Aeration and Overseeding Pricing Calculator (per 1,000 sq ft)

How much does aeration and overseeding cost, and what should you charge?

Published rates put core aeration with overseeding at roughly $0.13 to $0.18 per square foot — about $1,300 to $1,800 on a 10,000 sq ft lawn — with aeration alone lower and a premium seed-and-starter package higher (CountBricks). Contractors pricing the same lawn work from the other direction: crew hours, machine time and materials, plus the margin they need. The calculator above does both, and shows you where the two answers meet.

Two questions, one lawn

What it costs is the homeowner’s question, and the calculator answers it the way the cost guides do: lawn area times a per-square-foot package rate, with the job broken back down into aeration labor, seed and starter fertilizer so you can see which part of the tier you are paying for. A bags-to-buy line keeps you from over- or under-buying at the supplier.

What to charge is the operator’s question, and it is a different calculation entirely. That mode prices from your side of the invoice: passes over the lawn, how much ground the machine really covers per hour, drive and trim-out time, crew size, your burdened labor cost, the machine’s cost for the day, and your target margin. It reports the job cost, the price, gross profit, cost and price per 1,000 sq ft, and revenue per crew-hour — then holds that price against the published band so you can see at a glance whether your cost base leaves you under the going rate or above it.

Two of those inputs are yours alone. Burdened cost per crew-hour — wage plus payroll taxes, workers’ comp and insurance — comes out of the labor burden rate calculator, and the hourly overhead you need to recover comes out of the overhead recovery rate calculator. No published figure substitutes for either one, so both ship here as placeholders rather than benchmarks. If aeration is one line in a wider seasonal programme, price the programme in the lawn care pricing calculator and use this page for the aeration line inside it.

The pricing method — why the job is built as separate lines rather than one blended rate, and what this season’s input costs are doing to each of them — belongs to the fall aeration and overseeding pricing guide. This page is where you run the numbers.

The unbillable half hour matters more than operators expect. Drive time, unload, trim-out and reload do not shrink when the lawn does, so on a small property they can outweigh the machine time completely. That is the mechanism behind the job minimum: Homewyse frames residential aeration around a two-hour minimum labor charge, and the calculator floors small lawns at your minimum rather than letting area times rate quote a job you would lose money on.

Aerating and dethatching are not the same job

This is the most common confusion in the whole service, and it is worth being precise about, because selling the wrong one wastes a visit.

Thatch is the spongy organic layer between the green growth and the soil surface. A thin layer is useful; the trouble starts when it thickens. University of Wisconsin–Madison Extension puts excessive thatch at over half an inch thick, notes that lawn problems often begin as thatch accumulates past that thickness, and — worth telling customers — states plainly that clippings returned after mowing do not cause thatch, despite the widespread belief that they do.

Core aeration removes plugs. Iowa State Extension describes cores roughly three-quarters of an inch in diameter and three inches long, and says a properly aerated lawn should end up with 20 to 40 holes per square foot — more than most machines produce in one pass, which is why several passes are often necessary. The holes relieve compaction, improve surface drainage and get oxygen into the root zone, and they are also what gives overseeded grass a seed-to-soil contact point instead of a bed of dead material to sit on. Iowa State also warns off spike-type devices that simply punch holes, because they compact the soil rather than removing any.

Dethatching, or power raking, tears the thatch layer out mechanically. It is the harsher of the two. Wisconsin Extension describes mechanical dethatching as very destructive, notes that grasses rooted in thatch tear out easily, and rates core aerification the better recommendation, because aerating both helps degrade thatch and corrects the soil conditions that encourage it in the first place. Penn State Extension reserves dethatching for thatch of an inch or more, and only during cool weather with adequate moisture.

The practical rule for an operator: measure before you quote. Cut a small wedge out of the turf and look at the layer. Under half an inch, aerate. Around an inch or more, dethatching becomes a real conversation — and it is a heavier, slower job that should be priced as its own service, with overseeding assumed rather than optional afterwards.

The window is a cool-weather window

Penn State Extension puts aeration in cool weather — early to mid-spring, or late summer to early fall — and Iowa State names September and April as the best months in Iowa for Kentucky bluegrass and other cool-season lawns. Those are northern-hemisphere months and cool-season turf; read the rule underneath them rather than the calendar. What the timing is really asking for is cool weather, adequate moisture, and enough growing season left for seedlings to establish before the turf shuts down. Apply that to your own hemisphere, climate zone and grass type.

The commercial consequence is that the window is short and everybody’s is open at once. Route density decides whether the season is profitable, which is a scheduling problem more than a pricing one.

What moves the number

Area first: measure the turf you will actually aerate, not the lot, with the lawn area calculator — beds, driveway and house can be a third of a parcel. Then seed: the grass seed calculator converts your seeding rate into pounds and bags, and overseeding runs at roughly half the rate of a new lawn. If the package includes starter fertilizer, the fertilizer rate calculator sizes the bag count. Soil pH is the quiet one — the lime and pH amendment calculator covers the amendment side of a fall renovation, and a pH problem will limit what new seedlings do with any of it. If you sell this as one visit inside a season-long program rather than a one-off, the annual fertilization schedule template prints the fall feed that runs alongside the overseed and every other visit around it.

Machine coverage is the input most worth replacing with a measured number. Manufacturer figures are open-field maximums — Billy Goat rates its PL2500 series at up to 42,550 sq ft per hour — and no real yard with gates, beds and slopes runs at that. Time one job with a stopwatch, divide, and use your own figure forever after. Everything downstream of it in the operator mode is a multiple of that number.

Aeration and overseeding rarely sell alone. When the thatch layer is the reason the seed will not reach soil, what to charge to dethatch a lawn prices the pass that has to happen first, and on a bare or regraded lot pricing a hydroseeded lawn is the faster route to cover than slit-seeding. If the renovation is the anchor visit in a longer agreement, what a season-long treatment program should bill spreads the feeds and weed control either side of it.
