The 3 financial statements are all linked and dependent on each other. In financial modeling, your first job is to link all three statements together in Excel, so it’s critical to understand how they’re connected.
Net Income & Retained Earnings
Net income from the bottom of the income statement links to the balance sheet and cash flow statement. On the balance sheet, it feeds into retained earnings and on the cash flow statement, it is the starting point for the cash from operations section.
PP&E, Depreciation, and Capex
Depreciation and other capitalized expenses on the income statement need to be added back to net income to calculate the cash flow from operations. Depreciation flows out of the balance sheet from Property Plant and Equipment (PP&E) onto the income statement as an expense, and then gets added back in the cash flow statement.
For this section of linking the 3 financial statements, it’s important to build a separate depreciation schedule.
Capital expenditures add to the PP&E account on the balance sheet and flow through cash from investing on the cash flow statement.
Working Capital
Modeling net working capital can sometimes be confusing. Changes in current assets and current liabilities on the balance sheet are related to revenues and expenses on the income statement but need to be adjusted on the cash flow statement to reflect the actual amount of cash received or spent by the business. In order to do this, we create a separate section that calculates the changes in net working capital.
Financing
This can be a tricky part of linking the three statements and requires some additional schedules. Financing events such as issuing debt affect all three statements in the following way: the interest expense appears on the income statement, the principal amount of debt owed sits on the balance sheet, and the change in the principal amount owed is reflected on the cash from financing section of the cash flow statement.
In this section, it’s often necessary to model a debt schedule to build in the necessary detail that’s required.
Cash Balance
This is the final step in linking the 3 financial statements. Once all of the above items are linked up properly, the sum of cash from operations, cash from investing, and cash from financing are added to the prior period closing cash balance, and the result becomes the current period closing cash balance on the balance sheet.
This is the moment of truth when you discover whether your balance sheet balances!
