About pourplot

pourplot is an independent site of free calculators for concrete, fence posts and yard materials. It is built for homeowners, DIYers and small contractors who want the right amount the first time: not short halfway through a pour, and not paying for a pallet of extra bags.

Why it works the way it does

• Quick answer, full plan when you need it. Most people just need the number. Anyone planning a bigger job can switch to the drawing and the printable ticket.
• Sourced numbers. Bag yields come from the manufacturer's data sheets, material weights and cost ranges from published guides. Each page names its sources, and the methodology page shows every formula.
• Your data stays yours. We don't have accounts or a database of calculations. Everything you enter lives in the page link on your own device.

Independence

pourplot is not affiliated with any concrete, lumber or materials brand. Where we name a product (for example QUIKRETE bag yields or Sonotube forms), it is because their published data is the clearest public source.
