Business Forecast


I met with a friend recently who shares my interest in launching and funding startups.  He told me an interesting story that resonated at many levels.  It went something like this:

Back in the 1980s when he was seeking his first financing, my friend had lunch with a senior partner at one of Silicon Valley’s top venture firms.   During lunch, the VC paused, looked my friend, and said,

“There are three types of companies we end up investing in whether we like it or not:

  • The Dead On Arrival – those who never make it beyond their initial funding before going belly-up
  • The Living Dead –those who somehow manage to avoid going belly-up, needing more and more investment capital just to stay on life-support, and
  • The Home Runs those who so far exceed our hopes and expectations it makes all of the others worth the trouble.”

The VC went on watching my friend wonder which category his company might fit into.

“Most of our portfolio companies end up in the first two categories—‘The Dead and the Un-Dead’…Nine-out-of-Ten I’d say…and these are the ones we didn’t reject off-hand!  But once in a great while we’re lucky enough to invest in a “Home Run”—a really great startup that helps us to absorb all of the losses from the others, and make a handsome return for our partners and for us.  That’s why I’m buying you lunch!” 

The VC paused, then asked my friend, “But do you know what one thing all of these companies have in common?”  My friend put his fork down and shrugged his shoulders, waiting for the VC’s answer.

The VC smiled and took a deep breath.

“None of these entrepreneurs had the faintest idea about how to realistically forecast their company’s financial performance!”

My friend learned from that lunch what I have also learned in my years of launching and helping fund startups--that few if any good investors believe the forecasts presented to them, due mainly to the fact that few entrepreneurs understand the importance of realistic forecasting. 

In the pages ahead I will share with you some of the major ways poor forecasting can sabotage your business plan and your financing.  I will also share some of the lessons I have learned about how to avoid these pit-falls and secure the financing you need to launch and grow your enterprise.

Forecasting:  The Forgotten Part of the Plan

I frequently read detailed multi-page start up  business plans with pages of description and financial detail of every line including details such as paper supplies and print ink. However, one of the most important drivers of the plan, the forecast, is often comprised frequently of a few paragraphs or less. In point of fact, forecasting is often relegated to a minor role in the business plan and often key elements are overlooked.  Examples include:

  • One client forecasted a one percent sales growth per week based on what a venture capital firm told her was required for financing
  • Clients frequently ignore competition and pricing details, including  the role of online distribution such Amazon and Ebay in developing their forecasts   
  • Market forecasts frequently ignore key market segments and niches. For example,  premium customers and products frequently represent less than 10-20% of a plan’s total market.  Mass merchants such as Walmart and Target can represent  30-60 % of a retail product market while boutiques and specialty retailers may be inconsequential.

The process of giving the business plan forecast its deserved place is not easy.  This is so for many reasons, including:

  • Forecasting is difficult (if not impossible) to do accurately.  Key assumptions required for good forecasting are not always evident, and key metrics are not always clear.  In the absence of a clear path by which a forecast might be developed, many entrepreneurs gloss over it.  For example, the most reliable and recommend tool for forecasting is a company’s own historical track record, which is simply not available for startups.
  • Forecasting is easy to over-simplify.  The proverbial “Hockey Stick” graph of revenue growth is a classic example of this. The fast growth rate looks impressive on the surface, but the entrepreneur's lack of restraint leaves the opposite impression with investors. The steeper the pitch of the hockey stick revenue line, the more investors will question the entrepreneur's business judgment. I read a plan a short time ago that had 20 beautiful pages of financials and charts based and about one paragraph on the assumptions behind the forecast coupled with—you guessed!  The Hockey Stick.
  • Forecasting is often not based in reality.  Demand, competition, market size, pricing marketing expense etc. must all be considered, quantified and explained in developing a solid and credible forecast.  For example, the current mantra seems to be that social media networks will generate whatever “buzz” and sales a company needs. However this argument seldom has a solid explanation regarding how, what, when and where such meteoric growth in customer awareness and purchasing will occur.

Avoiding the Pitfalls of Poor Forecasting

So how does one develop a good forecast with little market data, no history and a brand new product or service?  My approach—developed over many years of experience--is to utilize a variety of time-tested tools and then to develop a most likely scenario based on the best information available.

Before starting this process you must learn to avoid what is generally called confirmation bias.  Here’s where things can easily go wrong in most forecasts and market testing.  It’s Human Nature:  We usually test to prove our hunches right. We start our forecasting with a favored option and try to build a case around it.  We may deny this tendency, but it is all too common among hopeful entrepreneurs. The result is that the less-favored alternatives usually get short shrift—and these are often the more probable scenarios. The more that there is at stake in the test, the more susceptible we are to confirmation bias.

Once you have addressed the pitfalls of your confirmation bias, it’s time to take an honest look at your market or markets.  Today it is easy to generate market data—it’s a keystroke away on the internet.  There is abundant market and census information on total markets such as how many pizza parlors, on line apparel retailers or fitness centers exist in the country and sometimes even in a state or local area. However such information is not always current or accurate, and even the best of market data can be too broad or generalized for your plan, which may target a narrow segment or area of a market or location.

Some suggestions for mediating this dilemma are:

  • Define your market in terms of products, demographics, region, prices, distribution, growth, etc.
  • Use surrogates like sales per square foot, other websites or other services to develop parameters on your business. For example here is a simple chart for one person providing personal services by hours and rates

Other key elements of realistic market assessments pertaining to your forecasts include:

  • Why are you different?
  • What is your history or comparisons with competitors?
  • What is the market capacity and trending?
  • How will marketing generate your sales?
  • How will competition  react to your initiatives?
  • Who might enter the market once you appear on the scene?

A final word about Market Assumptions

The first stage in creating the sales forecast is to estimate Market Demand. Market Demand for a product is the total volume that would be bought by a defined customer group, in a defined geographical area, in a defined time period, in a given marketing environment.

Once you have estimated the total market demand, you can estimate your company’s share of that demand:

                        Company Demand = Market Demand X Company’s Market Share

The final element in forecasting market demand is to look at future demand for your products or services.  Future demand is based on the growth of sales in the industry and changes in the market share.

Sales Forecasting

Accurately predicting future sales is perhaps the most difficult aspect of the forecasting process.  This is based on what management expects to happen to the company’s market share, coupled with the estimated demand for the company’s products or services at the proposed price points.

Specific sales forecasts can be based on a integrating a variety of information and efforts:

  • Actual customer buying results and attitudes. For example how do price changes, or promotions affect sales on a long and term basis?
  • Marketing and brand efforts and long term impact
  • Competitive and distribution changes. For example retail store sales are growing about 1 % a year and internet sales 15-20 %
  • What customers have done in the past in the market
  • Time series trends for the market and company
  • Seasonal or cyclical factors. Sales are affected by swings in general economic activity (e.g. increases in the disposable income of consumers may lead to increase in sales for products in a particular industry). Seasonal and cyclical factors occur in a regular pattern;
  • Erratic events; these include strikes, fashion fads, war scares and other disturbances to the market which need to be isolated from past sales data in order to be able to identify the more normal pattern of sales


While forecasting is never a precise science, there are numerous causes and efforts that can be used to mitigate the pitfalls and optimize the probability that your forecasting will support—not erode—your chances for successful financing:

  • Recognize that the playing field is never level. For example, Owners of competing businesses may have more contacts in your industry, they may have access to more capital (deeper pockets), and they may even have a stronger support network of family, friends and investors
  • Understand the various factors in your business and market to produce better quality, more accurate and credible forecasts that support your plans to succeed and grow
  • Have a clear marketing strategy. You never know where, when, or how a new prospect is going to hear of your business. If you have a mix of messages out there, the prospects will have an unclear expectation of what your business has to offer. Your company must present a consistent, clear message on all fronts
  • Understand pricing and pricing dynamics . Lower prices don’t necessarily mean more customers. Many customers are willing to buy more expensive items because of the greater quality or the added convenience. However many presumed benefits are neither real or relevant, and some intangible benefits are not easily communicated 
  • Clarify the purpose of your company beyond just making money.  This will set the stage for attracting like-minded investors, staff, and strategic partners
  • Set specific, measurable, accountable, realistic and time specific goals to ensure continual progress.
  • Even if you have the latest, greatest, never-been-done-before approach to something, don’t assume that you have no competition. Competition is more than just the direct, obvious competitors. Competition is also all the available alternatives
  • If you go in expecting to be rich overnight, you may become discouraged early on and give up your dream prematurely. Success takes time, perseverance, and a little bit of luck. Give your business time to grow.
