How much does it cost to buy a used storage container?
Rising storage needs push more people to look for cheaper options, but the real cost of buying a used storage container is often misunderstood.
A used 20ft storage container generally costs $1,500–$3,000, while a used 40ft container costs $2,000–$4,500 depending on condition, location, and market demand.
When people ask me this question, they often expect one simple number. The truth is, the cost varies greatly. I have worked with clients who bought 40ft containers for $2,500, and others who paid nearly double. What matters most is the condition, age, and whether the container is shipping-grade or storage-grade. Then, add transport fees — which can be $200–$500 for every 50 miles — and you have your real cost.
Are used 40ft containers worth it?
More space means bigger savings in rent, but only if the container lasts long enough to make it worth it.
Used 40ft containers are often worth buying for storage or modification projects, saving 30%–60% compared to new ones.
I often recommend used 40ft containers for people with enough space to place them. New 40ft units usually cost $5,000–$8,000. A good used one can be half that price. The key is to know how you will use it. If it stands outdoors for many years, proper coating and maintenance are needed. In my experience, clients who repurpose these containers into offices, workshops, or mobile storage units often achieve returns by avoiding warehouse rent and still reselling them later.
Factors that decide if a used 40ft is worth it
| Factor | Impact on Value | Notes |
|---|---|---|
| Structural integrity | Very high | Look for no bending in walls or frame |
| Rust level | High | Surface rust can be treated, deep corrosion is costly |
| Modification potential | Medium | Easy for housing or workspace conversion |
| Age | High | 3-7 years old offers good balance of durability & price |
| Transport cost | Medium | May reduce savings if too far from seller |
If your goal is long-term storage or a building project that saves you rent, the math often shows the investment pays for itself in less than three years.
How much is an empty shipping container worth?
Not all empty containers are equal. Two units may look alike but can differ thousands of dollars in value.
Empty containers in shipping-grade condition are usually worth more, with 40ft units between $2,500–$5,000 and 20ft units between $1,800–$3,000.
The real value of an empty container depends on condition, waterproofness, and corrosion level. Shipping-grade containers meet strict ocean transport standards, which raises the price. Storage-grade containers may cost less but cannot ship internationally. I tell buyers that the first five years after purchase is the fastest depreciation period. Past that point, prices tend to level out. This is why a well-maintained 5-year-old container often strikes the best balance between cost and utility.
Key drivers of empty container value
| Attribute | Higher Value When… | Reason |
|---|---|---|
| Condition | Minimal damage, waterproof | Can still be used at sea and for high-end clients |
| Certification | Valid CSC plate | Required for international trade |
| Size | Larger units ($/cubic ft) cheaper | Greater flexibility for storage or conversion projects |
| Market supply | Low supply in local area | Shortages lift resale and buy prices |
| Paint and coating | Recent professional coating | Extends lifespan, reduces immediate repairs needed |
If you only need storage, you may get a better deal with a storage-grade container. If you plan cross-border shipping, you must pay extra for certified ones.
What is the resale value of a 40ft container?
Buyers often forget to check resale potential. This can make a big difference to total ownership cost.
A good 40ft container can retain 60%–75% of its purchase value after 3–5 years if properly maintained.
In my consulting work, I see that 40ft units lose about 8%–10% of their value each year in normal use. I worked with a client who bought a high-cube 40ft for $3,200 and sold it four years later for $2,300. That client also saved more than $6,500 by avoiding warehouse rent during that time. So even though he sold it for less than he paid, the overall return was very high.
How resale value changes over time
| Years Owned | Typical Value Kept | Reason for Change |
|---|---|---|
| 1 | 90%–95% | Minimal wear if well kept |
| 3 | 65%–75% | Weathering and minor rust |
| 5 | 50%–65% | Requires repaint, more corrosion |
| 8+ | <50% | End of most cost-effective lifespan |
If you plan to resell, buy at the age when containers have already passed their steepest depreciation, but still have years of strong service left.
Conclusion
Used storage containers can be a smart buy when the price, condition, and use align, offering both cost savings and strong resale potential.
