Business Profit and Owner-Hours Workbook

A business can report $6,000 a month in profit while buying its owner a demanding part-time job. That can still be worth owning. The mistake is paying as if the labor comes free with the website.

This workbook is fully available below. Copy it into a document or spreadsheet, or print the page. You do not need to send us figures, join a list or book a call.

Use it when: you are checking a listing, preparing your own earnings record for sale, or deciding whether to keep doing the work. Do not use it as: audited accounts, an appraisal, a lender's debt-service calculation or an estimate of your tax bill.

Business Profit and Owner-Hours Workbook: the three outputs

Build three separate outputs: normalized operating earnings, a coverage plan for the work, and cash left after the costs of your chosen ownership plan. None substitutes for the others. A profitable operation can still need cash it has not yet collected.

Start with these controls before adding numbers:

Do not mix a good revenue month with a low-cost month to manufacture a “normal” result. Use one consistent period, then show recent changes separately.

Step 1: rebuild the profit from the records

Start with the reported profit and make every correction visible. Each adjustment needs a source, a reason and a repeatability judgment. Keep a rejected adjustment in the record so it does not sneak back into a later calculation.

“SDE” means seller's discretionary earnings, a measure often used to discuss an owner-operated business. Definitions and adjustments can differ across listings. This workbook does not declare that its result is a broker's SDE or an accountant's EBITDA. Get the exact bridge from the reported accounts to whatever metric is being quoted.

A seller's wage already recorded in the accounts needs separate treatment if it is proposed as an add-back. If removing it also removes the person doing essential work, include the cost of replacing that work in your ownership plan. Do not assume the entire wage disappears from the economics.

The adjustment test

An expense is not removable just because the next owner plans to stop paying it. If stopping it is likely to damage the revenue being sold, you are changing the business, not simply cleaning its accounts.

Step 2: log the work people forget to count

Log tasks as they happen for several representative weeks, then check seasonal and exceptional work separately. Four weeks is a useful starting diary, not proof of the entire year. A quiet month misses launches, renewals, tax preparation, software updates and supplier problems.

Count the work of owning the work: checking quality, assigning tasks, paying people and deciding what happens next. Count the quick inbox checks if they interrupt your day. “Only 15 minutes” four times is still an hour.

Separate availability from active work. A software business might need six hours of tickets and changes in a quiet week but require someone who can respond to an outage. A contractor's hourly quote may not include that availability.

Field Notes — Operator experience: the owner often supplies judgment that does not appear in a task list. Which affiliate offer is still worth recommending? Which customer complaint points to a bug? Which book ad should be stopped? A handover can document the process; it does not instantly give another person the same judgment. Price training, oversight and a period of learning.

Cover the exceptions without inventing a universal buffer

Ask for actual examples from the previous year. If no records exist, mark the estimate as a User assumption and show a range of hours rather than pretending the listing's number is complete.

Do not add a generic 20% to every line and call it verified. A clearly labeled assumption is better than a precise-looking invented fact.

Step 3: price the uncovered tasks, once

Price the work by task and required skill, using actual scope and quotes where possible. A writer's rate does not price security response, bookkeeping or founder-level product decisions. A single blended hourly rate can illustrate the calculation but rarely completes the hiring plan.

Use a rate that includes the costs relevant to the engagement, such as employer costs, agency markup or minimum retainers. An hourly figure without a minimum-hours commitment can understate the actual bill. Currency and location also matter.

A task already done by a paid contractor stays in the expense line. If the contractor leaves, subtract only the additional cost of replacement above the cost already recorded. If you subtract the full new invoice while retaining the old invoice in costs, you have counted the same job twice.

A completed example: $72,000 profit and a 12-hour week

Every number below is fictional (User assumption). It illustrates a small online operation and does not describe one of our businesses or a completed acquisition.

The seller's accounts show $120,000 of net revenue and $48,000 of operating costs for October 2025–September 2026. Those costs already include $12,000 for contractors. The owner takes no wage through the books. A $2,400 one-time migration expense is included in the recorded costs; a recurring $3,600 software bill was paid personally and omitted.

Here is the fictional four-week owner diary. The annualization below assumes it is representative; that assumption remains open until seasonal and exceptional work is checked.

48 hours ÷ 4 weeks = 12 hours/week. At 52 weeks, that is 624 hours/year. At an assumed loaded replacement rate of $35/hour, covering all those tasks costs $21,840/year, or $1,820/month. That is illustrative pricing, not a hiring quote.

The loan line is total scheduled cash payments in this illustration. It assumes no acquisition-loan interest was already deducted in the earnings bridge. If it was, adjust the bridge with your accountant before subtracting the payment, so you do not deduct interest twice. Principal repayments affect cash but are not simply another operating expense.

The $300 is an assumed increase in cash tied up by operations, not a second deduction of ordinary bills already in the accounts. No inventory purchase is added here. If your business holds stock, reconcile product expense, stock bought at closing and later stock investment separately.

The $12,000 of existing contractors is still inside the original $48,000 cost line. It is not deducted again. The buyer also assumes two hours a week of oversight after hiring. That is time the buyer must accept, not another cash wage deducted from the table.

If the buyer needs $3,000/month, this plan does not fit: $2,880 is $120 short. Taking an expense out of the spreadsheet does not resolve it. Changing a supported assumption, financing arrangement or requirement might; the revised result needs its own record.

What if revenue falls 15%?

Stress revenue and costs separately. Do not assume every cost drops at the same rate as sales.

For a simplified downside, assume all costs in this example stay fixed over the stress period. Revenue falls from $120,000 to $102,000, an $18,000 annual reduction. Normalized earnings become $52,800; after $21,840 labor coverage, $10,800 debt cash payments and $3,600 extra running capital, cash is $16,560/year, or $1,380/month before personal tax. This is a scenario, not a forecast.

If some costs truly fall with revenue, model those changes using evidence. If support hours or advertising must rise to recover revenue, show that too.

Record AI savings as a tested task, not a percentage of profit

AI may save time on a task without reducing the cash needed to operate the business. If the owner still does the work and no paid hours disappear, the immediate saving is time. If a retainer stays unchanged, the cash bill stays unchanged too.

Use this record for a real task:

A fictional trial: a four-hour weekly task becomes 2.5 hours of production plus 0.5 hours of checking. The saving is one hour/week, not 1.5. At $35/hour and 52 weeks, that is $1,820/year of potential labor cost. Add $360/year of software and the potential net is $1,460, or about $121.67/month. Count it as cash only if that paid cost actually disappears and the result holds across representative tasks. Otherwise record time saved and keep the earnings calculation unchanged.

My preference is to buy a business that works before the AI improvement. Then the improvement is a bonus you earn, rather than a story you paid the seller for.

The completed Deal Decision Check

Make the final decision against your own requirements. A useful workbook can say “does not fit” without saying the business is worthless.

If you are selling, a clear record may expose work you can document or delegate before listing. If you are buying, it may show that a smaller business with different work fits better. Both are more useful than a bigger “passive profit” number.

When your earnings and work plan are supported, the next choice is how much help you want with the transaction. The marketplace comparison shows who does what. We do not collect your workbook or review individual deals.
