Paint Cost Estimator
Enter price per gallon from your local paint store (CAD) — we multiply gallons needed for an estimated materials total. Tape, rollers, and primer are extra line items so you can budget the full DIY cart, not just the colour can.

Budgeting a DIY room
Materials often run $80–$200 CAD for a typical bedroom including basic supplies. This page estimates paint gallons × your entered price — add 15–20% for brushes, tape, trays, and drop cloths.
Example: 2.5 gallons at $65/gallon ≈ $163 in paint alone. Mid-grade brushes and a roller kit can add $40–$70. Keep a labelled touch-up jar so you are not buying another gallon for one scuff.
Primer and topcoat as two line items
New drywall and bold colour changes need primer — run the gallon math with paint type set to primer, then again for topcoat, or add primer gallons manually to the cost field.
Premium paint costs more per gallon but may cover in fewer coats. Compare cost per finished square foot: (price ÷ coverage) × coats, not sticker price alone.
Where this estimator stops
Labour, ladder rental, and furniture moving are not included. For gallon counts without price, use how much paint do I need. For coverage-only brand math, use the paint coverage calculator.

Frequently asked questions
Should I include primer in the cost estimate?
Run the calculator twice — once with primer paint type and once with topcoat — or add primer gallons manually. New drywall and bold color changes need primer.
Why is my estimate higher than one gallon?
Two coats on walls plus ceiling, waste allowance, and door/window deductions all affect gallons. We round up to whole gallons like the store sells them.
