Costs
Building clear profit and loss forms
Learn how to structure profit and loss forms, separate direct costs from operating expenses, choose columns, and make a P&L easier to read month to month.
A profit and loss form is an argument laid out vertically. Well-built profit and loss forms start with what came in, subtract things in a deliberate order, and end with what is left. The order is the whole point. Rearrange it and you still have the same numbers, but you can no longer tell where the money went.
This page covers the form's shape, why its lines sit in that sequence, and how to set up columns so it reads month to month. It also covers layout choices that decide whether anyone acts on it.
The U.S. Small Business Administration's notes on managing business finances explain what the form is for in the wider run of a business.
What to take away
- The two subtotals in the middle carry the argumentgross profit asks whether the work is priced right, operating profit whether the business is the right size for the work.
- Add a percent-of-revenue column before anything else. It is the cheapest column on the form and the one that shows drift.
- Write your direct-versus-operating rule down beside the form. Consistency matters more than which way you decide.
The reading order
Every P&L makes the same descent, whatever the labels:
- Start with revenue streams, then subtract returns, credits, and discounts to get net revenue.
- Subtract direct costs from net revenue to get gross profit; calculate gross margin as gross profit divided by net revenue.
- Subtract operating expenses from gross profit to get operating profit.
- Show interest and non-recurring items separately so readers can distinguish them from ordinary operations.
- Show an income-tax line only when it applies to the business and the purpose of the form.
- Arrive at net profit after the applicable items below operating profit.
Use those labels consistently, even if your accounting software uses different names.
The P&L descent
- Revenue: what you earned from customers
- Direct costs: cost to deliver that revenue
- Gross profit: what the work throws off
- Operating expenses: cost of the business existing
- Operating profit: what the operation throws off
- Below the line: financing and one-offs
- Net profit: what is left
The two subtotals in the middle are the reason to build the form this way. Gross profit answers "is the work priced right?" Operating profit answers "is the business the right size for the work?" A single revenue-minus-expenses number answers neither, and that is exactly the form most people start with.

The line that decides everything: direct or operating?
The split between direct costs and operating expenses is where most homemade P&Ls fall apart, because it is a judgment call and people make it differently each month.
Direct or operating cost?
If you sold nothing next month, would this cost disappear?
direct cost
operating expense
The test that holds up: if you sold nothing at all next month, would this cost disappear? If yes, it is direct. If it arrives regardless, it is operating.
Worked through a few awkward cases:
Direct or operating?
- A salaried designer who bills clients is usually direct, because their time is the product, but if they are paid the same whether or not work comes in, some businesses treat the base salary as operating and only the overtime as direct. Either is defensible. Pick one and never switch mid-year.
- Payment processing fees are direct. They scale exactly with revenue.
- The subscription that runs your whole business is operating. The per-seat license you buy specifically for one client project is direct.
- Rent is operating, even in a business where the space is where the work happens.
- Shipping you pay is direct. Shipping you charge the customer is revenue, and should appear as its own revenue line rather than netted off.
Write your rule down next to the form. The consistency matters more than the choice, because the number people act on is the trend, and a reclassification breaks the trend without anyone noticing. The same discipline applies to the paperwork behind each sale, where invoices and receipts keep the fields that survive contact with reality.
Columns, not just rows
A single column of figures for one month is almost useless: the reader has no idea whether a number is good. The column layout is what turns the form into information.
Which columns to add
Column set
- This period only
- What happened
- This + prior period
- Which way moving
- This + last year
- Real or seasonal
- Actual + budget + variance
- On plan?
- Actual + % of revenue
- Cost shape drifting
- Year to date
- Where year lands
What it answers
- This period only
- Almost never alone
- This + prior period
- Monthly review
- This + last year
- Any seasonal business
- Actual + budget + variance
- Once plan exists
- Actual + % of revenue
- Every time
- Year to date
- Alongside period columns
When to use
- This period only
- This + prior period
- This + last year
- Actual + budget + variance
- Actual + % of revenue
- Year to date
What it answers
- This period only
- What happened
- This period + prior period
- Which way things are moving
- This period + same period last year
- Whether a change is real or seasonal
- Actual + budget + variance
- Whether you are on plan
- Actual + % of revenue
- Whether the cost shape is drifting
- Year to date
- Where the year will land
When to use it
- This period only
- Almost never on its own
- This period + prior period
- Monthly management review
- This period + same period last year
- Any business with a season
- Actual + budget + variance
- Once you have a plan worth measuring against
- Actual + % of revenue
- Every time: this is the cheapest column to add
- Year to date
- Alongside the period columns, never instead
For a month-to-month form, place the line-item names first, followed by the current month, the comparison month, the dollar variance, and the current-month percent of net revenue. Calculate dollar variance as current-month amount minus comparison-month amount, and calculate percent of revenue as the line amount divided by net revenue. Keep the periods labeled and use the same variance direction throughout the form.
The percent-of-revenue column deserves the emphasis. Costs in currency go up when you grow, which tells you nothing. Costs as a share of revenue reveal the thing you actually want to know: whether growth is making the business better or just bigger.
Cash basis or accrual basis
State the basis at the top of the form, because the same business produces two different pictures depending on the answer.
Cash versus accrual basis
Basis
- Cash
- When money moves
- Accrual
- When work happened
When a line lands
- Cash
- Matches bank, lies on timing
- Accrual
- More about business, less bank
What it tells you
- Cash
- Accrual
On a cash basis, a line lands when money moves. It is simple, it matches your bank, and it lies about timing: a quiet month where a large customer happened to pay looks like a good month.
On an accrual basis, a line lands in the period the work happened or the cost was incurred, regardless of when money moved. It tells you more about the business and less about your bank balance, which is why a P&L on this basis has to be read next to a cash flow view rather than instead of one.
A template cannot settle which basis you may or must use for tax reporting. It depends on your jurisdiction, your size, your legal structure, and sometimes an election you made at registration. For U.S. federal tax accounting methods, IRS Publication 538, Accounting Periods and Methods, explains relevant rules; check which method applies to your business.
The records you must keep depend on where you file. The UK guidance on company and accounting records applies to UK companies; U.S. businesses can consult IRS Publication 583, Starting a Business and Keeping Records, for federal tax recordkeeping guidance.
Ask your accountant before you decide, and ask your accountant again before you change. Switching bases mid-stream makes every comparison in the form meaningless until a full year has passed.
The tax line depends on the business structure and the purpose of the form. For a sole proprietor, business profit is generally reported on Schedule C (Form 1040); federal income tax on the owner's total income is not a Schedule C business expense, and self-employment tax is figured separately on Schedule SE. A C corporation reports on Form 1120, which computes taxable income and federal income tax under corporate rules; taxable income can differ from book net profit. An S corporation files Form 1120-S and generally passes income through to shareholders. Do not treat a generic tax line as an automatic deduction from operating profit; include it only when appropriate to the entity and reporting purpose.
Categories that should never collapse into one line
A form with a "miscellaneous" line as one of its largest expenses is a form nobody can act on. Some specific splits earn their keep:
- Keep materials, delivery labor, subcontractors, and per-transaction costs distinct when they help explain what it costs to deliver the work.
- Separate salaries and related costs from contractors and professional fees when those costs behave differently or need different oversight.
- Keep premises, software, marketing, travel, insurance, and equipment or depreciation identifiable rather than burying them in “other.”
- Show interest and one-off items separately from recurring operating expenses so they do not obscure the ordinary cost of running the business.
Use only the splits that help someone understand or act on the form, but do not combine unlike costs into a large miscellaneous line.
Splits that earn their keep
- Separate people costs by function, not contract type
- Separate recurring software from one-off tools
- Separate marketing spend from sales cost
- Give any dominant supplier its own line
- Keep one-off items out of operating entirely
Making the form readable
Small formatting choices decide whether anyone uses it:
- Put the business name, period covered, and accounting basis at the top, and label every comparison column with its period.
- Indent detail lines under section headings and make subtotal rows, including gross profit, operating profit, and net profit, easy to spot.
- Align amounts consistently, use the same currency and number format throughout, and show expenses in parentheses if that is the form's chosen convention.
- Keep labels concise and consistent from period to period so readers can compare lines without guessing whether a category changed.
- Leave enough space for longer labels and notes, and avoid letting formatting obscure the figures or subtotals.
Readability rules
- Negative numbers in brackets, one style
- Subtotals visually distinct from lines above
- One rounding rule for the whole form
- Summarize long sections, detail in schedule
- Period and basis in header on every page
- Date and author at the foot
Checks before you circulate it
- Does net revenue reconcile to what you actually invoiced or collected in the period?
- Is every cost in exactly one placeno cost sitting in both direct and operating?
- Did any category move sharply as a share of revenue? If so, is the cause a real change or a reclassification?
- Are there any period-end costs that arrived after the cut-off and belong in this period?
- Does the gross margin look like the margin you think you sell at? A gap between the two is usually the most valuable thing the form will tell you.
- Is anything in the operating section a one-off?
- Can someone who was not involved read it top to bottom and say what happened?
If the gross margin on the form does not match the margin you thought you were selling, the gap usually starts in how the work was priced. See quotes and estimates.
Pre-circulation checks
- Net revenue reconciles to invoiced or collected
- Every cost sits in exactly one place
- Sharp category moves explained by change or reclassification
- Period-end costs after cut-off included
- Gross margin matches the margin you sell at
- Nothing in operating is a one-off
- An uninvolved reader can say what happened
Circulating the form outside the business is a covering-note problem as much as an accounting one. The rules are in business letters.
