About Figure My Build

Figure My Build exists because of a familiar moment: standing in a store aisle, phone in hand, staring at a calculator result that says "1.23 cubic yards", with no idea how many bags that actually means.

Our calculators finish the job other calculators start. Every tool answers the buying question: how many bags, boxes, sheets or gallons to put on the cart, using yield and coverage figures published by the manufacturers themselves (Quikrete, Sakrete, Sherwin-Williams, Belden Brick and others), with a sensible waste allowance and an estimated cost.

Each formula is verified against its source and tested against hand-worked examples before a calculator goes live, and every result page shows the maths in plain words so you can check it yourself. No accounts, no paywalls. Just the list.

Results are planning estimates. Site conditions vary, products vary, and structural work belongs under your local building code. Our disclaimer on every page says exactly that, because a tool you can trust is a tool that's honest about its limits.
