The majority of people would assume that I am a business coach. So you would expect me to tell you that coaching is always worth it. I am not going to do that.

I have turned away agency owners who were not ready for coaching. I have had honest conversations with people where the answer was “not yet” or “this is not what you need right now.” Because coaching is an investment, and like any investment, it either delivers a return or it does not.

The question is not “is business coaching worth it?” in the abstract. The question is: given where your agency is right now, what is the expected return on spending £12,000 to £20,000 on coaching over 12 months? And can you calculate that before you sign up?

You can. Here is how.

The Wrong Way to Evaluate Coaching

Before we get into the numbers, let me tell you what does not work.

Evaluating coaching based on how it makes you feel. Feeling supported, feeling motivated, feeling less alone. Those things matter. But they are not a return on investment. If you spend £15,000 and the main outcome is that you feel better about running your business, that is therapy, not coaching. Nothing wrong with therapy. But call it what it is.

The other mistake is evaluating coaching based on what the coach promises. “I will help you double your revenue.” “I will get you to seven figures.” These are marketing claims, not business cases. Any coach worth working with will tell you that results depend on what you do with the advice, not on the advice itself.

The right way to evaluate coaching is simple: identify the specific financial outcomes you expect, estimate their value, subtract the cost, and see if the number is positive.

Right?

How to Calculate the ROI

Here is a straightforward framework. No complicated maths. Just honest numbers.

Step 1: Identify Your Revenue Levers

Every agency has a small number of changes that would produce a meaningful revenue increase. Common ones I see:

Pick the one or two levers most relevant to your agency. Be conservative with your estimates. Use the lower end of what you think is achievable.

Step 2: Estimate the Financial Impact

Let me use a real example. An agency owner I worked with was running at about £35,000 a month in revenue. Good creative work, decent team, but stuck. He had been at that number for 18 months.

We identified three specific changes:

  1. Restructure pricing from hourly to project-based (estimated impact: +£3,000/month)
  2. Introduce a retainer offer for existing clients (estimated impact: +£5,000/month in retained revenue within 6 months)
  3. Improve the sales process to increase close rate from 22% to 30% (estimated impact: +£4,000/month based on existing pipeline volume)

Combined estimated impact: £12,000 per month, or £144,000 per year.

That is not a promise. That is a calculation based on his specific numbers, his specific pipeline, and conservative assumptions about what would change.

Step 3: Subtract the Cost

His coaching investment was £20,000 for 12 months. The estimated return was £144,000 in additional annual revenue. Even if we cut that estimate in half to be cautious, that is £72,000 against a £20,000 investment.

The ROI calculation: (£72,000 - £20,000) / £20,000 = 260%.

What actually happened? Within 9 months, his monthly revenue went from £35,000 to £55,000. That is £240,000 in additional annual revenue against a £20,000 investment.

Step 4: Factor in the Compounding Effect

Revenue increases from coaching are not one-off. A retainer client paying £1,500/month does not stop paying after the coaching ends. A better close rate does not revert to the old number. The structural changes compound.

That £55,000/month did not drop back to £35,000 when the coaching programme finished. It kept growing because the systems, pricing, and processes we built were embedded in the business.

This is the bit that makes coaching genuinely worth it when it works. You are not paying for 12 months of advice. You are paying for permanent structural improvements to how your business operates.

When Coaching Is NOT Worth It

I would be doing you a disservice if I did not cover this. Coaching is not the answer for every agency at every stage. Here are the situations where I would tell you to wait.

You are under £200K in revenue. At this stage, what you need is clients, not coaching. Your problem is not strategy or systems. It is sales volume. Spend the £15,000 on marketing, lead generation, or hiring a part-time salesperson. Come back to coaching when you have the revenue to invest from a position of stability rather than desperation.

You are not willing to change. Coaching only works if you implement what you learn. I have worked with agency owners who nodded along in every session, agreed with every recommendation, and then changed nothing. After three months I had an honest conversation: “This is not working because you are not doing the work. We should stop.” That is an uncomfortable thing to say, but it is the truth. If you want validation, not change, coaching is not the right investment.

Your problem is personal, not business. If you are burned out, in a difficult personal situation, or struggling with your mental health, a business coach is not the right support. You need a therapist, a counsellor, or time away from the business. I have referred people to other professionals when it became clear that the business problem was actually a personal one. There is no shame in that. It is the responsible thing to do.

You cannot afford it without putting the business at risk. Coaching should come from profit, not from your last reserves. If spending £15,000 means you cannot make payroll next month, that is not an investment. That is gambling. Fix your cash flow first, build a buffer, then invest in coaching.

What Good Coaching Actually Delivers

Beyond the revenue numbers, here is what shifts when coaching works properly.

Clarity on pricing. I cannot tell you how many agency owners I have worked with who were undercharging by 30% to 50% and did not realise it. When I lost £30,000 on a single project because I quoted £5,000 on a project with a £35,000 budget, that was the moment I understood that pricing is not about cost. It is about value. Good coaching gives you the frameworks and the confidence to charge properly.

A sales process that does not depend on you. If every new client comes through you personally, your agency has a ceiling. Good coaching helps you build a repeatable sales system that your team can run. Pipeline tracking, proposal templates, follow-up sequences, close rate monitoring. The boring stuff that makes revenue predictable.

Operational systems that scale. When I was running my agency, I spent the first five years being the quality control department. Every piece of work went through me before it went to the client. That does not scale. Coaching helped me build systems, checklists, and approval processes that maintained quality without my involvement.

Accountability. This is the one people underestimate. Having someone who knows your numbers, knows your goals, and asks you every fortnight “did you do what you said you would do?” is worth more than any framework or tool. Most agency owners have no one who holds them accountable. Their team will not do it. Their partner does not understand the business well enough. Their friends are in the same boat. A good coach fills that gap.

How to Choose the Right Coach

If you have done the ROI calculation and it makes sense, here is what to look for.

Have they done it? Not theorised about it. Not read about it. Actually built and run the type of business they are coaching. I built an agency from nothing to £2.2M over 11 years and sold it. That experience is the foundation of everything I teach. If your coach has not operated at your level or above, they are guessing.

Do they have a system? Good coaching is not just conversation. It is structured. There should be a programme, a framework, regular accountability checkpoints, and measurable targets. If the coach’s approach is “we’ll see what comes up each session,” that is not coaching. That is a chat.

Will they tell you the truth? The most valuable thing a coach can do is tell you what you do not want to hear. Your pricing is too low. Your biggest client is a liability. You need to let go of that team member who is not performing. If the coach only tells you what you want to hear, you are paying for a cheerleader.

Can they show results? Not testimonials about how someone “felt supported.” Specific financial outcomes. Revenue increases. Margin improvements. Successful exits. If the coach cannot point to specific, measurable results from their clients, be cautious.

The Bottom Line

Business coaching is worth it when:

  1. Your agency is generating enough revenue that you can invest from profit (typically £300K+ annual revenue)
  2. You can identify specific financial levers that coaching would help you pull
  3. The estimated ROI exceeds 200% even on conservative assumptions
  4. You are genuinely prepared to implement changes
  5. The coach has relevant operational experience and a structured programme

If those five conditions are met, coaching is one of the highest-return investments an agency owner can make. If they are not, spend the money elsewhere and revisit when you are ready.
