The Subtraction Audit: Complete Step-by-Step Guide

In 2022, I sat down with a founder who was running a consulting practice, selling two digital products, managing a small course, maintaining a blog, posting on four social media platforms, and exploring a potential SaaS product. She was exhausted, her revenue had plateaued, and she couldn’t figure out why nothing was growing.

The answer was obvious from the outside: everything was growing slowly because nothing was growing fast. Her attention was split across so many initiatives that each one got roughly 15% of her capacity. At 15% capacity, nothing reaches escape velocity.

She didn’t need to add anything. She needed to subtract. Within three weeks of running the Subtraction Audit, she cut her activities to two core focuses: consulting and one digital product. Revenue increased 60% in the following quarter. Not because she worked harder. Because she worked on fewer things.

The Subtraction Audit is the framework I’ve used with my own businesses and with dozens of founders to answer one of the hardest questions in business: what should you stop doing? This guide walks you through the complete process, step by step.

Why Subtraction Works Better Than Addition

The default business response to any problem is addition. Revenue slow? Add a marketing channel. Customers unhappy? Add a feature. Pipeline thin? Add a product line. We’re wired to think that more activity produces more results.

Sometimes it does. More often, it produces more complexity, more overhead, and more fragmentation — all of which slow you down. The best businesses I’ve studied are defined not by what they do, but by what they refuse to do. Their focus is a product of systematic subtraction.

The Subtraction Audit reverses the default. Instead of asking “what should we add?”, it asks “what should we remove?” The answers are usually obvious once you look at the data, but founders rarely look because the addition bias is so strong.

This connects to the core principle behind the Revenue Engine: a simple, clear system where every component matters beats a complex system where most components are mediocre. Subtraction creates simplicity. Simplicity creates speed. Speed creates results.

Step 1: The Complete Activity Inventory (Day 1)

Before you can subtract, you need to see everything. Most founders are shocked by how many activities, commitments, and initiatives they’re running simultaneously. The first step makes the full picture visible.

What to do: List every activity, product, service, channel, and commitment that consumes your time or resources. Be comprehensive. Include:

• Every service you offer
• Every product you sell
• Every marketing channel you maintain
• Every content format you produce
• Every partnership or collaboration
• Every recurring meeting or commitment
• Every tool or platform you pay for
• Every project that’s “in progress” but not shipped

How to do it: Open a spreadsheet. One row per activity. Columns for: Activity Name, Hours Per Week, Revenue Per Month, Strategic Importance (High/Medium/Low), Energy Impact (Energizing/Neutral/Draining).

Don’t estimate from memory — track actual time for one week if possible. If not, your best estimates will work, but be honest. Founders consistently underestimate time spent on low-value activities because they don’t want to see the number.

What you’ll find: Most founders discover 15-30 distinct activities consuming their time. Of these, typically 3-5 generate the majority of revenue and strategic value. The rest are fragments — leftover experiments, half-committed channels, obligations that made sense once but don’t anymore.

The founder I mentioned earlier had 23 distinct activities on her list. Twenty-three. No wonder nothing was growing.

Step 2: The Revenue-Per-Hour Analysis (Day 2)

Now we add financial clarity to the inventory. This step reveals which activities actually justify their time investment and which are quietly draining your most valuable resource.

What to do: For each activity on your list, calculate:

• Direct revenue per month: What does this activity directly generate? Be strict — only count revenue that clearly comes from this activity.
• Hours per month: How many hours per month does this activity consume?
• Revenue per hour: Direct revenue divided by hours.
• Trend: Is this activity’s revenue growing, flat, or declining over the past six months?

How to interpret the results:

Activities will naturally sort into four categories:

1. High revenue/hour, growing trend: Your core business. Protect and invest in these.
2. High revenue/hour, flat or declining trend: Mature activities that need attention — are they declining because of neglect or because the market is shifting?
3. Low revenue/hour, growing trend: Potential investments — might be worth more time if the growth rate justifies it.
4. Low revenue/hour, flat or declining trend: Subtraction candidates. These are the activities eating your time without sufficient return.

A critical note on indirect value: Some activities don’t generate direct revenue but support activities that do. Content marketing, for example, might generate zero direct revenue but drive 40% of your inbound leads. Account for this by noting “supports [activity]” in your analysis. But be honest — “this might lead to something eventually” is not the same as “this demonstrably supports revenue generation.”

When I ran this analysis on my own business in 2022, I discovered that two of my four content channels generated virtually no leads, despite consuming several hours per week. I was maintaining them out of habit, not strategy. Cutting them freed six hours per week with zero revenue impact.

Step 3: The Energy Audit (Day 3)

Revenue per hour isn’t the only metric that matters. Energy per hour matters too, because activities that drain you eventually degrade the quality of everything else.

What to do: Go back to your inventory and rate each activity on two dimensions:

• Energy impact: Does this activity give you energy (E+), drain your energy (E-), or have no effect (E0)?
• Competence level: Are you excellent at this (A), good (B), mediocre (C), or poor (D)?

The danger quadrant: Activities where you’re mediocre or poor AND that drain your energy are urgent subtraction candidates, regardless of revenue. You’re doing them badly and they’re making you miserable. Even if they generate some revenue, the indirect cost — in burnout, in quality degradation of your other work, in resentment — almost always exceeds the direct benefit.

The sweet spot: Activities where you’re excellent AND that energize you are your zone of genius. These should get the majority of your time and attention.

The delegation zone: Activities that drain you but that you’re good at are prime delegation candidates. Someone else can do them without the energy tax you’re paying.

This energy analysis reveals something spreadsheets alone can’t: the human cost of your activity portfolio. A business that maximizes revenue per hour but destroys the founder’s energy is not a sustainable business. The energy audit ensures your subtraction decisions account for sustainability, not just profitability.

Step 4: The Cut List (Day 4)

Now comes the hard part: deciding what to cut. The previous three steps gave you data. This step requires judgment.

The cut criteria: An activity should be cut if it meets two or more of the following:

1. Low revenue per hour with flat or declining trend
2. Energy-draining with mediocre or poor competence
3. Not demonstrably supporting a high-value activity
4. Someone else could do it better (and affordably)
5. You started it more than six months ago and it hasn’t reached meaningful scale

The process:

Sort your inventory by revenue per hour, lowest first. Starting from the bottom, evaluate each activity against the cut criteria. Mark it as:

• Cut: Stop doing this entirely. Not “do less of it.” Stop.
• Delegate: Keep the activity but remove yourself from it.
• Reduce: Decrease your investment by a specific percentage (not vaguely — define the reduction).
• Keep: This stays as-is or gets more investment.

Be aggressive. Most founders’ first cut list is too conservative. If you’re not slightly uncomfortable with how much you’re removing, you’re probably not removing enough.

The Kill or Commit framework applies here at the individual activity level: each activity either gets full commitment or full termination. The middle ground — keeping activities at insufficient investment levels — is the worst option.

A rule I use: If an activity has been “in progress” or “experimental” for more than six months without reaching escape velocity, it’s a cut. Six months is enough time to see signal. No signal after six months almost always means no signal ever.

Step 5: The Reallocation Plan (Day 5)

Cutting activities frees resources — time, energy, money, and attention. The final step ensures those freed resources go somewhere productive rather than dispersing into whatever is urgent that week.

What to do: Calculate the total hours and budget freed by your cuts. Then allocate them explicitly:

• What percentage goes to existing high-value activities? These are your winners. Giving them more resources should accelerate their growth.
• What percentage goes to one (maximum two) new experiments? Not five new experiments. One or two. With enough resources to give them a real test.
• What percentage goes to recovery? This is important and usually overlooked. After a subtraction, you may need rest, reflection, or time to restructure. Allocating 10-20% of freed time to recovery prevents the immediate reinvestment trap where you just replace old clutter with new clutter.

My reallocation from my 2022 audit:

I cut four activities (two content channels, a side product, and a partnership that was producing minimal results). This freed approximately twelve hours per week and about EUR 400 per month in tool costs.

Reallocation:

• Eight hours per week added to my consulting practice (existing winner)
• Three hours per week allocated to writing a book (new experiment)
• One hour per week kept as unstructured thinking time (recovery/reflection)

The result over six months: consulting revenue increased by about 35% from the additional investment. The book project produced a manuscript that became part of my content strategy. The unstructured hour produced two strategic insights that I wouldn’t have had if I’d immediately filled the time with work.

Running Your Own Subtraction Audit: The Quick-Start Version

If the five-day process feels like too much, here’s a condensed version you can do in two hours:

1. 30 minutes: List everything you’re doing. Everything. Don’t analyze — just list.
2. 30 minutes: For each item, write two numbers: estimated revenue per month and estimated hours per month. Calculate revenue per hour.
3. 30 minutes: Circle the bottom 30% by revenue per hour. For each circled item, ask: “If I stopped this today, what would actually happen in three months?” If the honest answer is “not much,” it’s a cut.
4. 30 minutes: For each cut, decide: stop entirely, delegate, or reduce. Reallocate the freed time to your top three activities by revenue per hour.

This condensed version isn’t as thorough as the five-day process, but it’s infinitely better than not doing an audit at all. And most founders who do the quick version end up wanting to do the full version because the results are so immediately valuable.

I recommend running a full Subtraction Audit annually and the quick version quarterly. The business constantly accumulates new activities — like a house accumulates clutter — and regular audits keep things focused.

The principle behind AI as a business tool applies here too: the goal isn’t to do more things. It’s to do the right things, better. Subtraction identifies the right things. Focused investment makes them better.

Key takeaways:

1. Start with a complete activity inventory — list everything that consumes your time or resources, and track actual hours for a week if possible.
2. Calculate revenue per hour for each activity and sort into four categories: high-revenue growing (protect), high-revenue declining (investigate), low-revenue growing (evaluate), and low-revenue flat (cut).
3. Add energy and competence ratings — activities that drain you and you’re mediocre at are urgent cuts regardless of revenue.
4. Apply the cut criteria: if an activity scores poorly on two or more of the five criteria, it goes on the cut list. Be aggressive — if you’re not uncomfortable, you’re not cutting enough.
5. Reallocate freed resources explicitly: 60-70% to existing winners, 20-30% to one or two new experiments, and 10-20% to recovery and reflection.
