A three-statement financial model links the income statement, the balance sheet, and the cash flow statement into one connected model, so a change in any assumption flows through all three. It is the standard format investors and lenders expect because it shows not just profit, but whether the business actually has the cash to operate. The discount rate you'd use to value those cash flows comes from our free WACC calculator.
Why three statements instead of one
Profit and cash are not the same thing. A business can look profitable on paper and still run out of money, which is why a single projection is not enough. The three-statement model ties performance, position, and liquidity together so reviewers can see the full financial picture and trust that the numbers are internally consistent.
The three statements
Income statement
The income statement shows revenue, costs, and profit over a period. It answers whether the business makes money from operations. Lenders and buyers often normalize its bottom line into EBITDA — our free EBITDA calculator adds interest, taxes, depreciation, and amortization back to net income to get there.
Balance sheet
The balance sheet is a snapshot of what you own and owe at a point in time: assets, liabilities, and equity. It must always balance.
Cash flow statement
The cash flow statement tracks the actual cash moving in and out across operating, investing, and financing activities. It is often the statement lenders study most closely.
Linked financial statements: how they connect
Net income from the income statement flows into retained earnings on the balance sheet and is the starting point of the cash flow statement. Changes in balance sheet items, like receivables or debt, drive cash flow. Because everything links, a single assumption change ripples through the whole model, which is what makes it powerful and what makes errors easy to spot. This structure is the backbone of the financial projections in any serious business plan.
How does a financial model work? One change, traced through
The easiest way to see the machinery is to change one assumption and follow it. Say you raise projected revenue 10%. On the income statement, revenue and net income rise. On the balance sheet, retained earnings grow by the extra profit — but if customers pay on 45-day terms, accounts receivable grows too, because more sales means more money owed to you at any moment. The cash flow statement reconciles the two: it starts from the higher net income, then subtracts the receivables build-up, showing that cash arrived slower than profit. That is the model working as designed — a single optimistic assumption just revealed a working-capital cost that a one-sheet projection would have hidden, which is exactly why lenders and investors insist on the linked version.

Build my financial modelGood to know before you build
- Keep assumptions separate. Drivers belong in one tab, not hard-coded into formulas.
- Build monthly for year one. Then quarterly and annual, which matches what lenders expect.
- Check that the balance sheet balances. If it does not, a link is broken.
- Model working capital explicitly. Receivable and payable timing is where profitable businesses run out of cash, and where reviewers test hardest.
- Track your unit economics. Layer in CAC and LTV to show growth is profitable.
A clean model makes your pitch deck financials and your written business plan consistent and credible. If you would rather have it built right the first time, see our financial modeling service.
