doubles your paint from the single-coat figure. Dark-to-light changes need it most. The calculator defaults to two coats so your number matches the wall.
Skipping Primer and Prep
Bare drywall, fresh patches, stains, and big colour changes all need primer first. Skip it and the topcoat spreads thin, soaks in, and costs you an extra coat anyway. Prep is the same story: cracks, caulking, and sanding take time, and that time is real money on the labour line.
Ignoring Seasonal Pricing
Timing moves the bill. Winter slows exterior work and tightens crew availability, while spring brings the material price bump that comes with peak demand. A quote written in February prices differently than the same job in May, so adjust your paint price and labour rate to the season you're bidding.
Paint Cost by Province in 2026
Painting costs change with your province, and so does the paint calculator. Labour markets, climate, and tax all shift the total, which is why the same job prices higher in Vancouver than in a small Alberta town. The tool fills in your provincial rate and tax automatically.
| Province / Territory | 2026 sales tax | Painter rate (per hour) | Interior cost (per sq ft, floor) |
|---|---|---|---|
| Ontario | 13% | $55 to $85 | $2.00 to $5.00 |
| Alberta | 5% | $50 to $75 | $1.80 to $4.00 |
| British Columbia | 12% | $60 to $90 | $2.50 to $5.00 |
| Quebec | 14.975% | $45 to $70 | $1.80 to $3.50 |
| Manitoba | 12% | $45 to $70 | $1.80 to $3.50 |
| Saskatchewan | 11% | $45 to $70 | $1.80 to $3.50 |
| Nova Scotia | 14% | $40 to $65 | $1.75 to $3.25 |
| New Brunswick | 15% | $40 to $65 | $1.75 to $3.25 |
| Newfoundland & Labrador | 15% | $45 to $70 | $1.80 to $3.50 |
| Prince Edward Island | 15% | $40 to $60 | $1.75 to $3.00 |
| Yukon, NWT, Nunavut | 5% | $70 to $120 | $3.00 to $7.00 |
A single room runs $400 to $900 across most of the country. A full 1,500 square foot home interior runs $4,000 to $7,000 in 2026, including labour, paint, and standard prep. These are the same provincial inputs Blaze Estimating uses on live bids, and the same logic behind our broader construction cost calculator.
2026 Paint Market Update
Three things shifted the 2026 market, and they matter before you price a job.
Material Prices
Premium products held firm, with top exterior paints running 80 to 120 dollars a unit through national distributors. Standard interior lines sit at $60 to $80 a gallon, and contractor grade at $40 to $55. Material is rarely the budget breaker; it's a fraction of the total next to labour.
Labour and Availability
Labour stayed tight, which kept rates firm across most provinces. A painter still covers 100 to 120 square feet of flat wall per hour, so a whole-house repaint with two coats and ceilings runs into real crew time. That's the line to watch on any 2026 estimate.
What Changed This Year
One tax rule moved. Nova Scotia cut its HST from 15 to 14 percent, effective April 1, 2025, the first change there in years. The paint calculator already reflects the new rate, so estimates for Nova Scotia projects come out correct without a manual fix.
Frequently Asked Questions
How much paint do I need for a room?
Measure the wall area (room perimeter times ceiling height), subtract the doors and windows, then divide by 350 to 400 square feet per gallon and multiply by your coats. A standard 12 by 12 foot room with 8-foot walls needs about two gallons for two coats. The paint calculator above does this for you the moment you enter the dimensions.
How many gallons of paint for a 12 by 12 room?
A 12 by 12 foot room with 8-foot ceilings has roughly 384 square feet of wall, which takes about two gallons for two coats. Add the ceiling and you need close to half a gallon more. A big colour change pushes you toward a primer coat as well.
How much does it cost to paint a house in Canada in 2026?
A 1,500 to 2,000 square foot home interior costs $4,000 to $7,000 in 2026, including labour, paint, and standard prep. Exterior repaints run higher, often $4,000 to $18,000 depending on size, condition, and province. Labour drives most of that total. Want a firm number for your home? Run it through the paint calculator with your province selected.
How much does interior painting cost per square foot in Canada?
Interior painting runs $1.80 to $5.00 per square foot of floor area in 2026, with whole-house jobs at the low end and single rooms at the high end. Single rooms cost more per foot because setup and cleanup take the same time on a small room as a large one. Toronto and Vancouver sit near the top of that range.
Is the paint cost calculator accurate for Ontario, Alberta, and BC?
Yes. The paint calculator carries 2026 labour rates and sales tax for all 13 provinces and territories, so the total reflects your exact location. Ontario applies a 13 percent tax, Alberta 5 percent, and British Columbia 12 percent with higher coastal labour. Every rate stays editable when your local quotes differ.
Do I need primer, and does it change how much paint I buy?
Use primer on bare drywall, fresh patches, stained surfaces, or any big colour change. Primer seals the surface so the topcoat spreads further, which lowers the paint you buy on the finish coats. The calculator counts primer separately, at about 11 square metres per litre for one coat, and prices it on its own line.
How much paint do I need for two coats?
Double the single-coat amount. If one coat needs one gallon for 384 square feet, two coats need about two gallons. Two coats is the standard for an even, durable finish, which is why the paint calculator defaults to two.
What's included in a professional painting estimate?
A professional painting estimate itemizes paint, primer, supplies, labour by surface, prep, trim and doors, and tax, then adds the contractor's markup. The calculator builds the same structure, which makes it easy to check a quote line by line.
