Amazon's Q2 2026: $200.6B net sales (+19.6%) and $62.6B net income (+245%) — but $53.4B of that was a non-operating gain from revaluing its Anthropic stake. Operating income rose 43% to $27.5B as AWS accelerated to 37% growth at a 39.4% margin, while trailing free cash flow turned to a $7.6B outflow on $169B of capex. Modeled line by line in a public Beancount ledger.
Return on Net Assets (RONA = Net Income ÷ Fixed Assets + Net Working Capital) measures whether the equipment, vehicles, and inventory a business owns are actually generating profit. Includes a worked example, rough benchmarks (above 5% acceptable, above 20% outstanding), and how RONA differs from ROA and ROE for capital-intensive small businesses.
Microsoft's FY2026: $331.8B revenue (+18%), a record $133.7B net income, Azure past $100B, and $115.9B of AI capex — nearly 35% of revenue — broken down as an auditable plain-text Beancount ledger.
The quick ratio (acid-test ratio) measures whether a business can cover current liabilities using only cash, marketable securities, and receivables — deliberately excluding inventory and prepaid expenses. Covers the formula with a worked example, why loan covenants often set a quick-ratio minimum instead of a current-ratio one, why 1.0 is the textbook benchmark but fast-turn retailers healthily run 0.3–0.4, and the mistakes that make the ratio misleading.
The asset coverage ratio measures whether tangible assets could repay total debt in a liquidation — [(total assets − intangibles) − (current liabilities − short-term debt)] ÷ total debt. Below 1.0 is a red flag, 2.0 is a common healthy benchmark, and lenders often write a minimum ACR into loan covenants that can trigger technical default.
Alphabet's Q2 2026 revenue was $119.8B (+24% YoY) and net income hit $112.2B (+298%), but roughly $99.0B of that was a non-cash gain on equity securities that the cash flow statement backs right out, leaving operating cash flow at just $39.1B. Google Cloud grew 82% to a ~$99B run-rate at a 35.6% operating margin, while Alphabet halted stock buybacks and raised ~$70B via common stock, its first-ever preferred, and debt to fund a $44.9B capex quarter that turned free cash flow negative. The FY2022–Q2 2026 Beancount ledger shows long-term debt climbing from $10.9B to $98.2B.
The fixed asset turnover ratio — net sales divided by average net fixed assets — measures revenue generated per dollar of PP&E. Capital-intensive businesses typically run 1–3, asset-light ones 5+, and the trend matters more than the level. Here's how to calculate it, benchmark it, and avoid the bookkeeping errors that distort it.
Inventory turnover ratio = COGS ÷ average inventory, and it shows how many times a business sells through its stock each year. This guide covers the formula, converting turnover to days sales of inventory, industry benchmarks from 2–4 turns (industrial parts) to 10–20+ (grocery), and why slow-moving stock costs 20–30% of its value annually to hold.
The quick ratio (acid-test ratio) strips inventory and prepaid expenses from current assets to test whether cash, receivables, and marketable securities alone can cover current liabilities. Includes the formula, a worked example where a 2.5 current ratio hides a 1.0 quick ratio, industry benchmarks, and the aged-receivables blind spot.
Contribution margin is sales revenue minus variable costs — the per-unit number that drives pricing, break-even analysis, and product-mix decisions. Learn the formula, how it differs from gross margin, common calculation mistakes, and typical ratios by industry (70–90% for software, 25–50% for manufacturing).
ROIC measures how efficiently a business turns debt and equity into after-tax operating profit — NOPAT divided by invested capital. Learn the formula, why it beats ROI and ROE, the WACC benchmark that separates value creators from value destroyers, and the five calculation mistakes owners make most.
The sustainable growth rate (SGR = retention rate × ROE) sets the maximum revenue growth a business can fund from its own profits without new debt or equity, with most healthy companies landing between 10% and 25% a year.
