How to create a budget for your small business

Creating a small business budget can help you to gain a clearer understanding of where your money is coming from, where it is going, and whether you are on track to achieve your financial objectives. This comprehensive view of your finances can allow you to make more confident decisions, prepare for quieter periods, manage unexpected costs, and identify opportunities to invest in your business.

Read our guide below to learn what a business budget is, why it matters, and how to create one with our free small business budgeting template to help you get started.

What is a business budget?

A business budget is a financial plan that estimates your income and expenses over a set period, such as a month, quarter, or year. This can help you to understand how much money you expect to bring into your business, what you need to spend to operate successfully, and whether you are likely to make a profit.

For small businesses and self-employed professionals, a budget can provide a clearer picture of financial health and help support better decision-making.

Why is budgeting important for small businesses?

Better cash flow management

A budget helps you plan for regular costs and identify periods where cash flow may be tighter than expected.

More informed business decisions

When you understand your financial position, it can be easier to decide whether to invest in equipment, hire staff, increase marketing activity, or expand your services.

Greater financial resilience

Unexpected costs and changing market conditions can affect any business – budgeting can help you to build contingency funds and prepare for uncertainty.

Easier goal setting

A clear budget can provide you with realistic financial targets and help you to track progress throughout the year.

What should a small business budget include?

A small business budget should typically include all income and expenditure over a given period, covering:

• Total income
• Fixed costs
• Variable costs
• Tax provision
• Emergency fund
• Planned savings
• Expected profit/loss

How to create a small business budget

1. Review your income

Look at previous sales figures. However, if you are a new business, you can estimate your income based on realistic sales forecasts.

2. List your business expenses

Record both fixed and variable costs so you can understand your ongoing financial commitments.

3. Allow for tax and compliance costs

Ensure you set aside funds for tax obligations and any professional fees required to run your business.

4. Build in a contingency fund

Unexpected expenses can arise at any time, so having a financial buffer can help to prevent short-term issues becoming long-term problems.

5. Track and review regularly

Monitoring your budget regularly can help you to identify trends and make adjustments before issues arise.

Frequently asked questions about small business budgeting

How often should a small business budget be reviewed?

As a minimum, small business budgets should be reviewed monthly. However, businesses experiencing rapid growth or seasonal fluctuations may benefit from reviewing their budget more frequently.

Can I use a spreadsheet as a business budget?

Yes, many small business owners and self-employed professionals use spreadsheets to manage their budgets. A spreadsheet can help you record income and expenses, track spending patterns, monitor cash flow, and review progress against your financial goals. Our small business budgeting template provides a simple framework to help you get started.

What is the difference between a budget and a cash flow forecast

A budget helps you plan your expected income and expenditure over a set period, while a cash flow forecast focuses on when money is expected to enter and leave your business.

Should a small business have an emergency fund?

Many businesses find it helpful to maintain a contingency reserve to help manage unexpected costs. Having a financial buffer can provide greater resilience and help businesses to navigate unexpected financial challenges without impacting day-to-day operations.
