Formula Used
This calculator gives an estimated lineup score. It is not an official matchmaker rule. It uses the highest vehicle battle rating as the base. Then it checks the average of the top three vehicles. A large gap between the best vehicle and support vehicles adds risk.
Effective BR = top BR + spread penalty + depth bonus + crew bonus + modification bonus + backup bonus + mode adjustment + manual modifier + risk adjustment.
The final value is rounded to the nearest one third step. This matches common rating spacing. The match range then shows a simple one point lower and higher bracket estimate.
How to Use This Calculator
Enter the battle mode first. Add the battle ratings for your strongest vehicles. Use zero for empty slots. Add the number of usable vehicles in your lineup. Then enter crew skill, modification completion, backup count, and risk factor. Press the calculate button. The result appears above the form and below the header. Use the CSV or PDF button to save the result.
Advanced Planning Guide
Why Battle Rating Planning Matters
A strong War Thunder lineup is not only about one powerful vehicle. It also depends on backup strength, crew readiness, and how close your support vehicles are to the top machine. This calculator helps you inspect that balance before joining a match.
Building a Stable Lineup
Start with your highest rated vehicle. Then add support vehicles that stay close to that value. A lineup with one strong tank and several weak backups can feel difficult. You may win the first fight, but later spawns can become risky. This tool highlights that gap by comparing the top three vehicles.
Understanding Crew and Modifiers
Crew skill and modification progress can change how a vehicle feels in battle. A spaded vehicle with trained crew may perform better than a new stock vehicle at the same rating. The calculator adds small readiness bonuses for those factors. These bonuses do not replace official ratings. They only help you judge practical strength.
Using Risk Controls
The risk factor lets you test safer or harder assumptions. A positive value simulates tougher matchmaking pressure. A negative value gives a more cautious estimate. The manual modifier helps when a vehicle feels stronger or weaker than its displayed number.
Reading the Result
The estimated effective rating gives a quick planning number. The match range shows a simple bracket around it. The lineup status explains whether your support vehicles are close enough. A balanced result means your team has better spawn depth. A high gap means you should consider adding stronger backups, lowering the top vehicle, or changing the lineup.
Best Use Cases
Use this calculator before grinding, squad play, event preparation, or testing a new preset. Export the result when comparing nations, modes, or vehicle groups. The saved files make it easier to review choices later.
FAQs
Is this an official battle rating calculator?
No. It is a planning tool. It estimates lineup strength from entered values, support depth, crew skill, modifications, backups, and selected mode.
Why does the highest vehicle matter most?
The strongest vehicle usually sets the main challenge level. Weak support vehicles can make later spawns harder, so the calculator also checks the top three average.
Can I use this for tanks, aircraft, or naval lineups?
Yes. Enter the visible rating values for the vehicles you plan to use. The estimate works as a general lineup comparison method.
What does lineup gap mean?
Lineup gap is the difference between your top vehicle and the average of your strongest three vehicles. A smaller gap usually means better backup strength.
What does the risk factor do?
The risk factor lets you test harder or safer expectations. Increase it for tougher planning. Decrease it when you want a cautious estimate.
Why are crew skill and modifications included?
They reflect practical readiness. Better crews and completed modifications can improve performance, even when the displayed vehicle rating stays unchanged.
How should I use the manual modifier?
Use it for personal judgment. Add a small positive value for very strong vehicles. Use a negative value for weak, stock, or difficult vehicles.
Can I export my results?
Yes. After calculation, use the CSV or PDF button. These files help compare lineups, modes, and future preset changes.
