What Is a Business Budget?
Budgeting for a business is planning and tracking income and expenses.
It also involves setting financial limits and planning spending so that you have the resources to cover bills, payroll, and other expenses. Additionally, you should have revenue leftover to make a profit.
You’ve probably created a budget at home or may even be using one right now. You keep track of your income versus expenses, such as utilities, groceries, and a mortgage or rent payment.
The goal is the same: ensure you meet your required costs while having some left for savings.
A budget helps keep your company from overspending, which can cause serious trouble. According to data from the Small Business Administration, only half of small businesses survive for five years.
Poor financial planning, including a lack of budgeting, is one contributor to failure.

What Is a Business Forecast?
Forecasting for businesses is related to budgeting, but it’s more forward-thinking. It involves predicting future revenue and expenses.
You use data, trends, and business goals to accomplish this.
For example, your startup might be pulling in $10,000 per week at the moment, which is important for budgeting purposes. But a new competitor on the market or an economic downturn could change that.
You might forecast new revenue of $8,000 per week accordingly.
Conversely, you could be planning to expand your operation with a second location. Your forecast calls for an increase of $10,000, bringing the new total to $20,000 per month. The forecasted new income is based on data from past sales and historical trends within your company.
Trends can include weekly and monthly income over the past months or years. They can also utilize information such as company seasonal fluctuations and economic patterns that impact revenue.
The Key Differences Between Budgeting and Forecasting
What are the major differences between budgeting and forecasting?
In short, budgeting is more granular and about the present. In contrast, forecasting is broader and concerned with the future.
When you budget, you set a financial plan for the current conditions. You’re pulling in a certain number of dollars each month, so your expenses need to remain within that revenue limit. And your budget needs to account for any money you want to set aside for future growth or emergencies.
Forecasting, on the other hand, involves some level of prediction. Because forecasting isn’t as precise as budgeting, and because it extends further into the future, you may have to adjust course later.
Unpredictable factors can make your forecast go awry. Major events, such as natural disasters or wars, can impact your forecasting. Even personal things, like a family emergency or illness, can derail your plans.
It’s common for businesses to make two forecasts: a conservative one and a more aspirational version. If you are worried about a recession, say, you can use the more cautious forecast as your roadmap. But if the economy improves, you can lean in a less conservative direction.
Why Budgeting and Forecasting Are Critical for Small Businesses
By now, you can probably see how budgeting and forecasting go hand in hand. Without these tools, it’s much easier for a small business or startup to go under.
When used properly together, budgeting and forecasting can:
- Prevent overspending and ensure you meet your bills
- Prepare for slow seasons by saving money now
- Assist with hiring staff or opening new locations
- Guide growth and decision-making for the future
Well-executed budgeting and forecasting also help small businesses seeking investors or lender confidence. You may need to produce these plans when approaching venture capitalists or asking for a loan or line of credit.
5 Steps to Creating a Business Budget
How do you create a business budget? It’s much more straightforward if you see it as a series of logical steps.
Gather Your Financial Information
Start by getting all your financial information together in one place. If you use business software that integrates various functions, you may have it at your fingertips.
Otherwise, you’ll need to review bank statements, invoices, and bills. You need all the data about both accounts payable and receivable.
Make a Realistic Estimate of Business Revenue
Next, figure out how much income your company is pulling in each week or month. It’s probably not a consistent amount and will fluctuate over any certain time period.
But you can estimate an average based on deposits and payments over the most recent quarter or six months. And you can add any new customers you expect to contribute to your revenue in the near future.
Calculate Your Fixed Expenses
The third step is to know, to the dollar, what your fixed expenses are. These are payments that remain constant and are typically paid at fixed intervals—weekly, monthly, quarterly, or annually.
Quarterly or annual expenses can be averaged if necessary to provide a clearer picture of your monthly spending.
For instance, if you spend $1,200 per year in professional membership or licensing dues, you can say it’s $100 per month in this category.
Your bank statement or checkbook will jog your memory for these calculations.
They likely include:
- Rent or mortgage
- Phone and utilities
- Equipment rental
- Software or subscriptions
- Employee payroll
- Insurance policies
- Fixed business loans
- Website costs

List Variable Expenses
Variable expenses are those that change from one payment to the next.
Examples of these include:
- Credit card payments
- Overtime or commission
- Vehicle fuel and maintenance
- Office heating and cooling
- Packaging and shipping
- Raw materials and supplies
- Company taxes and fees
- Advertising and marketing
Determine If Any Changes Need to Be Made
The final step in preparing a budget is to tweak it if it’s not feasible or if it’s not helping you reach your goals.
For example, you may find that your expenses are too high for your income. This leaves you high and dry in emergency scenarios, with no money left to save for future growth.
There are two solutions here, which can be used alone or in combination. You can increase your revenue by attracting more customers or raising your rates. You can also cut expenses where possible.
How to Create a Forecast for the Year Ahead
Imagine you want to build a forecast for the coming year. Where do you start? Again, simply approach it step by step.
Write Down Your Goals and Plans
Begin by listing your goals and plans for the next year. Aren’t they the same thing? Actually, they’re a little different.
Your goals are a wish list for what you want to accomplish. Plans are more concrete action steps that might even already be going on. Think of goals as strategies and plans as tactics.
For example, a goal could be expanding into a neighboring town with a second office. A plan is renting the office, hiring staff, and adjusting the budget to hit this goal.
Examine How Your Budget Fits Into Your Ideas for the Future
As mentioned above, your budget has to facilitate your forecast to make it realistic. Sometimes that works in a positive direction, and sometimes not.
Expansion can bring in more income, but it also has increased expenses associated with it. How will you cover those costs until the customers are there?
Are there budget issues that could put a crimp in your future goals and plans? Do you need a new vehicle or expensive equipment? Maybe a staff member is going on leave or moving.
You’ll need budget documents to help with this step, such as:
- Profit and loss statements
- Cash flow statements
- Balance sheets

Look at Internal Patterns for a Bigger Picture
Next, examine company patterns over the last year or so. What do you notice?
- Has business steadily increased?
- Do you have seasonal fluctuations in income?
- Have your expenses gone up?
A good way to observe patterns is to graph these elements so you get the full picture with hard numbers.
Explore External Trends That Can Affect Your Business
Sometimes, there are events outside your control that you have to incorporate into your forecast.
What are economists predicting for your region or country? Will politics influence growth? What’s going on with your competitors?
Create a Plan A and a Plan B
Finally, consider making two business forecasts. Make one more conservative. The other a more generous prediction if everything lines up right.

Monitor and Adjust Regularly
It’s vital to remember that a budget and forecast are living documents. Most likely, they will need to be updated over time.
This is due to both internal and external factors. Often, things outside your control, like inflation or worker attrition, reshape your budget and forecast.
Set up a reminder to compare actual data to projections at regular intervals, such as monthly or quarterly. Then adjust as needed to stay on track.
Jumpstarting Your Small Business Budget and Forecast
- If your business is new, budgets and forecasts are key parts of your larger business plan. So it’s a win-win when you complete them, as it will help with tasks like getting loans and credit.
- Many small business owners find it helpful to hire an accountant to assist with some elements. A popular outsourced task is putting together a profit and loss statement.
- Your budget isn’t just a list of what you’ve earned and spent after the fact. It should function as a set of limits on the expense side in order to remain solvent. Ensure that everyone in the company adheres to the budget for purchases and is aware of the associated limitations.
- The more you can integrate your financial functions, the easier it is to operate. For instance, use invoicing software, like Invoice Simple, that includes expense tracking and profit margin calculation. This will make creating budgets and forecasts simpler and faster.
