7 Proven Sales Forecasting Methods To Predict Your Revenue (2024)

How many leads do we need in this quarter to hit our revenue targets?

How much will the revenue target be in 2022?

Do we need to increase our sales team numbers to hit our sales goals?

How much revenue will this new product bring in?

Sales Managers, VP of Sales, and sometimes even CEOs ponder over these and many other similar questions. And why? Because sales is the lifeline of any business and having a general idea of what to expect in the future will help in making informed decisions.

The answer to these questions lies in Sales Forecasting.

By sales forecasting, you get a clear picture of how much new revenue your company will generate in a given period of time. It gives you the right insights and helps you take the necessary steps towards continuous growth.

However, sales forecasting isn't a walk in the park. Because predicting your sales over a said period of time can be tough due to a range of different reasons. And despite how accurate you think your sales forecasts are, you will never be 100% right, because if you are, you might as well be a time-traveller - in which case, can you tell me when Bitcoin rises from the ashes?

Here, we’ll take you through effective forecast methods, step-by-step. But, before we jump into that, let’s first look at some of the basics - what sales forecasting means, its importance, and the factors influencing it.

What does Sales Forecasting mean?

Sales Forecasting is the process of estimating the number of sales for your business over a future period of time. This forecast period can be monthly, quarterly, half-yearly, or yearly.

Sales Forecasting can be done for an individual sales rep or a sales team or a particular department in the company. It helps managers/executives keep track of their performance through ametrics dashboard and take corrective action when needed.

Usually, sales forecasts are based on past sales data, industry-wide comparisons, and current economic trends. It is easier to come up with a sales forecast if you have a good amount of data in hand. However, newly established companies that don't have a substantial amount of historical data are forced to depend on market research and competitive intelligence to base their forecasts on.

Importance of Sales Forecasting

The goal of forecasting is not to just predicting the future but to tell you what you need to know to take meaningful action in the present.

- Paul Saffo

Sales forecasting is not just about predicting your sales numbers, it’s about having the necessary information that enables you to make the right decisions today that will help you in the future - that’s why businesses should forecast.

  • Spots Potential Issues: Midway through the quarter, you notice that your sales team is not hitting their targets. You dig deep and find out that there aren’t enough leads being generated for the sales team to convert. Shift your focus on to the marketing department and let them know that they’ll have to ramp up their operations and improve their lead generation strategy to bring in more leads. In short, sales forecasting allows you to spot potential issues and gives you time to avoid or alleviate them.
  • Hiring and Resource Management: Sales forecasts also help you make hiring and resource/inventory management decisions. Assume that your forecast predicts an uptick in demand. To meet that demand, you’ll need to allocate a budget and divert your effort towards hiring and getting resources. And on the other hand, if it is predicted that there will be a decline in sales, it is time to put a pause on hiring and resource plans and shift your focus into bringing in more business.
  • Drives Performance: Going by the popular saying, What gets measured gets done, having a forecast report in front of you lets you know what your goals are and keeps you focused. It gives you the necessary information to make decisions that will improve your results.

Factors Influencing Sales Forecasting

  • Economy Conditions: It goes without saying that the condition of the economy has an impact on every business and market. If there is a depression in the economy, people/businesses will lose money and they’ll be more reluctant to purchase, and when the economy is strong, people are most likely to invest and buy.
  • Policy Changes: Changes in policies or the introduction of new laws/regulations can either help or hurt your business. So, when predicting your sales for the next period, it is vital that you take these into account.
  • Industry Changes: Every industry has similar products made by different organizations. Factors such as new tech improvements, design, competitors running promotional campaigns, or new businesses entering the ring can change and affect the market share of the industry – which in turn will factor into your sales forecasts.
  • Product Changes: Changes in your product can heavily influence your sales forecast. These changes may be rolling out a new feature due to high demand or removing a useless feature or removing bugs. Salespeople can leverage these product changes to shorten their sales cycle and close more deals.

Sales Forecasting Methods

Length of Sales Cycle Forecasting

This forecasting method uses data on how long a lead typically takes to convert into a paying customer. For example, if an average sales cycle lasts four months and your sales rep has been working on a prospect for two months, there is a 50% chance that your rep will close the deal.

Forecasting using the length of the sales cycle is a great technique because it’s completely objective, and your forecast isn’t dependent on a subjective factor like, your reps’ gut told them that they’ll close or they’re feeling good about this prospect.

Another advantage of this method is that it can be applied to a slew of sales cycles, depending on the source. For example, a referral client might take two weeks, while a cold email outreach client might take three months. All these leads can be separated into various buckets according to their source to give you a more accurate picture – forecast.

This method is most valuable for companies that religiously track how and when prospects enter the sales pipeline. So it is essential that your sales and marketing teams are strongly aligned with each other.

Pros:

  • It’s completely objective.
  • It can be applied to various lead sources to give you a more accurate forecast.

Cons:

  • The sales cycle can vary according to who you’re selling to. It will be shorter for SMBs and longer for enterprises.
  • Your sales team should relentlessly track data. Even a small error can throw your predictions way off.

Lead-driven Forecasting

Lead-driven forecasting involves analysing each lead source and assigning a value based on what similar leads have done in the past and creating a forecast based on that source value. By assigning a value to each of your lead sources, you’ll be able to get a better sense of the probability of each lead that can turn into revenue-generating clients.

For this method, you’ll need to have data on these metrics:

  • Leads per month for the previous time period
  • Lead to customer conversion rate by source
  • Average sales price by source

This data-driven forecasting is susceptible to changes though. For example, if your marketing team changes its lead generation strategy to align with the latest trends, this can change the number of leads from different sources, which will change your lead to customer conversion rates. These varying end-results can be minimized by being updated on the latest changes and by taking them into account when forecasting.

Pros:

  • The lead value for each source gives you a more accurate sales forecast.

Cons:

  • Highly susceptible to variance due to multiple factors being involved.

Opportunity Stage Forecasting

In this approach, you take a look at where the prospect is in your pipeline and calculate the chances of the deal closing. Companies can break down their pipeline into various stages; like prospecting, qualified, demo, quote, closing, etc., and track everything using a sales pipeline software. Generally, the further the prospect is down the pipeline, the better are the chances of closing the deal.

7 Proven Sales Forecasting Methods To Predict Your Revenue (1)

To implement this technique, you’ll need to analyse and understand your past performance so that you can get a good estimate on the rates of success for each stage of the pipeline. For example, rep X is working on a $5000 deal and has reached the stage where the prospect is done with his/her free trial of the product, and the probability of them becoming customers is 60% after the trial stage, your forecasted amount will be $3000.

However, despite being a data-driven prediction, it isn’t entirely accurate. Opportunity Stage Forecasting doesn’t take into account the individual characteristics of each deal like the age of the lead. For example, a prospect might be at the trial stage for around two months and they’d have the same success rate as a hot lead who reached the trial stage in a few weeks.To counter this problem, the VP of Sales at FullContact, Mike Brouwer developed a new methodology to forecast sales for his team.

Pros:

  • The calculations are simple enough.
  • This technique is highly objective.

Cons:

  • It doesn’t take into account the characteristics of a deal like age, deal size, and so on.
  • Inaccurate data can give you inaccurate sales forecasts.

Intuitive Forecasting

Who better to ask whether the sale will happen or not than your own rep guy?

The Intuitive Forecasting method is based on the trust you have on your sales reps. You start by asking them how confident they are that their sale will close, and when. It factors in the opinion of the sales reps who are the ones closest to the prospects – they are most likely to know how things are going.

You can certainly see the downside in this method. It’s entirely subjective. The reps are naturally inclined to be optimistic and will likely offer generous estimates. And there is no way to verify this assessment other than going through all the interactions between your sales rep and the client, which is just extra work.

Pros:

  • It’s a great way for newly founded companies who don’t have historic sales data to base their sales forecasts on.

Cons:

  • It’s highly subjective. Reps tend to be more optimistic about their chances with their opinions.

Test-Market Analysis Forecasting

With this method, you can roll out your new product/service to a certain group of people based on their market segregation. For instance, you can release the product to a limited, geographical area and see how it sells. This result is then studied and can be used to make an accurate forecast for the full release.

The Test-Market Analysis forecasting is useful for large companies who are rolling out a new product and would like to understand the market response, or a startup doing a soft launch to increase their brand awareness.

However, with this method, you should remember that not all markets are the same – what happens in one market might not happen elsewhere.

Pros:

  • You get to learn the market response first hand and fix any issues before the final launch.
  • Startups can give exclusive early access to their product. This exclusivity increases brand awareness and brings in an air of mystery making your product more desirable.

Cons:

  • Releasing a beta version or doing a soft launch can be quite costly.
  • Not all markets are the same.

Historical Forecasting

As the name suggests, with Historical Forecasting you take the previous sales data for a certain time frame and assume that your sales will be equal to that or greater.

For example, if your Monthly Recurring Revenue (MRR) in May was $50,000, using Historical Forecasting you’d assume that the MRR for June would be at least $50,000. You can add your average year-on-year growth rate, say 10%, and the estimate for June would be $50,500.

There are issues with this method though. It doesn’t consider the fact that the market is always changing. For instance, during June if your direct competitors ran a promotional campaign for their product, you will most likely see a decline in sales and you could end up selling less than $50,000.

With that in mind, Historical Forecasting is a quick and easy way to forecast, it can be used as a benchmark rather than the foundation for your sales prediction.

Pros:

  • It’s quick and easy to do.
  • If your market isn’t susceptible to many changes, Historical Forecasting can prove to be highly accurate.

Cons:

  • Doesn’t take into account the seasonality of the market.
  • The sales pipeline isn’t taken into consideration.

Multivariable Analysis Forecasting

Incorporating various factors from other forecasting techniques like sales cycle length, individual rep performance, and opportunity stage probability, Multivariable Analysis is the most sophisticated and accurate forecasting method.

Consider this simplified example. Two sales reps are working the same account. Rep A is working on an $8000 deal and has just finished the demo; according to the opportunity stage forecasting, the win rate for a completed demo stage is 60%, hence the sales forecast for this deal is $4800.

Rep B is working on a smaller deal of $3000 and is earlier in the sales process, but Rep B’s win rate is around 80% making the forecast $2400. Now the total sales forecast for this account is,

$4800 + $2400 = $7200

Unlike this example, forecasts based on Multivariable Analysis are highly complex, it requires advanced analytics solutions, making it impractical for small businesses or start-ups. You’ll also need clean data – sales reps should track the deal progresses and activities or else your results will be inaccurate no matter what software you use.

Pros:

  • A highly data-driven method that produces accurate results.
  • Despite the math being complex here, the sales rep need not learn them as the analytical tools themselves will calculate and produce the forecast results.

Cons:

  • Advanced analytical tools are needed and they can be a bit heavy on the company’s wallet.
  • Presence of dirty data can give you inaccurate sales forecasts.

How To Improve Sales Forecasting Accuracy?

More than 50% of sales leaders and sellers are not confident about their sales forecasting accuracy, says a study by Gartner. This is because most of them rely on intuition to forecast their future revenue.

Here’s how to improve your sales forecasting accuracy :

1. Choose the Best Forecasting Method

Before you double down on any forecasting method, consider these questions to identify the best forecasting method for you:

  • How long have you been in business?
  • How big is your sales team?
  • What are your business plans?
  • How often do you track sales data?

Not much historical data will be available if the business is relatively new. In that case, go for the intuitive sales forecasting method, where you ask your salespeople the probability of closing deals.

If you are an established business planning to launch a new product, the test-market analysis forecasting method is the one for you. Release the product to a certain market segment to study and forecast for the whole market.

Going ahead with the historical data won’t hurt your business much if the market and economic scenario are steady. When most variables remain constant, aiming for a 10% increase in revenue from last year is realistic and achievable.

Length of sales cycle method, multivariable analysis, and lead-driven analysis are perfect if you track data often, as they require accurate and clean data.

2. Qualify Your Pipeline Continuously

A sales opportunity is never a sale unless you close it. Most salespeople struggle to accept this hard truth and find the comfort of a fat pipeline with opportunities more appealing. Rectifying this rookie mistake by continuously qualifying the pipeline is one of the effective ways to forecast sales accurately, says Julie Thomas, CEO of ValueSelling.

Here’s a framework she offers in her recent article on Forbes to qualify the pipeline. Ask these questions to weed out those opportunities that are least likely to close:

Is my product the best solution for the prospects?

Why should you ask this?

If their goals don’t align with the solution you’re offering, the chances of them converting are very less.

How important is solving the problem for the prospects?

Why should you ask this?

If solving the problem isn’t an immediate priority for them, your product is dispensable.

Do they hold decision-making powers?

Why should you ask this?

If you don’t target the right decision makers, you’ll waste time giving product walkthroughs to the wrong people only to see them pull out at the last minute.

When are they likely to buy?

Why should you ask this?

Focusing on prospects with an immediate requirement for your product ensures quicker sales and shorter sales cycles. It saves you from last-minute surprises like the prospect asking you to get back the next quarter when you are steps away from closing the deal.

3. Invest in Sales Forecasting Tools

Sales forecasting tools are your secret weapons for quicker and more accurate sales forecasts. When you rely on them to do the heavy lifting, you rule out the chances of forecasting based on intuition.

Ease of use, the scope of collaboration, ease of integration with a CRM, and forecasting capabilities are some of the most important factors you should consider before choosing the best sales forecasting tool for your business. Gong.io, Pipedrive, and Map My Customers are some of the efficient sales forecasting software available today.

In Short

Like a stock trader adjusting the portfolio based on economic forecast or,
a campaign manager plotting the election campaign route for the candidate based on a political forecast,

a sales manager or a VP of Sales should make informed decisions and plan their sales strategy based on the sales forecasting reports.

However for your sales forecasts to be accurate, it is important to be data-driven. Data-driven sales forecasting can give you greater control over your operations, help you avoid pitfalls effectively, and can even inspire your team to beat the forecasted targets.

So, in this modern age, a data-driven sales forecasting is must have to drive your business successfully.

Frequently Asked Questions About Sales Forecasting [FAQs]

What is sales forecasting?

Sales forecasting is an exercise to estimate the future expected sales revenue for a business over a specific period of time – monthly, quarterly, half-yearly, or yearly. This helps managers/executives keep track of the sales team’s performance and take corrective action if required.

Why should you do it?

Sales forecasting helps a business in identifying potential problems in the sales team for early resolution, improving the performance of the sales team by presenting clearly defined goals, and making informed decisions regarding hiring and resource management.
So, it is important to know beforehand.

How to forecast sales using historical data?

To forecast sales using historical data, take the sales data from a certain time frame in the past and assume that your sales will be equal to that or greater. For example, if your Monthly Recurring Revenue (MRR) in May was $50,000, using Historical Forecasting, you’d assume that the MRR for June would be at least $50,000. You can add your average year-on-year growth rate, say 10%, and the estimate for June would be $50,500. Though a quick and easy way to forecast, this method isn’t the most accurate as it doesn’t consider the influence of seasonality on sales.

How to forecast sales for a new product or service?

You can use the test-market analysis method to forecast sales for a new product or service. In this method, you launch your new product/service to a certain group of people based on their market segregation and study their results to make an accurate forecast for the full release. Launching beta versions create a buzz around your product and let you rectify product shortcomings before the launch.

Why is sales forecasting accuracy important?

An accurate sales forecast does much more than predict your future sales numbers. It gives you an idea of how and where to spend money and resources. For instance, if the forecast predicts an uptick in demand, you’ll need to allocate a budget and divert your effort towards hiring and getting resources. It also allows you to spot potential issues in your prospecting process and gives you time to strategize to still meet your sales target.
