Hold the job steady.
Use one net painted area and one coat count. Products needing different coat counts should be checked in separate plans.
ONE PAINTED AREA · UP TO FOUR OFFERS

A price comparison is not a product recommendation. Different paints may suit different surfaces, finishes and preparation requirements. Use your supplier’s coverage and confirm that the offers are appropriate for your project.
YOUR SIDE-BY-SIDE COMPARISON
Same job.
Different tin totals.
Enter an area, a coat count and at least one offer with coverage and tin volume. Add up to four offers to compare whole-tin quantities and any quoted paint totals.
Or load the clearly labelled hypothetical example to see how the comparison works.
YOUR SHARED PAINTING JOB
Lowest quoted total means the arithmetic total among priced offers. It does not establish equal materials, finishes, performance or suitability.
Whole tins, litres and cost
All offers use the same painted area and coats. Scroll the table sideways on a small screen.
| Offer | Coverage m²/L/coat | Tin L | Needed L | Whole tins | Purchased L | Surplus L | Quoted paint total |
|---|
Litres marked ≈ are shown approximately to three decimal places. Tin quantities use the exact entered decimals before display rounding. Surplus is the model’s purchased litres minus required litres; it is not a promise of paint remaining after use.
Needed vs purchased
All bars use one common scale, set by the largest purchased volume. The peach part shows the estimated surplus created by whole-tin rounding.

No extra allowance, primer, delivery, tools or labour is added. This tool compares one pack size per offer; it does not find an optimal mix of tin sizes.
Read each coverage figure.
The coverage belongs to that offer. This comparison applies your entered number; it does not supply or guarantee real coverage.
Compare complete tins.
A lower tin price can still produce a higher whole-order paint total. Follow the worked example →
