What is a Cash Flow Forecast?

A Cash Flow Forecast is a financial projection that estimates how much cash will come in and go out of your business over a future period (weekly, monthly, or annually). It helps determine whether your business will have enough cash to continue operating and avoid deficits.

A Cash Flow Forecast Calculator simplifies this process by providing an easy-to-use method to input data and generate your forecast automatically.


Why Use a Cash Flow Forecast Calculator?

  • Anticipate Shortages: Identify potential cash shortfalls before they become critical.
  • Better Planning: Make informed decisions about expenditures, investments, and hiring.
  • Control Over Finances: Gain visibility into your cash position for proactive management.
  • Support Loan Applications: Demonstrates financial planning to banks and investors.
  • Monitor Business Health: Track the effects of your business decisions on cash flow.

Formula Used in the Cash Flow Forecast Calculator

The general formula for calculating cash flow is:

Closing Cash Balance = Opening Cash Balance + Total Cash Inflows – Total Cash Outflows

Where:

  • Opening Cash Balance is the amount of cash at the start of the period.
  • Cash Inflows are the expected receipts such as sales, loans, or investments.
  • Cash Outflows are the anticipated payments such as salaries, rent, and bills.
  • Closing Cash Balance is the forecasted amount at the end of the period.

How to Use the Cash Flow Forecast Calculator

Here’s a step-by-step guide to using the tool:

Step 1: Choose a Time Period

Decide whether you’re forecasting weekly, monthly, quarterly, or yearly. Most businesses start with a monthly forecast.

Step 2: Enter Opening Cash Balance

Input the amount of cash your business currently has or expects to have at the beginning of the period.

Step 3: Add Expected Inflows

Include all sources of cash your business expects to receive, such as:

  • Sales revenue
  • Loan proceeds
  • Tax refunds
  • Investments

Step 4: Add Expected Outflows

List all anticipated expenses, such as:

  • Rent
  • Utilities
  • Wages
  • Loan repayments
  • Inventory purchases
  • Marketing expenses

Step 5: Calculate

The calculator automatically applies the formula:
Closing Cash = Opening Cash + Inflows – Outflows

Step 6: Review and Adjust

Evaluate the result to see if you’ll have a surplus or deficit. If negative, revise your strategy or plan for external funding.


Example Calculations

Example 1: Monthly Forecast

  • Opening Cash Balance: $5,000
  • Cash Inflows: $12,000 (sales) + $3,000 (loan) = $15,000
  • Cash Outflows: $4,000 (salaries) + $3,000 (rent) + $2,000 (utilities & supplies) = $9,000

Closing Cash Balance = $5,000 + $15,000 – $9,000 = $11,000

In this example, the business ends the month with a positive cash balance of $11,000.


Example 2: Negative Cash Flow Forecast

  • Opening Cash Balance: $3,000
  • Cash Inflows: $6,000
  • Cash Outflows: $10,000

Closing Cash Balance = $3,000 + $6,000 – $10,000 = -$1,000

Here, the business forecasts a $1,000 shortfall, indicating the need for additional funds or reduced spending.
