How Do I Create A Cash Flow Forecast?

As discussed in my previous blog, cash flow forecasting is a key management tool in any business. But how do you prepare a cash flow forecast?
Forecasts can be as simple or as complicated as business needs dictate. For the purposes of this article, I’m going to keep the forecast fairly simple.
A basic cash flow forecast will take a few hours to create, and then another hour or so each week to update. This of course depends on your proficiency with Excel, or your willingness to part with your precious cash to purchase one of the many cash flow forecasting tools available – personally I prefer Excel as it enables full control over content and presentation so I can tailor the forecast to the particular needs of my business.
There are 5 steps in creating a cash flow forecast:
Step 1 Prepare a list of assumptions
Forecasts are driven by assumptions and therefore for the forecast to be useful the underlying assumptions must be appropriate to the business.
Assumptions can be based on past performance, industry publications, correspondence from customers and suppliers, etc. and generally include:
· Timing and quantum of price increases – both yours and your suppliers’
· Sales growth estimates
· Impact of seasonality
· Provision for general cost increases (CPI)
· Provision for internal salary and wage increases
Listing the assumptions within the forecast adds credibility serves as a reminder when assessing actual performance against forecast.
Step 2 Prepare anticipated sales income
Sales can be difficult to predict, and often the best place to start is to look at sales in previous years to identify trends. You can then identify internal (e.g. price increases) and external (e.g. economic) factors likely to impact the current period, and make necessary adjustments.
When you have determined realistic sales for the period, they need to be broken down into sales receipts (i.e. When is the cash expected to be collected from debtors?). There is often a pattern to debtor remittance (e.g. 60% within terms, 25% one month outside terms with the remainder coming in shortly thereafter). Note: this pattern should form one of the forecast’s underlying assumptions.
Step 3 Prepare a list of ‘other’ estimated cash inflows
To ensure your cash flow forecast is complete, compile a list of all other anticipated cash inflows, for example:
- GST rebates and tax refunds
- Insurance proceeds
- Additional equity contributions or loan proceeds
- Government grants receipts
- Cash from asset divestment
- Royalties or franchise/license fees
Step 4 Prepare a list of estimated expenses
These should include direct and indirect expenses. The key is identifying all the expenses required to operate the business and anticipating the timing of each payment. Cash outflows relating to financing and investing activites should be included, for example:
- Payments to suppliers
- Wages and salaries of all staff
- Purchase of new assets
- Loan repayments
- Director drawings
Bank statements are an easy way of identifying direct debit arrangements.
Step 4 Putting the information together
Simply put, a cash flow forecast is a rolling calculation based an opening cash position, adding cash inflows and deducting cash outflows, to arrive at a closing cash position. Click on the link below to view a sample template:
Finally, it’s always a good idea to run some ‘what-if’ scenarios on the completed forecast to determine how much capacity your business has to with-stand unforeseen events.

You mentioned 13 weeks cash flow forcast for a few times in your different post. Do you have a template of it?
If someone’s never used excel, how does this compare to Quickbooks software?
Hi Maria, thank you for your comment. When it comes to cash flow forecasting I prefer Excel to Quickbooks – every business has its own peculiarities and the flexibility Excel offers enables me to tailor the forecast to the particular business I’m working with. Excel is an extremely powerful business tool, in my experience many SME owners and managers under-estimate its functionality – I highly recommend giving it a go!
Wow! Thank you! I always wanted to write in my site something like that. Can I take part of your
post to my blog?
Absolutely! I would appreciate if you kept the wording as is and include a link back to my blog.
Cheers,
Elizabeth
Hi Ma’am Elizabeth,
I took the liberty in downloading your cash flow template, I was a big help in our assignment in my college class. Even the professor was impressed with my assignment..Thanks for the big help.
Hi Catherine, thank you for your comment you are very welcome!
Hey Elizabeth,
I was just wondering how often you revisit your cash flow forecasts to adjust them? Or is that something you don’t really bother with once they’re made?
Hi Jan,
For cash flow forecasts to be a meaningful tool in the decision making process they need to be updated and flex-tested regularly. In my experience a rolling 13 week cash flow forecast provides management with sufficient visibility to plan for working capital requirements – in particular anticipated periods of cash shortage.
The 13 week cash flow forecast should compliment the annual cash flow forecast, with the annual forecast being updated from time to time – maybe as part of a monthly or quarterly management report.
