Lenders, investors, and your own budget all demand a picture of future profitability before that profit exists. A pro forma income statement answers that demand. It projects revenue, expenses, and profit for a future period, or restates past results to strip out a one-time event. The term is Latin. “Pro forma” means “as a matter of form,” per Merriam-Webster. It combines Latin pro (“for”) and forma (“form”), per Etymonline.
This guide explains the pro forma income statement in plain terms. It walks through a corrected worked example, the two forecasting methods, the core formulas, and how startups and acquirers use these projections. Harvard Business School Online defines pro forma statements as forward-looking forecasts built on assumptions rather than fact, which is exactly why they are so useful for planning.
What Is a Pro Forma Income Statement?
A pro forma income statement is a projected income statement showing expected revenue, expenses, and profit for a future period. It can also be a restated historical statement adjusted for a specific event. Businesses use it for budgeting, forecasting, and evaluating the financial impact of mergers, acquisitions, and new investments.
There are two flavors. The forward-looking version projects future results for budgets, business plans, and fundraising. The adjusted-historical version restates past results to remove non-recurring items or to model a completed or proposed transaction. Both rely on assumptions, so both are planning tools, not guarantees.
What Are the Three Pro Forma Financial Statements?
Pro forma financial statements are three linked projections: the income statement, the balance sheet, and the cash flow statement. The income statement is the profitability core where planning usually starts, and it is this page’s focus. The pro forma balance sheet projects assets, liabilities, and equity. The pro forma cash flow statement projects liquidity across the period.
What Does a Pro Forma Income Statement Look Like? (Example and Template)
A pro forma income statement reads as a top-to-bottom waterfall: revenue at the top, each cost subtracted in order, and profit at the bottom. The table below is a reusable template. It starts with $1,000,000 in current sales, applies 10% growth, and works down to the addition to retained earnings using a 30% illustrative tax rate.
| Line item | Formula | Amount |
|---|---|---|
| Projected Revenue | Current Sales × (1 + Growth Rate) | $1,100,000 |
| Less: Cost of Goods Sold (COGS), 60% of sales | Sales × COGS % | $660,000 |
| Gross Profit | Revenue − COGS | $440,000 |
| Less: Selling, General & Administrative (SG&A), 20% of sales | Sales × SG&A % | $220,000 |
| Operating Income (EBIT) | Gross Profit − SG&A | $220,000 |
| Less: Interest Expense | given | $20,000 |
| Pre-tax Income (EBT) | EBIT − Interest | $200,000 |
| Less: Taxes (30%, illustrative) | EBT × Tax Rate | $60,000 |
| Net Income | EBT − Taxes | $140,000 |
| Less: Dividends | given | $50,000 |
| Addition to Retained Earnings | Net Income − Dividends | $90,000 |
COGS is the direct cost of producing what you sell. EBIT means earnings before interest and taxes. EBT means earnings before tax. Tax applies to pre-tax income, not to gross profit, so the order matters. The 30% rate above is illustrative only. The current U.S. federal corporate income tax rate is a flat 21% for tax years beginning after December 31, 2017, under 26 U.S.C. § 11. For the rules behind that rate, see our US tax code explainer.
How Do You Prepare a Pro Forma Income Statement?
Preparing a pro forma income statement takes five steps. First, project revenue. Second, estimate COGS and gross profit. Third, project operating expenses. Fourth, deduct interest, then apply tax to pre-tax income. Fifth, subtract dividends to find the addition to retained earnings. Each step maps to a row in the table above.
- Project revenue: Current Sales × (1 + Growth Rate) gives the $1,100,000 top line.
- Estimate COGS and gross profit: subtracting $660,000 in COGS leaves $440,000 in gross profit.
- Project operating expenses: subtracting $220,000 in SG&A leaves $220,000 in operating income (EBIT).
- Deduct interest, then tax: $20,000 of interest gives $200,000 EBT, and 30% tax on EBT gives $140,000 net income.
- Subtract dividends: $140,000 minus $50,000 in dividends leaves a $90,000 addition to retained earnings.
How Does the Percent-of-Sales Method Work?
The percent-of-sales method assumes most costs move in direct proportion to sales. You forecast revenue, express each line item as its historical percentage of sales, then apply those percentages to projected sales. It fits quick forecasts and businesses with stable cost ratios. Its weakness is that fixed costs like rent and insurance do not scale with revenue.
That weakness is exactly where the next method comes in. When fixed costs are a large share of the base, treating them as a flat percentage of sales overstates costs in good years and understates them in lean ones.
How Does the Fixed and Variable Cost Method Work?
The fixed and variable cost method splits costs into fixed and variable, then projects each on its own logic. Fixed costs like rent, insurance, base salaries, and depreciation stay constant. Variable costs like materials, direct labor, commissions, and shipping scale with output. The backbone formula is Total Cost = Fixed Costs + (Variable Cost per Unit × Units Sold).
This method also unlocks break-even analysis. Contribution margin equals sales minus variable costs. Dividing total fixed costs by the per-unit contribution margin gives the break-even point, the unit volume where profit reaches zero.
Which Method Should You Use?
Use percent-of-sales for speed and fixed-and-variable for accuracy. Most businesses blend the two: they forecast variable costs as a percent of sales and model fixed costs directly. Businesses with high fixed costs need steady sales to cover them, so operating leverage should guide your choice.
| Method | Best for | Main weakness |
|---|---|---|
| Percent-of-sales | Quick forecasts, stable cost ratios | Treats fixed costs as if they scale with sales |
| Fixed and variable cost | Accuracy, scenario planning, operating leverage | Needs more cost detail and data |
| Blended | Most operating businesses | Requires splitting costs by behavior |
What Are the Key Pro Forma Projection Formulas?
Five formulas drive every pro forma income statement. They move from projected sales down to ending retained earnings. The table below collects them for quick reference.
| Metric | Formula |
|---|---|
| Projected sales | Current Sales × (1 + Growth Rate) |
| Gross profit projection | Projected Revenue − Projected COGS |
| Gross margin % | Gross Profit ÷ Revenue × 100 |
| Projected net profit | Pre-tax Income − Taxes, where Pre-tax Income = Revenue − COGS − Operating Expenses − Interest |
| Retained earnings projection | Ending Retained Earnings = Beginning Retained Earnings + Net Income − Dividends |
How Do You Build a Pro Forma Income Statement in Excel?
You build a pro forma income statement in Excel by separating assumptions from calculations. Put a block of editable cells at the top for growth rate, COGS %, SG&A %, and tax rate. Lay the timeline across columns. Write formulas that reference the assumption cells so the whole model flexes when an input changes. Add best, base, and worst scenario columns.
Color-code input cells so they stand out from calculated cells, and bold every subtotal: gross profit, EBIT, EBT, and net income. Many free templates exist, and starting from one saves setup time.
How Do Startups Use a Pro Forma Income Statement in a Business Plan?
Startups with no operating history build revenue bottom-up from drivers like units, pricing, and sales pipeline, not from historical percentages. Investors and lenders expect these projections inside the business plan. A bottom-up forecast multiplies expected units by price, then layers in costs, so every number traces back to an assumption a reader can challenge.
Pro forma projections also help founders compare outcomes across entity types before they commit. Our guide to LLC vs C corp shows how the choice changes what appears as taxable profit.
How Are Pro Forma Financial Statements Used in Mergers and Acquisitions?
In mergers and acquisitions (M&A), pro forma financial statements model the combined company as if the deal had already closed. They use the adjusted-historical flavor, folding in synergies, new acquisition-financing interest, and purchase-accounting adjustments. Public acquirers face a hard rule: the U.S. Securities and Exchange Commission (SEC) requires pro forma statements for a significant acquisition.
The SEC defines significant as crossing a 20% threshold on the investment, asset, or income test under 17 CFR 210.11-01. The SEC’s 2020 overhaul of these pro forma rules under Regulation S-X, Article 11 took effect January 1, 2021, per the SEC.
Are Pro Forma Statements GAAP Compliant?
No. Pro forma statements are not GAAP compliant. GAAP stands for Generally Accepted Accounting Principles. Pro forma figures rely on assumptions and may exclude items GAAP requires, so investors treat them with caution. Public companies that present non-GAAP figures must follow SEC Regulation G and reconcile each measure to the closest GAAP number.
The Financial Accounting Standards Board (FASB) codification has been the single source of authoritative U.S. GAAP since 2009, and a series of SEC rules governs how public companies present pro forma figures. The table below traces that regulatory arc.
| Milestone | Date | Source |
|---|---|---|
| SEC Chairman Arthur Levitt’s “The Numbers Game” speech warns that earnings management erodes reporting quality | September 28, 1998 | SEC speech archive |
| SEC cautionary guidance warns “pro forma” press-release figures have no defined meaning and can mislead investors | December 4, 2001 | SEC Release No. 33-8039 |
| SEC’s first pro forma enforcement action, against Trump Hotels & Casino Resorts, over an $81.4 million one-time gain | January 16, 2002 | SEC Press Release 2002-6 |
| Sarbanes-Oxley Act Section 401(b) directs the SEC to regulate pro forma disclosures | July 30, 2002 | Sarbanes-Oxley Act of 2002 |
| SEC votes to adopt Regulation G | January 15, 2003 | SEC Press Release 2003-6 |
| Regulation G takes effect, requiring reconciliation of non-GAAP figures to the closest GAAP measure | March 28, 2003 | SEC Release No. 33-8176 |
| SEC recognizes FASB’s standards as “generally accepted” under Sarbanes-Oxley Section 108 | April 25, 2003 | SEC Release No. 33-8221 |
| FASB Accounting Standards Codification becomes the single authoritative source of U.S. GAAP | July 1, 2009 | FASB |
| SEC adopts its overhaul of pro forma rules under Regulation S-X, Article 11 (Release No. 33-10786) | May 20, 2020 | SEC.gov |
| The Article 11 overhaul takes effect | January 1, 2021 | SEC.gov |
Regulation S-K Item 10(e) adds that inside SEC filings the comparable GAAP measure must appear with equal or greater prominence than the non-GAAP figure, per 17 CFR 229.10(e). The SEC still advises investors to read full GAAP statements rather than rely on pro forma press-release figures.
