How to Build Next Year’s Budget, Step by Step

A budget is a plan expressed in numbers. It tells you how much you expect to earn, how much you plan to spend and what should be left over. For a small business, it does not need to be elaborate, but it does need to be grounded in reality and used throughout the year. Late October and November are a good time to build one, so January starts with a plan in place.

Step 1: Start with this year’s actuals

Pull a profit and loss statement for the year to date and estimate the remaining months. This gives you a baseline for every line item. Look for patterns, such as which months were strong or weak, and for one-time events that should not repeat. Note costs that rose during the year, since they will likely carry forward.

Step 2: Set clear goals

Decide what you want next year to accomplish before filling in numbers. Do you want to grow revenue, improve margins, hire, open a new location or build a cash reserve? Goals shape the budget. A business planning a major hire needs a different budget from one focused on paying down debt.

Step 3: Forecast revenue from the bottom up

Rather than simply adding a percentage to this year’s sales, build revenue from its drivers: number of customers, average sale, purchase frequency and retention. Break it down by month, because seasonal patterns affect cash. Be conservative. It is easier to adjust upward than to scramble when sales lag.

Step 4: Plan expenses in categories

Divide costs into groups that are easy to manage:

• Cost of goods or services. Costs that rise with sales, such as materials or direct labor.
• Payroll. Salaries, wages, payroll taxes, benefits and planned raises or hires.
• Fixed overhead. Rent, insurance, utilities, software and professional fees.
• Growth investments. Marketing, equipment, training and new projects.
• Contingency. A cushion for the unexpected.

Review recurring expenses line by line. Subscriptions and services tend to accumulate quietly, and a few minutes of questioning each one can free up money for priorities that matter more.

Step 5: Test, adopt and track

Compare projected revenue with planned expenses and see what remains. If the result falls short of your goals, revisit pricing, costs or timing. Build a cautious version alongside the expected one, so you know in advance what you would cut if revenue disappoints. Then turn the budget into a cash forecast, since profit and cash rarely move at the same time.

Once the year begins, compare actual results to the budget every month. Investigate significant differences and adjust as you learn. A budget is a tool for making decisions, not a test you pass or fail. Your accountant or financial advisor can review your assumptions and help you plan for taxes, financing and major investments.
