The Complete Guide to Calculating Sales Forecast with Examples
Summarize this article for me pleaseWhat Is a Sales Forecast?
A sales forecast predicts future sales revenue for a specific period. This is based on factors like:
- Current sales data: To identify patterns and seasonality
- Market trends: To highlight shifts in consumer behavior and industry developments
- Historical performance: To reveal what has worked in the past, helping to establish reliable benchmarks
These elements give businesses substantial data to estimate sales for existing products, new customer acquisitions, and membership sign-ups. Plus, they can plan investments in new products and services and allocate resources effectively for growth.
There are two types of sales forecasts:
📌 Long-term forecasts: Extend beyond one year and rely on broader market analysis and historical data. They help plan for growth, set strategic sales goals, and allocate resources for new products and market expansion
📌 Short-term forecasts: Predict future sales for up to one year based on recent data and current market conditions. They guide decisions on inventory, staffing, and marketing

Sales leaders typically create a sales forecast to set targets for their reps. But it’s also a powerful tool for:
- Executives to plan budgets
- Marketing teams to set acquisition goals
- Entrepreneurs to attract investors
- Small-business owners to make key operational decisions
Here’s how to calculate a sales forecast and gain clarity on your financial and operational capacities for the future.
Sales forecast formula
While there isn’t a one-size-fits-all formula for sales forecasting, this simple formula can be your starting point:
🎯 Sales forecast = (average sale price) x (expected number of sales)
Let’s say you sell a software subscription that costs $500 per year and expect to sell 200 subscriptions in the upcoming quarter. To calculate the sales forecast for the quarter, you can use the formula:
Sales forecast = 500 x 200 = 100,000
This method is useful for predicting total revenue when you have a stable pricing model and can estimate the number of units sold.
You can also use the following formula:
🎯 Annual sales forecast = Total sales revenue so far + possible sales revenue for the rest of the year
This approach gives a more comprehensive view by considering confirmed and potential sales for the year.

Common methods for sales forecasting with examples
Businesses differ in size, industry, and market conditions, which is why no single sales forecasting method works for everyone.
Selecting the right method depends on factors such as:
- Business size and industry
- Available data and tools
- Complexity of the sales cycle
With that in mind, let’s explore some of the most common sales forecasting methods.
1. Historical sales data
Historical sales data forecasting uses past sales to predict future performance, assuming future sales follow similar trends. It’s effective for businesses with stable markets and products but can be less reliable for new or rapidly changing industries.
Here’s how it works:
- Analyze sales records over a specified period (e.g., past months or years)
- Identify trends, seasonality, and patterns
- Use this data for future sales projections, assuming market conditions remain consistent
For example, here’s the one-year historical sales data for a bookshop:
| Month | Sales Revenue ($) | Trend Identified |
| January | 10,000 | Post-holiday sales drop, steady recovery |
| February | 11,000 | Steady growth, new book releases |
| March | 12,500 | Seasonal spike (book fair promotions) |
| April | 11,200 | Return to steady growth |
| May | 13,000 | Increase due to summer reading trends |
| June | 15,000 | Peak sales month (graduation, summer sales) |
| July | 14,500 | Slight decline, mid-summer lull |
| August | 13,500 | Back-to-school increase |
| September | 12,800 | Consistent sales, school season start |
| October | 13,500 | Increase with fall releases |
| November | 16,000 | Pre-holiday rush (gift season begins) |
| December | 18,000 | Holiday sales spike (gift shopping) |
By analyzing this, the store identifies that:
- November and December see a sales spike, with December peaking due to gift shopping
- March and June are strong months, driven by book fairs and graduation
- February, May, and September show steady growth from book releases, summer trends, and back-to-school offers
- July sees a slight decline before sales pick up in August
Based on these insights, the bookshop can increase the inventory of popular gift items in December and tailor marketing strategies to capitalize on summer reading in May.
2. Pipeline-based forecasting
This sales forecasting process uses data from a company’s sales pipeline to predict future revenue. It focuses on active deals, their stage in the sales cycle, closing probability, and other key metrics like ‘deal value’ and ‘timeline.’
This approach provides real-time revenue insights and helps adjust forecasts as deals progress. Here’s how it typically works:
- Gather data on all deals in the pipeline, from leads to near-closure
- Assign a probability of closing to each deal based on its stage (e.g., lead, proposal, negotiation, close)
- Calculate each deal’s weighted value using its probability percentage
- Add the weighted values to create a revenue forecast
Let’s see a sales forecast example of a software company using the pipeline forecasting method:
| Client | Deal Value ($) | Sales Stage | Probability of Closing (%) | Weighted Value ($) |
| A | 35,000 | Initial meeting | 10% | 3,500 |
| B | 100,000 | Proposal sent | 40% | 40,000 |
| C | 50,000 | Product demo | 60% | 30,000 |
| D | 200,000 | Negotiation | 80% | 160,000 |
| E | 120,000 | Contract sent | 90% | 108,000 |
Adding up all the weighted values provides a total forecasted revenue of $341,500.
This forecast allows the sales team to allocate resources, refine strategies, and align sales capacity with opportunities to meet targets efficiently.
💡Pro Tip: Use a sales pipeline template to centralize deal data and automatically calculate weighted values. This lets you quickly identify high-priority deals and adjust strategies based on their likelihood of closing.
3. Market research
Market research provides direct insights into customer preferences, competition, and market demand. It’s ideal for businesses launching new products or entering new markets, navigating competitive or seasonal demand, and analyzing economic, social, or environmental impacts on sales.
For example, a company launching a new organic coffee line discovers:
- A growing trend toward organic and sustainable products, especially among health-conscious millennials
- Key competitors like Starbucks and local brands are already in the organic market but lack sustainable packaging
- Increased consumer spending on premium, ethically-sourced products
Based on these insights, here’s an estimate of potential sales and revenue, considering the price of each unit is $15:
| Customer Segment | Interest Level | Average Order Size | Projected Market Share | Estimated Monthly Sales (Units) | Estimated Monthly Revenue ($) |
| Health-conscious millennials | High | 2 units | 30% | 15,000 | $225,000 |
| Eco-conscious consumers | Medium-High | 1.5 units | 20% | 10,000 | $150,000 |
| Premium coffee enthusiasts | Medium | 2 units | 10% | 5,000 | $75,000 |
| General coffee drinkers | Low | 1 unit | 5% | 2,500 | $37,500 |
| Total | – | – | 65% | 32,500 | $487,500 |
This helps the company plan production, marketing strategies, and inventory management to meet expected demand in each market segment.
4. Expert opinion
This approach relies on sales experts’ industry knowledge, experience, and understanding of customer behavior to predict future sales.
It’s advantageous in new markets, for product launches, or when historical data is limited—especially in fast-paced industries like technology or fashion, where consumer demand can shift unpredictably.
Expert opinions often adjust forecasts based on deal size, close rates, and sales cycle length. Let’s see how:
| Factor | Influence on Expert Opinion | Quantifiable Example |
| Deal size | Experts assign higher forecast weight to larger deals with strong client commitment | A sales leader increases the forecast probability of a $500,000 deal from 40% to 70% because the client has completed four technical reviews and requested a formal proposal |
| Close rates | Close rates are adjusted based on recent trends, promotions, or changes in product appeal | For a product with a 25% historical close rate, a sales manager forecasts a 35% close rate due to positive feedback on a recent upgrade |
| Sales cycle length | Experts consider whether deals may close sooner or later than average cycle lengths based on customer behavior | For a deal in its fourth month of a six-month cycle, the expert predicts a faster close at 80% probability after the client requests faster deliveries and schedules internal decision-maker meetings |
Calculating sales forecasts is one thing, but managing and tracking them in real time can be challenging. That’s where you need comprehensive sales forecasting software that helps streamline the process.

Want to forecast like a pro? Here are two advanced techniques you can consider to take your sales predictions to the next level.
1. Time Series Forecasting
Time series analysis examines past sales data over a specific period of time to uncover hidden patterns, trends, and relationships. It employs advanced statistical methods like:
- Smoothing: Reduces fluctuations to reveal the underlying trend
- Decomposition: Breaks down trends into components like seasonality, cyclical patterns, and noise
- Forecasting models: Predicts future sales based on these patterns
By factoring in past performance and potential future fluctuations in demand, time series analysis allows businesses to create more accurate, data-driven forecasts—something basic methods can’t achieve.
2. Regression Analysis
This statistical method is used to understand the relationship between a dependent variable (like sales) and one or more independent variables (such as marketing spend, website traffic, or seasonality). It helps you see how changes in these independent factors influence the dependent variable.
For example, a business might use regression analysis to predict sales based on marketing spend. By analyzing past data, they might discover that for every 10% increase in marketing spend, sales increase by 5%.
This insight helps businesses plan future budgets and optimize their marketing efforts for better sales outcomes.
