- 3
Plan your materials and costs
Use the results to help prepare your material requirements and budget, then add supplier prices in the cost estimator.
A proper estimating tool, not a blank spreadsheet.
Every calculator follows the same clear layout, so once you have used one you can use them all. Open the Start Here sheet, pick a tab and begin measuring.
Clear inputs and results
Every sheet separates the cells you fill in from the calculated results, with units beside each figure.
Adjustable assumptions
Product sizes, coverage rates, densities and waste percentages are inputs, so the numbers follow your specification.
From quantities to budget
Take quantities into the Material Cost Estimator, add unit costs and suppliers, and see a running material total.
Print-ready sheets
Each calculator is set to fit one printed page, with BuildPlan branding and a page footer.
