What is HomeCalc?
HomeCalc is a free planning tool for homeowners who want a quick way to estimate common home and yard project materials before they buy.
The site includes a map-based lawn measuring tool and calculators for mulch, grass seed, fertilizer, gravel or rock, room paint, and deck stain.
Why HomeCalc exists
Many home projects start with the same basic question: how much material do I need? HomeCalc helps answer that question by combining your measurements with common coverage, depth, coat, and buffer calculations.
The goal is to give you a useful starting point before visiting a store, comparing products, ordering delivery, or calling a contractor.
How to use HomeCalc
- Use the map tool to trace a lawn, mulch bed, gravel area, or other outdoor project area.
- Send the measured square footage to the calculator.
- Choose a project type and adjust coverage, depth, coats, or buffer as needed.
- Review the shopping list and calculation breakdown.
- Verify final product coverage and pricing before buying.
Important note
HomeCalc provides planning estimates only. Actual material needs can vary based on product label instructions, surface condition, slope, waste, weather, application method, local rules, and installation conditions.
