====== Revenue Tonne-Kilometers (RTK) ======
Revenue Tonne-Kilometers (RTK) is a key performance metric used in the transport industry, particularly for companies that move goods. Think of it as the ultimate work receipt for a [[freight]] or [[logistics]] business. It measures the total volume of paid cargo traffic by multiplying the weight of the cargo in tonnes by the distance it is transported in kilometers. So, if a company flies 10 tonnes of cargo for 5,000 kilometers, it has generated 50,000 RTKs. This figure is crucial because it represents the actual revenue-generating activity of a company's transport operations, stripping away the noise of pricing strategies or fuel surcharges. It tells you, in a single number, how much //stuff// the company moved and how //far// it moved it. It’s the physical heartbeat of a cargo airline, a railway, or a long-haul trucking firm, and for an investor, it’s a powerful tool for gauging a company's operational health and market demand. Its sibling metric for the passenger business is [[Revenue Passenger Kilometers (RPK)]].
===== Why Does RTK Matter to an Investor? =====
For a [[value investor]], looking beyond the headline numbers like revenue and profit is essential. Operational metrics like RTK provide a ground-level view of a business's performance and competitive standing.
==== A Pure Measure of Demand and Growth ====
RTK is a direct measure of business volume. If a company's RTK is consistently growing, it’s a strong sign that demand for its services is increasing. This growth can come from two sources:
  * Carrying more tonnes (winning more customers or larger shipments).
  * Carrying cargo over longer distances (expanding routes or services).
Because RTK is a physical measure (tonnes x km), it allows for a purer comparison of growth over time and between companies, without being distorted by fluctuating freight rates, currency exchange rates, or fuel costs. It answers the simple, vital question: "Is this business doing more work this year than it did last year?"
==== Gauging Operational Efficiency ====
RTK is not just a standalone number; it's a key ingredient in other critical efficiency ratios. The most important of these is the [[cargo load factor]]. This is calculated by dividing the RTK by the Available Tonne-Kilometers (ATK), which represents the total carrying capacity of the company.
A high and improving load factor shows that the company is getting better at filling up its planes, trains, or trucks. It's a sign of a well-managed network and strong demand, indicating that expensive assets are being used profitably instead of moving empty space.
===== Putting RTK into Practice =====
Understanding the concept is great, but applying it is what creates value. Let's break down how you can use RTK to analyze a potential investment.
==== The Formula and an Example ====
The calculation is refreshingly simple:
**RTK = Total Tonnes of Revenue Cargo x Distance Transported in Kilometers**
//Example:// Let’s say ‘Warren’s World-Wide Cargo’ had two shipments in a month:
  - Shipment 1: 20 tonnes of electronics from Frankfurt to Shanghai (approx. 8,500 km).
  - Shipment 2: 5 tonnes of luxury watches from Geneva to New York (approx. 6,200 km).
The total RTK for the month would be:
  * (20 tonnes x 8,500 km) + (5 tonnes x 6,200 km) = 170,000 + 31,000 = **201,000 RTKs**.
Note: While American investors are used to imperial units (tons and miles), RTK is the global standard used by international bodies and for comparing transport companies worldwide.
==== From Kilometers to Cash ====
RTK is a physical metric, but it’s directly linked to the money a company makes. By itself, RTK tells you about volume. To understand pricing power, you need to look at **yield**.
**Yield = Total Cargo Revenue / Total Revenue Tonne-Kilometers (RTK)**
Yield tells you how much money the company earns for every tonne-kilometer of work it performs. It's the "price" component of the revenue equation. A company's [[operating revenue]] can therefore be seen as **RTK (Volume) x Yield (Price)**.
An investor’s dream is to see a company growing both its RTK (selling more) and its [[yield]] (selling it for more). Conversely, a company growing its RTK while its yield plummets might be chasing volume at any cost—a potential red flag.
===== The Value Investor's Checklist =====
When you see RTK figures in a company’s report, here’s how to use them to make smarter decisions:
  * **Look for the Trend:** Is the company’s RTK growing, shrinking, or flat over the past few years? How does that trend compare to its closest competitors? A company consistently growing its RTK faster than its peers is likely gaining market share.
  * **Analyze the Yield:** Don’t look at RTK in a vacuum. A company might boost RTK by taking on low-margin cargo. Check the yield. A rising RTK combined with a stable or rising yield is a sign of healthy, profitable growth.
  * **Check the Load Factor:** How full are the planes or trains? Compare RTK to ATK to find the cargo load factor. A high load factor (e.g., above 60-70% for air freight) suggests efficient operations and strong demand.
  * **Context is King:** RTK is a powerful [[leading indicator]] for the broader economy. It's highly sensitive to the [[economic cycle]], as global trade and shipping activity rise in booms and fall in recessions. Assess the company’s RTK performance in the context of the current economic environment. Is it outperforming a weak market or just riding a strong wave?
