Lawn Seeding Cost Calculator
Estimate the total cost to seed a lawn by entering your yard's square footage, grass type, site prep level, labor rate, and whether you want starter fertilizer. Ideal for homeowners budgeting a new lawn or reseeding project.
About this calculator
This calculator breaks your total lawn seeding cost into four components. Seed cost is determined by multiplying the lawn area (sq ft) by a per-sq-ft rate that varies by grass type — e.g. premium turf-type tall fescue costs more per sq ft than basic ryegrass. Site preparation adds a per-sq-ft cost based on the level of work required (light raking vs. full tilling). Labor is calculated as: labor cost = laborRate × ⌈area / 1000⌉ × 2.5 hours, meaning every 1,000 sq ft is assumed to require 2.5 labor-hours. Finally, if starter fertilizer is selected, an additional $0.08 per sq ft is added. The full formula is: Total = (area × grassType) + (area × preparation) + (laborRate × ⌈area/1000⌉ × 2.5) + (includeStarter ? area × 0.08 : 0). This gives a realistic all-in estimate before you call a landscaper or visit the garden center.
How to use
Suppose you have a 3,000 sq ft lawn, choose a mid-range grass seed at $0.05/sq ft, light site prep at $0.02/sq ft, a labor rate of $25/hr, and you want starter fertilizer. 1. Seed cost: 3,000 × $0.05 = $150 2. Prep cost: 3,000 × $0.02 = $60 3. Labor: $25 × ⌈3,000/1,000⌉ × 2.5 = $25 × 3 × 2.5 = $187.50 4. Fertilizer: 3,000 × $0.08 = $240 5. Total: $150 + $60 + $187.50 + $240 = $637.50 Adjust the labor rate or grass type to see how your total changes instantly.
Frequently asked questions
How much does it cost to seed a 5,000 sq ft lawn on average?
For a 5,000 sq ft lawn, total seeding costs typically range from $500 to $1,500 depending on grass type, local labor rates, and how much site preparation is needed. Seed alone might cost $75–$250 for that area, while labor and prep can add several hundred dollars more. Using this calculator with your specific inputs gives a more accurate number than any national average. Including starter fertilizer adds roughly $400 for that size lawn, but it significantly improves germination rates.
What is the difference between seeding and sodding a lawn in terms of cost?
Seeding is almost always cheaper than sodding — typically 50–75% less per square foot — because you're paying for seed rather than pre-grown turf rolls. However, seeding requires more patience, as germination and full establishment can take 2–3 growing seasons. Sodding gives you an instant lawn but involves higher material and labor costs. This calculator focuses on seeding costs, helping you decide whether the savings justify the longer timeline.
Why should I include starter fertilizer when seeding a new lawn?
Starter fertilizer is specially formulated with higher phosphorus levels that promote strong root development in newly germinated grass. At roughly $0.08 per square foot, it's one of the most cost-effective additions to a seeding project. Without it, seedlings may germinate but struggle to establish deep roots, especially in nutrient-poor or compacted soils. Most lawn care professionals recommend it for new seedings because it can cut establishment time by several weeks. The calculator lets you toggle it on or off so you can weigh the cost against the benefit.
