How to Create an Operating Budget (With Examples)
Once you understand how an operating budget fits within the broader planning framework, the next step is building one that reflects both operational needs and financial discipline.
A strong operating budget translates strategy, resource requirements, and expected activity into a plan the entire organization can rely on throughout the fiscal year. The process is sequential, with each step creating the foundation for the next.
Step 1: Review Previous Year's Financials
Before you can plan forward, it's important to gain a grounded understanding of how the organization actually operated in the past. Start by studying the behavior of revenue and expenses to understand what’s stable, what fluctuates, and what consistently disrupts forecasts. A detailed look back gives you the evidence you need to build assumptions you can trust.
- Analyze prior-year revenue and expenses to establish a realistic baseline.
- Compare budgeted vs. actual performance to surface recurring gaps or overruns.
- Examine the timing of cash inflows and outflows to understand seasonality.
- Flag variances that repeat annually, since they reflect structural patterns, not anomalies.
Example: A mid-sized SaaS company pulls last year’s income statement and departmental reports. The finance team sees that customer renewals spike in Q2 and Q4, while cloud-hosting costs run higher than budgeted in months with large product releases. Those patterns become the starting point for this year’s assumptions.
Step 2: Forecast Revenue
A dependable revenue forecast is the backbone of an operating budget. This step involves translating what you know—past performance, pipeline activity, demand shifts—into what to expect. Revenue forecasting requires balancing optimism with discipline, because every spending decision in the budget depends on getting this number right.
- Use prior-year actuals as your starting point.
- Incorporate pipeline activity, retention rates, and upcoming initiatives.
- Factor in expected changes in demand, pricing, or market conditions.
- Reflect any known seasonal or cyclical patterns directly in the projection.
Example: At the same SaaS company, finance partners with sales and customer success to review the subscription pipeline, renewal dates, and planned upsell campaigns. They adjust last year’s revenue upward to account for a new enterprise product tier, while tempering expectations in a region where sales cycles are lengthening.
Step 3: Estimate Fixed, Variable, and Semi-Variable Costs
Once revenue expectations are set, you can model the operating costs required to support the business. This step focuses on understanding cost behavior—which expenses stay steady regardless of activity, which rise and fall with demand, and which have both components. Accurate expense modeling helps prevent budget shortfalls and makes future variances easier to diagnose.
- Identify fixed costs such as rent, insurance, and salaries.
- Determine variable expenses tied to output—materials, utilities, shipping.
- Break down semi-variable costs into their fixed and scalable components.
- Apply expected activity levels and use financial forecasting models to predict how each cost category will move.
Example: The SaaS classifies office leases, core SaaS tools, and base salaries as fixed. Cloud-hosting fees and payment-processing costs are modeled as variables, based on projected user activity and transaction volume. Support overtime and contractor spend are treated as semi-variable, rising in scenarios where customer growth exceeds the base plan.
Step 4: Incorporate One-Time and Non-Cash Expenses
Some expenses don’t occur regularly, while others don’t affect cash but do affect profit. If you leave these out, your budget won’t reflect the organization’s true financial performance. Including these expenses ensures leaders see the full picture—not just monthly spending, but the broader cost structure that shapes profitability.
Add planned one-time purchases such as equipment or system upgrades.
Include depreciation and amortization based on accounting schedules.
Capture major events affecting financials, like facility repairs or program launches.
Confirm all items align with financial reporting requirements.
Example: The SaaS company adds a planned customer data-migration project and a one-time security audit to the budget year. The team also updates depreciation schedules for recently purchased servers and capitalized software development, so the operating budget mirrors how these investments will appear on the income statement.
Step 5: Allocate Resources Strategically
This is where planning becomes operational. With revenue and cost projections in place, you can allocate funding across teams, programs, and priorities. The goal is to align resources with strategic direction, ensuring every part of the organization has what it needs without overcommitting.
Assign budgets to departments based on initiatives and workload.
Evaluate staffing needs, operating capacity, and upcoming commitments.
Use planning tools to model trade-offs and ensure allocations stay aligned.
Adjust distributions to maintain balance between priorities and constraints.
Example: At the SaaS company, leadership decides to shift more budget toward product and customer success to support a push into the enterprise market. Using their planning platform, they test different hiring and marketing scenarios, then finalize allocations that fund key initiatives while holding total operating expenses within the target margin.
Step 6: Review, Refine, and Secure Buy-In
A budget only works if the organization agrees to it and uses the finalized version. This last step turns the document into a shared plan by validating assumptions, confirming ownership, and setting expectations for how the budget will be monitored throughout the year.
- Share the draft with department leaders to validate assumptions.
- Incorporate insights that improve accuracy or reflect operational realities.
- Finalize the budget with clear alignment across functions.
- Revisit the plan regularly—often quarterly—to compare actuals to expectations and make updates as needed.
Example: Once the SaaS company has a consolidated budget, the finance team meets with each department head to walk through assumptions and trade-offs. After leadership signs off, they schedule quarterly review sessions where teams compare budget vs. actuals, explain variances, and agree on midyear adjustments.
