Cost estimating for quotes in landscaping: how to cost quotes that pay off

Cost estimating for quotes in landscaping does not decide your profit at the end of the year. It decides it the moment you write the price into the quote. If your costing in landscaping only multiplies the crew's hourly wage by a markup that feels right, you often work for months on sites that actually make a loss, and you only notice when liquidity gets tight in winter. Full order books are no proof of healthy prices. On the contrary: if you are booked up all the time and still have nothing left over, you are very probably pricing too tightly.

This article covers the numbers side: cost components, the hourly charge-out rate with a traceable worked example, and the typical mistakes. How you then turn a sound cost estimate into a professional quote quickly, in other words the process behind it, is described in the article on preparing quotes in landscaping.

The cost components of your estimate

A quote only pays off if every component is fully included. In landscaping, these are essentially seven items:

Productive labour costs. The basis is not the gross hourly wage, but what a billable hour actually costs you. This includes the non-wage labour costs (employer contributions to social security, employers' liability insurance, statutory levies, holiday and Christmas bonuses), and the unproductive time: holidays, public holidays, sickness, set-up and loading time, non-billable travel time, workshop days. You pay for all these hours, but you cannot sell them. They have to be allocated to the productive hours.

Machinery and equipment costs. Excavator, wheel loader, plate compactor, van: depreciation, financing costs, insurance, maintenance, repairs and fuel and lubricants, divided by the realistic operating hours per year, not by theoretical full utilization. A machine that runs 300 hours a year costs many times more per hour than one that runs 900 hours.

Material and plants. Purchase price plus procurement costs (freight, trips to the wholesaler) plus a surcharge for procurement effort, storage, leftover quantities and breakage. For plants, also: the risk of losses and failure to establish, and any agreed establishment maintenance. Passing material through 1:1 at the purchase price means giving away all the effort around it.

Subcontracted work. Subcontractors (e.g. earthworks, electrical work for garden lighting) need a surcharge for coordination, site management and your warranty risk: you are liable to the client for their work.

Site overheads. Costs that are attributable to the site, but not to any single line item: site set-up, journeys to and from the site, skips and disposal, small equipment, safety measures, on-site management.

Administrative overheads. Office, bookkeeping, software, phone, advertising, insurance, tax advice, and your own owner's salary if you are a sole trader and not on the payroll. This block is underestimated most often, because it is not visible on any site.

Risk and profit. Risk covers the entrepreneurial risk: warranty, weather downtime, establishment problems, bad debts. Profit is not a bonus, but the source of reserves, replacement investments and growth. If you estimate costs without this component, you break even at best, and you are in the red with the first warranty claim.

Hourly charge-out rate in landscaping: step by step

The hourly charge-out rate in landscaping is the minimum price you have to charge per productive working hour so that all cost components are covered. This is how you calculate it. All figures are example values; use your own business figures:

Step 1: Determine the productive hours per employee per year.

Item	Example value
Working days per year (excluding weekends)	250 days
− Holidays	30 days
− Public holidays	11 days
− Sickness (your business's empirical value)	10 days
= Days present	199 days
× 8 hours = hours present	1,592 h
− Unproductive time (set-up, loading, workshop, ~15%)	≈ 240 h
= Productive, billable hours	≈ 1,350 h

Step 2: Determine the annual labour costs.

Item	Example value
Annual gross wage (incl. holiday/Christmas bonus)	€42,000
+ Non-wage labour costs (employer contributions, employers' liability insurance, levies; here 45%)	€18,900
= Annual labour costs	€60,900

Step 3: Put it together.

Calculation step	Example value
€60,900 ÷ 1,350 h = productive labour costs	€45.10/h
+ Overhead surcharge (site + administration, here 25%)	€56.40/h
+ Risk & profit (here 10%)	≈ €62/h net

In this example, a gross wage of around €20/h therefore becomes a charge-out rate of around €62/h: more than three times as much. This very gap is the reason why "hourly wage plus a little" never works in landscaping if you want to estimate a quote that pays its way. You derive your surcharge rates for overheads and for risk & profit from your own bookkeeping (last year's overheads ÷ productive labour costs), not from gut feeling or other people's figures.

The 5 most common costing mistakes in landscaping

1. Forgetting unproductive hours. If you calculate with 1,900 instead of 1,350 billable hours, you set your charge-out rate around a third too low. This is the most expensive single mistake, because it is in every quote.

2. Machinery costs "in there somewhere" as a lump sum. If the excavator is not costed as a separate item with realistic operating hours, your labour share subsidizes the machine. Machinery-intensive sites then look profitable, but they are not.

3. Variations not settled. Rock in the ground, pipes and cables, client requests midway through: if you "go along with" changes without a written variation order, you give away exactly the margin you costed properly beforehand. Managing variations is part of costing.

4. Gut-feeling price under pressure. "The client has two other quotes", and straight away 10% comes off. But a discount does not act on turnover; it acts almost fully on your profit component: with 10% risk & profit in the estimate, a job with a 10% discount works for nothing.

5. Overheads set too low. Office, software, fleet management, owner's salary: if you estimate this block instead of deriving it from your bookkeeping, you are almost always too low. Check the surcharge against the real figures at least once a year.

The underestimated lever: making the value visible

Even the most careful cost estimate is of little use if, in the end, the client only sees a number. A garden project quickly costs several thousand to ten thousand euros, and on paper a €25,000 quote from you and a €21,000 quote from a competitor are the same abstract list of line items. If clients can only compare numbers, they compare numbers. A discussion about price is then inevitable.

The lever: show the client what they get for their money, before anything is built. With GardenPilot Professional, you create photorealistic visualizations of the client's real garden from a smartphone photo in minutes; the house and the viewing angle remain recognizable, only the garden changes. Together with the client folder, as a PDF or protected link, your list of line items gets an image that lets you talk about the garden in the client meeting, and not only about the price. Whether this affects your closing rate is best measured in your own business; how to do that is described in the same article. And the costing side of this tool is simple: around €17–25 net per client project, without a subscription. With job values in the four- to five-figure range, that is a small line item. The details are on the pricing page.

Important for context: GardenPilot is not commercial costing or bill-of-quantities software and does not aim to replace it. It complements your cost estimate in the sales phase, where jobs are won or lost over the price.

Test it on a real project: your first client project is free, via the partner page: project start with three visualizations plus the detailed concept; further variants are not included. Upload a client photo, look at the visualizations, and judge for yourself whether it changes your next sales conversation.

Frequently asked questions

How do I calculate the hourly charge-out rate in landscaping?

In three steps: first, determine the productive, billable hours per employee per year (hours present minus set-up, loading and other unproductive time). Second, divide the full annual labour costs (gross wage plus all non-wage labour costs) by these productive hours. Third, add surcharges for site and administrative overheads as well as for risk & profit. You derive the surcharge rates from your own bookkeeping.

How much profit do you build into a landscaping estimate?

There is no universally valid percentage that can be stated seriously. The right approach is based on principles: risk & profit must cover your warranty and default risk and also finance reserves and investments. If you only estimate to break even, the first warranty claim or machine breakdown is paid out of your assets. Set the rate individually for your business and check every year in the post-project costing whether it was actually left over.

What belongs in the cost estimate for a quote in landscaping?

Seven components: productive labour costs including non-wage labour costs and allocated unproductive time, machinery and equipment costs, material and plants with a surcharge, subcontracted work with a surcharge, site overheads, administrative overheads (including owner's salary) and risk & profit. If one of them is missing, the price is too low, even if the quote looks adequate at first glance.

Why is my hourly charge-out rate so much higher than the hourly wage?

Because the gross wage is only a fraction of your costs: non-wage labour costs, hours that are paid but not billable (holidays, sickness, set-up time), the business's overheads, and risk & profit come on top. In the worked example above, a gross wage of around €20/h becomes a charge-out rate of around €62/h. A charge-out rate close to the gross wage is not a competitive advantage, but a warning sign.

Does GardenPilot help with costing my quotes?

No, and we deliberately say this clearly: GardenPilot is not costing or quoting software and replaces neither bill-of-quantities costing nor site measurement. GardenPilot comes in before that: it makes the value of your carefully costed quote visible by letting the client see their real garden as a photorealistic visualization before anything is built. Whether this reduces price discussions in your business is best measured yourself. You continue to cost your commercial quote in your usual system.
