How to Calculate Paint Price for Any Project
Calculating the price of paint for a project is straightforward: multiply the litres you need by the price per litre, then add consumables like primer, brushes, and rollers. Our paint price calculator does the litre calculation for you — just enter your dimensions and price per litre.
The key to an accurate price estimate is getting the quantity right first. Over-estimating by even 10–15 litres on a large project can add $150–$300 in unnecessary costs. Use our calculator to nail the quantity before spending a dollar.

Buy Larger Tins to Save Money
Price Per Litre vs Tin Size
The larger the tin, the lower the price per litre. A paint brand might sell a 1L tin at $18/L, a 2.5L at $14/L, and a 10L at $11/L. For any project requiring more than 3 litres, buying the larger tin will almost always save money.
Example Saving on a Bedroom
For a bedroom needing 7 litres: buying 7 × 1L tins at $18/L = $126. Buying 1 × 5L + 1 × 2.5L at $13/L average = $91. Saving: $35 on the same paint.
Ways to Save on Your Paint Budget
Always buy the largest tin size you need — it's cheaper per litre
Compare prices online before buying from a single supplier
Trade paint stores (not just hardware chains) often have better prices and quality
Ask about end-of-run colours — discontinued shades are often discounted 30–50%
Calculate before you buy — over-purchasing is the most common cause of excess paint spend
