The ROK Trading Post allows you to send Food, Wood, Stone, and Gold to another member of your alliance. Upgrading the building increases the amount you can transport in one trip and reduces the percentage removed as transport tax.
The Trading Post tax becomes 10% at level 24. At that level, you can send up to 2,000,000 resources in one trip. Meanwhile, level 25 increases capacity to 2,500,000 and lowers the tax to 8%.
- 10% tax: Trading Post level 24
- Lowest standard tax: 8% at level 25
- Level 24 capacity: 2,000,000 resources
- Level 25 capacity: 2,500,000 resources
- Main use: Alliance support and farm-account transfers
- Important limitation: The trader occupies a dispatch queue and must travel between cities
What Is the Trading Post in Rise of Kingdoms?
The Trading Post is an economic building used to transfer personal resources between members of the same alliance. It is especially useful for supporting players during war and moving resources from farm accounts to a main account.
However, resources do not appear instantly in the recipient’s city. Instead, a trader leaves your city, travels to the recipient, delivers the resources, and returns.
How a Resource Transfer Works
- Select an eligible alliance member.
- Choose Food, Wood, Stone, or Gold.
- Enter the amount you want to send.
- Review the transportation capacity and tax.
- Dispatch the trader.
- Wait for the trader to reach the recipient.
- The trader returns before the dispatch queue becomes available again.
Because the trader uses a normal dispatch queue, an urgent transfer can interfere with gathering, Barbarian farming, reinforcements, or field marches. Therefore, check your available queues before sending a large shipment.
Does Distance Affect Resource Transfers?
Yes. The farther the recipient is from your city, the longer the trader needs to deliver the resources and return.
For farm accounts, placing the farm close to the main account can provide several benefits:
- Faster delivery
- Faster return of the dispatch queue
- More transfers during a limited time window
- Easier coordination during KvK
- Lower risk of a critical shipment arriving too late
How Trading Post Tax Works
The Trading Post removes a percentage of every resource shipment as transport tax. Consequently, the recipient receives less than the amount removed from the sender’s city.
Resources Received Formula
Resources received = Amount sent × (1 − tax rate)
For example, a 10% tax rate means the recipient receives 90% of the shipment.
Required Send Amount Formula
Amount to send = Target delivery ÷ (1 − tax rate)
Always round the required send amount upward when the calculation produces a decimal. Otherwise, the recipient may receive slightly less than the requested total.
Trading Post Tax Examples
| Trading Post Level | Tax Rate | Send 1,000,000 | Tax Lost |
| 16 | 20% | Recipient receives 800,000 | 200,000 |
| 21 | 15% | Recipient receives 850,000 | 150,000 |
| 24 | 10% | Recipient receives 900,000 | 100,000 |
| 25 | 8% | Recipient receives 920,000 | 80,000 |
How Much Must You Send to Deliver One Million?
| Tax Rate | Approximate Amount to Send | Approximate Tax |
| 20% | 1,250,000 | 250,000 |
| 15% | 1,176,471 | 176,471 |
| 10% | 1,111,112 | Approximately 111,112 |
| 8% | 1,086,957 | Approximately 86,957 |
What Level Does Trading Post Tax Become 10%?
The transport tax becomes 10% at Trading Post level 24. This level also raises transportation capacity to 2,000,000 resources per trip.
Level 24 is an important milestone for two reasons:
- It reduces resource loss during regular farm-account transfers.
- It is part of the late-game building progression required before City Hall level 25.
At level 25, the tax falls to 8%. Nevertheless, the final upgrade requires substantial resources, construction time, and a Master’s Blueprint. Therefore, level 24 is often the practical efficiency target for an active farm account.

Important Trading Post Level Milestones
Not every level provides the same practical value. Instead, farm accounts should plan around meaningful tax and capacity milestones.
| Level | Tax | Capacity | Recommended Use |
| 15 | 21% | 800,000 | Occasional small transfers |
| 16 | 20% | 900,000 | First clear tax milestone |
| 21 | 15% | 1,400,000 | Regular resource support |
| 24 | 10% | 2,000,000 | Efficient active farm account |
| 25 | 8% | 2,500,000 | Maximum standard efficiency |
Best Trading Post Level for a Farm Account
The correct level depends on how frequently the farm sends resources and how much development the account can afford.
Casual Farm Account
A casual farm that sends small shipments only occasionally can stop around levels 15 or 16. However, a 20% to 21% tax still removes a large share of every transfer.
Active Farm Account
Level 21 provides a useful middle ground with 15% tax and 1,400,000 capacity. As a result, it suits accounts that transfer resources regularly but are not ready for the cost of level 24.
KvK Farm Account
Level 24 is the strongest practical target for a farm that supports frequent healing, training, and war expenses. The 10% tax substantially reduces long-term resource loss.
Level 25 Farm Account
Level 25 provides the lowest standard tax and maximum capacity. Nevertheless, the final upgrade is expensive and uses a Master’s Blueprint. Complete it only when the farm is sufficiently developed and will continue transferring large volumes.
Main Account Priority
A main account eventually needs Trading Post level 24 for late City Hall progression. Therefore, even players who rarely send resources should not neglect it permanently.
The Trading Post is only one part of city progression. Review the Rise of Kingdoms buildings guide to compare it with the Academy, Alliance Center, Hospital, Castle, Wall, and other important structures.
How to Send Resources Efficiently
- Confirm the recipient. Make sure the correct alliance member is selected.
- Ask which resource is needed. Do not assume that every player needs Food.
- Confirm the required delivered amount. The amount sent and received are different.
- Calculate the tax. Use the current Trading Post percentage.
- Check capacity. Split oversized transfers into organized batches.
- Reduce travel distance. Move closer when safe and practical.
- Check dispatch queues. Do not block an essential march slot.
- Send the resources. Confirm the shipment before dispatching.
- Verify delivery. Ask the recipient to confirm the final amount.
Using the Trading Post During KvK
During KvK, farms commonly support healing, troop training, building, and technology expenses. Timing is especially important because hospital demand can rise rapidly during active fighting.
KvK Transfer Checklist
- Transfer resources before the main account reaches an emergency.
- Ask which resource is currently limiting healing.
- Calculate tax before promising a specific delivery.
- Keep the farm close when the map and alliance plan allow it.
- Avoid using the final dispatch queue at a critical moment.
- Send manageable batches instead of one disorganized transfer.
- Do not leave a large transferred stockpile exposed unnecessarily.
- Follow kingdom and alliance rules concerning farm accounts.
Moreover, avoid sending large amounts immediately before the recipient teleports or leaves the alliance. Confirm the planned location and timing first.
Trading Post Side Quest Rewards
Several Trading Post levels also complete Commercial Wizard side quests. These rewards help offset a small portion of the upgrade cost.
| Quest | Reward |
| Upgrade Trading Post to level 2 | 1,000 Wood and 1,000 Food |
| Upgrade Trading Post to level 3 | 1,250 Wood and 2,750 Food |
| Upgrade Trading Post to level 4 | 2,000 Wood and 3,750 Food |
| Upgrade Trading Post to level 5 | 9,000 Wood and 12,750 Food |
| Upgrade Trading Post to level 16 | 52,250 Food, 79,000 Wood, and 31,000 Stone |
| Upgrade Trading Post to level 17 | 118,500 Food, 78,250 Wood, and 46,500 Stone |
| Upgrade Trading Post to level 18 | 178,000 Food, 119,250 Wood, and 71,000 Stone |
| Upgrade Trading Post to level 19 | 268,250 Food, 178,750 Wood, and 106,250 Stone |
| Upgrade Trading Post to level 20 | 403,500 Food, 268,000 Wood, and 159,250 Stone |
Common Trading Post Mistakes
- Assuming sent resources equal received resources: The tax is deducted before delivery.
- Promising a delivery without calculating tax: The recipient receives less than expected.
- Keeping an active farm at a high tax rate: Repeated losses become substantial.
- Sending resources across unnecessary distances: The trader takes longer to return.
- Blocking the final dispatch queue: Military or gathering activity may be delayed.
- Sending the wrong resource: Ask what the recipient needs first.
- Ignoring capacity: Large shipments may require several trips.
- Upgrading every farm to level 25 automatically: The final upgrade may not justify its cost.
- Using an outdated unlock requirement: Check the live building panel.
- Ignoring City Hall progression: The main account eventually needs Trading Post level 24.
- Leaving transferred resources exposed: Coordinate timing during war.
- Confusing personal resources with Alliance Resources: The Trading Post transfers personal city resources.

The Trading Post is used to send resources to eligible members of your alliance. Confirm the recipient through the current Trading Post interface.
Does the trader use a dispatch queue?
Yes. The trader occupies a dispatch queue while traveling to the recipient and returning to your city.
Why is Trading Post level 24 important?
It reduces the tax to 10%, raises capacity to 2,000,000, and is an important requirement in the progression toward City Hall level 25.
How much must I send for another player to receive one million resources?
At a 10% tax rate, send approximately 1,111,112 resources. At an 8% rate, send approximately 1,086,957.
Comparing developed starting options? An upgraded Trading Post reduces the cost of moving resources, but it does not replace gathering commanders, economic technology, farms, or city progression. Players comparing available ROK accounts should also review building levels, technology, resources, commanders, VIP level, migration eligibility, and kingdom status.
Conclusion
The Trading Post becomes increasingly valuable as your resource transfers grow. Lower levels may support occasional shipments, while level 21 provides a practical middle point for regular farm use.
For active farms and KvK support, level 24 is the most important target because it reduces tax to 10% and raises capacity to 2,000,000. Meanwhile, level 25 offers maximum standard efficiency with an 8% tax rate.
Before sending resources, calculate the tax, check transportation capacity, confirm the recipient’s needs, and keep the trader’s travel distance manageable. As a result, fewer resources are wasted and urgent shipments arrive more reliably.
