A cash flow forecast is an estimation of the money you expect your business to bring in and pay out over a period of time. Quality accounting software can help you to create a cash flow forecast with relative ease, but it's well worth understanding what a cash flow forecast actually encompasses.It should reflect all of your likely revenue sources (like sales or other payments from customers) and compare these against your likely business expenses (like supplier payments, premises rental and tax payments).Despite the fact that your actual annual incomings and outgoings will likely deviate from the plan throughout the year (that’s where the ‘forecast’ part comes into play) – your plan is still important. It will never stay completely accurate but it gives you an important general overview of what to expect.

For example, what kind of social media marketing will you use? What kind of project management systems will you use to keep track of all your ideas?Helps you plan for seasonality – let’s say you have a huge increase in sales expected in October. Now you can plan to spend a little more on marketing in that month, for example.

A cash flow forecast is sometimes also known as a ‘cost volume profit’ or ‘break even’ analysis.You break even when total incoming costs = total outgoing costs. When should I create a cash flow forecast?Your cash forecast plan should be created as part of your business plan, right at the beginning when you start your business. It’s okay if you haven’t yet, but as our expert Benedict states:“Don’t put off your cash flow forecast. You might have a business model that makes a profit in the very first year, and you might meet every target you set. But if the income is at the end of the year and the spending is at the start, you might run out of cash in the middle, and watch the business fail just because you didn’t realise the cash would run out.” Who is my cash flow forecast for?You might be creating a cash flow forecast for yourself, your bank or potential investors and shareholders who may really want to drill down into the nitty-gritty of your business.Here, Benedict points out:“Who your cash flow forecast is for should affect your approach:If it’s for yourself, then be PESSIMISTIC in all your estimates. It’s always a good idea to have a bit of a buffer in case things go wrong (and something almost always goes wrong).If it’s for a bank or other outsider, then be OPTIMISTIC in all your estimates. You want to present your business in a flattering light, after all.However, it’s really important to not go crazy either way – your estimates have to be realistic, or the whole forecast will be a waste of time.” Creating a cash flow forecast: getting startedCash forecasts typically contain:1. Incoming costs such as sales revenue, customer account fees, or funding.2. Outgoing costs such as staff wages, operating expenses, and any other associated labour costs. This can cover everything from advertising costs to office supplies. What software should you use for a cash flow forecast? What you will need:A basic spreadsheet program, such asMicrosoft Excel or Google Sheetswill work fine when you’re starting out.Even a pen-to-paper forecast could work!What you will not need:Any special software(although, accounting softwarecan make things easier.) While you don’t need any special software to get started with your cash flow forecast, but if you want to make things a little easier for yourself, accounting software such as Freshbooks or QuickBooks often have cashflow forecast templates you can use.Quickbooks offers a 24 month cash flow forecast at no extra charge and you can track projects, jobs or locations to see where you’re making the most money, and Freshbooks allows you to pull data right from their software.Check out our list of Startups.co.uk approved accounting software below: Step 1: Create a spreadsheetThis part is simple, and can be done using Microsoft Excel, Google Sheets or OpenOffice:First, you’ll need to decide on the length of time you want your cash flow forecast to cover. This can be week to week, month to month, or yearly (but we recommend perhaps only 1-2 years to keep things accurate because you never know how much will change – and it will! – over such a long period of time.)Next, you will set yourself up with a simple spreadsheet with a column for the time period you’ve decided, and a row for profits and expenses which will set you up for success throughout the next 12 months, or however long you choose.You’ll then want to add a final row at the bottom across all of them for your monthly totals (preferably in a different, eye-catching colour) where you’ll record your profit minus expenses. (More on this below) Step 2: List all of your incomeYour sources of income may include:(Emergency) savingsExpected salesAny startup grants or loansAny investments you’ve receivedDividends and interestetc…When you add all of these sources together, you will have the figures of your total income. Step 3: List all of your expensesYour expenses may include:Wages and other associated labour costsEquipmentTrainingDebtsRent on your office space or commercial buildingElectricity bills among othersVAT liability (if applicable)etc… Step 4: Work out your net incomeGross profit minus expenses = net incomeFor each week or month column, take away your estimated expenses from your estimated income.That will give you either a positive cash flow figure (when you have more cash coming in than you’re spending) or a negative cash flow figure (you’re spending more than you have coming in).You can then keep your running total to get a picture of your cash flow forecast over time. With all these figures in one place, you can easily work out the total amount your business makes per month, and the total amount your business spends each month.Another huge added bonus of calculating all of this is that these figures will all help to make things so much clearer when tax season rolls around. You’ll already be familiar with most of the terms you need to know for your returns, and the figures to go with them. Cashflow jargon busterOverheads – The money you spend on your business that doesn’t directly relate to your sales. For example, if you run a pottery business, the clay you buy to produce your pots would be part of the costs of sale, but the electricity that powers your studio would be an overhead. Other common overheads include insurance, rent, and advertising – in other words, the running costs for your business. One important point here: if you run a services business, then all your costs are overheads.Cash inflow – This one is nice and easy – it’s the money that comes into your business. This will mainly be from sales, but could also include things like tax rebates, business loans, or other outside investment.Cash outflow – This one is also pretty straightforward – it’s the money that goes out of your business. Most of this money will be either overheads (see above) or costs of sales (things you buy that are directly related to the things you sell).Gross profit – Your gross profit is the amount of money that you make from sales, minus the costs of sales. In very simple terms, it’s the money you make from selling the things you make (or buy), minus the money you spend making (or buying) the things you sell. If, for example, a business made and sold wooden stools, the gross profit would be the total amount the stools sold for, minus the cost of the wood used to make them.Net cash inflow – A fancy way of saying that your business is earning more than it’s spending – in other words, it’s making money.Net cash outflow – A fancy way of saying that your business is spending more than it’s earning – in other words, it’s losing money. When should you update your cash flow forecast?Once you’ve put together your cash flow forecast, the obvious temptation is to file it away and get on with running your business.However, to improve your cash flow forecast, the best practice is to try and update it whenever there is a significant change in either your profit or loss.Benedict has a few key ideas for different kinds of forecasts here:“If you're feeling strong when you finish your forecast, make two new copies of it, then change the numbers in one to be the best possible future and one to be the worst possible future.Shade the good one green and the bad one red. Seriously, take it from an accountant: looking at lots of similar spreadsheets will blur your vision, and bore you into making silly mistakes. Treat yourself like an idiot who needs everything clean, simple, and colourful.Doing this will give you a much better idea of how your business would be able to cope with problems such as losing a key customer, or a sudden increase in the cost of your supplies.” ConclusionGetting your head around creating a cash flow forecast makes it easier to run your business, as you’ll have a reasonably accurate idea of how your cash flow looks in the months ahead.If you really don’t have the time to tackle it however, then you can think about investing in some quality accounting software – this is optional of course, and we hope this guide has given you the knowledge and tools to be able to try creating one for yourself – but many accounting software packages have forecasting tools that save you from having to do all that number-crunching, and the good news is that most these days are HMRC-recognised and compliant with the new MTD legislation that came into effect in the UK on April 1 2022.However you decide to create, manage, implement and optimise your cash flow forecast, may it always be sunny and profitable! Frequently Asked Questions What should a cash flow forecast include? A cash flow forecast should include an overview of your projected gross profit, expenses, and the total net income (which is your gross profit minus expenses). What are the two main types of cash flow forecasts? You can create a direct or indirect cash flow forecast. Direct uses your existing balance sheets and harder figures to calculate a more realistic, immediate forecast, whereas indirect takes into account estimated profit that hasn’t materialised yet and would be the outcome of additional efforts (i.e. more marketing, having a successful launch or fulfilling a business strategy as intended). Is cash flow the same as profit? Cash flow indicates both profit and loss to give a more accurate overview of everything that is happening within the business as a whole.
