How our estimates work
The calculators are designed for project planning. They do not replace an onsite measurement, supplier quote, or contractor proposal.
Quantity & purchasing
Sod starts with measured lawn area, adds the selected waste allowance, and rounds purchasing up to whole pallets using a 450 sq-ft planning pallet.
Cost ranges
Material pricing varies by grass type. Professional ranges respond to site preparation, grading, access, project size and grass choice.
Quantity & purchasing
Mulch volume uses area × depth ÷ 324. Bulk ordering rounds up to the next 0.5 cubic yard, while 2-cu-ft bags round up to whole bags.
Cost ranges
DIY includes material, selected delivery, cleanup allowance and basic tools. Professional estimates add spreading labor and access adjustments.
How map measurement works
Satellite measurement lets the homeowner outline one or more project areas on an aerial map. The site calculates the polygon area using geographic coordinates, converts square meters to square feet, and totals completed sections.
Satellite imagery can be dated or obscured by trees and shadows. Treat the result as a planning measurement and verify critical quantities before ordering materials.
DIY retail benchmark model
The DIY estimate uses a representative retail basket checked August 20, 2026. The current benchmark blends nationally available homeowner products from brands such as Scotts, Vigoro, Sta-Green, Sunday, BioAdvanced, Spectracide, IMAGE and The Andersons.
The model scales a 5,000-sq-ft benchmark to the entered lawn size. The baseline annual program includes three fertilizer allowances, two pre-emergent allowances and one post-emergent allowance. Weed pressure and lawn condition add treatment allowances; a first-year spreader allowance is added when the homeowner does not already own one. This is a cost-comparison model, not a treatment prescription.
