Lawn Aeration Cost Calculator
Estimate the total cost of lawn aeration based on your lawn size, aeration method, grass type, and service options.
Lawn Size (square feet)
Aeration Method
Core / Plug Aeration (recommended) Spike Aeration Liquid Aeration
Service Type
Professional Service DIY – Equipment Rental
Grass Type
Standard (Fescue, Bluegrass, Ryegrass) Thick / Dense (Bermuda, Zoysia, St. Augustine)
Add Overseeding?
No Yes
Add Fertilizing?
No Yes
Region / Climate Zone
National Average Northeast (higher labor costs) West Coast (highest labor costs) Midwest (below average) Southeast (lowest labor costs) Southwest

#### Formula
Aeration Cost = max( (Lawn Size ÷ 1,000) × Base Rate × Grass Multiplier × Region Multiplier, Minimum Fee )
Overseeding Cost = Lawn Size × $0.12 × Region Multiplier (if selected)
Fertilizing Cost = Lawn Size × $0.06 × Region Multiplier (if selected)
Total Cost = Aeration Cost + Overseeding Cost + Fertilizing Cost
Typical Range = Total Cost ± 20%
- Base Rate (Professional, per 1,000 sq ft): Core $15 | Spike $10 | Liquid $12
- Base Rate (DIY Rental, per 1,000 sq ft): Core $5 | Spike $2 | Liquid $3
- Grass Multiplier: Standard = 1.0 | Thick/Dense = 1.20
- Minimum Fee: Professional = $75 | DIY = $30
