When you’re starting or growing a franchise, having a clear picture of your future finances isn’t just helpful, it’s essential. Sales and profit forecasting gives you a roadmap for your business, helps secure funding and keeps you focused on hitting the right targets. Here’s how to approach it step by step.
Step 1 – Start with what you know
The strongest forecasts are built on solid foundations. Begin by gathering the data available to you:
- Franchise disclosure documents or resale information from your franchisor
- Trading figures from existing franchisees in a similar territory or demographic
- Any market research or feasibility studies provided during your onboarding process
If you’re taking on an existing franchise, historical accounts are invaluable. If you’re launching fresh, your franchisor should be able to provide realistic benchmarks based on comparable territories.
Step 2 – Identify your revenue streams
Not all franchises earn income in the same way. Before you can forecast sales, you need to clearly define how your franchise generates revenue. Common models include:
- Per transaction or unit sold (retail, food, product-based franchises)
- Service contracts or recurring client agreements (cleaning, care or maintenance franchises)
- Monthly memberships or subscriptions
Map out each income stream separately. This makes your forecasts more accurate and helps you identify which areas have the most growth potential.
Step 3 – Build a monthly sales forecast
Break your forecast down month by month for at least the first 12 months, then annually for years two and three. For each month, estimate:
- Number of customers or transactions. How many clients, jobs, or sales are realistic given your territory, start-up activity and seasonal trends?
- Average transaction value. What is the typical spend per customer or job?
- Monthly revenue. Multiply your expected volume by your average transaction value.
Be conservative in your early months. Most franchises take time to build momentum, lenders and investors will respect a realistic forecast over an overly optimistic one.
Step 4 – Map out your costs
Once you have your revenue projections, you need to understand what it costs to generate that income. Split your costs into two categories:
- Fixed costs – expenses that stay the same regardless of how much you sell, such as franchise fees, rent, insurance and any loan repayments.
- Variable costs – costs that increase in line with sales, such as stock, consumables, delivery or subcontractors.
Understanding the relationship between your revenue and variable costs is key to calculating your gross profit margin (the percentage of each pound of revenue left after covering direct costs).
Step 5 – Calculate your profit projections
With revenue and costs mapped out, you can now calculate your projected profit at each stage:
- Gross profit = Revenue minus variable costs
- Net profit = Gross profit minus fixed costs
This tells you not just whether your franchise can be profitable, but when. It also lets you identify the months where cash flow may be tighter, so you can plan correctly.
Step 6 – Review and adjust regularly
A forecast is not a one-off exercise. As your franchise trades, compare your actual figures against your projections each month. If there are significant differences, in either direction, revisit your assumptions and update accordingly. Regular review keeps your business planning grounded in reality.
Final thoughts
Forecasting sales and profits for your franchise doesn’t need to be complicated, but it does require care and honesty. A well-constructed forecast gives you clarity on your financial journey, supports conversations with lenders and helps you manage your business with confidence from day one.
