How much does a business consultant cost? An honest look

The price depends less on the consultant than on how they charge. Most business consultants bill in one of four ways: by the hour, by the project, on a monthly retainer, or at a fixed price for a clearly scoped piece of work. Each model puts the risk somewhere else. Once you see where, the price question gets a lot easier.

I'll show you how each model works, what to watch for and how I price my own work, so you have something concrete to compare with.

The four ways consultants charge

• Hourly. You pay for time. Simple and flexible, and the risk sits with you: if it takes longer, you pay more.
• Per project. One price for an agreed result, like a new pricing model or a sales process. The risk moves to the consultant, which is why project prices always include a buffer.
• Monthly retainer. A fixed amount for ongoing access. Great for a steady advisor, expensive if you barely use it.
• Fixed-price session. One problem, one session, one price. The smallest step you can take, and the easiest to judge afterward.

What actually drives the price

Not the hours on the invoice. The price goes up with experience in your exact problem, with how much hands-on work is included and with how vague the scope is. That last one is the expensive one. If nobody can say what done looks like, the meter keeps running.

Someone who has built companies usually costs more per hour than a junior analyst. They also need fewer hours, because they've seen your problem before.

A quick way to check if it's worth it

Put the price next to what the problem costs you. An example: a consultant charges $200 an hour and a project takes 30 hours. That's $6,000. If the problem is your pricing and you're 10 percent too low on $500,000 in revenue, you're leaving $50,000 a year on the table. Then $6,000 is cheap.

If the problem is worth less than the fee, don't hire anyone. Fix it yourself, or leave it.

Hourly or fixed price: which fits you?

Hourly works when the work is open-ended: you want someone in your corner for months and the questions change along the way. Ask for a monthly estimate anyway, so you can budget.

Fixed price works when the question is clear. You know what you want answered, the consultant knows what to deliver and you both know when it's done. For most small business owners, the first piece of work should be fixed price. It keeps both sides honest.

Red flags in a proposal

• No clear scope: "we'll see how it goes", with an hourly rate and no estimate.
• A thick report as the main deliverable. You're paying for decisions, not pages.
• A retainer before anyone has solved a single problem for you.
• They can't tell you in one sentence what you'll have at the end.

Start small

The cheapest way to find out whether a consultant is any good: give them one real problem and see what comes back. If that first piece of work is useful, the rest of the conversation gets easy. If it isn't, you haven't lost much.

How I price my own work

So you can compare, here's how I do it. A free 20-minute intro call to see whether there's a fit. A Business Strategy Session for one clearly scoped problem: a written intake, a 60-minute working session on US Eastern Time and a written action plan, for $595 flat. For ongoing work, hands-on or as your ongoing advisor, an hourly rate with a clear estimate upfront. No surprises afterward.

Not sure which one you need? Start with the session. It's the smallest step that gets you a real answer.
