Landscaping & yard calculators
Free, no-signup landscaping calculators for homeowners, DIYers and buyers — lawn & seed, landscape materials (mulch, soil, gravel), hardscaping, fencing & decking, irrigation & watering, and tree & plant care. Every tool works on the quantities you measure and the prices you enter, and shows its formula, a worked example and a reference table.
Lawn & Seed
The traffic anchor: grass seed and lime by area, sod rolls and pallets, fertilizer pounds from the N rate and %N, a lawn-area estimator, and artificial-turf and lawn-care cost from the prices you enter.
All Lawn & Seed tools →Landscape Materials
The biggest volume magnets: mulch, topsoil, gravel, sand, compost and decorative stone by area and depth (cubic yards, bags and tons), plus a bulk-material delivered cost from your own supplier quote.
All Landscape Materials tools →Hardscaping
Patios and walls: paver count from the paver size, paver-patio cost, retaining-wall block count and cost, polymeric-sand bags for the joints, and the gravel and sand for a paver base.
All Hardscaping tools →Fencing & Decking
Fence and deck take-offs: posts, rails, pickets and panels from length and spacing, fence cost per foot, deck boards and fasteners from board size, deck cost, and post-hole concrete bags.
All Fencing & Decking tools →Irrigation & Watering
Water it right: sprinkler-system cost, irrigation zones from available GPM, the weekly watering requirement and run time (0.623 gal per sq ft per inch), drip-line flow, and rain-barrel harvest.
All Irrigation & Watering tools →Tree & Plant Care
Trees and beds: tree-removal, stump-grinding, trimming and land-clearing cost from your quotes, the mulch-ring volume around a tree, and how many plants a bed needs from the spacing. Tree work is licensed-arborist only.

Tree & Plant Care
Built for the whole yard project — and to stay correct forever
LandscapingCalcs gathers the calculations homeowners, DIYers and buyers reach for across a yard project — lawn & seed → bulk landscape materials → hardscaping → fencing & decking → irrigation & watering → tree & plant care — in one focused hub, in US units, without signup, with transparent formulas. Every tool shows not just the answer but the underlying formula, a worked example and a reference table.
Because the tools rest on timeless landscaping math (bulk material cu yd = area × depth ÷ 324; tons = cu yd × density; grass seed lb = area × rate ÷ 1,000; sod pallets = area ÷ 450; pavers = area ×(1+waste) ÷ paver size; retaining-wall blocks = wall face ÷ block face; fence posts = length ÷ spacing + 1; deck boards = area ÷ board coverage ×(1+waste); watering gal = area × inches × 0.623; plant count = area ÷ spacing²; cost = quantity × your unit price) and stable conventions (324 area-depth-to-cubic-yard factor; 27 cu ft per cu yd; 0.623 gal per sq ft per inch; ~13.5 bags of 2 cu ft per cu yd; ~450 sq ft per sod pallet; labeled seeding, density, paver and spacing typicals), they stay correct with no maintenance — no material or service price list, no labor-rate database, no regional cost index. Cost tools use the prices you enter from your own quotes and bills. More at Sources & formulas, Methodology and About. Planning a whole-room interior remodel budget instead? That is a different job — see the sibling site RenovationCalcs.
Estimates, not bids. Every material result is a planning estimate — coverage varies by product, so buy about 5–10% extra and confirm it on the bag. Every cost result is a planning estimate from your own prices, not a bid — get itemized written quotes from licensed, insured landscapers and contractors. Tree removal and land clearing are dangerous — hire a licensed, insured arborist. Retaining walls over about 3–4 ft usually need an engineer and a permit.
