How to Build the Financial Section of a Business Plan Step by Step

Ask any banker what they read first in a business plan and many will say the numbers. The written sections explain the idea, but the financial section shows whether it can work: how much money is needed, when the business breaks even, whether it can repay a loan and what happens if things go worse than planned.

Many owners approach this section backwards. They start with a revenue target, fill in expenses until the bottom line looks healthy, and paste a few tables into the document. Experienced reviewers spot that immediately. A credible financial section is built forward from drivers you can explain, such as customers, prices, staff hours and quotes, with each statement linked to the next.

This guide shows you how, step by step. To keep it practical, we follow one running example throughout: a new specialty café in Oakville, Ontario, needing $280,000 to open, with 260 customers a day expected in year one. The same method works for a contractor, an agency, a clinic or a tech start-up.

The 12 Steps at a Glance

Step 1: Gather Inputs and Confirm BN Registration

Collect everything the projections will rely on: quotes for equipment and construction, the lease or letter of intent, supplier price lists, wage rates, and historical financial statements if the business already operates. Clean, reconciled books matter; if yours are behind, read our article on bookkeeping mistakes Vaughan businesses keep making before you start.

Confirm your tax registrations too, because several lines in your projections depend on them. Your CRA business number is the nine-digit identifier the Canada Revenue Agency uses for your corporate tax (RC), GST/HST (RT) and payroll (RP) accounts. Lenders usually ask for it. If you are not yet registered, BN registration can be completed through the CRA's Business Registration Online service, and Ontario corporations generally receive a BN when they incorporate through the Ontario Business Registry. Note the expected registration date in your plan.

• RT account: drives HST collected and input tax credits in the cash flow.
• RP account: drives payroll remittance timing.
• RC account: drives corporate tax and instalments for incorporated businesses.

Step 2: Startup Costs and Use of Funds

List every cost needed before opening, supported by quotes, plus a working capital reserve to carry the business until it breaks even and a contingency for overruns.

Steps 3–5: Sales, Cost of Sales and Operating Costs

Step 3: Build a driver-based sales forecast

Never start with a revenue number. Start with the drivers that produce it:

Support each driver with evidence: foot traffic counts, competitor observations, comparable cafés or your own experience. Show the first year monthly, with a ramp-up in the opening months and seasonal patterns.

Step 4: Estimate cost of sales and gross margin

Cost of sales covers coffee, milk, food, packaging and other costs that rise directly with each sale. Our café assumes ingredients at 31% of revenue, plus card processing and packaging at about 4%. Build these from supplier pricing per item, not industry averages alone.

Step 5: Plan payroll and operating expenses

List every role with hours and wage rates, then add employer costs: CPP and EI contributions, vacation pay, and Employer Health Tax once payroll exceeds the exemption. Add rent and occupancy from your lease, plus utilities, insurance, marketing, software, repairs and professional fees. The true cost of labour is often underestimated; our article on fractional CFO services for HVAC and trades in Hamilton shows how to calculate fully loaded labour costs.

Step 6: Projected Income Statement

The income statement combines steps 3 to 5 to show profit. Show revenue and expenses net of HST.

Steps 7–8: Cash Flow and Balance Sheet

Step 7: Cash flow forecast

Profit is not cash. The cash flow forecast shows when money actually moves, month by month. It should include:

• Startup spending and funding: owner equity and loan proceeds in, construction and equipment out.
• Operating cash: sales receipts, supplier payments and payroll, adjusted for payment terms and inventory.
• HST: tax collected, input tax credits and remittances to your RT account under your business number.
• Loan principal and interest payments.
• Owner draws or dividends, if any.

Step 8: Projected balance sheet

The balance sheet shows what the business owns and owes at each year-end: cash, inventory, equipment and leaseholds net of depreciation on one side; loans, payables, HST owing and owner's equity on the other. If it doesn't balance, something in the model is broken. That's why lenders treat a balancing balance sheet as a basic test of a model's integrity.

Step 9: Break-Even Analysis

Break-even tells a lender how much the business must sell to cover all costs before debt payments.

The café's fixed costs in year 1 (wages, rent and fixed overhead) total about $332,400, and each sales dollar contributes 65 cents after ingredients, packaging and card fees. Break-even is therefore about $511,400 a year, or roughly 219 customers a day at a $6.50 average ticket, comfortably below the 260 forecast.

Step 10: Funding Request and Debt Coverage

Lenders then test repayment capacity with the debt service coverage ratio (DSCR): cash available for debt service divided by annual principal and interest. With about $35,300 in annual loan payments:

Many lenders look for a DSCR of at least 1.25x, so the café clears the bar with room to spare.

Steps 11–12: Scenarios, Assumptions and Summary

Step 11: Scenarios and sensitivities

Show what happens if key assumptions are wrong. Change one driver at a time and measure the effect on year-1 EBITDA:

With 10% fewer customers, EBITDA stays positive but falls below the $35,300 needed for loan payments. The plan answers that risk directly: the $30,000 working capital reserve bridges the gap, and staffing hours can be trimmed if traffic lags. Presenting this proactively builds far more lender confidence than hiding it.

Step 12: Document assumptions and summarize

• An assumptions page listing every key input with its source.
• A one-page financial summary at the front: funding needed, revenue, EBITDA, break-even and DSCR.
• Consistency checks: the numbers in the written plan must match the model exactly.
• A live spreadsheet you can update monthly as actual results come in.
