A potential client contacted me last month asking about a limestone garden sculpture. They had a clear vision, a specific size in mind, and a budget that was roughly one-third of what the project would actually cost.

This happens regularly. Most people have no frame of reference for what stone sculpture costs, and their estimates are based on mass-produced cast concrete pieces they’ve seen at garden centers.

Here’s how I think about pricing commission work, and why the numbers work out the way they do.

The Basic Formula Doesn’t Work

The naive approach to pricing is: estimate hours, multiply by hourly rate, add material cost, add some margin. Simple.

Except stone carving doesn’t work on predictable hourly timelines. That detail that looked straightforward in the sketch might take two hours or eight hours depending on what the stone does. The finish you promised might require three extra days when you discover the particular grain pattern in this block.

If you price strictly on estimated hours, you’re either losing money on difficult projects or overcharging for straightforward ones.

Material Costs Are Variable

Stone prices fluctuate significantly. The limestone I can get this month might be different quality or price than what’s available when you actually want to start the project.

Shipping costs for heavy stone are substantial and vary by distance. A 200kg block costs $50 to ship within the city, $200 to ship interstate.

You also need to factor wastage. That 200kg block might only yield 120kg of finished sculpture after removing unusable sections, cutting the base, and general material loss during carving.

I now price material at actual cost plus 30% to cover variability, shipping, and wastage. This feels high to clients until you explain what it actually covers.

Design Work Is Work

Clients often don’t realise that the design phase is substantial work. They expect to have a conversation, you sketch something, and then carving begins.

In reality, commissioned work often involves multiple sketch iterations, scale models, material samples, and ongoing communication about design decisions. This can easily represent 15-20 hours before any actual carving begins.

I now separate design phase and execution phase in quotes. Design phase is billed at hourly rate, execution phase is fixed price. This makes it clear what clients are paying for and ensures I’m compensated for design time even if the project doesn’t proceed to execution.

Experience Changes Everything

A sculpture that would take me 60 hours now would have taken me 100+ hours three years ago. As my technique improves, the time required for projects decreases.

But that efficiency comes from thousands of hours of practice and many expensive mistakes. Pricing based purely on current execution time doesn’t capture the value of that accumulated experience.

More experienced stone carvers charge higher rates not just because they’re better—though they are—but because they can complete work in less time with better results. You’re paying for efficiency and expertise, not just labour hours.

The Client Relationship Factor

Some clients are easy to work with. They trust your expertise, make decisions promptly, and are flexible about minor design adjustments when the stone suggests changes.

Other clients require extensive communication, request multiple changes mid-project, and want approval on every decision. This communication overhead can double the actual time investment.

I don’t explicitly charge more for difficult clients, but I do factor relationship complexity into whether I accept projects at all. A challenging project with a great client is more appealing than a straightforward project with someone who will make the process painful.

Insurance and Overhead

Running a stone sculpture practice involves costs beyond materials and labour. Public liability insurance for when you’re working on-site. Storage space for tools and materials. Equipment maintenance and replacement. Dust extraction systems. Professional development and skill building.

These overhead costs need to be factored into pricing even though they’re invisible to clients. I estimate roughly 25% of my gross revenue goes to overhead before I see any actual income.

The Difficulty Premium

Not all stone carving is equally difficult. Creating a simple geometric form in limestone is dramatically easier than carving detailed figurative work in marble.

I now apply difficulty multipliers to base rates:

• Simple geometric forms: 1x base rate
• Decorative elements and stylised work: 1.3x base rate
• Realistic figurative work: 1.6x base rate
• Portraiture and highly detailed work: 2x base rate

This captures the reality that challenging work requires more concentration, more precise technique, and carries higher risk of expensive mistakes.

Weather and Timing

Working stone outdoors in Australian weather adds complexity. Summer heat makes long carving sessions exhausting and potentially dangerous. Winter rain delays outdoor work unpredictably.

For outdoor installation projects or work that must occur on-site, I build weather contingency into timelines and pricing. A project that should take two weeks might take four if weather doesn’t cooperate.

Indoor studio work doesn’t have this problem, which makes it easier to price predictably.

The Installation Question

Getting finished sculpture from studio to final location involves logistics that clients often don’t anticipate. A large stone piece might require special equipment to move, structural assessment of the installation site, and professional riggers for safe positioning.

I learned to make installation costs explicit and separate from the sculpture itself. Otherwise clients are surprised when they realise their beautiful finished piece is sitting in my studio and they need to arrange transport and installation.

For smaller works (under 50kg), I can usually deliver and install personally. For larger pieces, I coordinate with professional art handlers but make clear that these costs are additional to the sculpture itself.

Deposits and Payment Structure

I now require 40% deposit before starting design work, another 30% before beginning carving, and final 30% upon completion before delivery.

This protects me from clients who change their minds partway through—I’ve been paid for the work completed. It also protects clients because they’re not paying the full amount until they see the finished work.

Early in my commission work, I tried doing full payment on completion. This created cash flow problems and left me vulnerable to client payment delays.

When to Say No

Not every potential commission is worth taking. Red flags that suggest declining a project:

Clients who want multiple free design iterations before committing. This indicates they see design work as having no value.

Unrealistic budget expectations after you’ve explained actual costs. They’re hoping you’ll somehow deliver for less. You won’t, and everyone will be disappointed.

Unclear decision-making authority. They need to check with partners/committees/etc. on every decision. This drags projects out indefinitely.

Requests for replication of existing well-known works. This is boring work with no creative satisfaction and often copyright complications.

What I Charge Now

My current baseline for commissioned stone work: $85/hour for labour, actual material costs plus 30%, design phase billed separately, difficulty multipliers applied based on project complexity.

A typical small limestone garden sculpture (40cm height, moderate detail) runs $2,800-3,500 including design, materials, and execution. Larger pieces or marble work scale accordingly.

Three years ago I was charging roughly 60% of these rates and losing money on difficult projects. Current pricing is sustainable and fairly compensates for the skill, experience, and risk involved.

The Difficult Conversation

The hardest part of commission work is telling enthusiastic potential clients that their project costs three times their budget. Some people respond well when you explain why. Others think you’re gouging them.

I’ve learned to have this conversation early before investing time in design work. Show examples of previous projects with their costs. Explain material costs, time requirements, and complexity factors. Give them realistic numbers based on what they’re describing.

Sometimes this leads to scaled-down projects that fit their budget. Sometimes they decide to save up and come back later. Sometimes they decide stone sculpture isn’t in their budget and that’s fine too.

The alternative—undercharging and resenting the work or losing money—benefits nobody. Better to be honest about costs and let clients make informed decisions.

What Makes It Worth It

Despite pricing complications, commission work is satisfying when it goes well. You’re creating something specific for someone’s vision. It will exist in a particular place for decades, probably longer than you will.

The pricing challenges are just logistics. Get them right, and you can focus on the actual work of creating meaningful sculpture.

Get them wrong, and you’re stressed about money while trying to do creative work that requires patience and concentration. That’s a recipe for poor results and miserable experience.

Price realistically, communicate clearly, and only take projects that work financially. The sculpture itself is hard enough without adding business problems to the mix.
