An operating budget is a company's plan for revenue and day-to-day operating costs over a fiscal year, usually phased by month or quarter and split by department. It ends at operating income. Capital purchases, debt and financing sit in separate budgets, and the operating budget becomes the baseline that monthly actuals are compared against.
Most definitions on this search were written for retailers, restaurants or city governments. A software company's operating budget has a different shape: almost no materials, a cost base that is mostly people, and revenue that depends on bookings signed months earlier. This entry shows what goes into an operating budget for a B2B SaaS company, how it differs from the capital budget, the cash budget and the annual operating plan, a quarterly example with every number shown, and the flexible budget check that tells you whether a miss was spending or volume.
What goes into an operating budget
An operating budget runs from revenue down to operating income. Everything above that line is in it. Interest, taxes, capital purchases and financing are not.| Section | What it plans | Main driver in a SaaS company | Usual owner |
|---|---|---|---|
| Revenue budget | Subscription and services revenue by month | Bookings forecast, start dates, renewals and churn | CFO or FP&A, with the CRO |
| Cost of revenue | Hosting, support, implementation, payment fees | Customers, usage and services hours | Finance with engineering and support |
| Sales and marketing | Sales and marketing salaries, commissions, programs, events, tools | Headcount plan, quota capacity, pipeline target | CRO and CMO |
| Research and development | Engineering and product salaries, contractors, dev tools | Product roadmap and team size | CTO or VP Engineering |
| General and administrative | Finance, HR, legal, rent, insurance, company software | Headcount and contracts | CFO |
| Operating income | Revenue minus all of the above | The result, not an input | CFO |
Operating budget vs capital budget, cash budget, AOP and forecast
The operating budget is one of several plans finance runs at the same time. They use the same revenue number and answer different questions.| Plan | Question it answers | Time frame | Where it lands |
|---|---|---|---|
| Operating budget | What will we earn and spend running the business this year? | Fiscal year, by month or quarter | Income statement, down to operating income |
| Capital budget | Which long-lived assets will we buy or build? | Multi-year, by project | Balance sheet, then depreciation in the operating budget |
| Cash budget | Will we have enough cash each month? | Months or weeks | Cash balance and runway |
| Annual operating plan | What are the targets, quotas, hires and budget for the year? | Fiscal year | The board-approved plan; the operating budget is its financial part |
| Sales budget | What will sales book and what will the sales team cost? | Fiscal year | Feeds the revenue line and the S&M line |
| Forecast | What do we now expect to happen? | Rest of the year, updated monthly or weekly | Compared with the budget each month |
Operating budget example: a SaaS company planning $20.2M of revenue
The example is illustrative: a B2B SaaS company with a 78% gross margin that plans to reach a small operating profit by the second half. Figures are in thousands of dollars.| ($000) | Q1 | Q2 | Q3 | Q4 | Year | % of revenue |
|---|---|---|---|---|---|---|
| Revenue | 4,600 | 4,900 | 5,200 | 5,500 | 20,200 | 100.0% |
| Cost of revenue | 1,012 | 1,078 | 1,144 | 1,210 | 4,444 | 22.0% |
| Gross profit | 3,588 | 3,822 | 4,056 | 4,290 | 15,756 | 78.0% |
| Sales and marketing | 1,900 | 2,000 | 2,050 | 2,050 | 8,000 | 39.6% |
| Research and development | 1,150 | 1,200 | 1,200 | 1,250 | 4,800 | 23.8% |
| General and administrative | 630 | 640 | 660 | 670 | 2,600 | 12.9% |
| Operating income | -92 | -18 | 146 | 320 | 356 | 1.8% |
- Costs are front-loaded and revenue is back-loaded. Sales and marketing rises in Q2 because the new reps start early in the year. They do not produce at full quota until much later, so the first half loses money even though the year is profitable. - The revenue line carries the whole plan. Each quarter's revenue comes mostly from bookings signed in earlier quarters. If Q1 and Q2 bookings come in light, Q3 and Q4 revenue fall short too, while the costs are already committed. - The S&M share is high but not unusual for a growth plan. Benchmarkit's 2025 SaaS benchmarks report that private companies above $100M ARR invest a median 33% of revenue in sales and marketing, the same as public SaaS companies. A smaller company growing faster often spends more than that.
How to build an operating budget in seven steps
Start from revenue, price the people, add everything else, then phase it by month. In order:1. Set the revenue budget from the bookings plan. Turn quarterly bookings targets into monthly revenue with start dates, renewals and expected churn. Build it from rep capacity, not from a growth percentage. The sales budget guide walks through the capacity math. 2. Build the headcount plan. List current employees and planned hires by team and start month, with backfills for expected attrition. The headcount planning template lays this out by quarter. 3. Price each role fully loaded. Salary, variable pay at target, employer payroll taxes, benefits and tools. A plan that budgets salaries only understates the people line. 4. Add non-people costs by department. Hosting and support in cost of revenue, programs and events in marketing, software, rent and insurance in G&A. Use signed contracts where they exist. 5. Separate fixed and variable lines. Mark which costs move with revenue (commissions, payment fees, hosting usage) so the budget can flex later. 6. Check the shape. Gross margin, S&M, R&D and G&A as a percent of revenue, operating margin by quarter, and cash runway. If the first half burns more cash than the company has, change the hiring dates, not the revenue line. 7. Approve, lock and track. Once the board approves it, the budget stays fixed for the year. Changes go into the forecast, and each month closes with a budget vs actual review.
Static vs flexible operating budget
A static budget stays at the planned volume. A flexible budget restates costs at the volume you actually reached. The flexible version answers a question the static one cannot: was the miss caused by spending or by revenue?Take Q4 from the example above (illustrative). The static budget plans $5,500,000 of revenue and $320,000 of operating income. Assume variable costs are 8% of revenue in cost of revenue (hosting usage and payment fees) and 9% of revenue in commissions.
| Q4 ($000) | Static budget | Flexible budget at actual revenue | Actual |
|---|---|---|---|
| Revenue | 5,500 | 4,950 | 4,950 |
| Variable costs (17% of revenue) | 935 | 841.5 | 841.5 |
| Fixed costs | 4,245 | 4,245 | 4,288.5 |
| Operating income | 320 | -136.5 | -180 |
- Volume variance: -$456,500. The flexible budget's -$136,500 against the static budget's $320,000. This is what the revenue shortfall cost, after the variable costs that fell with it. - Spending variance: -$43,500. Actual -$180,000 against the flexible budget's -$136,500. This part is overspending on fixed costs.
Most of the miss is revenue. Cutting $43,500 of spending would not fix it. Better bookings would. For the variance formulas, see variance analysis.
What goes in an operating budget template
A usable operating budget template has one tab per input and one summary tab. The inputs: a revenue tab built from bookings, a headcount tab with start dates and fully loaded cost, a non-people tab by department and month, and an assumptions tab with the variable cost rates. The summary rolls them into the P&L down to operating income, by month and quarter, with percent of revenue next to each line.Three ORM templates cover this. The annual operating plan template builds the full-year plan from ARR targets, rep capacity, headcount and budget. The rolling budget guide and template keep a 12-month budget rolling forward each month. The profit and loss template tracks actuals in the same layout, so budget and actual line up row for row.
What Pete Furseth sees in operating budgets
Pete Furseth, ORM's COO, works on the sales capacity side of the budget, the biggest variable in most SaaS plans.
- Hiring has to come before the revenue. "Capacity has to be created before the business needs it" (ORM insight board, q40). A rep hired in January rarely adds productive capacity by March, so the budget has to carry the cost early. - The sales cost line is the biggest lever. Pete reports that ORM's optimized capacity models typically find 10% to 15% lower sales cost for the same bookings target, or 10% to 15% more productive capacity for the same sales budget (q40). Results depend on the company. - Plan two years, budget one. Moving from a one-year to a two-year capacity plan reduces cost by roughly 5%, as a rule of thumb from the same models (q40). The budget is still annual, but the hiring dates in it come from a longer view.
Common operating budget mistakes
- Starting from last year plus a percentage. It copies last year's mistakes and ignores what changed. Start from the bookings plan and the headcount plan. - Budgeting salaries instead of fully loaded cost. Employer taxes, benefits and tools are a large share of the people line, and they are often left out. - Hiring on day one of the quarter. Real start dates slip. Use realistic start months, or the budget will show savings that are really late hires. - Ignoring ramp. A new rep costs a full salary from day one and carries a full quota much later. Revenue should follow the ramp, not the hire date. - Treating the budget as the forecast. The budget is the fixed baseline. Update the forecast monthly and leave the budget alone, or there is nothing to measure against. - No flexible view. Without a flexible budget, every revenue miss looks like a spending problem.
Planning with ORM
Every line in a SaaS operating budget depends on the revenue line, and the revenue line depends on the bookings forecast. ORM builds bookings and ARR forecasts and capacity models for B2B SaaS companies from CRM and finance data, so the budget's revenue and hiring plan start from the same numbers. ORM targets 95% forecast accuracy.

Frequently Asked Questions
What is an operating budget?
An operating budget is the plan for a company's revenue and day-to-day operating costs for the coming fiscal year. It covers revenue, cost of revenue and operating expenses such as sales and marketing, R&D and general and administrative, usually by month or quarter and by department. It ends at operating income. Capital purchases, loan payments and financing are planned in separate budgets.
What is the difference between an operating budget and a capital budget?
The operating budget plans the costs of running the business this year, such as salaries, hosting, rent and marketing, which hit the income statement as they are incurred. The capital budget plans purchases of long-lived assets, such as equipment, buildings or capitalized software, which go on the balance sheet and are depreciated or amortized over several years. Depreciation of those assets then shows up in the operating budget.
What are the main parts of an operating budget?
Most operating budgets have four parts: a revenue budget, a cost of revenue budget, operating expense budgets by department (sales and marketing, R&D, general and administrative) and the resulting operating income line. In each department the biggest line is usually headcount, so the headcount plan and its fully loaded cost sit underneath the expense budgets.
What is an example of an operating budget?
An illustrative B2B SaaS company plans $20.2 million of revenue for the year, $4.4 million of cost of revenue, $8.0 million of sales and marketing, $4.8 million of R&D and $2.6 million of G&A. That leaves $356,000 of operating income, a 1.8% operating margin. Phased by quarter, the company loses money in Q1 and Q2 and makes it back in Q3 and Q4 as revenue grows faster than costs.
Is an operating budget the same as an annual operating plan?
They overlap but are not the same. The annual operating plan is the full plan for the year: revenue targets, quotas, headcount, the budget and the key initiatives, approved by the board. The operating budget is the financial part of it, the revenue and expense numbers that finance tracks every month. Many companies use the two terms loosely, so check what a given document includes.
What is a flexible operating budget?
A flexible budget restates the costs you would expect at the volume you actually achieved, instead of the volume you planned. Fixed costs stay as budgeted, and variable costs such as commissions, payment fees and hosting usage are recalculated at the actual revenue. Comparing actuals with the flexible budget separates a spending problem from a volume problem.
