How to calculate economic profit

Accounting profit is what financial statements emphasize: revenue minus explicit expenses. Auditors and tax filings focus on cash and recorded expenses—not what you could have earned in another job or investment.

Economic profit subtracts implicit opportunity costs on top of explicit costs. That is why a small business can show positive accounting profit while economic profit is negative: the owner’s forgone market wage exceeds the profit left in the firm.

• Accounting profit only — “Did cash revenue beat cash expenses?”
• Economic profit — “Did this use of time and capital beat the next-best alternative?”
• Zero economic profit — earning a normal return; not the same as zero accounting profit

In Revenue & costs mode, accounting profit and economic profit appear together so you can compare them at a glance—helpful for economic profit vs accounting profit assignments and for checking whether a side business truly beats your alternatives.

Explicit costs are paid in cash or recorded on the books—wages to employees, rent checks, materials, loan interest, utilities, and taxes. They flow into accounting profit because they reduce revenue on the income statement.

Implicit costs are opportunity costs: the value of resources you already control or time you could spend elsewhere. No check is written, but they still belong in the economic profit calculation.

• Explicit (cash) — vendor invoices, payroll, lease payments, COGS, marketing spend
• Implicit (opportunity) — forgone salary, forgone investment return on owner equity, imputed rent on owner-occupied space

Common implicit examples:

• Forgone salary — market wage you could earn as an employee
• Forgone return on equity — return if capital stayed in a portfolio instead of the firm
• Imputed rent — market rent forgone when you use your own building
• Forgone interest — financing cost of capital locked in inventory or equipment

Homework often states one large implicit figure (for example forgone income of $10,000,000). Enter it in the implicit cost field only—do not also book it as an explicit expense or you will double-count.

If implicit costs are uncertain, start with accounting profit, then try a few plausible opportunity-cost amounts by changing the implicit cost field to see how economic profit moves.

In corporate finance, economic profit is often framed as value created after a capital charge: NOPAT − (invested capital × WACC). When ROIC > WACC, the spread times invested capital equals positive economic profit—the firm earns more than investors require for the risk of the capital deployed.

This calculator can derive NOPAT from EBIT and a tax rate or accept NOPAT directly. For invested capital, use average of beginning and ending IC (common in case studies) or a single IC figure when the problem gives one balance.

• WACC — weighted average cost of debt and equity; estimate with our WACC calculator if the prompt does not provide it
• ROIC — NOPAT ÷ invested capital; shown in results with the spread versus WACC
• EVA — usually the same NOPAT − capital×WACC definition; see FAQ below

Choose From accounting profit when the problem already gives accounting profit (revenue minus explicit costs, or a stated “accounting profit” line) and only asks you to subtract implicit costs.

Example: accounting profit $30,000, implicit costs $10,000 → economic profit $20,000. The bakery preset uses revenue mode because the table lists revenue and explicit costs separately; if your table only shows accounting profit $30,000 and implicit $10,000,000, accounting-profit mode is faster.

• Revenue & costs — separate revenue and explicit expense lines
• From accounting profit — one profit number plus implicit cost
• Corporate — NOPAT, invested capital, WACC (not revenue-based)

Table problems usually give revenue (or price × quantity), several explicit cost rows, and sometimes a single implicit / opportunity cost line in the footnotes.

Example table (micro):

• Total revenue — $120,000
• Explicit costs (sum of wages, supplies, rent) — $90,000
• Accounting profit — $30,000 (revenue − explicit)
• Implicit cost (forgone salary stated in prompt) — $10,000,000
• Economic profit — $30,000 − $10,000,000 = −$9,970,000

Enter revenue $120,000, explicit $90,000, and implicit $10,000,000 in Revenue & costs mode, or load the Bakery homework preset.

Enter totals from your worksheet manually—the calculator does not import table images or files. If only accounting profit is given, switch to From accounting profit mode.

Graph and area problems still reduce to dollars:

1. Read price (P) and quantity (Q) at the chosen point → total revenue = P × Q.
2. Read average total cost (ATC) at that quantity → explicit costs ≈ ATC × Q when the problem defines total cost that way (follow your instructor’s labels).
3. Add any implicit cost stated in text (forgone wage, alternative investment).
4. Compute accounting profit = revenue − explicit costs; economic profit = accounting profit − implicit costs.

Shaded “profit” or “loss” rectangles on diagrams are not automatically opportunity cost—only subtract implicit cost when the question names it.

Enter the dollar amounts in the calculator once you have converted the graph to numbers.

In the long run under perfect competition, free entry and exit push firms toward zero economic profit: price equals minimum average total cost, and owners earn a normal return (opportunity cost covered, but no extra economic profit).

Short run vs long run:

• Short-run positive economic profit — attracts new firms; supply shifts until profit is competed away
• Short-run losses (negative economic profit) — some firms exit until remaining firms reach zero economic profit
• Zero economic profit ≠ zero accounting profit — explicit depreciation or recorded costs can still leave positive accounting profit on statements

Use dollar inputs from your graph or table in the calculator; the theory tells you what equilibrium to expect, not a separate formula.

Economic profit sits between intro micro (opportunity cost) and corporate valuation (cost of capital). These Ordio tools answer adjacent questions without duplicating the same formula:

• Profit margin calculator — margin % on sales, not opportunity cost
• Marginal cost calculator — incremental cost per extra unit (ΔTC ÷ ΔQ)
• Comparative advantage calculator — who should produce which good (trade-offs, not firm profit)
• Break-even calculator — units to cover fixed and variable costs
• WACC calculator — cost of capital for corporate mode
• DCF calculator — multi-period discounted cash flow (not single-period economic profit)
• ROA calculator — return on assets (denominator differs from invested capital in ROIC)
