Financial Projections and Forecasting for a Growing Business

A forecast won't predict the future. But financial projections help you plan it: when to hire, how much to spend on marketing, when cash will get tight and how much funding you need. Investors and lenders will ask for them. More importantly, you need them.

This guide is part of our how to scale a business series.

The three core pieces

Piece	Answers
Revenue forecast	How much will we sell, and when?
Profit and loss	Will we make money?
Cash flow forecast	Will we have cash when we need it?

Profit and cash are not the same. A profitable business can still run out of cash. See cash flow management.

Build revenue bottom-up

Start from drivers, not wishes:

• Leads per month, by channel
• Conversion rate from lead to customer
• Average sale value
• Repeat purchases or renewals
• Capacity limits

Example: 200 leads × 15% conversion × $1,500 average sale = $45,000 per month.

This also shows where growth comes from. Lift conversion by answering leads faster and the forecast improves without more ad spend. See lead nurturing.

Map costs

• Direct costs: materials, delivery staff, payment fees
• Operating costs: rent, software, salaries, insurance
• Growth costs: marketing, hiring, new locations
• Taxes and debt repayments

Tie marketing spend to targets using customer acquisition cost and advertising budgets.

Forecast cash monthly

List when money actually comes in and goes out. Include deposits, payment terms, seasonal swings (in Calgary, think winter for some trades and Stampede for hospitality) and one-off purchases.

Test scenarios

Build three versions:

Scenario	Assumption example
Base	Current trends continue
Upside	Conversion rises, new offer succeeds
Downside	Sales drop 20%, costs rise, a big client leaves

See scenario planning.

State your assumptions

Write them down: "Conversion stays at 15%," "Two hires in Q2," "Prices rise 5% in January." When results differ, you'll know which assumption was wrong.

Use the forecast

• Decide when you can afford a hire (hiring)
• Set SMART goals
• Plan funding (debt vs. equity)
• Support investor conversations (pitch deck)

Update monthly

Compare actuals to forecast every month. Adjust the next 12 months. A forecast that never changes is fiction.

Example: forecasting a new hire (illustrative)

A Calgary landscaping company forecasts spring demand from last year's leads plus a new radio campaign. The model shows it can fund a crew lead from April if conversion stays above 25%. The owner hires in March and tracks conversion weekly.

Mistakes to avoid

• Hockey-stick optimism. Forecasts where sales suddenly explode without a clear driver lose credibility with lenders and investors.
• Forgetting timing. Revenue booked in March but paid in May changes your cash position completely.
• Leaving out growth costs. New hires need equipment, training and time to become productive. Budget for the ramp-up.
• Building it once for a bank. A forecast is a management tool. Use it every month, not just when you need a loan.
