Five focused planners
From first measurement
to the checkout list.
Each calculator handles multiple areas, transparent formulas, product package sizes, waste, and optional local prices.
Independent by design
A planner—not a product funnel.
Use the package coverage and prices available where you live. The result explains its assumptions, so you can check every number.
Plan the whole project
Add rooms, beds, pours, or fence runs instead of repeating a one-field calculator.
Price real packages
Compare bag or box counts and keep the exact quantity visible beside the rounded purchase.
See the formula
Every result includes assumptions, conservative allowances, and a worked example.
Save without signing up
Your project can stay in localStorage, travel in a share link, or print to a PDF on your device.
Measure with context
Guides that make the
numbers more useful.
