Debt-to-Equity Ratio and Return on Equity

How architecture firms measure their debt position through the debt-to-equity ratio and evaluate owner returns through return on equity (ROE). Covers formulas, interpretation thresholds, and strategic implications for firm health and growth decisions.

Overview

Why These Two Ratios Belong on Your Radar

Architecture firms live and die by their financial health, but most principals never learned financial analysis in studio. Two ratios cut straight to the core of a firm's stability and performance: the debt-to-equity ratio (D/E) and return on equity (ROE).

The debt-to-equity ratio tells you whether a firm is carrying too much debt relative to what the owners have invested. It's an indicator of how much the firm relies on borrowing. Lenders look at it. Potential partners look at it. And when ownership transition comes around, it becomes a deal-breaker or deal-maker.

Return on equity answers a different question: are the owners getting a worthwhile return on the money they've put into the firm? If you could earn more parking that capital in an index fund, something's wrong with the business model.

How This Connects to the ARE

On the PcM exam, you won't just be asked to define these ratios. You'll face scenarios where a firm's balance sheet data is presented and you'll need to evaluate whether the firm is financially healthy, carrying too much debt, or underperforming for its owners. That means understanding the formulas, knowing healthy thresholds, and making judgment calls about what the numbers mean for strategic decisions.

Where This Fits

These ratios connect directly to balance sheet analysis, profitability metrics, and ownership transition planning. They sit at the intersection of accounting fundamentals and firm management strategy, two areas the ARE tests heavily within PcM.

Essential

The Balance Sheet Foundation Before you can calculate either ratio, you need to understand what feeds them. Both D/E and ROE pull their inputs from the balance sheet, the financial statement that captures a firm's assets, liabilities, and owner's equity at a specific point in time. The fundamental equation: Assets = Liabilities + Owner's Equity Everything a firm owns (assets) was funded either by borrowing (liabilities) or by the owners' investment and accumulated profits (equity). This equation always balances. Always. On a typical architecture firm's balance sheet, you'll see: - Current assets: cash, accounts receivable, work in progress - Fixed assets: equipment, furniture, leasehold improvements - Current liabilities: accounts payable, accrued expenses, current portion of loans - Long-term liabilities: bank loans, lines of credit, equipment financing - Owner's equity: initial investment plus retained earnings minus distributions ## Debt-to-Equity Ratio ### The Formula **Debt-to-Equity Ratio = Total Liabilities / Total...

Scenario 1: The Growth Decision Consider a 20-person firm generating $3,000,000 in net operating revenue. The principals want to open a second office. The expansion requires $400,000 in startup costs: new lease, furniture, technology, and working capital to cover the gap before the new office generates revenue. The firm's current balance sheet shows total liabilities of $380,000 and total equity of $520,000. That's a D/E ratio of 0.73. Healthy. Two paths forward: Path A: Bank Loan. Borrow the full $400,000. New liabilities: $780,000. Same equity: $520,000. New D/E: 1.50. That exceeds the 1.35 guideline. The firm now exceeds debt guidelines, and monthly loan payments add fixed overhead regardless of whether the new office wins projects. Path B: Mixed Funding. Borrow $200,000 and fund the remaining $200,000 from retained earnings (reducing distributions to owners for two years). New liabilities: $580,000. Equity stays at roughly $520,000 (assuming profits continue).

TLDR

D/E Ratio = Total Liabilities / Total Equity. Measures how much debt a firm carries relative to owners' investment.
Keep D/E below 1.35. Liabilities should not exceed equity by more than 35%.
ROE = Net Profit / Total Equity. Measures the percentage return owners earn on their equity.
ROE should meet or exceed the firm's targeted profit. If it doesn't, the owners' capital is underperforming.
Higher debt levels amplify ROE in good times but magnifies losses when revenue drops.
Retained earnings increase equity, which lowers D/E (good) while also lowering ROE (trade-off).
Always evaluate D/E and ROE together. High ROE with dangerously high D/E signals false confidence.
D/E uses total liabilities (current + long-term), not just long-term debt. Don't forget accounts payable and accrued expenses.
The exam tests evaluation, not just calculation. Expect to compute the ratios and then make a strategic judgment about the firm's health.

The Piggy Bank Analogy Imagine you're starting a lemonade stand. You have $100 of your own money (that's your equity). But the stand costs $180 to set up, so you borrow $80 from a friend (that's your debt). Your debt-to-equity ratio is $80 / $100 = 0.80. For every dollar of your own money, you owe 80 cents to someone else. That's manageable. Now imagine you borrowed $150 instead. Your D/E ratio jumps to $150 / $100 = 1.50. You owe more than you put in. If sales are slow next week, you still owe your friend that money. That's risky. The rule of thumb? Keep the D/E ratio below 1.35. That means your borrowed money shouldn't be more than 35% bigger than your own money.
