Painting Estimate Calculator for Painting Contractors

Built for painters pricing a job. Add each room's length, width and height, deduct doors and windows, choose coats and whether ceilings are included, and set your own coverage, paint and primer prices, prep hours, production rate, labour rate and materials markup. You get the paint quantity, labour hours, materials, labour and total, and a printable estimate. Every rate is editable because it depends on your crew, your paint and your market. Everything runs in your browser. Nothing you type is sent to We.Inc or anyone else.

How it works

  1. Choose feet and gallons or metres and litres. Defaults change to match, and every number stays editable.
  2. Add each room: length, width and wall height, plus how many doors and windows to deduct. Tick ceiling if you are painting it.
  3. Set coats, coverage per gallon or litre (check the product's data sheet), paint price, and whether the job needs a primer coat and at what coverage and price.
  4. Enter prep hours (masking, filling, sanding, moving furniture), your production rate (area painted per hour per coat) and your labour rate.
  5. Add a markup on materials and any sundries (tape, plastic, caulk). The calculator rounds paint up to whole containers.
  6. Read gallons or litres, labour hours, materials, labour and total, then print the estimate or carry the numbers into the estimate generator for a branded quote.

How painters price a job

Most painting estimates come down to two numbers: materials and labour. Materials are paint, primer and sundries, usually with a markup to cover buying, collecting and storing them. Labour is prep time plus painting time, and painting time is area divided by how fast your crew works.

This calculator keeps those pieces visible so you can see which one drives the price, then adjust the one you control.

From estimate to website

Customers often look up a painter's website before they accept an estimate. A page listing the work you do, the areas you cover and how you price it makes your estimate easier to trust. The brief at the bottom of the tool starts that page for you.

Tips

Frequently asked questions

How is the wall area worked out?

For each room: 2 x (length + width) x height, minus the doors and windows at the sizes you set, plus length x width if the ceiling is included. Areas are multiplied by the number of coats for paint and counted once for primer.

What coverage should I use?

Use the figure on the paint's data sheet or can. Many interior wall paints state roughly 350 to 400 square feet per gallon (about 8.5 to 10 square metres per litre) on smooth surfaces, and less on rough ones. The default here is only a starting point; replace it with your product's number.

What is the production rate?

How much area one painter covers in an hour for one coat, after prep. It depends on the surface, the tools and the crew. The calculator divides the total painted area (all coats) by it to get painting hours, then adds your prep hours.

Does this include trim, doors and cabinets?

No. It covers walls and optional ceilings. Add trim, doors or cabinets as extra prep or labour hours, or price them as separate lines in the estimate generator.

Can homeowners use it?

Yes, for paint quantity. The labour and markup fields are designed for contractors pricing work, so a homeowner getting quotes should use them only as a rough check.
