Depreciation
Methods and strategies for depreciating fixed assets including straight-line, MACRS, and accelerated depreciation
Commercial Diving Company Bookkeeping: Saturation Gear Depreciation, Hazard Pay, and Job Costing
Commercial diving companies that depreciate saturation systems on a flat calendar schedule, lump hazard pay and depth pay into a single wages line, or book topside support crew as overhead routinely misprice their bids — this guide covers usage-based depreciation for saturation gear, the diver pay stack, and job-costing topside labor specific to commercial dive operations.
Scuba Dive Shop Bookkeeping: Why Certification Training, Not Gear Sales, Keeps the Doors Open
Dive shops that book prepaid certification fees as revenue on receipt, lump training and retail into one sales account, or depreciate rental gear like retail inventory routinely understate their true profitability — this guide covers deferred revenue for course fees, tank-testing cost tracking, and instructor pay classification specific to dive centers.
Bookkeeping for VR Arcades: Deferred Deposits, Per-Station Depreciation, and Revenue by Stream
How VR arcades and location-based entertainment venues should keep their books — split revenue across six streams, book party deposits as deferred-revenue liabilities, depreciate each $50,000+ station separately, and track revenue per available station hour, the LBE equivalent of a hotel's RevPAR.
Equipment Rental Fleet Bookkeeping: MACRS Depreciation and Section 179
Equipment rental fleets should capitalize purchases as depreciating assets tagged to individual unit IDs, apply MACRS as the default recovery schedule, use Section 179 (up to $2,560,000 in 2026) plus 100% bonus depreciation to front-load deductions, and track time and financial utilization per asset to know which units are actually earning their keep.
GPU Depreciation Schedules, Explained: How One Estimate Turns a 60% Margin Into a $1 Billion Loss
CoreWeave booked $5.13 billion in revenue and a roughly 60% adjusted EBITDA margin in 2025 — and still reported a net loss over $1 billion, driven by $2.45 billion of depreciation. This guide explains how GPU useful-life estimates (4 vs. 6 years) swing reported expenses by ~$30 million per 10,000 GPUs, why Amazon and Meta moved their server lives in opposite directions, and how any equipment-owning business should set honest depreciation assumptions under 2026 Section 179 and bonus depreciation rules.
GPU Depreciation Schedules Explained: How Neoclouds Turn One Accounting Estimate Into Billions in Profit
CoreWeave depreciates GPU servers over 6 years, Lambda over 5, and Nebius over 4 — a difference in useful-life estimates that can shift reported profit by tens of millions of dollars per 10,000-GPU fleet without any cash changing hands, and sits at the center of Michael Burry's $176 billion overstated-depreciation claim against major AI infrastructure spenders.
Self-Storage Cost Segregation and 100% Bonus Depreciation: A 2026 Owner's Guide
Cost segregation studies routinely move 16–24% of a self-storage facility's purchase price off the 39-year schedule into 5- and 15-year property. With 100% bonus depreciation permanently restored by the OBBBA for property placed in service after January 19, 2025, a $1 million acquisition can produce roughly $200,000 in first-year deductions — about $74,000 in tax savings at a 37% rate. Here's how the studies work, what they cost, and the recapture math to run before selling.
Driving School Bookkeeping: Deferred Revenue, Dual-Control Vehicles, and the 1099 Question
A $650 prepaid lesson package is a liability, not revenue, until the lessons are delivered. How driving schools handle deferred revenue, choose between Section 179 (up to $12,200 for light vehicles, $32,000 for 6,001–14,000 lb GVWR in 2026) and standard mileage on dual-control cars, classify instructors as 1099 or W-2 under the IRS three-factor test, budget for state surety bonds ($2,000–$50,000), and track the two KPIs — revenue per vehicle-hour ($70+ target) and instructor utilization (75–85%) — that predict margins.
E-Bike and Scooter Rental Fleet Bookkeeping: Depreciation, Unit Economics, and Breakeven
Rental e-bikes and scooters are fixed assets, not inventory — and useful life ranges from under two months for early shared scooters to 2–3+ years for reinforced fleet hardware. How micromobility operators should structure a chart of accounts that separates batteries, theft, and field-ops labor, calculate contribution per vehicle per day, book damage deposits as liabilities, and find breakeven on blended seasonal utilization rather than peak-week numbers.
E-Bike and Scooter Rental Fleet Bookkeeping: Depreciation, Per-Ride Economics, and the Path to Breakeven
A chart-of-accounts and depreciation framework for e-bike and scooter rental fleets, showing how to track vehicles by acquisition cohort, calculate gross margin per ride, and model a realistic path to breakeven by year three.
EV Charging Station Bookkeeping: The Real Math Behind Per-kWh Margins, Demand Charges, and Payback Period
Demand charges can account for 30–70% of a commercial electricity bill and add roughly $9,000 to a single month when six DC fast chargers peak simultaneously — yet most operators blend them into one utilities account. How to book charging revenue against per-kWh COGS, track the Section 30C credit that now sunsets June 30, 2026, and model realistic payback periods for Level 2 ($4,500–$12,000/port) and DC fast chargers ($90,000–$200,000/port).
The Short-Term Rental Loophole in 2026: How W-2 Earners Offset Income with Material Participation and 100% Bonus Depreciation
A walkthrough of the Section 469 seven-day rule, the three realistic material participation tests, and how the One Big Beautiful Bill Act's permanent 100% bonus depreciation lets short-term rental owners offset W-2 income — plus the bookkeeping habits that survive an IRS audit.
