What Is a Sales Forecast and Why It Matters
A sales forecast is your estimate of how many products or services you expect to sell over a specific period — weekly, monthly, quarterly, or yearly. It shows how your business will make money and how fast it can grow.
When included in your business plan, your sales forecast tells potential funders, investors, or partners that you understand your market and can plan ahead. It also helps you prepare for things like cash flow, expenses, staffing, and inventory.
No matter how great your idea is, if you can’t explain how it will generate income, your business plan will appear weak. That’s why forecasting is critical.

What You Need Before You Start Forecasting
Before jumping into numbers, gather some information. Start with your pricing. You must know how much you’ll charge per unit. Next, know your product or service range. What are you offering? How many units or hours of service can you realistically sell in a day or week?
Also, research your competitors. What are they selling? At what price? How many customers do they serve weekly?
Understand your market size — how many potential customers are in your area or niche. For example, if you’re selling jollof rice to students near a polytechnic, how many students are there, and how many eat out daily?
These pieces of information help you build a realistic sales forecast.

Step-by-Step Guide to Forecasting Sales
Start by listing all your products or services and their prices. Estimate how many units you expect to sell each day, week, or month. Multiply units by price to get your sales value. Then sum up everything.
Example: A smoothie business sells three types of drinks at ₦700 each. If you expect to sell 15 bottles daily, that’s ₦10,500 per day. For 6 days a week, you’ll make ₦63,000. Multiply by 4 weeks and you have ₦252,000 monthly.
Use separate rows for each product. Always forecast per product, not as a lump sum. Break it down clearly so anyone reading your plan understands where the money will come from.

Forecasting Sales for New Businesses in Nigeria
If you’re just starting, use assumptions based on research, test runs, or industry data. You may also use simple projections based on small-scale trials.
For example, if you plan to open a shawarma stand and did a 2-day test at a local park, where you sold 30 shawarmas daily at ₦1,500, that’s ₦45,000 per day. You can forecast 20–30 daily sales for your first few months.
Also look at your opening hours, number of staff, delivery capacity, and marketing strength. Don’t just guess numbers. Link your estimate to something tangible.
State your assumptions clearly in your business plan so the reader knows how you arrived at your figures.
-
Forecasting Sales for Existing Businesses
If you’re already running your business, you have an advantage. Use past sales data to build your forecast.
Check how many units you sold last month, how much income came in, and what trends you’ve noticed. Are sales higher during weekends or festive periods? Did any promotion increase your orders?
If you sold 1,000 units last month and expect a 10% increase due to a new location or more marketing, then forecast 1,100 units.
Use historical performance to build projections for the next 3–12 months. This approach gives you a stronger, more accurate plan.
-
Tools and Templates You Can Use
You don’t need expensive software. Use Excel, Google Sheets, or even your phone calculator.
Create simple tables showing:
- Product/service name
- Price per unit
- Estimated units per period (day, week, month)
- Total revenue
Make sure your table is neat and easy to read. You can also add a chart or graph if you’re presenting to investors or judges.
Some free templates online can be customized for your Nigerian business model. Keep it simple — your goal is clarity, not complexity.

How to Present Sales Forecast in Your Business Plan
Insert your sales forecast in the Financial Plan section of your business plan.
Start by writing a short paragraph explaining how you calculated your sales. Mention key assumptions like pricing, market size, sales volume, or growth plans.
Then include a table like this:
| Product |
Unit Price |
Monthly Sales (units) |
Revenue |
| Smoothie 50cl |
₦700 |
600 |
₦420,000 |
| Zobo 75cl |
₦500 |
400 |
₦200,000 |
| Parfait |
₦1000 |
250 |
₦250,000 |
| Total |
– |
– |
₦870,000 |
This format helps you tie sales directly to income. If you’re forecasting for 6 or 12 months, use a separate table or a summary.
Ensure your pricing and sales volume match what you stated earlier in your business plan.

Common Sales Forecasting Mistakes to Avoid
Don’t be overly optimistic. Avoid projecting unrealistic sales with no explanation. Don’t ignore your business limitations — such as production capacity, delivery options, or customer demand.
Avoid vague language like “We expect huge sales.” Always use numbers and show how you got them.
Don’t forget to include seasonality. For example, sales for cold drinks may drop during the rainy season. A salon might get more customers during festive periods.
Lastly, don’t hide your assumptions. The more transparent your forecast is, the more trust it builds.
Final Thoughts
Sales forecasting is not just for experts. Every entrepreneur needs to know how much they expect to sell, when, and why. This helps you set goals, manage expectations, and grow your business wisely.
When writing your business plan, take time to prepare a simple, realistic sales forecast. Use available data, make smart assumptions, and explain your process clearly. Whether you’re applying for ₦100,000 or ₦5 million, this section can be the reason your plan is accepted.
Start forecasting today. Even if you’re unsure, estimate something, track it, and improve over time. That’s how real entrepreneurs operate.
