Contribution Margin Explained: The Number That Tells You Whether a Sale Is Worth Making
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).
Arcade Bar Bookkeeping: Why Barcades Fail the Regular Bar Playbook
A barcade runs two businesses with opposite cost structures — liquor at a 20–24% pour cost and games at near-zero marginal cost. How to split the chart of accounts, book token sales as deferred revenue with ASC 606 breakage, expense machines via Section 179 or bonus depreciation, and test whether blended margin beats a plain bar's 10–15% net.
GMROI Explained: The Gross Margin Return on Inventory Investment Formula and 2026 Benchmarks
GMROI measures gross profit generated per dollar of average inventory cost; a GMROI above 3.0 is generally strong, below 1.0 means inventory is destroying margin dollars, and typical category ranges run from 1.2 in grocery to 6.5+ in electronics.
Leather Goods Maker Bookkeeping: Why Your Real Material Cost Isn't What You Paid Per Hide
A 50-square-foot hide costing $450 landed with a 64% yield rate has a real material cost of $14.06 per usable square foot, not the $9.00 the invoice implies — the gap driving margin surprises as 2026 tariffs and a shrinking U.S. cattle herd push leather prices up roughly 22%.
LLM API Costs Are COGS, Not Overhead: A Gross Margin Guide for AI Wrappers
LLM inference is a variable cost of delivering your product, not software overhead — ICONIQ's 2026 data puts AI product gross margins at a 52% industry average, well below the 70-80% typical of traditional SaaS.
Micron FY2026 Q3 Earnings: Revenue Rose 346%. The Cost of Making the Chips Rose 10%.
Micron's fiscal Q3 2026 revenue rose 345.7% to $41.46 billion while cost of goods sold rose only 10.5% to $6.40 billion, lifting GAAP gross margin from 37.7% to 84.6% and net income to $28.24 billion — a margin built on DRAM pricing, not cost structure, in a business that posted a negative 9.1% gross margin as recently as FY2023.
Palantir Q1 2026 Earnings: An 85% Growth Rate, a 53% Net Margin, and a Balance Sheet That Still Says It Has Never Made Money
Palantir's Q1 2026 revenue grew 84.7% to $1.633 billion while total costs grew only 24%, lifting operating margin to 46.2% and net margin to 53.7% — a net margin that exceeds the operating margin because interest income adds $134.6 million and the effective tax rate is just 1.4%, against an accumulated deficit that still stands at $2.69 billion.
Reupholstery Shop Bookkeeping: Bench-Time Costing and the Overhead Trap
A wingback chair takes 7-8 yards of fabric and a sofa 15-22, but shops that price by materials plus a flat labor guess routinely underbill by 20-30% because the fully burdened labor rate and per-job overhead never get calculated — only the fabric receipt does.
Meal Prep Delivery Bookkeeping: Why Your COGS Might Secretly Be Over 100% of Revenue
Meal prep and meal-kit subscriptions must defer prepaid revenue until meals are delivered and roll packaging, delivery, labor, and spoilage into COGS — early-stage operators who skip this often find total COGS above 55%, sometimes exceeding 100% of revenue on specific SKUs.
Independent Bookstore Bookkeeping: How to Protect a 2-10% Net Margin
Independent bookstores net just 2-10% per the ABA's ABACUS survey, even with 40-50% gross margins. A practical bookkeeping guide to the transaction types that erode that margin — sale-or-return vendor credits, expiring co-op advertising funds, consignment and trade-credit liabilities — plus the 4-6x inventory turnover benchmark that predicts trouble early.
FTC Fee Transparency Rules and NYC's 43% Delivery Cap: What Restaurants Need to Know in 2026
The FTC's April 2026 ANPRM targets hidden food-delivery fees while a new NYC law raises the cap on platform charges to restaurants from 23% to 43%. What each change means, why a $50 order can net $41 or $28.50 depending on fee tier, and how to record gross sales and platform fees correctly.
Board Game Cafe Bookkeeping: Cover Charges, Food, Retail & Game Library Depreciation
Board game cafes blend three businesses — admission fees, food and beverage, and retail — and each needs its own revenue and COGS account; the game library itself should be capitalized and depreciated over 3-5 years, not expensed, while shrink-wrapped retail copies stay inventory.
