/ Your job

Walls only. Quick estimate: perimeter × 2.4m wall height.

Ceilings only — roughly the floor area of the rooms being painted. Quoted at the cheaper ceiling rate.

Tick for a big colour swing to/from dark. Adds an extra coat — bumps the wall, ceiling and exterior rates by your colour-change uplift.

Light prep (sugar-soap, spot fill) is in the rate. Tick when the surface needs full sanding, render repair, wallpaper strip, or multiple primer coats.

Estimate only. Real prices depend on your site, materials and access. Built on the Karven calc engine at typical 2026 AU rates.

What the estimate covers

  • Two coats of paint over prepared surfaces at typical AU rates
  • Cutting in, rolling and basic masking labour
  • Interior walls and ceilings, or exterior, depending on what you toggle
  • An extra coat allowance when you are making a major colour change

What pushes the price up

  • Total area is the biggest lever - more square metres, more cost
  • Heavy prep (filling, sanding, undercoat) on tired surfaces
  • Two-storey exterior work that needs scaffolding or access gear
  • Trim, doors, windows and ceilings on top of plain walls

FAQ

Repaint cost questions

  • How much does it cost to repaint a house in Australia?

    An interior repaint of a typical 3-bedroom home runs about $5,500 to $16,500 depending on area, prep and whether ceilings and trim are included. Exterior repaints vary widely with access and condition.

  • What is the cost per square metre to paint?

    Interior walls usually run $10 to $20 per square metre for two coats with light prep. Heavy prep, ceilings, dark-to-light colour changes and exterior access all push the rate up.

  • Does this include prep and undercoat?

    The base estimate assumes two coats over reasonable surfaces. Toggle the prep option on if walls need filling, sanding or undercoat, and the band lifts to reflect the extra labour.

  • How do I get an exact painting quote?

    This is a ballpark. For a fixed, itemised quote a local painter running Karven can measure up and send a branded quote fast. Tap Get an exact quote to begin.
