How to forecast cash flow in Excel to stay on top of your business’s finances? It isn’t that difficult, and in this article, we will show you exactly how to do it.
Forecasting cash flow in Excel helps you estimate future cash inflows and outflows over a set period, helping you anticipate shortages, plan investments, and make data-driven decisions. Whether you’re a small business owner or a financial analyst, creating a cash flow forecast in Excel is essential for your financial planning.
What is Cash Flow Forecasting?
Cash flow forecasting is the process of estimating a business’s incoming and outgoing cash over a specific period. It’s a vital financial tool that helps businesses anticipate future cash needs, spot potential shortfalls in advance, and plan proactively for various scenarios.
By forecasting cash flow, companies can make more informed decisions and maintain financial stability.
Benefits for Businesses
Why is cash flow forecasting important for businesses?
Cash flow forecasting is essential for businesses because it helps them manage their cash flow projections effectively. By forecasting, businesses can ensure they have enough cash to cover expenses, meet financial obligations, and invest in growth opportunities.
Let’s look at each benefit more closely:
- Improved Financial Planning: Forecasts help align cash availability with upcoming expenses and goals.
- Early Risk Detection: Identifies potential cash shortages before they become critical.
- Smarter Decision-Making: Informs better choices with clear visibility into future cash flow.
- Better Budget Control: Compares forecasts with actuals to keep spending on track.
- Stronger Liquidity Management: Ensures cash is available to cover short-term obligations.
- Greater Business Agility: Enables faster response to market and financial changes.
Cash Flow Forecasting Methods
There are two main methods for cash flow forecasting: the direct method and the indirect method.
The direct method uses actual or expected cash inflows and outflows, like customer payments, salaries, and rent, to project short-term liquidity with high accuracy. In contrast, the indirect method starts with net income and adjusts for non-cash items and changes in working capital, making it better suited for long-term planning and financial reporting.
Both methods have their strengths, and the choice depends on your business needs and the time horizon you’re forecasting for.
How To Create a Cash Flow Forecast in Excel?
Let’s cut the fluff and dive into the practical how-to of creating a basic cash flow forecast in Excel. It involves inputting cash inflows and outflows, forecasting cash flow data for a specific period, and then calculating the net flow. Quite simple.
Here are the 5 straightforward steps on creating a cash flow forecast in Excel:
- Input cash inflow data
Make a table for inflow data. Enter all sources of incoming cash, such as sales revenue, investment income, loan proceeds, grants, and other income streams. Calculate total cash inflow with SUM formula.
- Input cash outflow data
Make a table for outflow data. Add expenses like operating costs, capital expenditures, loan payments, payroll, and taxes. Calculate total cash outflow with SUM formula.
- Calculate net cash flow
Subtract total outflows from total inflows to determine your net cash flow for the period. =SUM(total inflow) – SUM(total outflow)
- Forecast cash inflow & outflow data
You can make separate tables for inflow and outflow again, or put all data in one cash flow forecast projection table. Estimate future cash inflows and outflows based on trends, planned activities, or known upcoming transactions. Add them to your forecasting table.
- Calculate forecast net cash flow
Subtract forecasted total outflows from forecasted total inflows to find the projected net cash flow for the upcoming period. =SUM(total inflow) – SUM(total outflow)
What Excel Functions Are Used For Cash Flow Forecasting?
Excel is a powerful tool that can simplify accurate cash flow forecast projections. We showed you a basic cash flow forecast, but Excel also offers built-in forecasting functions that make it easier to perform more complex calculations. The functions include the previously used SUM and others, like IF, NPV, and IRR, which make complex calculations more efficient.
SUM Function for Cash Inflow and Outflow
The SUM function is used to add up a range of numbers in Excel, and it is the basis of your cash flow forecasting. This is the function we used in the how-to guide to calculate the total accurate cash inflows and outflows for the given period. By inputting the appropriate data into Excel, the SUM function can be used to quickly calculate the net cash flow and the net cash flow forecast.
IF Function to Forecast Changes
The IF function in Excel is used to perform calculations based on a specific condition. This function is particularly useful for forecasting changes in cash position based on changes in other variables. For example, you could use the IF function to calculate how an increase in sales revenue will impact your finances.

This function is particularly useful for businesses that need to evaluate the profitability of a particular investment. By calculating the NPV of an investment, you can determine whether it will generate a positive or negative return.
